The mental health and traumatic experiences of mothers of children with 22q11DS.

Background: 22q11 Deletion Syndrome (22q11DS) is the most common microdeletion syndrome with broad phenotypic variability, leading to significant morbidity and some mortality. The varied health problems associated with 22q11DS and the evolving phenotype (both medical and developmental/behavioural) across the lifespan can strongly impact the mental health of patients as well as their caregivers. Like caregivers of children with other chronic diseases, caregivers of children with 22q11DS may experience an increased risk of traumatisation and mental health symptoms.Objective: The study's primary objective was to assess the frequency of traumatic experiences and mental health symptoms among mothers of children with 22q11DS. The secondary objective was to compare their traumatic experiences to those of mothers of children with other neurodevelopmental disorders (NDDs).Method: A total of 71 mothers of children diagnosed with 22q11DS completed an online survey about their mental health symptoms and traumatic experiences. Descriptive statistics were used to summarise the prevalence of their mental health symptoms and traumatic experiences. Logistic regression models were run to compare the traumatic experiences of mothers of children with 22q11DS to those of 335 mothers of children with other neurodevelopmental disorders (NDDs).Results: Many mothers of children with 22q11DS experienced clinically significant mental health symptoms, including depression (39%), anxiety (25%), and post-traumatic stress disorder (PTSD) symptoms (30%). The types of traumatic events experienced by mothers of children with 22q11DS differed from those of mothers of children with other NDDs as they were more likely to observe their child undergoing a medical procedure, a life-threatening surgery, or have been with their child in the intensive care unit.Conclusion: 22q11DS caregivers are likely to require mental health support and trauma-informed care, tailored to the specific needs of this population as they experience different kinds of traumatic events compared to caregivers of children with other NDDS.

Mothers of children with 22q11DS experience clinically significant levels of depression, anxiety, and PTSD.Mothers of children with 22q11DS experience many and diverse trauma particularly related to medical interventions of their child.The types of traumatic events experienced by mothers of children with 22q11DS are different from those of the mothers of children with other neurodevelopmental disorders.

An Online Psychological Program for Adolescents and Young Adults With Headaches: Iterative Design and Rapid Usability Testing.

BACKGROUND: Headache disorders are common, debilitating health problems. Cognitive-behavioral therapy (CBT) is recommended but rarely easily available. With the use of the internet and communication technologies among youth and young adults, these individuals could be self-trained in CBT skills. There is an increasing number of internet-based interventions for headaches, but there has been little research into the usability of these interventions because evaluating usability across the intervention development life cycle is costly. We developed an internet-based CBT program, the Specialized Program for Headache Reduction (SPHERE). While developing it, we aimed to improve SPHERE through rapid usability testing cycles. OBJECTIVE: This study aims to presents a rapid and affordable usability testing approach that can be performed throughout the intervention development life cycle. This paper also provides evidence of the usability of SPHERE. METHODS: We used the "think aloud" usability testing method based on Krug's approach to test user interaction within a lab setting. This was followed by a short posttest interview. We planned to test SPHERE with 3-5 participants testing the same part of the program each cycle. Both the design and development team and the research team actively participated in the usability testing process. Observers independently identified the top 3 usability issues, rated their severity, and conducted debriefing sessions to come to consensus on major issues and generate potential solutions. RESULTS: The testing process allowed major usability issues to be identified and rectified rapidly before piloting SPHERE in a real-world context. A total of 2 cycles of testing were conducted. Of the usability issues encountered in cycles 1 and 2, a total of 68% (17/25) and 32% (12/38), respectively, were rated as major, discussed, and fixed. CONCLUSIONS: This study shows that rapid usability testing is an essential part of the design process that improves program functionality and can be easy and inexpensive to undertake.

Reward Behavior Disengagement, a Neuroeconomic Model-Based Objective Measure of Reward Pathology in Depression: Findings from the EMBARC Trial.

The probabilistic reward task (PRT) has identified reward learning impairments in those with major depressive disorder (MDD), as well as anhedonia-specific reward learning impairments. However, attempts to validate the anhedonia-specific impairments have produced inconsistent findings. Thus, we seek to determine whether the Reward Behavior Disengagement (RBD), our proposed economic augmentation of PRT, differs between MDD participants and controls, and whether there is a level at which RBD is high enough for depressed participants to be considered objectively disengaged. Data were gathered as part of the Establishing Moderators and Biosignatures of Antidepressant Response in Clinical Care (EMBARC) study, a double-blind, placebo-controlled clinical trial of antidepressant response. Participants included 195 individuals with moderate to severe MDD (Quick Inventory of Depressive Symptomatology (QIDS-SR) score ≥ 15), not in treatment for depression, and with complete PRT data. Healthy controls (n = 40) had no history of psychiatric illness, a QIDS-SR score < 8, and complete PRT data. Participants with MDD were treated with sertraline or placebo for 8 weeks (stage I of the EMBARC trial). RBD was applied to PRT data using discriminant analysis, and classified MDD participants as reward task engaged (n = 137) or reward task disengaged (n = 58), relative to controls. Reward task engaged/disengaged groups were compared on sociodemographic features, reward-behavior, and sertraline/placebo response (Hamilton Depression Rating Scale scores). Reward task disengaged MDD participants responded only to sertraline, whereas those who were reward task engaged responded to sertraline and placebo (F(1293) = 4.33, p = 0.038). Reward task engaged/disengaged groups did not differ otherwise. RBD was predictive of reward impairment in depressed patients and may have clinical utility in identifying patients who will benefit from antidepressants.

