Effectiveness of nurse-home visiting in improving child and maternal outcomes prenatally to age two years: a randomised controlled trial (British Columbia Healthy Connections Project).

BACKGROUND: We investigated the effectiveness of Nurse-Family Partnership (NFP), a prenatal-to-age-two-years home-visiting programme, in British Columbia (BC), Canada. METHODS: For this randomised controlled trial, we recruited participants from 26 public health settings who were: <25 years, nulliparous, <28 weeks gestation and experiencing socioeconomic disadvantage. We randomly allocated participants (one-to-one; computer-generated) to intervention (NFP plus existing services) or comparison (existing services) groups. Prespecified outcomes were prenatal substance exposure (reported previously); child injuries (primary), language, cognition and mental health (problem behaviour) by age two years; and subsequent pregnancies by 24 months postpartum. Research interviewers were masked. We used intention-to-treat analyses. (ClinicalTrials.gov, NCT01672060.) RESULTS: From 2013 to 2016 we enrolled 739 participants (368 NFP, 371 comparison) who had 737 children. Counts for child injury healthcare encounters [rate per 1,000 person-years or RPY] were similar for NFP (223 [RPY 316.17]) and comparison (223 [RPY 305.43]; rate difference 10.74, 95% CI -46.96, 68.44; rate ratio 1.03, 95% CI 0.78, 1.38). Maternal-reported language scores (mean, M [SD]) were statistically significantly higher for NFP (313.46 [195.96]) than comparison (282.77 [188.15]; mean difference [MD] 31.33, 95% CI 0.96, 61.71). Maternal-reported problem-behaviour scores (M [SD]) were statistically significantly lower for NFP (52.18 [9.19]) than comparison (54.42 [9.02]; MD -2.19, 95% CI -3.62, -0.75). Subsequent pregnancy counts were similar (NFP 115 [RPY 230.69] and comparison 117 [RPY 227.29]; rate difference 3.40, 95% CI -55.54, 62.34; hazard ratio 1.01, 95% CI 0.79, 1.29). We observed no unanticipated adverse events. CONCLUSIONS: NFP did not reduce child injuries or subsequent maternal pregnancies but did improve maternal-reported child language and mental health (problem behaviour) at age two years. Follow-up of long-term outcomes is warranted given that further benefits may emerge across childhood and adolescence.

Savoir détecter l'exposition des enfants à la violence entre partenaires intimes, qu'elle soit présumée ou divulguée, et savoir intervenir.

L'exposition des enfants à la violence entre partenaires intimes (EEVPI), qu'il s'agisse des parents ou d'autres proches, représente près de la moitié de tous les cas qui font l'objet d'une enquête et sont corroborés par les services de protection de l'enfance du Canada. Les atteintes affectives, physiques et comportementales associées à l'EEVPI sont semblables aux effets d'autres formes de maltraitance envers les enfants. Il peut être difficile d'établir quels enfants et adolescents sont exposés à la violence entre partenaires intimes (VPI) en raison des comportements non spécifiques parfois associés à une telle exposition, de même que de la stigmatisation et du secret entourant souvent ce type de violence. Par ailleurs, une intervention en toute sécurité auprès des enfants et des adolescents chez qui on présume une exposition à la VPI peut être compliquée par la nécessité d'également tenir compte de la sécurité et du bien-être d'un proche non contrevenant. Le présent document de principes propose une approche fondée sur des données probantes mise au point par le projet VEGA (Violence, Evidence, Guidance, Action ou violence, données probantes, conseils, action) pour détecter l'exposition des enfants et des adolescents à la VPI et intervenir en toute sécurité auprès d'eux.

Recognizing and responding to children with suspected exposure to intimate partner violence between caregivers.

Children's exposure to intimate partner violence (CEIPV) between parents and other caregivers accounts for nearly half of all cases investigated and substantiated by child welfare authorities in Canada. The emotional, physical, and behavioural impairments associated with CEIPV are similar to effects of other forms of child maltreatment. The identification of children and youth who have been exposed to intimate partner violence (IPV) can be challenging due to the non-specific behaviours sometimes associated with such exposure, and the stigma and secrecy that often characterize IPV. Also, responding safely to children and youth with suspected CEIPV can be complicated by the need to consider the safety and well-being of a non-offending caregiver. This position statement presents an evidence-informed approach developed by the Violence, Evidence, Guidance, Action (VEGA) Project for the safe recognition and response to children and youth who are suspected of being exposed to IPV.

