Prevalence of Mental Health and Substance Use Difficulties Among Sexual and Gender Diverse Youth During COVID-19: A Systematic Review and Meta-Analysis.

Purpose: Sexual and gender diverse (SGD) youth have been particularly vulnerable to mental health difficulties and substance use during the COVID-19 pandemic. However, estimates have varied across studies pointing to the potential for moderator variables. This meta-analytic and narrative synthesis provides estimates of the prevalence of mental health difficulties (anxiety, depression, suicidal ideation, suicide attempts) and substance use during COVID-19 among SGD youth. Methods: A comprehensive search strategy combining keywords and subject headings was designed and used across seven databases from inception to October 7, 2022. The search yielded 826 nonduplicate records of which 191 full-text articles were retrieved, evaluated, and extracted by two study authors. Data were analyzed from February 27 to March 1, 2023. Results: Using random-effects meta-analyses, 19 studies from 18 independent samples with 10,500 participants were included. Pooled prevalence rates for clinically elevated anxiety, depression, and suicidal ideation were 55.4% [95% confidence interval (CI):45.9%-64.5%], 61.8% (95% CI: 50.9%-71.7%), and 50.9% (95% CI: 42.8%-59.0%). There was no evidence of publication bias. Suicide attempts and substance use were summarized narratively with rates of suicide attempts being greater than 20% across included studies and variable reporting of substance use across substance types. No moderators explained variability across studies. Conclusion: More than 50% of SGD youth experienced clinically elevated symptoms of anxiety, depression, and suicidal ideation during the COVID-19 pandemic, compared to prepandemic estimates for both SGD and non-SGD youth. Targeted resource allocation is needed to specifically address the needs of SGD youth.

Evaluating the use of the AMBIANCE-Brief measure in clinical settings: Assessing acceptability, feasibility, and utility of the AMBIANCE-Brief.

Community agencies and practitioners around the globe seek opportunities to learn various assessment tools and interventions rooted in attachment theory. However, information regarding the feasibility of implementation and sustainability of these tools once participants have been trained to use them, is limited. This study investigated the perceived acceptability, feasibility, utility, relevance, fidelity, and sustainability of the Atypical Maternal Behavior Instrument for Assessment and Classification-Brief (AMBIANCE-Brief) among practitioners who had taken a training. Practitioners (N = 59) who attended a virtual AMBIANCE-Brief training originating from Canada between June 2020 and November 2021 completed an online follow-up survey. Practitioners reported that they primarily used the AMBIANCE-Brief for case conceptualization (68%). Additionally, 95% agreed that the AMBIANCE-Brief was relevant to their clinical practice, 98% agreed it was useful for their clinical work, 76% agreed that it was feasible to implement into their clinical work, and 59% found it easy to incorporate into their treatment planning with clients. Findings suggest that the AMBIANCE-Brief may be acceptable, feasible, and useful for practitioners. Avenues for continuing to evaluate the AMBIANCE-Brief include cross-cultural validity, coder drift, and booster sessions. Additional work clarifying how practitioners integrate the measure into practice would be valuable.

Agencias comunitarias y profesionales de la práctica alrededor del mundo buscan oportunidades para aprender sobre varias herramientas de evaluación e intervenciones basadas en la teoría de la afectividad. Sin embargo, la información acerca de la posibilidad de implementación y sostenibilidad de estas herramientas, una vez que los participantes han sido entrenados para usarlas, es limitada. Este estudio investigó la percepción sobre la aceptabilidad, posibilidad, utilidad, relevancia, fidelidad y sostenibilidad del Instrumento de Comportamiento Materno Atípico para la Evaluación y Clasificación, versión abreviada (AMBIANCE­Abreviado) entre los profesionales de la práctica que habían recibido un entrenamiento. Los profesionales de la práctica (N = 59) que asistieron a un entrenamiento virtual de AMBIANCE­Abreviado que se originó en Canadá entre junio de 2020 y noviembre 2021, completaron en línea una encuesta de seguimiento. Los profesionales de la práctica reportaron que ellos primariamente usaban el AMBIANCE­Abreviado para el caso de conceptualización (68%). Adicionalmente, el 95% estuvo de acuerdo en que el AMBIANCE­Abreviado era relevante para su práctica clínica, 98% estuvo de acuerdo con que era útil para su trabajo clínico, 76% estuvo de acuerdo que era posible implementarlo en su trabajo clínico, y 59% lo encontraba fácil de incorporar en su plan de tratamiento con clientes. Los resultados sugieren que el AMBIANCE­Abreviado pudiera ser aceptable, posible y útil para los profesionales de la práctica. Entre las maneras para continuar evaluando el AMBIANCE­Abreviado se incluyen la validez intercultural, la variación del codificador y las sesiones de refuerzo. El trabajo adicional que clarifique cómo los profesionales integran la medida dentro de su práctica sería valioso.

