RESUMO

BACKGROUND: Cognitive-behavioral therapy (CBT) and serotonin reuptake inhibitors (SRIs) are recommended treatments for pediatric obsessive-compulsive disorder (OCD), but their relative efficacy and acceptability have not been comprehensively examined. Further, it remains unclear whether the efficacy of in-person CBT is conserved when delivered in other formats, such as over telephone/webcam or as Internet-delivered CBT (ICBT). METHODS: PubMed, PsycINFO, trial registries, and previous systematic reviews were searched for randomized controlled trials (RCTs) comparing CBT (in-person, webcam/telephone-delivered, or ICBT) or SRIs with control conditions or each other. Network meta-analyses were conducted to examine efficacy (post-treatment Children's Yale-Brown Obsessive Compulsive Scale) and acceptability (treatment discontinuation). Confidence in effect estimates was evaluated with CINeMA (Confidence in Network Meta-Analysis). RESULTS: Thirty eligible RCTs and 35 contrasts comprising 2,057 youth with OCD were identified. In-person CBT was significantly more efficacious than ICBT, waitlist, relaxation training, and pill placebo (MD range: 3.95-11.10; CINeMA estimate of confidence: moderate) but did not differ significantly from CBT delivered via webcam/telephone (MD: 0.85 [-2.51, 4.21]; moderate), SRIs (MD: 3.07 [-0.07, 6.20]; low), or the combination of in-person CBT and SRIs (MD: -1.20 [-5.29, 2.91]; low). SRIs were significantly more efficacious than pill placebo (MD: 4.59 [2.70, 6.48]; low) and waitlist (MD: 8.03 [4.24, 11.82]; moderate). No significant differences for acceptability emerged, but confidence in estimates was low. CONCLUSIONS: In-person CBT and SRIs produce clear benefits compared to waitlist and pill placebo and should be integral parts of the clinical management of pediatric OCD, with in-person CBT overall having a stronger evidence base. The combination of in-person CBT and SRIs may be most efficacious, but few studies hinder firm conclusions. The efficacy of CBT appears conserved when delivered via webcam/telephone, while more trials evaluating ICBT are needed.

RESUMO

BACKGROUND: Ambulatory impairment is a common and complex manifestation of multiple sclerosis (MS), and longitudinal patterns are not well understood. OBJECTIVE: To characterize longitudinal walking speed trajectories in a general MS patient population and in those with early disease (⩽ 5 years from onset), identify subgroups with similar patterns, and examine associations with individual attributes. METHODS: Using a retrospective cohort study design, latent class growth analysis was applied to longitudinal timed 25-foot walk (T25-FW) data from 7683 MS patients, to determine T25-FW trajectories. Associations were evaluated between trajectory assignment and individual attributes. Analyses were repeated for 2591 patients with early disease. RESULTS: In the general patient population, six trajectories were discerned, ranging from very minimal to very high impairment at baseline, with variability in impairment accrual. The clusters with moderate to very high walking impairment were associated with being female, older and Black American, longer symptom duration, progressive course, and depressive symptoms. In the early disease subset, eight trajectories were discerned that included two subgroups that rapidly accrued impairment. CONCLUSION: We identified novel subgroups of MS patients will distinct long-term T25-FW trajectories. These results underscore that socially disadvantaged and economically marginalized MS patients are the most vulnerable for severe ambulatory impairment.