Social engagement and allostatic load mediate between adverse childhood experiences and multimorbidity in mid to late adulthood: the Canadian Longitudinal Study on Aging.

BACKGROUND: Adverse childhood experiences (ACEs) are associated with multimorbidity in adulthood. This link may be mediated by psychosocial and biological factors, but evidence is lacking. The current study evaluates this mediation model. METHOD: We analyzed data from the Canadian Longitudinal Study of Aging (N = 27 170 community participants). Participants were 45-85 years at recruitment, when allostatic load and social engagement data were collected, and 3 years older at follow-up, when ACEs and multimorbidity data were collected. Structural equation modeling was used to test for mediation in the overall sample, and in sex- and age-stratified subsamples, all analyses adjusted for concurrent lifestyle confounds. RESULTS: In the overall sample, ACEs were associated with multimorbidity, directly, ß = 0.12 (95% confidence interval 0.11-0.13) and indirectly. Regarding indirect associations, ACEs were related to social engagement, ß = -0.14 (-0.16 to -0.12) and social engagement was related to multimorbidity, ß = -0.10 (-0.12 to -0.08). ACEs were related to allostatic load, ß = 0.04 (0.03-0.05) and allostatic load was related to multimorbidity, ß = 0.16 (0.15-0.17). The model was significant for males and females and across age cohorts, with qualifications in the oldest stratum (age 75-85). CONCLUSIONS: ACEs are related to multimorbidity, directly and via social engagement and allostatic load. This is the first study to show mediated pathways between early adversity and multimorbidity in adulthood. It provides a platform for understanding multimorbidity as a lifespan dynamic informing the co-occurrence of the varied disease processes represented in multimorbidity.

Components of Outpatient Child and Youth Concurrent Disorders Programs: A Critical Interpretive Synthesis: Composantes des programmes de troubles concomitants des enfants et des jeunes ambulatoires : une synthèse interprétative critique.

OBJECTIVE: Co-occurring mental health and substance use disorders (concurrent disorders) lead to significant morbidity in children and youth. Programs for integrated treatment of concurrent disorders have been developed; however, there exists little guidance outlining their structure and activities. Our objective was to synthesize available information on outpatient child and youth concurrent disorders programs and produce a comprehensive framework detailing the components of such programs. METHODS: We used a four-stage critical interpretive synthesis design: (1) systematic review of published and grey literature, (2) data abstraction to identify program components and purposive sampling to fill identified gaps, (3) organization of components into a structured framework, (4) feedback from programs. We employed an iterative process by which programs reviewed data abstraction and framework development and provided feedback. RESULTS: Through systematic review (yielding 1,408 records total and 7 records eligible for inclusion) and outreach strategies (yielding an additional 7 eligible records), we identified 11 programs (4 American, 7 Canadian) and 2 theoretical models from which data could be abstracted. Program activities were categorized into 12 overarching constructs that make up the components of the framework: accessibility, engagement, family involvement, integrated assessment, psychotherapy for patients, psychotherapy for families, medication management, health promotion, case management, vocational support, recreation and social support, and transition services. Program components are informed by the philosophical orientation of the program and models of care. This framework considers health system factors, clinical service factors, program development, and community partnership that impact program structure and activities. Multidisciplinary teams provide care and include addiction medicine, psychiatry, psychology, nursing, social work, occupational therapy, recreation therapy, peer support, and program evaluation. CONCLUSION: We developed a comprehensive framework describing components of child and youth outpatient concurrent disorders programs. This framework may assist programs currently operating, and those in development, to reflect on their structure and activities.

Factors influencing the implementation of an intimate partner violence intervention in nurse home visiting: A qualitative descriptive study.