Social factors associated with self-reported changes in mental health symptoms among youth in the COVID-19 pandemic: a cross-sectional survey.

BACKGROUND: Children and youth experienced marked impacts on day-to-day life in the COVID-19 pandemic that were associated with poorer familial and friend relationships, and greater mental health challenges. Few studies provide self-report data on mental health symptoms from children and youth themselves. We sought to examine the associations between social factors and child and youth self-reported symptoms of worsened mood, anxiety, and irritability during the COVID-19 pandemic. METHODS: A nationally representative cross-sectional survey was administered online to collect self-report data across 10 Canadian provinces among children (11-14 years) and youth (15-18 years), April-May 2022. Age-appropriate questions were based on The Partnership for Maternal, Newborn & Child Health and the World Health Organization of the United Nations H6 + Technical Working Group on Adolescent Health and Well-Being consensus framework and the Coronavirus Health and Impact Survey. Associations between a priori defined social factors (e.g., relationship quality) and respondent self-reported mental health were evaluated using ordinal logistic regression models adjusted for age, sex, and geographic location. RESULTS: We analyzed data from 483 (51.7%) children (11-14 years; 227, 47.0% girls) and 450 (48.3%) youth (15-18 years; 204, 45.3% girls). The parents of most children and youth had resided in Canada for over 20 years (678, 72.7%). Over one-quarter of children and youth self-identified as Black, Indigenous, or a Person of Color (134, 27.7%; 134, 29.8%, respectively). Over one-third of children and youth self-reported symptoms of worsened mood (149, 30.9%; 125, 27.8%, respectively), anxiety (181, 37.5%; 167, 37.1%, respectively), or irritability (160, 33.1%; 160, 35.6%, respectively) during, compared to pre-pandemic. In descending order of odds ratios (OR), for children and youth, worsened familial relationships (during compared to pre-pandemic) was associated with the self-reported symptoms of worsened mood (child: OR 4.22, 95%CI 2.51-6.88; youth: OR 6.65 95%CI 3.98-11.23), anxiety (child: OR 4.24, 95%CI2.69-6.75; youth: OR 5.28, 95%CI 3.17-8.86), and irritability (child: OR 2.83, 95%CI 1.76-4.56; youth: OR 6.46, 95%CI 3.88-10.90). CONCLUSIONS: Self-reported data from a nationally representative sample of children and youth suggest strong associations between social factors and mental health during the COVID-19 pandemic. Interventions targeting child and youth familial relationships may positively impact child and youth mental health.

A randomized waitlist control trial of the Make the Connection® online program for caregivers of infants and young children: Study protocol.

Background: A positive child-caregiver relationship is one of the strongest determinants of child health and development, yet many caregivers report challenges in establishing a positive relationship with their child. For over 20 years, Make the Connection® (MTC), an evidence-based parenting program, has been delivered in-person by child-caring professionals to over 120,000 parents to improve positive parenting behaviours and attitudes. Recently, MTC has been adapted into a 'direct to caregiver' online platform to increase scalability and accessibility. The purpose of this study is to evaluate the effectiveness of the online modality of MTC in increasing parenting knowledge, attitudes, and the perceived relationship with their child, and to understand barriers and facilitators to its access. Methods: Two hundred caregivers with children aged 0-3 years old will be recruited through Public Health agencies in Ontario, Canada. Participants will be randomly placed in the intervention or waitlist control group. Both groups will complete a battery of questionnaires at study enrolment and 8 weeks later. The intervention group will receive the MTC online program during the 8-week period, while the waitlist group will receive the program after an 8-week wait. The study questionnaires will address demographic information, caregivers' relational attitudes towards their infant, self-competence in their caregiver role, depression, and caregiver stress, as well as caregivers' and infants' emotion regulation. Discussion: Results from this study will add critical knowledge to the development, scaling, and roll out of the MTC online program, thus increasing its capacity to reach a greater number of families. Trial registration: The study was registered with ClinicalTrials.gov on 15 March 2023 (NCT05770414).