Paraprofessional delivery of online narrative exposure therapy for firefighters.

Firefighters are at increased risk for developing posttraumatic stress disorder (PTSD) and face numerous barriers to accessing mental health care. Innovative ways to increase access to evidence-based interventions are needed. This study was a case series testing the acceptability, feasibility, and preliminary effectiveness of a paraprofessional-delivered, virtual narrative exposure therapy (eNET) intervention for PTSD. Participants were 21 firefighters who met the criteria for clinical or subclinical probable PTSD and completed 10-12 sessions of eNET via videoconference. Participants completed self-report measures pre- and postintervention and at 2- and 6-month follow-ups as well as a postintervention qualitative interview. Paired samples t tests evidenced statistically significant decreases in PTSD, anxiety, and depressive symptom severity and functional impairment from pre- to postintervention, ds = 1.08-1.33, and in PTSD and anxiety symptom severity and functional impairment from preintervention to 6-month follow-up, ds = 0.69-1.10. The average PTSD symptom severity score fell from above to below the clinical cutoff for probable PTSD at postintervention and follow-ups. Qualitative interviews indicated that paraprofessionals were considered central to participants' success and experience with the intervention. No adverse events or safety concerns were raised. This study is an important step in demonstrating that appropriately trained and supervised paraprofessionals can effectively deliver eNET to firefighters with PTSD.

Alterations in resting-state functional activity and connectivity for major depressive disorder appetite and weight disturbance phenotypes.

BACKGROUND: Major depressive disorder (MDD) is often accompanied by changes in appetite and weight. Prior task-based functional magnetic resonance imaging (fMRI) findings suggest these MDD phenotypes are associated with altered reward and interoceptive processing. METHODS: Using resting-state fMRI data, we compared the fractional amplitude of low-frequency fluctuations (fALFF) and seed-based connectivity (SBC) among hyperphagic (n = 77), hypophagic (n = 66), and euphagic (n = 42) MDD groups and a healthy comparison group (n = 38). We examined fALFF and SBC in a mask restricted to reward [nucleus accumbens (NAcc), putamen, caudate, ventral pallidum, and orbitofrontal cortex (OFC)] and interoceptive (anterior insula and hypothalamus) regions and also performed exploratory whole-brain analyses. SBC analyses included as seeds the NAcc and also regions demonstrating group differences in fALFF (i.e. right lateral OFC and right anterior insula). All analyses used threshold-free cluster enhancement. RESULTS: Mask-restricted analyses revealed stronger fALFF in the right lateral OFC, and weaker fALFF in the right anterior insula, for hyperphagic MDD v. healthy comparison. We also found weaker SBC between the right lateral OFC and left anterior insula for hyperphagic MDD v. healthy comparison. Whole-brain analyses revealed weaker fALFF in the right anterior insula, and stronger SBC between the right lateral OFC and left precentral gyrus, for hyperphagic MDD v. healthy comparison. Findings were no longer significant after controlling for body mass index, which was higher for hyperphagic MDD. CONCLUSIONS: Our results suggest hyperphagic MDD may be associated with altered activity in and connectivity between interoceptive and reward regions.

How to measure barriers in accessing mental healthcare? Psychometric evaluation of a screening tool in parents of children with intellectual and developmental disabilities.

Caring for children with intellectual and developmental disabilities (IDD) can cause an enormous physical and emotional burden, and therefore these parents have an elevated risk to experience mental health problems. The characteristics of current healthcare systems and parents' responsibilities to care for their children seem to impede their access to mental healthcare. There is so far a lack of instruments to screen for such obstacles. The aim of this study was to develop and validate a scale for measuring barriers to accessing mental healthcare. The Parental Healthcare Barriers Scale (PHBS) was developed on the basis of an extensive literature research, input and discussion from experts and parents with lived experience. A cross-sectional survey was used to collect data from 456 parents of children with IDD. Physical health, mental health, social support, and parenting were measured for concurrent and discriminant validity of the PHBS. The PHBS scale revealed acceptable to good reliability and validity. It consists of four subscales (i.e., support accessibility, personal belief, emotional readiness, and resource availability). The PHBS found parents prioritized their children's treatments over their own mental health challenges (93.4%), did not have enough time (90.4%), and had financial concerns (85.8%). Parents in rural and remote areas had more limited resources. Findings from our study suggest increasing financial support for the parents seeking mental health services, introducing evidence-based treatments, increasing the availability of healthcare services for parents, and adjusting current services to their needs.

A randomized controlled trial evaluating the effect of an internet-based cognitive-behavioral program on anxiety symptoms in a community-based sample of adolescents.