AIMS: To identify factors that influenced: (1) integration of an intimate partner violence intervention into the Nurse-Family Partnership programme and (2) utilization of the intervention with fidelity to the clinical pathway by nurses in their home visits. DESIGN: A qualitative descriptive study embedded in the intervention arm (n = 7 sites) of a 15-site cluster randomized clinical trial to evaluate the intimate partner violence intervention. METHODS: Semi-structured interviews (n = 13) were conducted with supervisors. Nurses at the seven sites shared their experiences in focus groups conducted at two time points (n = 14 focus groups, 12 months after baseline and following collection of client trial data). Qualitative data were generated between May 2012 and September 2016, with this post hoc analysis completed in 2021. Focus group data were analysed using a rapid qualitative analysis technique. Conventional content analysis was used to categorize data from the supervisor interviews. RESULTS: Integration was negatively impacted by: (1) a lack of centralized programme support and (2) competing programme demands. At the practice level, multiple factors related to supervisor capacity, preservation of the nurse-client relationship and nurse, client and intervention attributes influenced nurses' capacity to address intimate partner violence with fidelity to the clinical pathway. A lack of privacy in home visits was the most common barrier to addressing clients' experiences of violence. The need for increased time for nurses to develop clinical expertise prior to the evaluation of the intervention was also identified. CONCLUSION: Before implementing an intimate partner violence intervention, home visitation programmes need to attend to site readiness, provide support to supervisors to facilitate implementation, and provide nurses with time to develop the expertise and clinical judgement required to use a complex intervention whilst also respecting clients' agency to determine when and how they will respond to the violence in their relationships.ImpactWhat problem did the study address? Given the positive impacts that participating in the Nurse-Family Partnership intimate partner violence education had on nurse home visitors' attitudes and confidence to address this type of violence experienced by first-time mothers, it was important to understand what factors contributed to the low fidelity of intervention implementation in practice, a factor that may help to explain the lack of client-level impacts on maternal outcomes. What were the main findings? Implementation of an intimate partner violence intervention in a nurse home visiting programme was influenced by contextual factors at both programme and practice levels. At the practice level, a lack of privacy in the home limited nurses' capacity to use the intervention. Supervisors were identified as having an important role to support nurses develop the expertise to use the intervention. Nurses also consistently balanced the intervention requirements to address intimate partner violence with an understanding of the complexity of this type of violence in young women's lives and respect for clients' agency to determine when and how they will respond to the violence in their relationships. Where and on whom will the research have an impact? These findings will be of interest to: (1) researchers developing and evaluating complex nursing interventions to address intimate partner violence in home visitation programmes and (2) stakeholders leading the implementation of novel innovations in the Nurse-Family Partnership programme.

Associations between Lifetime Spanking/Slapping and Adolescent Physical and Mental Health and Behavioral Outcomes.

BACKGROUND: Many parents use physical forms of punishment, including spanking to correct perceived misbehavior. While some authors suggest spanking/slapping is a distinct and "milder" form of physical punishment, parents' use of spanking is consistently associated with poor outcomes for their children. However, less is known about the relationship between spanking/slapping and health and behavioral outcomes in adolescence independent of other childhood adversities. OBJECTIVES: The objectives of this study were to examine the associations between lifetime experiences of spanking on the bottom and/or slapping on the hand and 3 adolescent outcomes: (a) mental health disorders, (b) physical health conditions, and (c) defiant behaviors, after adjusting for other types of childhood adversities and child maltreatment. METHODS: Cross-sectional data from the provincially representative 2014 Ontario Child Health Study (N = 6,537 dwellings, response rate = 50.8%) were used. The current study focused on one selected child aged 14 to 17 years within a household (n = 1,883) with data collected from the adolescent and the parent/caregiver. Logistic regression models were used to identify associations with lifetime experiences of spanking/slapping 3 or more times (vs. 0 to 2 times). RESULTS: Lifetime spanking/slapping was independently associated with increased odds of mental health disorders, physical health conditions, and defiant behaviors in adolescence after adjusting for childhood adversities and child maltreatment (unadjusted and adjusted odds ratios ranging from 1.29 to 2.19). CONCLUSIONS: These findings suggest that lifetime spanking/slapping is uniquely associated with harmful mental, physical, and behavioral outcomes in adolescence, and efforts should focus on its prevention.

Emotion regulation moderates between maternal adverse childhood experiences (ACEs) and oxytocin response.