A comparative effectiveness study of the breaking the cycle and Maxxine Wright intervention programs for substance-involved mothers and their children: study protocol.

BACKGROUND: Children of substance-involved mothers are at especially high risk for exposure to adverse childhood experiences (ACEs) and poor mental health and development. Early interventions that support mothers, children, and the mother-child relationship have the greatest potential to reduce exposure to early adversity and the mental health problems associated with these exposures. Currently, there is a lack of evidence from the real-world setting demonstrating effectiveness and return on investment for intervention programs that focus on the mother-child relationship in children of substance-involved mothers. METHODS: One hundred substance-involved pregnant and/or parenting women with children between the ages of 0-6 years old will be recruited through the Breaking the Cycle and Maxxine Wright intervention programs, in Toronto, Ontario, Canada and Surrey, British Columbia, Canada, respectively. Children's socioemotional development and exposure to risk and protective factors, mothers' mental health and history of ACEs, and mother-child relationship quality will be assessed in both intervention programs. Assessments will occur at three time points: pre-intervention, 12-, and 24-months after engagement in the intervention program. DISCUSSION: There is a pressing need to identify interventions that promote the mental health of infants and young children exposed to early adversity. Bringing together an inter-disciplinary research team and community partners, this study aligns with national strategies to establish strong evidence for infant mental health interventions that reduce child exposure to ACEs and support the mother-child relationship. This study was registered with clinicaltrials.gov (NCT05768815) on March 14, 2023.

Maternal postnatal depressive symptoms and early achievement of developmental milestones in infants and young children: A meta-analysis.

Screening for social determinants of health, including maternal depression, is a recommended pediatric practice. However, the magnitude of association between maternal and child screening tools remains to be determined. The current study evaluated the association between maternal postnatal depressive symptoms and child developmental milestones, as well as moderators of these associations. A comprehensive search strategy was carried out in four databases (MEDLINE, EMBASE, APA PsycINFO, and Cochrane Central Register of Controlled Trials) from database inception to September 2022. Studies that examine postnatal depressive symptoms and associations with infant and early child (<6 years) achievement of developmental milestones were included. Data were extracted by two independent coders and a random-effects meta-analysis was used to estimate pooled effect sizes and test for moderators. A total of 38 non-overlapping studies (95,897 participants), all focused on maternal postnatal depression, met inclusion criteria. The pooled effect size for the association between postnatal depressive symptoms and early achievement of infant and child developmental milestones (N = 38; r = -.12; 95% CI = -.18, -.06) was small in magnitude. Child age at maternal depression measurement was a moderator, whereby effect sizes became greater for older children. Despite small effects, maternal postnatal depressive symptoms should be included in screening during routine well-child visits to enhance child development outcomes.

El examinar los determinantes sociales de la salud, incluyendo la depresión materna, es una práctica pediátrica recomendada. Sin embargo, la magnitud de la asociación entre las herramientas de examinación materna y del niño está por ser determinada. El presente estudio evaluó la asociación entre los síntomas depresivos postnatales maternos y los momentos cruciales en el desarrollo del niño, así como su papel de moderadores de estas asociaciones. Una estrategia de investigación comprensiva se llevó a cabo en cuatro bancos de datos (MEDLINE, EMBASE, APA PsycINFO, y el Registro Central Cochrane para Ensayos Controlados) desde el inicio del banco de datos hasta septiembre de 2022. Se incluyeron los estudios que examinan los síntomas depresivos postnatales y sus asociaciones con el alcance de logros de momentos cruciales del infante y del niño en su temprana niñez (<6 años). Se extrajeron los datos por medio de dos independientes codificadores y se usó un metaanálisis de efectos al azar para estimar los tamaños de efectos agrupados y examinarlos como moderadores. Un total de 38 estudios que no compartían la misma información (95,897 participantes), todos enfocados en la depresión materna postnatal, reunieron los criterios para ser incluidos. El tamaño de los efectos agrupados para la asociación entre los síntomas depresivos postnatales y el logro temprano de los momentos cruciales del infante y el niño (N = 38; r = -.12; 95% CI = -.18, -.06) fue pequeño en magnitud. La edad del niño en la medida de la depresión materna fue un moderador, por lo cual los tamaños de los efectos se hicieron mayores para los niños de mayor edad. A pesar de los pequeños efectos, los síntomas depresivos postnatales maternos deben ser incluidos en la examinación durante las visitas rutinarias de chequeos del bienestar del niño para mejorar los resultados del desarrollo del niño.