Adolescents' use of online resources to self-manage anxiety is growing. The objective of the current trial was to assess the effectiveness of an online, primarily self-led cognitive behavioral therapy (CBT) program in reducing anxiety symptoms compared to an active comparator, access to anxiety resources on a static website. A total of 563 adolescents (13-19 years) with self-identified anxiety concerns were enrolled. Self-reported anxiety symptoms were assessed pre- and post-intervention (6 weeks). Adolescents were further assessed 3 months post-intervention. Other outcomes assessed at the three time-points were quality of life (QOL) and healthcare utilization. Both interventions reduced anxiety symptoms after use. Group differences in symptom change were not significant post-intervention (p = 0.16), but were at 3 months (favouring online CBT; p = 0.04) with male participants reporting more symptom change (p = 0.03). Across time-points, as anxiety symptoms decreased, QOL increased (p < 0.001). Among participants that provided healthcare utilization before and after intervention use, the greatest changes in use were among online CBT users particularly for mental health provider visits (psychiatrist, -41.0 % vs. +18.5 %; social worker, -42.5 % vs. -22.1 %), hospital-based care (emergency department visits, -80.0 % vs. +79.4 %; hospital admissions, -76.1 % vs. +42.9 %), and use of self-help or alternative treatments (-60.0 % vs. +6.6 %). Results suggest that, over time, use of online CBT by adolescents can result in improved anxiety symptoms and fewer use of other healthcare resources compared to traditional online information seeking.

Risk and protective factors for posttraumatic stress and posttraumatic growth in parents of children with intellectual and developmental disorders.

Background: Parents of children with intellectual and developmental disorders often experience potentially traumatic events while caring for their children. Heightened posttraumatic stress (PTS) and posttraumatic growth (PTG) have been found in this population. Objective: We aimed to explore risk and protective factors for their PTS and PTG. Method: A cross-sectional study was conducted with 385 parents (average age M = 43.14 years, SD = 7.40; 95.3% mothers). Results: Parenting trauma showed an adverse effect on developing PTS (beta = 0.25, p < .01) and a positive role in promoting PTG (beta = 0.16, p < .01). Social support was protective in its correlation with lower levels of PTS (beta = -0.12, p < .01) and higher levels of PTG (beta = 0.22, p < .01). Barriers to care were associated with increased PTS (beta = 0.23, p < .01), but unrelated to PTG (beta = .01, p = .855). Negative parenting showed a significant, but small, correlation with more severe PTS (beta = 0.11, p < .05), and was unrelated to PTG (beta = -0.09, p = .065). Conclusions: Our study increases the understanding of posttraumatic reactions in parents, predominantly mothers, of children with IDD and identified parenting-related trauma, social support, and barriers to mental health care as predictive factors of the reactions. More research is needed to confirm and validate the effects of the discussed factors. Although causation can not be inferred, prompt and adequate screening and therapeutic resources should be provided to those mothers who were exposed to multiple stressful caregiving events and had limited healthcare access and less support from their spouses, peers, and caregiving partners. HIGHLIGHTS: Parents of a child with Intellectual and Developmental Disorders with parenting trauma had higher posttraumatic stress (PTS) and posttraumatic growth (PTG).Social support was related to lower PTS and higher PTG.Barriers to care were related to higher PTS but unrelated to PTG.

Antecedentes: Los padres de niños con trastornos intelectuales y del desarrollo a menudo experimentan eventos potencialmente traumáticos mientras cuidan a sus hijos. En esta población se han encontrado un elevado estrés postraumático (PTS por sus siglas en ingles) y crecimiento postraumático (PTG por sus siglas en ingles).Objetivo: Nuestro objetivo fue explorar los factores protectores y de riesgo para PTS y PTG.Método: Se realizó un estudio transversal con 385 padres (con edad promedio M = 43,14 años, DS = 7,40; 95,3% madres).Resultados: El trauma parental mostró ser un efecto adverso en el desarrollo de PTS (beta = 0.25, p < 0.01) y un papel positivo en la promover el PTG (beta = 0.16, p < 0,01). El apoyo social fue protector en su correlación con niveles más bajos de PTS (beta = −0.12, p < .01) y niveles más altos de PTG (beta = 0.22, p < .01). Las barreras a la atención se asociaron con un aumento de PTS (beta = 0.23, p < 0.01), pero no se relacionaron con PTG (beta = 0.01, p = 0,855). La crianza negativa mostró una correlación significativa, pero pequeña, con PTS más severos (beta = 0.11, p < 0,05) y no estuvo relacionado con el PTG (beta = −0.09, p = 0.065).Conclusiones: Nuestro estudio aumenta la comprensión de las reacciones postraumáticas en los padres, predominantemente madres, de niños con IDD e identificó el trauma relacionado con la crianza, el apoyo social y las barreras para la atención de la salud mental como factores predictivos de estas reacciones. Se necesita más investigación para confirmar y validar los efectos de los factores discutidos. Si bien no se puede inferir causalidad, se deben proporcionar recursos terapéuticos y de detección, rápidos y adecuados, a aquellas madres que estuvieron expuestas a múltiples eventos estresantes del cuidado y tuvieron acceso limitado a la atención médica y menos apoyo de sus cónyuges, compañeros y cuidadores.

Dynamic Resting-State Network Biomarkers of Antidepressant Treatment Response.