Exposure to adverse childhood experiences (ACEs) is associated with oxytocin dysregulation in women, such as decreased peripheral oxytocin concentrations, but little is known about vulnerability markers for oxytocin dysregulation in mothers exposed to ACEs. Identifying vulnerability markers may help inform future targets for prevention and intervention programmes. This study provided a preliminary examination of emotion regulation as a potential moderator of the association between maternal ACEs and peripheral oxytocin levels. The current study included a sample of 38 postpartum women. Women completed questionnaires on exposure to ACEs and difficulties with emotion regulation. At a clinic visit at 9 months postpartum, women provided plasma and salivary oxytocin samples anchored around a mother-infant interaction. Associations between maternal ACEs, three dimensions of difficulties with emotion regulation, and peripheral oxytocin concentrations were examined. Linear regression analyses showed that greater difficulties engaging in goal-directed behaviour (ß = - 0.50, p = 0.01) and more limited access to effective emotion regulation strategies (ß = - 0.68, p < 0.001) were related to reduced plasma oxytocin concentrations in postpartum women. Furthermore, in postpartum women reporting greater exposure to ACEs, higher levels of nonacceptance of emotional responses (ß = - 0.55, p = 0.01) and more limited access to effective emotion regulation strategies (ß = - 0.54, p = 0.01) were associated with reduced salivary oxytocin response (i.e. decreased change in oxytocin concentrations from baseline) following mother-infant interaction. Difficulties with emotion regulation may serve as a vulnerability marker for oxytocin dysregulation in postpartum women exposed to ACEs, and this suggests that emotion regulation may be an important target for future clinical interventions. Future research is recommended which replicates these preliminary results and which examines how emotion regulation and peripheral oxytocin levels in mothers exposed to ACEs are associated with parenting and child development outcomes.

Associations between spanking beliefs and reported spanking among adolescents-parent/caregiver dyads in a Canadian sample.

BACKGROUND: Research consistently demonstrates that physical punishment of children including "spanking" is harmful. Interest in effective prevention is growing rapidly. The aim of the current study is to examine spanking beliefs among adolescents and parents in relation to reports of spanking that the adolescents experienced before 11 years of age. METHODS: Data were drawn from Wave 1 of a study conducted in 2017-2018 that included adolescents (14-17 years old) and one of their parents/caregivers from Manitoba, Canada (n = 1000 pairs). The study objectives were to examine: 1) spanking beliefs of adolescents and their parents; 2) the correlation between parent and adolescent spanking beliefs; 3) whether parents perceive the words "spank" vs. "hit" differently using intraclass correlation; 4) the association between parents' beliefs about spanking and parent- and adolescent-reported use of it; and 5) the relationship between sociodemographic variables and spanking. The data were analyzed using descriptive statistics, Spearman's correlation, intraclass correlation, and binary and multinomial logistic regression analyses. RESULTS: The prevalence of adolescent-reported and parents'-reported spanking were 46.0% and 39.6%, respectively. The proportions agreeing that spanking is a normal part of parenting were similar among adolescents (22.0%) and parents (18.5%), and were moderately correlated (intraclass correlation = 0.38, SE = 0.038). More than five times as many parents believed that "spanking" is necessary (19.5%) than believed that "hitting" is necessary (3.5%). Parents' positive spanking beliefs were associated with increased likelihood of adolescent- and parent-reported spanking. Few significant associations were found between sociodemographic variables and parent-reported or adolescent-reported spanking. CONCLUSIONS: Adolescents' spanking beliefs are related to their parents' spanking beliefs, suggesting that they are transmitted across generations. Public education and law reform are needed to decrease the normalization and perceived necessity of spanking in child-rearing. Efforts should include improving the understanding that spanking is a form of violence against children. With only a few significant differences noted between sociodemographic variables and parent- and adolescent- reported spanking and the prevalent use of spanking across all sociodemographic variable categories, it may be useful to develop universal approaches to awareness-raising and implementation of education strategies in Canada.

Adolescent health outcomes: associations with child maltreatment and peer victimization.