Le dépistage de déterminants sociaux de la santé, y compris la dépression maternelle, est une pratique pédiatrique recommandée. Cependant la magnitude du lien entre les outils de dépistage maternelle et de l'enfant reste indéterminée. Cette étude a évalué le lien entre les symptômes dépressifs postnatals maternels et les jalons du développement de l'enfant, ainsi que les modérateurs de ces liens. Une stratégie de recherche exhaustive a été adoptée pour quatre bases de données (MEDLINE, EMBASE, APA PsycINFO, et Cochrane Central Register of Controlled Trials) des débuts de la base de données jusqu'à septembre 2022. Les études examinant les symptômes dépressifs postnatals et les liens avec l'atteinte des jalons de développement du nourrisson et du petit enfant (<6 ans) ont été inclues. Les données ont été extraites par deux codeurs et une méta-analyse à effets aléatoires a été utilisée afin d'estimer les tailles et tests d'effet regroupées pour les modérateurs. Un total de 38 études ne se recoupant pas (95897 participantes), toutes focalisées sur la dépression maternelle postnatale, ont rempli les critères d'inclusion. La taille d'effet regroupé pour le lien entre les symptômes dépressifs postnatales et l'atteinte précoce des jalons de développement du nourrisson et de l'enfant (N = 38; r = -,12; 95% CI = -,18, -,06) était petite en magnitude. L'âge de l'enfant à la mesure de la dépression maternelle était un modérateur, où l'ampleur de l'effet était plus grande pour les enfants plus âgés. En dépit du peu d'ampleur les symptômes dépressifs postnatals maternels devraient être inclus dans le dépistage durant les visites de routine de santé de l'enfant afin d'améliorer les résultats sur le développement de l'enfant.

Developing non-response weights to account for attrition-related bias in a longitudinal pregnancy cohort.

BACKGROUND: Prospective cohorts may be vulnerable to bias due to attrition. Inverse probability weights have been proposed as a method to help mitigate this bias. The current study used the "All Our Families" longitudinal pregnancy cohort of 3351 maternal-infant pairs and aimed to develop inverse probability weights using logistic regression models to predict study continuation versus drop-out from baseline to the three-year data collection wave. METHODS: Two methods of variable selection took place. One method was a knowledge-based a priori variable selection approach, while the second used Least Absolute Shrinkage and Selection Operator (LASSO). The ability of each model to predict continuing participation through discrimination and calibration for both approaches were evaluated by examining area under the receiver operating curve (AUROC) and calibration plots, respectively. Stabilized inverse probability weights were generated using predicted probabilities. Weight performance was assessed using standardized differences of baseline characteristics for those who continue in study and those that do not, with and without weights (unadjusted estimates). RESULTS: The a priori and LASSO variable selection method prediction models had good and fair discrimination with AUROC of 0.69 (95% Confidence Interval [CI]: 0.67-0.71) and 0.73 (95% CI: 0.71-0.75), respectively. Calibration plots and non-significant Hosmer-Lemeshow Goodness of Fit Tests indicated that both the a priori (p = 0.329) and LASSO model (p = 0.242) were well-calibrated. Unweighted results indicated large (> 10%) standardized differences in 15 demographic variables (range: 11 - 29%), when comparing those who continued in the study with those that did not. Weights derived from the a priori and LASSO models reduced standardized differences relative to unadjusted estimates, with the largest differences of 13% and 5%, respectively. Additionally, when applying the same LASSO variable selection method to develop weights in future data collection waves, standardized differences remained below 10% for each demographic variable. CONCLUSION: The LASSO variable selection approach produced robust weights that addressed non-response bias more than the knowledge-driven approach. These weights can be applied to analyses across multiple longitudinal waves of data collection to reduce bias.

Enhancing attachment-based aspects of PCIT for young children with a history of maltreatment.

Disruptive behavior difficulties, such as aggression, non-compliance, and emotional outbursts, are common among children exposed to maltreatment. Parent-Child Interaction Therapy (PCIT) is an effective parenting intervention for addressing child behavior difficulties, however, treatment retention and engagement among parents remain a concern in the clinical setting. This paper describes how the delivery of an intervention that teaches attachment theory concepts (Circle of Security-Parenting, COS-P) prior to PCIT can increase engagement and retention among parents of maltreated children and inform new coaching practices. A detailed description of how to extend and integrate COS-P concepts with PCIT for maltreated families using specific strategies is provided. Recommendations, limitations, and next steps for research are presented.