RESUMO

Neuroimaging has played an important part in advancing our understanding of the neurobiology of obsessive-compulsive disorder (OCD). At the same time, neuroimaging studies of OCD have had notable limitations, including reliance on relatively small samples. International collaborative efforts to increase statistical power by combining samples from across sites have been bolstered by the ENIGMA consortium; this provides specific technical expertise for conducting multi-site analyses, as well as access to a collaborative community of neuroimaging scientists. In this article, we outline the background to, development of, and initial findings from ENIGMA's OCD working group, which currently consists of 47 samples from 34 institutes in 15 countries on 5 continents, with a total sample of 2,323 OCD patients and 2,325 healthy controls. Initial work has focused on studies of cortical thickness and subcortical volumes, structural connectivity, and brain lateralization in children, adolescents and adults with OCD, also including the study on the commonalities and distinctions across different neurodevelopment disorders. Additional work is ongoing, employing machine learning techniques. Findings to date have contributed to the development of neurobiological models of OCD, have provided an important model of global scientific collaboration, and have had a number of clinical implications. Importantly, our work has shed new light on questions about whether structural and functional alterations found in OCD reflect neurodevelopmental changes, effects of the disease process, or medication impacts. We conclude with a summary of ongoing work by ENIGMA-OCD, and a consideration of future directions for neuroimaging research on OCD within and beyond ENIGMA.

RESUMO

PURPOSE: To overcome the problems associated with existing measures of orthorexia, we assessed the reliability and validity of a new measure: the Orthorexia Nervosa Inventory (ONI). METHOD: An online survey was completed by 847 people recruited from undergraduate nutrition and psychology courses and from advertisements in Facebook and Instagram targeting both healthy eaters (with keywords such as "clean eating" and "healthy eating") and normal eaters (with keywords such as "delicious food" and "desserts"). RESULTS: Exploratory factor analysis revealed three factors with 9 items assessing behaviors and preoccupation with healthy eating, 10 items assessing physical and psychosocial impairments, and 5 items assessing emotional distress. With this sample, all scales demonstrated good internal consistency (Cronbach's α = 0.88-0.90) and 2-week test-retest reliability (r = 0.86- 0.87). Consistent with past research, ONI scores were significantly greater among vegetarians and vegans, and among those with higher levels of disordered eating, general obsessive-compulsive tendencies, and compulsive exercise. Additionally, whereas ONI scores did not significantly differ between men and women, the scores were negatively correlated with body mass index. CONCLUSION: The ONI is the first orthorexia measure to include items assessing physical impairments that researchers and clinicians agree comprise a key component of the disorder. Additionally, at least for the current sample, the ONI is a reliable measure with expected correlations based on the past research. LEVEL OF EVIDENCE: Level V, descriptive cross-sectional study.

RESUMO

Anxiety is a common and impairing condition in youth with autism spectrum disorders (ASD). Evidence supports the use of cognitive behavioral therapy for treating anxiety in this population; however, available treatment protocols may be difficult to implement outside of research settings. The present study examined the efficacy of family-based exposure-focused treatment (FET) compared to a treatment as usual (TAU) control in 32 youth aged 6-17 years with ASD and co-occurring anxiety. Fourteen youth were randomized to FET, which included 12 face-to-face weekly therapy sessions lasing 45-55 min, while 18 youth completed the TAU control where engagement in psychotherapy or pharmacotherapy was at the discretion of the families. Results strongly supported FET with a 79% (versus 0% in TAU) response rate, 86% (versus 0% in TAU) remission in primary anxiety diagnosis, and large between-group effects on clinician-rated anxiety severity and most parent-rated domains of anxiety-related impairment. Among treatment responders, 2-month follow-up supported maintenance of gains. Overall, the study supported FET as a relatively brief intervention for the treatment of anxiety in youth with ASD, although further research is needed to replicate these findings and compare FET outcomes to more comprehensive interventions.

RESUMO

OBJECTIVES: Length of stay (LOS) and boarding for pediatric psychiatric patients presenting in the emergency department (ED) have been understudied, despite evidence that children with psychiatric disorders experience longer LOS relative to those without. This investigation examined correlates of LOS and boarding among youth with psychiatric disorders presenting to the ED in a large, statewide database. METHODS: Using the 2010 to 2013 Florida ED discharge database, generalized linear mixed models were used to examine for associations between LOS and patient and hospital characteristics among pediatric patients (<18 years) who presented with a primary psychiatric diagnosis (N = 44,328). RESULTS: Patients had an overall mean ± SD ED LOS of 5.96 ± 8.64 hours. Depending on the definition used (ie, 12 or 6 hours), between 23% and 58% of transferred patients were boarded. Patient characteristics associated with a longer LOS included female sex, being 15 to 17 years old, Hispanic ethnicity, having Medicaid or VA/TriCare insurance, having impulse control problems, having mood or psychotic disorders, and exhibiting self-harm behaviors. Patient transfer, large hospital size, and rural designation were associated with longer LOS. Teaching hospital status and profit status were not significantly associated with LOS. CONCLUSIONS: These data suggest that LOS for pediatric psychiatry patients in the ED varies significantly by psychiatric presentation, patient disposition, and hospital factors. Such findings have implications for quality of care, patient safety, and health outcomes.