BACKGROUND: Child maltreatment (CM) and peer victimization (PV) are serious issues affecting children and adolescents. Despite the interrelatedness of these exposures, few studies have investigated their co-occurrence and combined impact on health outcomes. The study objectives were to determine the overall and sex-specific prevalence of lifetime exposure to CM and past-month exposure to PV in adolescents, and the impact of CM and PV co-occurrence on non-suicidal self-injury, suicidality, mental health disorders, and physical health conditions. METHODS: Adolescents aged 14-17 years (n = 2,910) from the 2014 Ontario Child Health Study were included. CM included physical, sexual, and emotional abuse, physical neglect, and exposure to intimate partner violence. PV included school-based, cyber, and discriminatory victimization. Logistic regression was used to compare prevalence by sex, examine independent associations and interaction effects in sex-stratified models and in the entire sample, and cumulative effects in the entire sample. RESULTS: About 10% of the sample reported exposure to both CM and PV. Sex differences were as follows: females had increased odds of CM, self-injury, suicidality, and internalizing disorders, and males had greater odds of PV, externalizing disorders, and physical health conditions. Significant cumulative and interaction effects were found in the entire sample and interaction effects were found in sex-stratified models, indicating that the presence of both CM and PV magnifies the effect on self-injury and all suicide outcomes for females, and on suicidal ideation, suicide attempts, and mental health disorders for males. CONCLUSIONS: Experiencing both CM and PV substantially increases the odds of poor health outcomes among adolescents, and moderating relationships affect females and males differently. Continued research is needed to develop effective prevention strategies and to examine protective factors that may mitigate these adverse health outcomes, including potential sex differences.

Adverse childhood experiences and other risk factors associated with adolescent and young adult vaping over time: a longitudinal study.

BACKGROUND: Vaping among adolescents and young adults is a significant public health concern worldwide. Understanding which risk factors are associated with vaping is important to help inform evidence-based prevention and intervention strategies. There are several gaps in the current literature examining these associations such as limited longitudinal research. We examined the association between parental smoking/vaping, adolescent sex, mental disorders in adolescence, 13 adverse childhood experiences (ACEs) and a) any vaping and b) course of vaping across two time points among adolescents and young adults. METHODS: Data were from Waves 1 and 2 of the longitudinal Well-Being and Experiences Study (The WE Study) in Manitoba, Canada which collected data from a community sample of adolescents (14 to 17 years) and their parent/caregiver in Wave 1 in 2017-18 and the adolescents/young adults only in Wave 2 in 2019. A total of 752 adolescents/young adults (72.4% of the original cohort) completed both waves of the study. Binary and multinomial logistic regressions were conducted to understand the relationship between the 16 risk factors and the two vaping outcomes. RESULTS: Vaping prevalence was 45.5% for any vaping, 2.7% for Wave 1 vaping only, 19.7% for new onset Wave 2 vaping, and 21.2% for vaping at both waves. After adjusting for covariates, the majority of risk factors examined were associated with any adolescent or young adult vaping, including: parental smoking or vaping, emotional abuse, emotional neglect, exposure to verbal intimate partner violence, household substance use, household mental illness, parental separation/divorce, parental problems with police, foster care or contact with a child protective organization, an unsafe neighbourhood, and peer victimization. The majority of these risk factors, as well as adolescent mental health and parental gambling, were associated with different courses of vaping across the two time points. CONCLUSIONS: The findings emphasize the need for early vaping prevention and identified several ACEs and other factors that were associated with adolescent and young adult vaping and course of vaping. These identified ACEs and risk factors can help inform programs, strategies, and potential groups to target for vaping interventions.

Brain, interrupted: alpha/delta EEG ratio in survivors of pre- and post-natal adversity.

RESULTS: Young adults born at extremely low birth weight (prenatal adversity; N = 64, Mage = 23.14 years, SDage = 1.26 years) had a lower alpha/delta ratio score compared to normal birth weight controls (N = 76, Mage = 23.60 years, SDage = 1.09 years), while youth exposed to child maltreatment (postnatal adversity; N = 39, Mage = 16.18 years, SDage = 1.15) had a higher alpha/delta ratio compared to controls (N = 23, Mage = 16.00 years, SDage = 1.50 years). CONCLUSIONS: Our results suggest that being exposed to pre- and post-natal adversity may have different long-term consequences on brain development. We speculate that these differences might be associated with some of the different functional outcomes known to characterize each type of adverse experience.

The trajectories of depressive symptoms among working adults during the COVID-19 pandemic: a longitudinal analysis of the InHamilton COVID-19 study.