Intergenerational transmission of parent adverse childhood experiences to child outcomes: A systematic review and meta-analysis.

OBJECTIVE: The current meta-analytic review provides a comprehensive synthesis of studies examining parent exposure to ACEs and the developmental and mental health outcomes of their children. PARTICIPANTS AND SETTING: Eligible studies up to August 2021 were identified through comprehensive database searches in PsycINFO, MEDLINE, and Embase. Studies that were included examined the intergenerational effects of parent ACEs on child development (i.e., cognitive, language, motor, social difficulties, and early social-emotional development) or mental health (i.e., internalizing problems, externalizing problems) outcomes. METHODS: Data were extracted by two coders using a standardized extraction protocol. A multi-level meta-analytic approach was used to derive pooled effect sizes and test for moderators. RESULTS: A total of 52 studies were included in the meta-analysis. Parent ACEs were positively associated with child mental health problems (r=0.17, 95% CI [0.12, 0.21], p<.001), child externalizing difficulties (r=0.20, 95% CI [0.15, 0.26], p<.001), and child internalizing difficulties (r=0.17, 95% CI [0.11, 0.22], p<.001). There were no significant sociodemographic (i.e., child age, parent age, income level, child sex, or racial/ethnic minority status) or methodological (i.e., study type or quality) moderators of these associations. Preliminary evidence suggests that parent ACEs were not associated with offspring developmental outcomes, such as cognitive or language skills. CONCLUSIONS: Results suggest that parent ACEs are associated with some, but not all child outcomes. Additional research focused on the mechanisms of transmission are needed to inform policies and practices related to the intergenerational transmission of ACEs.

Adverse childhood experiences: a meta-analysis of prevalence and moderators among half a million adults in 206 studies.

Exposure to adverse childhood experiences (ACEs), including maltreatment and family dysfunction, is a major contributor to the global burden of disease and disability. With a large body of international literature on ACEs having emerged over the past 25 years, it is timely to now synthetize the available evidence to estimate the global prevalence of ACEs and, through a series of moderator analyses, determine which populations are at higher risk. We searched studies published between January 1, 1998 and August 5, 2021 in Medline, PsycINFO and Embase. Study inclusion criteria were using the 8- or 10-item ACE Questionnaire (±2 items), reporting the prevalence of ACEs in population samples of adults, and being published in English. The review protocol was registered with PROSPERO (CRD42022348429). In total, 206 studies (208 sample estimates) from 22 countries, with 546,458 adult participants, were included. The pooled prevalence of the five levels of ACEs was: 39.9% (95% CI: 29.8-49.2) for no ACE; 22.4% (95% CI: 14.1-30.6) for one ACE; 13.0% (95% CI: 6.5-19.8) for two ACEs; 8.7% (95% CI: 3.4-14.5) for three ACEs, and 16.1% (95% CI: 8.9-23.5) for four or more ACEs. In subsequent moderation analyses, there was strong evidence that the prevalence of 4+ ACEs was higher in populations with a history of a mental health condition (47.5%; 95% CI: 34.4-60.7) and with substance abuse or addiction (55.2%; 95% CI: 45.5-64.8), as well as in individuals from low-income households (40.5%; 95% CI: 32.9-48.4) and unhoused individuals (59.7%; 95% CI: 56.8-62.4). There was also good evidence that the prevalence of 4+ ACEs was larger in minoritized racial/ethnic groups, particularly when comparing study estimates in populations identifying as Indigenous/Native American (40.8%; 95% CI: 23.1-59.8) to those identifying as White (12.1%; 95% CI: 10.2-14.2) and Asian (5.6%; 95% CI: 2.4-10.2). Thus, ACEs are common in the general population, but there are disparities in their prevalence. They are among the principal antecedent threats to individual well-being and, as such, constitute a pressing social issue globally. Both prevention strategies and downstream interventions are needed to reduce the prevalence and mitigate the severity of the effects of ACEs and thereby reduce their deleterious health consequences on future generations.

Associations between adverse childhood experiences and substance use: A meta-analysis.