BACKGROUND: Delivery of effective antidepressant treatment has been hampered by a lack of objective tools for predicting or monitoring treatment response. This study aimed to address this gap by testing novel dynamic resting-state functional network markers of antidepressant response. METHODS: The Establishing Moderators and Biosignatures of Antidepressant Response in Clinical Care (EMBARC) study randomized adults with major depressive disorder to 8 weeks of either sertraline or placebo, and depression severity was evaluated longitudinally. Participants completed resting-state neuroimaging pretreatment and again after 1 week of treatment (n = 259 eligible for analyses). Coactivation pattern analyses identified recurrent whole-brain states of spatial coactivation, and computed time spent in each state for each participant was the main dynamic measure. Multilevel modeling estimated the associations between pretreatment network dynamics and sertraline response and between early (pretreatment to 1 week) changes in network dynamics and sertraline response. RESULTS: Dynamic network markers of early sertraline response included increased time in network states consistent with canonical default and salience networks, together with decreased time in network states characterized by coactivation of cingulate and ventral limbic or temporal regions. The effect of sertraline on depression recovery was mediated by these dynamic network changes. In contrast, early changes in dynamic functioning of corticolimbic and frontoinsular-default networks were related to patterns of symptom recovery common across treatment groups. CONCLUSIONS: Dynamic resting-state markers of early antidepressant response or general recovery may assist development of clinical tools for monitoring and predicting effective intervention.

Serotonin-norepinephrine reuptake inhibitor antidepressant effects on regional connectivity of the thalamus in persistent depressive disorder: evidence from two randomized, double-blind, placebo-controlled clinical trials.

Previous neuroimaging studies have shown that serotonin-norepinephrine reuptake inhibitor antidepressants alter functional activity in large expanses of brain regions. However, it is not clear how these regions are systemically organized on a connectome level with specific topological properties, which may be crucial to revealing neural mechanisms underlying serotonin-norepinephrine reuptake inhibitor treatment of persistent depressive disorder. To investigate the effect of serotonin-norepinephrine reuptake inhibitor antidepressants on brain functional connectome reconfiguration in persistent depressive disorder and whether this reconfiguration promotes the improvement of clinical symptoms, we combined resting-state functional magnetic resonance imaging (fMRI) scans acquired in two randomized, double-blind, placebo-controlled trial studies of serotonin-norepinephrine reuptake inhibitor antidepressant treatment of patients with persistent depressive disorder. One was a randomized, double-blind, placebo-controlled trial of 10-week duloxetine medication treatment, which included 17 patients in duloxetine group and 17 patients in placebo group (ClinicalTrials.gov Identifier: NCT00360724); the other one was a randomized, double-blind, placebo-controlled trial of 12-week desvenlafaxine medication treatment, which included 16 patients in desvenlafaxine group and 15 patients in placebo group (ClinicalTrials.gov Identifier: NCT01537068). The 24-item Hamilton Depression Rating Scale was used to measure clinical symptoms, and graph theory was employed to examine serotonin-norepinephrine reuptake inhibitor antidepressant treatment effects on the topological properties of whole-brain functional connectome of patients with persistent depressive disorder. We adopted a hierarchical strategy to examine the topological property changes caused by serotonin-norepinephrine reuptake inhibitor antidepressant treatment, calculated their small-worldness, global integration, local segregation and nodal clustering coefficient in turn. Linear regression analysis was used to test associations of treatment, graph properties changes and clinical symptom response. Symptom scores were more significantly reduced after antidepressant than placebo administration (η 2 = 0.18). There was a treatment-by-time effect that optimized the functional connectome in a small-world manner, with increased global integration and increased nodal clustering coefficient in the bilateral thalamus (left thalamus η 2 = 0.21; right thalamus η 2 = 0.23). The nodal clustering coefficient increment of the right thalamus (ratio = 29.86; 95% confidence interval, -4.007 to -0.207) partially mediated the relationship between treatment and symptom improvement, and symptom improvement partially mediated (ratio = 21.21; 95% confidence interval, 0.0243-0.444) the relationship between treatment and nodal clustering coefficient increments of the right thalamus. Our study may indicate a putative mutually reinforcing association between nodal clustering coefficient increment of the right thalamus and symptom improvement from serotonin-norepinephrine reuptake inhibitor antidepressant treatments with duloxetine or desvenlafaxine.

Effectiveness of an Internet-Based and Telephone-Assisted Training for Parents of 4-Year-Old Children With Disruptive Behavior: Implementation Research.