RESUMO

The present study examined concordance between the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) and its self-report version (Y-BOCS-SR), as well as theoretically derived moderators. Sixty-seven adults (ages 18-67) with obsessive-compulsive disorder (OCD) were administered the Y-BOCS prior to completing self-report measures. The Y-BOCS-SR generated lower scores relative to the clinician-administered Y-BOCS (5.3 points lower). Strong correspondence was shown between the Y-BOCS and Y-BOCS-SR; however, many items exhibited fair to moderate agreement, particularly the resistance and control against obsessions/compulsions items. Depression significantly moderated correspondence such that Y-BOCS-SR scores significantly predicted Y-BOCS scores in the presence of low and average depression levels in our sample, but not for patients with high levels of depression relative to the rest of our sample; gender, generalized anxiety and obsessionality did not significantly impact agreement. Synthesizing the present data, the Y-BOCS-SR demonstrates modest agreement with the Y-BOCS and may underestimate clinical severity especially for those with high levels of depression.

RESUMO

The objective of the study was to examine the optimal Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) percent reduction and raw cutoffs for predicting cognitive-behavioral treatment (CBT) response among children and adolescents with obsessive-compulsive disorder (OCD). The sample consisted of children and adolescents with OCD (N = 241) participating in the first step of the Nordic long-term OCD treatment study and receiving 14 weekly sessions of CBT in the form of exposure and response prevention. Evaluations were conducted pre- and post-treatment, included the CY-BOCS, Clinical Global Impressions-severity/improvement. The results showed that the most efficient CY-BOCS cutoffs were 35 % reduction for treatment response, 55 % reduction for remission, and a post-treatment CY-BOCS raw total score of 11 for treatment remission. Overall, our results diverge from previous research on pediatric OCD with more conservative cutoffs (higher cutoff reduction for response and remission, and lower raw score for remission). Further research on optimal cutoffs is needed.

RESUMO

This study evaluated the psychometric properties of the Child Disgust Scale (CDS) among 457 youth (ages 8-17, M = 14.77 ± 1.98 years) initiating residential treatment for obsessive-compulsive disorder and anxiety disorders. Confirmatory factor analysis supported a bifactor model with two distinct factors of Disgust Avoidance and Disgust Affect, in addition to an overall General Disgust factor. Strong internal consistency was observed for the CDS total and factor scores. In addition, CDS scores demonstrated generally modest and positive correlations with child-reported obsessive-compulsive and anxiety symptoms, weaker correlations with parent-reported anxiety and child-rated impairment, and non-significant correlations with parent-rated impairment. Findings suggest that the CDS displays strong psychometric properties and is developmentally appropriate for use in pediatric clinical populations with obsessive-compulsive and anxiety disorders.

RESUMO

The present study examined differences in symptom presentation in screening for pediatric depression via evaluation of the Patient Health Questionnaire-9 (PHQ-9). In particular, we examined whether PHQ-9 items function differentially among deaf and hard-of-hearing (DHH; n = 75) and hearing (n = 75) youth based on participants recruited from crisis assessment services. Multiple indicators multiple causes models were used to examine whether items of the PHQ-9 functioned differently between groups as well as whether there were group differences in the mean severity of depressive symptoms. Results indicate that DHH youth were more likely to endorse psychosomatic items, and less likely to endorse an affective item. These findings indicate that the PHQ-9 functions differently when used with DHH youth. Implications of these findings are discussed, including both for future work with the PHQ-9 and with regard to the conceptualization of depression across hearing groups.