BACKGROUND: Adverse childhood experiences (ACEs) can be associated with negative health outcomes such as substance use. However, extant literature assessing this association is mixed. OBJECTIVE: The present meta-analysis was conducted to obtain a pooled effect size for the association between ACEs and substance use (i.e., smoking, problematic alcohol use, heavy alcohol use, illicit drug use, and cannabis use). PARTICIPANTS AND SETTING: The present meta-analyses included 102 studies (N = 901,864), where 42.32 % of participants were male, and the mean age was 30.91 years. METHODS: Searches were conducted in MEDLINE, Embase, and PsycINFO in August 2021 and moderators were examined. Inclusion criteria included studies that measured ACEs prior to age 18 and substance use, and were published in English. All analyses were completed in Comprehensive Meta-Analysis Software, Version 3.0 (Borenstein et al., 2009). RESULTS: Pooled effect sizes between ACEs and smoking [OR = 1.803 (95 % CI 1.588, 2.048)], problematic alcohol use [OR = 1.812 (95 % CI 1.606, 2.044)], heavy alcohol use [OR = 1.537 (95 % CI 1.344, 1.758)], cannabis use [OR = 1.453 (95 % CI 1.184, 1.786)] and illicit drug use [OR = 1.695 (95 % CI 1.530, 1.878)] were significant. Significant moderators contribute to the understanding of the association between ACEs and substance use, and are discussed extensively. CONCLUSIONS: ACEs confer risk for substance use and trauma-informed approaches to substance use treatment should be considered. Study limitations and implications are discussed.

Non-pharmacological management of infant and young child procedural pain.

BACKGROUND: Despite evidence of the long-term implications of unrelieved pain during infancy, it is evident that infant pain is still under-managed and unmanaged. Inadequately managed pain in infancy, a period of exponential development, can have implications across the lifespan. Therefore, a comprehensive and systematic review of pain management strategies is integral to appropriate infant pain management. This is an update of a previously published review update in the Cochrane Database of Systematic Reviews (2015, Issue 12) of the same title. OBJECTIVES: To assess the efficacy and adverse events of non-pharmacological interventions for infant and child (aged up to three years) acute pain, excluding kangaroo care, sucrose, breastfeeding/breast milk, and music. SEARCH METHODS: For this update, we searched CENTRAL, MEDLINE-Ovid platform, EMBASE-OVID platform, PsycINFO-OVID platform, CINAHL-EBSCO platform and trial registration websites (ClinicalTrials.gov; International Clinical Trials Registry Platform) (March 2015 to October 2020). An update search was completed in July 2022, but studies identified at this point were added to 'Awaiting classification' for a future update.  We also searched reference lists and contacted researchers via electronic list-serves.  We incorporated 76 new studies into the review.  SELECTION CRITERIA: Participants included infants from birth to three years in randomised controlled trials (RCTs) or cross-over RCTs that had a no-treatment control comparison. Studies were eligible for inclusion in the analysis if they compared a non-pharmacological pain management strategy to a no-treatment control group (15 different strategies). In addition, we also analysed studies when the unique effect of adding a non-pharmacological pain management strategy onto another pain management strategy could be assessed (i.e. additive effects on a sweet solution, non-nutritive sucking, or swaddling) (three strategies). The eligible control groups for these additive studies were sweet solution only, non-nutritive sucking only, or swaddling only, respectively. Finally, we qualitatively described six interventions that met the eligibility criteria for inclusion in the review, but not in the analysis.  DATA COLLECTION AND ANALYSIS: The outcomes assessed in the review were pain response (reactivity and regulation) and adverse events. The level of certainty in the evidence and risk of bias were based on the Cochrane risk of bias tool and the GRADE approach. We analysed the standardised mean difference (SMD) using the generic inverse variance method to determine effect sizes.  MAIN RESULTS: We included total of 138 studies (11,058 participants), which includes an additional 76 new studies for this update. Of these 138 studies, we analysed 115 (9048 participants) and described 23 (2010 participants) qualitatively. We described qualitatively studies that could not be meta-analysed due to being the only studies in their category or statistical reporting issues. We report the results of the 138 included studies here. An SMD effect size of 0.2 represents a small effect, 0.5 a moderate effect, and 0.8 a large effect. The thresholds for the I2 interpretation were established as follows: not important (0% to 40%); moderate heterogeneity (30% to 60%); substantial heterogeneity (50% to 90%); considerable heterogeneity (75% to 100%). The most commonly studied acute procedures were heel sticks (63 studies) and needlestick procedures for the purposes of vaccines/vitamins (35 studies). We judged most studies to have high risk of bias (103 out of 138), with the most common methodological concerns relating to blinding of personnel and outcome assessors. Pain responses were examined during two separate pain phases: pain reactivity (within the first 30 seconds after the acutely painful stimulus) and immediate pain regulation (after the first 30 seconds following the acutely painful stimulus). We report below the strategies with the strongest evidence base for each age group. In preterm born neonates, non-nutritive sucking may reduce pain reactivity (SMD -0.57, 95% confidence interval (CI) -1.03 to -0.11, moderate effect; I2 = 93%, considerable heterogeneity) and improve immediate pain regulation (SMD -0.61, 95% CI -0.95 to -0.27, moderate effect; I2 = 81%, considerable heterogeneity), based on very low-certainty evidence. Facilitated tucking may also reduce pain reactivity (SMD -1.01, 95% CI -1.44 to -0.58, large effect; I2 = 93%, considerable heterogeneity) and improve immediate pain regulation (SMD -0.59, 95% CI -0.92 to -0.26, moderate effect; I2 = 87%, considerable heterogeneity); however, this is also based on very low-certainty evidence. While swaddling likely does not reduce pain reactivity in preterm neonates (SMD -0.60, 95% CI -1.23 to 0.04, no effect; I2 = 91%, considerable heterogeneity), it has been shown to possibly improve immediate pain regulation (SMD -1.21, 95% CI -2.05 to -0.38, large effect; I2 = 89%, considerable heterogeneity), based on very low-certainty evidence. In full-term born neonates, non-nutritive sucking may reduce pain reactivity (SMD -1.13, 95% CI -1.57 to -0.68, large effect; I2 = 82%, considerable heterogeneity) and improve immediate pain regulation (SMD -1.49, 95% CI -2.20 to -0.78, large effect; I2 = 92%, considerable heterogeneity), based on very low-certainty evidence.  In full-term born older infants, structured parent involvement was the intervention most studied. Results showed that this intervention has little to no effect in reducing pain reactivity (SMD -0.18, 95% CI -0.40 to 0.03, no effect; I2 = 46%, moderate heterogeneity) or improving immediate pain regulation (SMD -0.09, 95% CI -0.40 to 0.21, no effect; I2 = 74%, substantial heterogeneity), based on low- to moderate-certainty evidence. Of these five interventions most studied, only two studies observed adverse events, specifically vomiting (one preterm neonate) and desaturation (one full-term neonate hospitalised in the NICU) following the non-nutritive sucking intervention. The presence of considerable heterogeneity limited our confidence in the findings for certain analyses, as did the preponderance of evidence of very low to low certainty based on GRADE judgements. AUTHORS' CONCLUSIONS: Overall, non-nutritive sucking, facilitated tucking, and swaddling may reduce pain behaviours in preterm born neonates. Non-nutritive sucking may also reduce pain behaviours in full-term neonates. No interventions based on a substantial body of evidence showed promise in reducing pain behaviours in older infants. Most analyses were based on very low- or low-certainty grades of evidence and none were based on high-certainty evidence. Therefore, the lack of confidence in the evidence would require further research before we could draw a definitive conclusion.