BACKGROUND: There is a lack of effectiveness studies when digital parent training programs are implemented in real-world practice. The efficacy of the internet-based and telephone-assisted Finnish Strongest Families Smart Website (SFSW) parent training intervention on the disruptive behavior of 4-year-old children was studied in a randomized controlled trial setting in Southwest Finland between 2011 and 2013. After that, the intervention was implemented nationwide in child health clinics from 2015 onwards. OBJECTIVE: The main aim of this study was to compare the treatment characteristics and effectiveness of the SFSW parent training intervention between the families who received the intervention when it was implemented as a normal practice in child health clinics and the families who received the same intervention during the randomized controlled trial. METHODS: The implementation group comprised 600 families who were recruited in the SFSW intervention between January 2015 and May 2017 in real-world implementation. The RCT intervention group comprised 232 families who were recruited between October 2011 and November 2013. The same demographic and child and parent measures were collected from both study groups and were compared using linear mixed-effect models for repeated measurements. The child psychopathology and functioning level were measured using the Child Behavior Checklist (CBCL) version 1.5-5 for preschool children, the Inventory of Callous-Unemotional Traits (ICU), and a modified version of the Barkley Home Situations Questionnaire. Parenting skills were measured using the 31-item Parenting Scale and the shorter 21-item Depression, Anxiety and Stress Scale (DASS-21). The estimated child and parent outcomes were adjusted for CBCL externalizing scores at baseline, maternal education, duration of the behavior problems, and paternal age. The baseline measurements of each outcome were used as covariates. RESULTS: The implementation group was more likely to complete the intervention than the RCT intervention group (514/600, 85.7% vs 176/232, 75.9%, respectively; P<.001). There were no significant differences between the implementation and RCT intervention groups with regard to child measures, including CBCL externalizing score (-0.2, 95% CI -1.3 to 1.6; P=.83), total score (-0.7, 95% CI -3.0 to 4.5; P=.70), internalizing score (-0.3, 95% CI -1.0 to 1.6; P=.64), and ICU total score (-0.4, 95% Cl -1.9 to 1.2; P=.64). No significant difference was detected in the Parenting Scale total score (0.0, 95% Cl -0.1 to 0.1; P=.50), while DASS-21 total score differed nearly significantly (2.5, 95% Cl 0.0-5.1; P=.05), indicating better improvement in the implementation group. CONCLUSIONS: The internet-based and telephone-assisted SFSW parent training intervention was effectively implemented in real-world settings. These findings have implications for addressing the unmet needs of children with disruptive behavior problems. Our initiative could also provide a quick socially distanced solution for the considerable mental health impact of the COVID-19 pandemic.

Resting State MRI Amplitude of Low Frequency Fluctuations Associated With Suicidal Ideation in Bipolar Depression.

Objective: Suicidal ideation (SI) is a risk factor for completed suicide. Our previous resting state functional magnetic resonance imaging (fMRI) study found that higher amplitude of low frequency fluctuation (ALFF) in right hippocampus and thalamus was associated with SI in major depressive disorder (MDD). The present study aimed to evaluate that association in participants with bipolar disorder (BD).Methods: Thirty depressed, adult participants with a DSM-IV diagnosis of BD had resting state fMRI scans. Region-of-interest (ROI) analyses used ALFF values within areas that were previously associated with SI in MDD. Spearman rank correlation and ordinal regression analyses were performed to assess associations between ALFF values and the SI item of the Montgomery-Asberg Depression Rating Scale. Exploratory whole-brain analyses identified regions where ALFF was associated with SI.Results: Within the right hippocampus region, SI was positively associated with ALFF (Spearman R = 0.490, P = .0060). Ordinal regression analysis indicated that for every 0.1-unit increase in ALFF in that region, the odds of having higher SI were increased by 35% (odds ratio = 1.35; 95% confidence interval, 1.08-1.73; P = .012). Within the previously identified thalamus cluster, SI was associated with ALFF only at a trend level (Spearman R = 0.310, P = .069). Whole-brain analyses identified 3 clusters of positive association between SI and ALFF, 1 of which was located in the right hippocampus.Conclusions: This study found that our previous finding of positive association between SI and ALFF in the right hippocampus extended to bipolar depression. Future studies should examine the clinical utility of this association, and the role of the hippocampus in SI.Trial Registration: Data used for this secondary analysis came from studies with ClinicalTrials.gov identifiers NCT02239094 (January 2015 through September 2016) and NCT02473250 (January 2015 through December 2019).

The influence of social support on posttraumatic stress symptoms among children and adolescents: a scoping review and meta-analysis.

Background: Several risk and protective factors play a role in the development of posttraumatic stress symptoms (PTSS) in children and youth. The evidence for social support (SS) as a protective factor is rising; however, a review of the evidence is lacking. Objective: This scoping review and meta-analysis aims to map out and synthesize the present research on the influence of social support on PTSS in children and adolescents. Method: The literature searched through PubMed, MEDLINE, Embase, PsycInfo, and CINAHL identified 3629 abstracts. Ninety articles published from 1999 to 2020 were selected, including a total of 77,439 participants. Results: Most papers focused on social and emotional support from family members (36/88) and peers (26/88); other types of support (e.g., informational support and support from professionals) were not widely reported. The cross-sectional studies illustrated an overall significant, but weak, negative correlation between global social support and PTSS. A similar weak negative association was found between family support and PTSS. The association between peer support and PTSS was not significant. For longitudinal studies, 4 of 5 indicated that SS was a significant negative predictor of PTSS. Conclusions: There was conceptual, methodological, and statistical heterogeneity of the identified studies. This review suggests a weak negative relationship between global SS and PTSS in children and adolescents. Higher global SS was related to less PTSS. The evidence regarding family support revealed a more stable negative relationship with PTSS than that for peer support. Investigating social support without specifying the form of support confounds the effect. Studies on informational, teacher, or professional support seem to be lacking. More studies are needed on the longitudinal effects of SS on PTSS.