RESUMO

OBJECTIVE: Examine the efficacy of a personalized, modular cognitive-behavioral therapy (CBT) protocol among early adolescents with high-functioning autism spectrum disorders (ASDs) and co-occurring anxiety relative to treatment as usual (TAU). METHOD: Thirty-one children (11-16 years) with ASD and clinically significant anxiety were randomly assigned to receive 16 weekly CBT sessions or an equivalent duration of TAU. Participants were assessed by blinded raters at screening, posttreatment, and 1-month follow-up. RESULTS: Youth randomized to CBT demonstrated superior improvement across primary outcomes relative to those receiving TAU. Eleven of 16 adolescents randomized to CBT were treatment responders, versus 4 of 15 in the TAU condition. Gains were maintained at 1-month follow-up for CBT responders. CONCLUSIONS: These data extend findings of the promising effects of CBT in anxious youth with ASD to early adolescents.

RESUMO

OBJECTIVE: The Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) is the most commonly used instrument to assess the clinical severity of obsessive-compulsive symptoms. Treatment determinations are often based on Y-BOCS score thresholds. However, these benchmarks are not empirically based, which may result in non-evidence based treatment decisions. Accordingly, the present study sought to derive empirically-based benchmarks for defining obsessive-compulsive symptom severity. METHOD: Nine hundred fifty-four adult patients with obsessive-compulsive disorder (OCD), recruited through the Brazilian Research Consortium on Obsessive-Compulsive Spectrum Disorders, were evaluated by experienced clinicians using a structured clinical interview, the Y-BOCS, and the Clinical Global Impressions-Severity scale (CGI-Severity). RESULTS: Similar to results in treatment-seeking children with OCD, our findings demonstrated convergence between the Y-BOCS and global OCD severity assessed by the CGI-Severity (Nagelkerke R(2)=.48). Y-BOCS scores of 0-13 corresponded with 'mild symptoms' (CGI-Severity=0-2), 14-25 with 'moderate symptoms' (CGI-Severity=3), 26-34 with 'moderate-severe symptoms' (CGI-Severity=4) and 35-40 with 'severe symptoms' (CGI-Severity=5-6). Neither age nor ethnicity was associated with Y-BOCS scores, but females demonstrated more severe obsessive-compulsive symptoms than males (d=.34). Time spent on obsessions/compulsions, interference, distress, resistance, and control were significantly related to global OCD severity although the symptom resistance item pairing demonstrated a less robust relationship relative to other components of the Y-BOCS. CONCLUSIONS: These data provide empirically-based benchmarks on the Y-BOCS for defining the clinical severity of treatment seeking adults with OCD, which can be used for normative comparisons in the clinic and for future research.

RESUMO

Obsessive-compulsive disorder (OCD) is marked by the presence of obsessions and/or compulsions that cause significant interference in an individual's life. Insight regarding symptoms in youth with OCD may affect accurate assessment, acceptance and motivation for treatment, tolerance of negative valence states (i.e., fear) and treatment outcome, so assessment of this construct and associated clinical characteristics is important. Accordingly, the current study sought to expand the literature on symptom insight by examining multi-informant ratings of insight from children, parents, and clinicians simultaneously and its relationship to varied clinical characteristics. One-hundred and ten treatment-seeking youth with a primary diagnosis of OCD, aged 6-17, participated in the study along with a parent/guardian. The nature of symptom conviction, fixity of ideas, and perceptions about the cause of the problems were important indicators in assessing child insight and resulted in a comprehensive, psychometrically-sound measure of insight. Insight was generally not strongly associated with clinical characteristics. Poor insight was moderately associated with less resistance of obsessive-compulsive symptoms, increased externalizing symptoms, and ordering symptoms. Overall, this study contributes further information into the nature and correlates of insight in youth with OCD, and provides a psychometrically sound approach for its assessment.