Exposure to sexual content and problematic sexual behaviors in children and adolescents: A systematic review and meta-analysis.

BACKGROUND: Exposure to sexual content, such as online pornography or live sexual content, has been posited in the literature as a risk factor for problematic sexual behaviors (PSBs) in children and adolescents, and has been identified as an important avenue for research and intervention, particularly given the ubiquitous access to technology among children. OBJECTIVE: To examine the association between live/violent and non-violent sexual content exposure and PSB among children and adolescents. Objectives also include informing future research on sexual content exposure as a risk factor for PSB, and providing clinical recommendations related to prevention and intervention. PARTICIPANTS AND SETTING: Results are based on 16,200 participants (28.65 % female; Mage = 14.26; range = 4.74-17.92) and 27 studies conducted in North America, Europe, Asia, and Africa. METHODS: A systematic review was conducted of available literature published up to September 2021. Abstract and full-text review were conducted to assess whether studies met inclusion criteria. Random-effects meta-analyses were conducted on included studies. RESULTS: Significant associations were found between exposure to non-violent sexual content and likelihood of engaging in PSB (OR = 1.82; p < .001; 95 % CI: 1.50-2.21), and between exposure to violent/live sexual content and PSB (OR = 2.52; p < .001; 95 % CI: 1.75-3.61). Sex emerged as a moderator of the association between exposure to non-violent sexual content and PSB, such that the association was stronger in studies with a greater proportion of females. CONCLUSIONS: Results support the need for future research on risk factors and mechanisms implicated in PSB. Prevention and intervention programs for children with PSB and their families could benefit from incorporating education on sexual content exposure.