Antecedentes: Varios factores de riesgo y de protección influyen en el desarrollo de síntomas de estrés postraumático (SEPT) en niños y jóvenes. La evidencia del apoyo social (AS) como factor protector está aumentando; sin embargo, falta una revisión de la evidencia.Objetivo: Esta revisión de alcance y metaanálisis tiene como objetivo mapear y sintetizar la investigación actual sobre la influencia del apoyo social en el SEPT en niños y adolescentes.Método: La literatura buscada a través de PubMed, MEDLINE, Embase, PsycInfo y CINAHL identificó 3629 resúmenes. Fueron seleccionados Noventa artículos publicados entre 1999 y 2020, incluyendo un total de 77.439 participantes.Resultados: La mayoría de los artículos se centraron en el apoyo social y emocional de los miembros de la familia (36/88) y compañeros (26/88); otros tipos de apoyo (por ejemplo, apoyo informativo y apoyo de profesionales) no se informaron ampliamente. Los estudios transversales ilustraron una correlación negativa global significativa, pero débil, entre el apoyo social global y SEPT (coeficiente de correlación agrupado r = −.09, p < .01). Una débil asociación negativa similar se encontró entre el apoyo familiar y los SEPT (agrupado r = −.12, p < .005). La asociación entre el apoyo de los compañeros y los SEPT no fue significativa, r = −.08, p = .143. Para estudios longitudinales, 4 de 5 indicaron que AS era un predictor negativo significativo de SEPT (rango de tamaño de efecto beta = [−.32, −.21]).Conclusiones: Hubo heterogeneidad conceptual, metodológica y estadística de los estudios identificados. Esta revisión sugiere una débil relación negativa entre AS global y SEPT en niños y adolescentes. Un AS global más alto se relacionó con menos SEPT. La evidencia con respecto al apoyo familiar reveló una relación negativa más estable con SEPT que la del apoyo de pares. Investigar el apoyo social sin especificar la forma de apoyo confunde el efecto. Estudios de apoyo informativo, docente o profesional parecen faltar. Se necesitan más estudios sobre los efectos longitudinales de AS en SEPT.

Neural substrates of emotional conflict with anxiety in major depressive disorder: Findings from the Establishing Moderators and biosignatures of Antidepressant Response in Clinical Care (EMBARC) randomized controlled trial.

BACKGROUND: The brain circuitry of depression and anxiety/fear is well-established, involving regions such as the limbic system and prefrontal cortex. We expand prior literature by examining the extent to which four discrete factors of anxiety (immediate state anxiety, physiological/panic, neuroticism/worry, and agitation/restlessness) among depressed outpatients are associated with differential responses during reactivity to and regulation of emotional conflict. METHODS: A total of 172 subjects diagnosed with major depressive disorder underwent functional magnetic resonance imaging while performing an Emotional Stroop Task. Two main contrasts were examined using whole brain voxel wise analyses: emotional reactivity and emotion regulation. We also evaluated the association of these contrasts with the four aforementioned anxiety factors. RESULTS: During emotional reactivity, participants with higher immediate state anxiety showed potentiated activation in the rolandic operculum and insula, while individuals with higher levels of physiological/panic demonstrated decreased activation in the posterior cingulate. No significant results emerged for any of the four factors on emotion regulation. When re-analyzing these statistically-significant brain regions through analyses of a subsample with (n = 92) and without (n = 80) a current anxiety disorder, no significant associations occurred among those without an anxiety disorder. Among those with an anxiety disorder, results were similar to the full sample, except the posterior cingulate was associated with the neuroticism/worry factor. CONCLUSIONS: Divergent patterns of task-related brain activation across four discrete anxiety factors could be used to inform treatment decisions and target specific aspects of anxiety that involve intrinsic processing to attenuate overactive responses to emotional stimuli.

Parenting-related trauma exposure among parents of children with intellectual and developmental disorders: Development and validation of the Parenting Trauma Checklist.

Parents of children with intellectual and developmental disorders (IDDs) often encounter parenting-related traumatic events. Trauma exposure is a risk factor for mental health problems, including posttraumatic stress disorder (PTSD). Little is known regarding the types of traumatic events that parents commonly experience and how to best assess parenting-related trauma exposure. To address this gap, we developed the Parenting Trauma Checklist (PTC) and tested its psychometric properties. The PTC was created based on an extensive literature review and consultation with stakeholders, which led to the creation of a 17-item instrument. Participants (N = 424) were Canadian parents of children with IDDs who completed an online test battery that included the PTC and several questionnaires to assess PTSD symptoms, global mental and physical health, lifetime trauma exposure, and functional impairment, which were included to test the validity of the new instrument. The PTC demonstrated good construct validity. Ninety four percent of the sample reported parenting-related trauma exposure. Parents reported having experienced an average of 5.79 parenting-related traumatic events, with seeing their child undergo a medical procedure the most frequently endorsed event (68.6%). Experiencing more parenting-related traumatic events was positively associated with higher PTSD symptom levels, r = .35, p < .001. The PTC is a promising instrument that can be used to examine parenting-related trauma exposure. The measure can be used as a screening tool to detect parents' risk of traumatic stress disorders, evaluate traumatic experiences, and assess whether trauma-focused treatment is warranted.