RESUMO

The psychometric properties of the Obsessive Compulsive Inventory-Child Version (OCI-CV) were examined in ninety-six youth with a primary/co-primary diagnosis of obsessive-compulsive disorder (OCD). A confirmatory factor analysis revealed an acceptable model of fit with factors consisting of doubting/checking, obsessing, hoarding, washing, ordering, and neutralizing. The internal consistency of the OCI-CV total score was good, while internal consistency for subscale scores ranged from poor to good. The OCI-CV was modestly correlated with obsessive-compulsive symptom severity on the Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS) Severity Scale, as well as with clinician-reported OCD severity. All OCI-CV subscales significantly correlated with the corresponding CY-BOCS Symptom Checklist dimension. The OCI-CV significantly correlated with child-reported depressive symptoms and OCD-related functional impairment, but was not significantly correlated with parent-reported irritability or clinician-reported overall functioning. Taken together, these data suggest the psychometric properties of the OCI-CV are adequate for assessing obsessive-compulsive symptom presence among youth with OCD.

RESUMO

OBJECTIVE: A growing body of research has emerged to characterize differences in posttraumatic stress disorder (PTSD) symptom presentations in individuals from diverse racial and ethnic groups. However, less research has examined if these observed differences can be attributed to bias within PTSD assessments. Knowledge about potential bias in PTSD assessment is essential for interpreting group differences. If PTSD assessments do not perform similarly across diverse demographic groups, then observed differences may be artificial products of inaccurate measurement, new assessments could be required for individuals from different demographic groups, and we would be unable to accurately detect PTSD treatment effects in patients from diverse groups. METHOD: We evaluated PTSD assessment bias through tests of measurement invariance for the semistructured, clinician-administered AUDADIS-5 diagnostic assessment of participants in the National Epidemiologic Survey on Alcohol and Related Conditions-III. Participants included those who reported having experienced at least one potentially traumatic event in their lifetime (N = 23,936). Measurement invariance was assessed for participants who identified from several demographic groups (Asian, Native Hawaiian, or Pacific Islander; Hispanic; American Indian/Alaskan Native; and Black) compared to participants who identified as White (non-Hispanic). RESULTS: Overall, PTSD assessment was largely invariant across groups, while small amounts of measurement invariance were detected that can inform future research and clinical adaptations. CONCLUSIONS: This work validates prior research that relies on a common conceptualization of PTSD, and it provides several paths for future improvement in research and clinical practice.

RESUMO

BACKGROUND AND OBJECTIVES: Reasons for compulsive hair pulling are heterogeneous and not fully understood. Given that many people who experience compulsive hair pulling do not respond to treatment, identifying subgroups can inform potential mechanisms and treatment design. METHODS: We sought to identify empirical subgroups among participants in an online treatment program for trichotillomania (N = 1728). A latent class analysis was used to identify patterns of emotions associated with compulsive hair-pulling episodes. RESULTS: Six classes of participants were found which reflected three predominant themes. One theme reflected expected patterns, where emotional changes were seen following pulling. Two other themes were more surprising, where one reflected high overall emotional activation that did not show consistent change in response to pulling, and another showed low emotional activation overall. These results suggest that there are multiple types of hair-pulling and a sizeable group of people may benefit from treatment adjustments. LIMITATIONS: Participants did not receive semi-structured diagnostic assessment. A majority of participants were Caucasian, and future research would benefit from increased participant diversity. Emotions associated with compulsive hair-pulling were measured across an entire treatment program, but the relationship between specific intervention components and change in specific emotions was not systematically collected. CONCLUSIONS: While previous research has addressed overall phenomenology and comorbidity, the present study is the first to identify empirical subgroups of people who experience compulsive hair-pulling at the level of individual pulling episodes. Identified participant classes had distinguishing features that can aid in personalizing treatment to individual symptom presentations.