BACKGROUND: Longitudinal studies examining the impact of changes in COVID-19 pandemic-related stressors and experiences, and coping styles on the mental health trajectory of employed individuals during the lockdown are limited. The study examined the mental health trajectories of a sample of employed adults in Hamilton, Ontario during the initial lockdown and after the re-opening following the first wave in Canada. Further, this study also identified the pandemic-related stressors and coping strategies associated with changes in depressive symptoms in employed adults during the COVID-19 pandemic. METHODS: The InHamilton COVID-19 longitudinal study involved 579 employees aged 22-88 years from a large public university in an urban area of Hamilton, Ontario at baseline (April 2020). Participants were followed monthly with 6 waves of data collected between April and November 2020. A growth mixture modeling approach was used to identify distinct groups of adults who followed a similar pattern of depressive symptoms over time and to describe the longitudinal change in the outcome within and among the identified sub-groups. RESULTS: Our results showed two distinct trajectories of change with 66.2% of participants displaying low-consistent patterns of depressive symptoms, and 33.8% of participants displaying high-increasing depressive symptom patterns. COVID-19 pandemic-related experiences including health concerns, caregiving burden, and lack of access to resources were associated with worsening of the depressive symptom trajectories. Frequent use of dysfunctional coping strategies and less frequent use of emotion-focused coping strategies were associated with the high and increasing depressive symptom pattern. CONCLUSIONS: The negative mental health impacts of the COVID-19 pandemic are specific to subgroups within the population and stressors may persist and worsen over time. Providing access to evidence-informed approaches that foster adaptive coping, alleviate the depressive symptoms, and promote the mental health of working adults is critical.

Nurse-Family Partnership nurses' attitudes and confidence in identifying and responding to intimate partner violence: An explanatory sequential mixed methods evaluation.

AIMS: To evaluate the effect of an intimate partner violence intervention education component on nurses' attitudes in addressing intimate partner violence; complementary aims included understanding nurses' perceptions of the education and how it influenced their attitudes and confidence to address intimate partner violence in practice. DESIGN: An explanatory sequential mixed methods design embedded within a 15-site cluster randomized clinical trial that evaluated an intimate partner violence intervention within the Nurse-Family Partnership programme. METHODS: Data were collected between February 2011 and September 2016. Quantitative assessment of nurses' attitudes about addressing intimate partner violence was completed by nurses in the intervention (n = 77) and control groups (n = 101) at baseline, 12 months and at study closure using the Public Health Nurses' Responses to Women Who Are Abused Scale. Qualitative data were collected from nurses in the intervention group at two timepoints (n = 14 focus groups) and focused on their perceptions of the education component. Data were analysed using content analysis. RESULTS: Nurses in the intervention group reported large improvements in their thoughts, feelings and perceived behaviours related to addressing intimate partner violence; a strong effect of the education was found from baseline to 12 months and baseline to study closure timepoints. Nurses reported that the education component was acceptable and increased their confidence to address intimate partner violence. CONCLUSION: Nurses reported improved attitudes about and confidence in addressing intimate partner violence after receiving the education component. However, these findings need to be considered together with trial results showing no main effects for clients, and a low level of intervention fidelity. IMPACT: These evaluation findings underscore that improvement in nurses' self-reported educational outcomes about addressing intimate partner violence cannot be assumed to result in adherence to intervention implementation or improvement in client outcomes. These are important considerations for developing nurse education on intimate partner violence.

Psychophysiological influences on personality trajectories in adolescent females exposed to child maltreatment.

Although child maltreatment is a major public health concern, which adversely affects psychological and physical development, we know relatively little concerning psychophysiological and personality factors that may modify risk in children exposed to maltreatment. Using a three-wave, short-term prospective design, we examined the influence of individual differences in two disparate psychophysiological measures of risk (i.e., resting frontal brain electrical activity and respiratory sinus arrhythmia) on the trajectories of extraversion and neuroticism in a sample of female adolescents (N = 55; M age = 14.02 years) exposed to child maltreatment. Adolescents exposed to child maltreatment with relatively higher left frontal absolute alpha power (i.e., lower brain activity) at rest exhibited increasing trajectories of extraversion, and adolescents exposed to child maltreatment with relatively lower respiratory sinus arrhythmia at rest displayed increasing trajectories of neuroticism over 1 year. Individual differences in psychophysiological measures indexing resting central and peripheral nervous system activity may therefore differentially influence personality characteristics in adolescent females exposed to child maltreatment.