Exploration of baseline and early changes in neurocognitive characteristics as predictors of treatment response to bupropion, sertraline, and placebo in the EMBARC clinical trial.

BACKGROUND: Treatment for major depressive disorder (MDD) is imprecise and often involves trial-and-error to determine the most effective approach. To facilitate optimal treatment selection and inform timely adjustment, the current study investigated whether neurocognitive variables could predict an antidepressant response in a treatment-specific manner. METHODS: In the two-stage Establishing Moderators and Biosignatures of Antidepressant Response for Clinical Care (EMBARC) trial, outpatients with non-psychotic recurrent MDD were first randomized to an 8-week course of sertraline selective serotonin reuptake inhibitor or placebo. Behavioral measures of reward responsiveness, cognitive control, verbal fluency, psychomotor, and cognitive processing speeds were collected at baseline and week 1. Treatment responders then continued on another 8-week course of the same medication, whereas non-responders to sertraline or placebo were crossed-over under double-blinded conditions to bupropion noradrenaline/dopamine reuptake inhibitor or sertraline, respectively. Hamilton Rating for Depression scores were also assessed at baseline, weeks 8, and 16. RESULTS: Greater improvements in psychomotor and cognitive processing speeds within the first week, as well as better pretreatment performance in these domains, were specifically associated with higher likelihood of response to placebo. Moreover, better reward responsiveness, poorer cognitive control and greater verbal fluency were associated with greater likelihood of response to bupropion in patients who previously failed to respond to sertraline. CONCLUSION: These exploratory results warrant further scrutiny, but demonstrate that quick and non-invasive behavioral tests may have substantial clinical value in predicting antidepressant treatment response.

Patterns of Pretreatment Reward Task Brain Activation Predict Individual Antidepressant Response: Key Results From the EMBARC Randomized Clinical Trial.

BACKGROUND: The lack of biomarkers to inform antidepressant selection is a key challenge in personalized depression treatment. This work identifies candidate biomarkers by building deep learning predictors of individual treatment outcomes using reward processing measures from functional magnetic resonance imaging, clinical assessments, and demographics. METHODS: Participants in the EMBARC (Establishing Moderators and Biosignatures of Antidepressant Response in Clinical Care) study (n = 222) underwent reward processing task-based functional magnetic resonance imaging at baseline and were randomized to 8 weeks of sertraline (n = 106) or placebo (n = 116). Subsequently, sertraline nonresponders (n = 37) switched to 8 weeks of bupropion. The change in Hamilton Depression Rating Scale was measured after treatment. Reward processing, clinical measurements, and demographics were used to train treatment-specific deep learning models. RESULTS: The predictive model for sertraline achieved R2 of 48% (95% CI, 33%-61%; p < 10-3) in predicting the change in Hamilton Depression Rating Scale and number-needed-to-treat (NNT) of 4.86 participants in predicting response. The placebo model achieved R2 of 28% (95% CI, 15%-42%; p < 10-3) and NNT of 2.95 in predicting response. The bupropion model achieved R2 of 34% (95% CI, 10%-59%, p < 10-3) and NNT of 1.68 in predicting response. Brain regions where reward processing activity was predictive included the prefrontal cortex and cerebellar crus 1 for sertraline and the cingulate cortex, caudate, orbitofrontal cortex, and crus 1 for bupropion. CONCLUSIONS: These findings demonstrate the utility of reward processing measurements and deep learning to predict antidepressant outcomes and to form multimodal treatment biomarkers.

Online narrative exposure therapy for parents of children with neurodevelopmental disabilities suffering from posttraumatic stress symptoms - study protocol of a randomized controlled trial.

Background: Parents of children with intellectual and neurodevelopmental disorders (IDD) often experience traumatic events in the care of their children. This leads to comparatively high numbers of mental health problems such as posttraumatic stress disorder (PTSD) in those parents. Intervention approaches for parents of children with IDD are scarce and many parents remain without support. Objective: This study aims to test the feasibility and efficacy of online Narrative Exposure Therapy (eNET) with parents of children with IDD. Methods: The study follows a randomized waitlist-control design. eNET is an exposure-based PTSD intervention and includes 8-12 90-minute sessions. All sessions will be conducted via video calls with trained paraprofessionals. We aim to include 50 parents, approximately 25 in the immediate intervention group and 25 in the waitlist group. Waitlist participants will receive the same intervention after a three-month wait period. All participants need to either fulfill full or subclinical PTSD symptoms according to DSM-5. Feasibility and efficacy of the intervention will be measured with pre, post, and 2 and 6 months follow-up surveys focusing on PTSD symptoms. Secondary outcomes include other health-related outcomes such as physical symptoms, depression symptoms, anxiety symptoms and functionality. Conclusions: The proposed study allows us to test the feasibility and efficacy of eNET in a sample of parents of children with IDD. There are so far no published studies on the evidence of eNET; this study is one of the first randomized controlled trials investigating the feasibility and efficacy of eNET and therefore will have implications on further research and practice.Clinical trial registration: NCT04385927Date and version identifier: 22 July 2021.