RESUMO

While much research has highlighted phenotypic heterogeneity in obsessive compulsive disorder (OCD), less work has focused on heterogeneity in neural activity. Conventional neuroimaging approaches rely on group averages that assume homogenous patient populations. If subgroups are present, these approaches can increase variability and can lead to discrepancies in the literature. They can also obscure differences between various subgroups. To address this issue, we used unsupervised machine learning to identify subgroup clusters of patients with OCD who were assessed by task-based fMRI. We predominantly focused on activation of cognitive control and performance monitoring neurocircuits, including three large-scale brain networks that have been implicated in OCD (the frontoparietal network, cingulo-opercular network, and default mode network). Participants were patients with OCD (n = 128) that included both adults (ages 24-45) and adolescents (ages 12-17), as well as unaffected controls (n = 64). Neural assessments included tests of cognitive interference and error processing. We found three patient clusters, reflecting a "normative" cluster that shared a brain activation pattern with unaffected controls (65.9% of clinical participants), as well as an "interference hyperactivity" cluster (15.2% of clinical participants) and an "error hyperactivity" cluster (18.9% of clinical participants). We also related these clusters to demographic and clinical correlates. After post-hoc correction for false discovery rates, the interference hyperactivity cluster showed significantly longer reaction times than the other patient clusters, but no other between-cluster differences in covariates were detected. These findings increase precision in patient characterization, reframe prior neurobehavioral research in OCD, and provide a starting point for neuroimaging-guided treatment selection.

RESUMO

OBJECTIVE: Movement disorders are chronic illnesses that can lead to functional impairment and psychological distress. This study examined the relations between functional impairment, depression, and anxiety in individuals with movement disorders, and whether these associations were mediated by feelings of self-perceived burden. METHOD: This cross-sectional study sampled individuals (57 males and 57 females; mean age of 62) with chronic movement disorders from a movement disorders clinic. Patients completed measures of depression, anxiety, functional impairment, and self-perceived burden. RESULTS: Functional impairment was associated with depression, but not anxiety, and was mediated by self-perceived burden for individuals with chronic movement disorders. CONCLUSIONS: Self-perceived burden may have an important role relative to individuals' adaptation to chronic illness with implications for future interventions.

RESUMO

This paper presents the psychometric evaluation of brief measures of therapeutic alliance (TA) for youths, clinicians and caregivers and a longitudinal analysis of relationships between changes in TA and changes in youth symptom and functioning severity. Psychometric analyses using methods from Classical Test Theory, Item Response Theory, and Factor Analysis indicate that the measures of TA used in this study offer something new for both practice and research. The measures have variability, sensitivity to change over time, brevity and can be used with multiple parties through parallel forms. The longitudinal analyses, employing hierarchical linear modeling with time-varying covariates, found that TA ratings of the clinician correlated with symptom improvement as rated by the clinician, caregiver and youth. Additional analyses showed that decreases in clinician-rated youth TA was most important in predicting a lower rate of youth improvement. Implications for future research and clinical practice are discussed.

RESUMO

Obsessive-compulsive disorder (OCD) is highly heterogeneous. Although perseverative negative thinking (PT) is a feature of OCD, little is known about its neural mechanisms or relationship to clinical heterogeneity in the disorder. In a sample of 85 OCD patients, we investigated the relationships between self-reported PT, clinical symptom subtypes, and resting-state functional connectivity measures of local and global connectivity. Results indicated that PT scores were highly variable within the OCD sample, with greater PT relating to higher severity of the "unacceptable thoughts" symptom dimension. PT was positively related to local connectivity in subgenual anterior cingulate cortex (ACC), pregenual ACC, and the temporal poles-areas that are part of, or closely linked to, the default mode network (DMN)-and negatively related to local connectivity in sensorimotor cortex. While the majority of patients showed higher local connectivity strengths in sensorimotor compared to DMN regions, OCD patients with higher PT scores had less of an imbalance between sensorimotor and DMN connectivity than those with lower PT scores, with healthy controls exhibiting an intermediate pattern. Clinically, this imbalance was related to both the "unacceptable thoughts" and "symmetry/not-just-right-experiences" symptom dimensions, but in opposite directions. These effects remained significant after accounting for variance related to psychiatric comorbidity and medication use in the OCD sample, and no significant relationships were found between PT and global connectivity. These data indicate that PT is related to symptom and neural variability in OCD. Future work may wish to target this circuity when developing personalized interventions for patients with these symptoms.