Exposure to family violence from childhood to adulthood.

BACKGROUND: Both childhood maltreatment (CM) and intimate partner violence (IPV) are public health problems that have been related to a wide range of adverse health consequences. However, studies examining associations between specific types of CM and experiencing IPV in adulthood have yielded conflicting results. METHODS: Using data from 10,608 men and 11,458 women aged 18 or older from Canada's 2014 General Social Survey, we examined associations between three types of CM-childhood physical abuse (CPA), childhood sexual abuse (CSA), and childhood exposure to IPV -and subsequent intimate partner violence (IPV) in adulthood (physical, sexual or emotional). RESULTS: When potential confounders were controlled, CPA, CSA and childhood exposure to IPV were associated with IPV in adulthood for both sexes (odds ratios, 1.7, 1.8 and 2.0 for men, and 2.2, 2.0 and 2.1 for women). When severity and frequency of CM were examined, a dose-response relationship between all three types of CM and IPV in adulthood was observed among women (meaning that as the severity/frequency of CM increased, the likelihood of reporting IPV also increased); among men, a dose-response relationship was observed only for CPA. CONCLUSIONS: The association between CM and IPV in adulthood is particularly concerning because experiencing multiple forms of trauma has cumulative effects. Lifespan studies have shown that individuals who experience multiple incidents of abuse exhibit the highest levels of impairment. This underscores the importance of programs to eradicate both CM and IPV. This underscores the importance of programs to eradicate both CM and IPV. Future research should focus on assessing interventions designed to promote healthy relationships and the provision of emotional support and coping mechanisms to children and families in abusive situations.

Identifying children exposed to maltreatment: a systematic review update.

BACKGROUND: Child maltreatment affects a significant number of children globally. Strategies have been developed to identify children suspected of having been exposed to maltreatment with the aim of reducing further maltreatment and impairment. This systematic review evaluates the accuracy of strategies for identifying children exposed to maltreatment. METHODS: We conducted a systematic search of seven databases: Medline, Embase, PsycINFO, Cumulative Index to Nursing and Allied Health Literature, Cochrane Libraries, Sociological Abstracts and the Education Resources Information Center. We included studies published from 1961 to July 2, 2019 estimating the accuracy of instruments for identifying potential maltreatment of children, including neglect, physical abuse, emotional abuse, and sexual abuse. We extracted data about accuracy and narratively synthesised the evidence. For five studies-where the population and setting matched known prevalence estimates in an emergency department setting-we calculated false positives and negatives. We assessed risk of bias using QUADAS-2. RESULTS: We included 32 articles (representing 31 studies) that evaluated various identification strategies, including three screening tools (SPUTOVAMO checklist, Escape instrument, and a 6-item screening questionnaire for child sex trafficking). No studies evaluated the effects of identification strategies on important outcomes for children. All studies were rated as having serious risk of bias (often because of verification bias). The findings suggest that use of the SPUTOVAMO and Escape screening tools at the population level (per 100,000) would result in hundreds of children being missed and thousands of children being over identified. CONCLUSIONS: There is low to very low certainty evidence that the use of screening tools may result in high numbers of children being falsely suspected or missed. These harms may outweigh the potential benefits of using such tools in practice (PROSPERO 2016:CRD42016039659).

Confirmatory factor analysis of adverse childhood experiences (ACEs) among a community-based sample of parents and adolescents.