Antecedentes: Los padres de niños con trastornos intelectuales y del neurodesarrollo (TIND) experimentan con frecuencia eventos traumáticos durante el cuidado de sus hijos. Esto lleva a cifras relativamente altas de problemas de salud mental, tales como el trastorno de estrés postraumático (TEPT), en estos padres. Los abordajes para intervenir a los padres de niños con TIND son escasos y muchos padres continúan sin recibir soporte.Objetivo: El objetivo de este estudio es evaluar la viabilidad y la eficacia de la terapia de exposición narrativa en línea (eNET, por sus siglas en inglés) en padres de niños con TIND.Métodos: El estudio sigue un diseño aleatorizado con el grupo de control asignado a una lista de espera. La eNET es una intervención para el TEPT basada en exposición que incluye 8 a 12 sesiones de 90 minutos cada una. Todas las sesiones se realizarán mediante videollamadas con paraprofesionales entrenados. El objetivo es incluir a 50 padres, aproximadamente 25 en el grupo de intervención inmediata y 25 en el grupo de lista de espera. Los participantes en la lista de espera recibirán la misma intervención luego de un periodo de tres meses de espera. Todos los participantes deben cumplir los criterios para el TEPT según el DSM-5, ya sea de manera completa o subclínica. La viabilidad y la eficacia de la intervención se medirán con encuestas enfocadas en los síntomas del TEPT tomadas antes de la intención, inmediatamente luego de concluirla y a los 2 y a los 6 meses de seguimiento. Los resultados secundarios incluyen a aquellos relacionados con otros factores de la salud tales como síntomas físicos, síntomas de depresión, síntomas de ansiedad y funcionalidad.Conclusiones: El estudio propuesto nos permite evaluar la viabilidad y la eficacia del eNET en una muestra de padres de niños con TIND. Al momento, no existen estudios publicados sobre la evidencia de la eNET; este estudio es uno de los primeros ensayos aleatorizados que investigarán la viabilidad y la eficacia del eNET y, por tanto, tendrá implicancias para ulteriores investigaciones y para la práctica.Registro de ensayo clínico: NCT04385927Fecha e identificador de la versión: Julio 22 del 2021.

An observational cohort study comparing ibuprofen and oxycodone in children with fractures.

OBJECTIVE: To compare the effectiveness and safety of prescribing ibuprofen and oxycodone for at-home management of children's fracture pain. METHODS: A prospective observational cohort was conducted at the Stollery Children's Hospital pediatric emergency department (June 2010-July 2014). Children aged 4-16 years with an isolated fracture discharged home with advice to use either ibuprofen or oxycodone were recruited. RESULTS: A cohort of 329 children (n = 217 ibuprofen, n = 112 oxycodone) were included. Mean age was 11.1 years (SD 3.5); 68% (223/329) were male. Fracture distribution included 80.5% (264/329) upper limb with 34.3% (113/329) requiring fracture reduction. The mean reduction in Faces Pain Score-Revised score (maximum pain-post-treatment pain) for Day 1 was 3.6 (SD 1.9) (ibuprofen) and 3.8 (SD 2.1) (oxycodone) (p = 0.50); Day 2 was 3.6 (SD 1.8) (ibuprofen) and 3.7 (SD 1.6) (oxycodone) (p = 0.56); Day 3 was 3.7 (SD 1.7) (ibuprofen) and 3.3 (SD 1.7) (oxycodone) (p = 0.24). Children prescribed ibuprofen (51.2%, 109/213) experienced less adverse events compared to those prescribed oxycodone (70.5% 79/112) on Day 1 (p = 0.001). Children prescribed ibuprofen (71.8%, 150/209) had their function (eat, play, school, sleep) affected less than those prescribed oxycodone (83.0%, 93/112) (p = 0.03) on Day 1. CONCLUSION: Children prescribed ibuprofen or oxycodone experienced similar analgesic effectiveness for at-home fracture pain. Oxycodone prescribing was associated with more adverse events and negatively impacted function. Oxycodone use does not appear to confer any benefit over ibuprofen for pain relief and has a negative adverse effect profile. Ibuprofen appears to be a safe option for fracture-related pain.

Differential reinforcement learning responses to positive and negative information in unmedicated individuals with depression.

Major depressive disorder (MDD) is characterized by behavioral and neural abnormalities in processing both rewarding and aversive stimuli, which may impact motivational and affective symptoms. Learning paradigms have been used to assess reinforcement encoding abnormalities in MDD and their association with dysfunctional incentive-based behavior, but how the valence and context of information modulate this learning is not well understood. To address these gaps, we examined responses to positive and negative reinforcement across multiple temporal phases of information processing. While undergoing functional magnetic resonance imaging (fMRI), 47 participants (23 unmedicated, predominantly medication-naïve participants with MDD and 24 demographically-matched HC participants) completed a probabilistic, feedback-based reinforcement learning task that allowed us to separate neural activation during motor response (choice) from reinforcement feedback and monetary outcome across two independent conditions: pursuing gains and avoiding losses. In the gain condition, MDD participants showed overall blunted learning responses (prediction error) in the dorsal striatum when receiving monetary outcome, and reduced responses in ventral striatum for positive, but not negative, prediction error. The MDD group showed enhanced sensitivity to negative information, and symptom severity was associated with better behavioral performance in the loss condition. These findings suggest that striatal responses during learning are abnormal in individuals with MDD but vary with the valence of information.