Codesigning a user-centred digital psychoeducational tool for youth mental well-being with families in Canada: study protocol for a sequential exploratory mixed methods study.

INTRODUCTION: On 11 March 2020, WHO declared the novel coronavirus (COVID-19) disease a global pandemic. Governments globally implemented physical distancing measures and closure of public institutions that resulted in varying implications to youth mental well-being (eg, social isolation, reduced extracurricular activities). These impacts may have detrimental short-term and long-term effects on youth mental well-being; care for youth with mental health disorders was already overstretched, underfunded and fragmented before the pandemic and youth are not often considered in mental health initiatives. There is a pressing need to partner with youth and families to target and improve youth mental well-being prior to the onset of a mental health disorder, as well as to conduct research on youth mental well-being needs related to pandemic recovery. Here we present a protocol for partnering with youth and families to codesign a user-centred digital tool for youth mental well-being. METHODS AND ANALYSIS: We will conduct a national research study to develop a catalogue of recommendations specific to supporting youth mental well-being, and a digital tool to support youth mental well-being through three phases of work: (1) expert consultation on data related to supporting youth mental well-being existing within our Pandemic Preparedness Research Program; (2) codesign of an innovative digital tool for youth mental well-being; and (3) assessment of the tool's usability and acceptability. ETHICS AND DISSEMINATION: This study has been approved by the Dalhousie Research Ethics Board (2023-6538) and the Conjoint Health Research Ethics Board (23-0039). This study will complement ongoing foundational research in youth conducted by our team that involves partnering with youth and families to understand the unique implications of the pandemic on this population.

Changes and predictors of maternal depressive and anxiety symptoms during the COVID-19 pandemic.

Longitudinal changes in maternal depressive and anxiety symptoms and predictors of symptom variation among a group of middle-to-upper income Canadian women (n = 2152) were examined prior to the pandemic (2017-2019) and at three pandemic timepoints (May-July 2020, March-April 2021, November-December 2021). Mean maternal depression and anxiety scores were elevated throughout the pandemic. Pre-pandemic depressive symptoms were associated with greater increases in depressive symptoms. Coping and relationship quality were protective factors. Supporting the development of coping strategies may mitigate mental health concerns among mothers.

A muti-informant national survey on the impact of COVID-19 on mental health symptoms of parent-child dyads in Canada.

The COVID-19 pandemic negatively impacted the mental health of children, youth, and their families which must be addressed and prevented in future public health crises. Our objective was to measure how self-reported mental health symptoms of children/youth and their parents evolved during COVID-19 and to identify associated factors for children/youth and their parents including sources accessed for information on mental health. We conducted a nationally representative, multi-informant cross-sectional survey administered online to collect data from April to May 2022 across 10 Canadian provinces among dyads of children (11-14 years) or youth (15-18 years) and a parent (> 18 years). Self-report questions on mental health were based on The Partnership for Maternal, Newborn & Child Health and the World Health Organization of the United Nations H6+ Technical Working Group on Adolescent Health and Well-Being consensus framework and the Coronavirus Health and Impact Survey. McNemar's test and the test of homogeneity of stratum effects were used to assess differences between children-parent and youth-parent dyads, and interaction by stratification factors, respectively. Among 933 dyads (N = 1866), 349 (37.4%) parents were aged 35-44 years and 485 (52.0%) parents were women; 227 (47.0%) children and 204 (45.3%) youth were girls; 174 (18.6%) dyads had resided in Canada < 10 years. Anxiety and irritability were reported most frequently among child (44, 9.1%; 37, 7.7%) and parent (82, 17.0%; 67, 13.9%) dyads, as well as among youth (44, 9.8%; 35, 7.8%) and parent (68, 15.1%; 49, 10.9%) dyads; children and youth were significantly less likely to report worsened anxiety (p < 0.001, p = 0.006, respectively) or inattention (p < 0.001, p = 0.028, respectively) compared to parents. Dyads who reported financial or housing instability or identified as living with a disability more frequently reported worsened mental health. Children (96, 57.1%), youth (113, 62.5%), and their parents (253, 62.5%; 239, 62.6%, respectively) most frequently accessed the internet for mental health information. This cross-national survey contextualizes pandemic-related changes to self-reported mental health symptoms of children, youth, and families.