BACKGROUND: Despite increased understanding of Adverse Childhood Experiences (ACEs), very little advancement has been made in how ACEs are defined and conceptualized. The current objectives were to determine: 1) how well a theoretically-derived ACEs model fit the data, and 2) the association of all ACEs and the ACEs factors with poor self-rated mental and physical health. METHODS: Data were obtained from the Well-Being and Experiences Study, survey data of adolescents aged 14 to 17 years (n = 1002) and their parents (n = 1000) in Manitoba, Canada collected from 2017 to 2018. Statistical methods included confirmatory factor analysis (CFA) and logistic regression models. RESULTS: The study findings indicated a two-factor solution for both the adolescent and parent sample as follows: a) child maltreatment and peer victimization and b) household challenges factors, provided the best fit to the data. All original and expanded ACEs loaded on one of these two factors and all individual ACEs were associated with either poor self-rated mental health, physical health or both in unadjusted models and with the majority of findings remaining statistically significant in adjusted models (Adjusted Odds Ratios ranged from 1.16-3.25 among parents and 1.12-8.02 among adolescents). Additionally, both factors were associated with poor mental and physical health. CONCLUSIONS: Findings confirm a two-factor structure (i.e., 1) child maltreatment and peer victimization and 2) household challenges) and indicate that the ACEs list should include original ACEs (i.e., physical abuse, sexual abuse, emotional abuse, emotional neglect, physical neglect, exposure to intimate partner violence (IPV), household substance use, household mental health problems, parental separation or divorce, parental problems with police) and expanded ACEs (i.e., spanking, peer victimization, household gambling problems, foster care placement or child protective organization (CPO) contact, poverty, and neighborhood safety).

Identifying and responding to child maltreatment when delivering family-based treatment-A qualitative study.

INTRODUCTION: This study describes practitioner strategies, perceptions, experiences with identifying and responding to child emotional abuse (CEA) and child exposure to intimate partner violence (CEIPV) when providing Family-Based Treatment (FBT) to children and adolescents with eating disorders. METHOD: Using qualitative interpretive description, this study recruited a purposeful sample of practitioners (N = 30, 90% female) implementing FBT for adolescent eating disorders. Semi-structured interviews focused on eliciting their perspectives regarding identifying and responding to CEA and CEIPV in practice. Interviews were conducted over the phone, were audio recorded, transcribed verbatim, and coded using conventional content analysis. Interim member checking, the thoughtful clinician test, and coding memos were used to ensure the integrity of the analysis. RESULTS: Participants were 31-57 years old and practicing FBT in five countries. Three data patterns emerged: (a) perceptions of child maltreatment prevalence and identification; (b) complicating factors; and finally (c) strategies to support family-based work. Practitioners described important considerations for CEA and CEIPV identification, as well as possible FBT adaptations that can support the safety of children and adolescents while simultaneously ensuring the treatment of the eating disorder. CONCLUSIONS: Practitioners describe a need for additional training to identify and respond to CEA and CEIPV within FBT and within practice more broadly. There is a need for trials that detail the appropriateness and efficacy of FBT for patients experiencing CEA and/or CEIPV.

The 2014 Ontario Child Health Study Emotional Behavioural Scales (OCHS-EBS) Part II: Psychometric Adequacy for Categorical Measurement of Selected DSM-5 Disorders.

OBJECTIVES: To compare the reliability and convergent validity of parent assessments from the Mini International Neuropsychiatric Interview for Children and Adolescents (MINI-KID-a structured diagnostic interview) and the Ontario Child Health Study Emotional Behavioural Scales (OCHS-EBS) symptom checklist for classifying conduct disorder (CD), conduct disorder or oppositional defiant disorder (CD-ODD), attention-deficit hyperactivity disorder (ADHD), major depressive disorder (MDD), generalized anxiety disorder (GAD), and separation anxiety disorder (SAD) based on DSM-5 criteria. METHODS: Data came from 283 parent-youth dyads aged 9 to 18 years. Parents and youth completed the assessments separately on 2 different occasions 7 to 14 days apart. After converting the OCHS-EBS scale scores to binary disorder classifications, we compare test-retest reliability estimates and use structural equation modelling (SEM) to compare estimates of convergent validity for the same disorders assessed by each instrument. RESULTS: Average test-retest reliabilities based on κ were 0.71 (MINI-KID) and 0.67 (OCHS-EBS). The average ß coefficients for 3 latent measures comprising the following indicators-parent perceptions of youth mental health need and impairment, diagnosis of specific disorders based on health professional communications and youth taking prescribed medication, and youth classifications of disorder based on the MINI-KID-were 0.67 (MINI-KID) and 0.69 (OCHS-EBS). CONCLUSION: The OCHS-EBS and MINI-KID achieve comparable levels of reliability and convergent validity for classifying child psychiatric disorder. The flexibility, low cost, and minimal respondent burden of checklists for classifying disorder make them well suited for studying disorder in the general population and screening in clinical settings.
