Asking youth and adults about child maltreatment: a review of government surveys.

OBJECTIVES: In this review we: (1) identify and describe nationally representative surveys with child maltreatment (CM) questions conducted by governments in low-income, middle-income and high-income countries and (2) describe procedures implemented to address respondents' safety and minimise potential distress. DESIGN: We conducted a systematic search across eight databases from 1 January 2000 to 5 July 2021 to identify original studies with information about relevant surveys. Additional information about surveys was obtained through survey methods studies, survey reports, survey websites or by identifying full questionnaires (when available). RESULTS: Forty-six studies representing 139 surveys (98 youth and 41 adult) conducted by governments from 105 countries were identified. Surveys implemented a variety of procedures to maximise the safety and/or reduce distress for respondents including providing the option to withdraw from the survey and/or securing confidentiality and privacy for the respondent. In many surveys, further steps were taken such as providing information for support services, providing sensitivity training to survey administrators when interviews were conducted, among others. A minority of surveys took additional steps to empirically assess potential distress experienced by respondents. CONCLUSIONS: Assessing risk and protective factors and developing effective interventions and policies are essential to reduce the burden of violence against children. While asking about experiences of CM requires careful consideration, procedures to maximise the safety and minimise potential distress to respondents have been successfully implemented globally, although practices differ across surveys. Further analysis is required to assist governments to implement the best possible safety protocols to protect respondents in future surveys.

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.

Childhood maltreatment as a risk factor for cancer: findings from a population-based survey of Canadian adults.

BACKGROUND: Childhood maltreatment (CM) is an established risk factor for various mental and substance use disorders. This study adds to existing evidence that CM may also be a risk factor for cancer. METHODS: Based on data from a sample of 9783 men and 12,132 women from the 2012 Canadian Community Health Survey - Mental Health (CCHS-MH), this analysis explores mediated associations between cancer in adulthood and different levels of exposure to three types of CM-childhood physical abuse (CPA), childhood sexual abuse (CSA), and childhood exposure to intimate partner violence (CEIPV). "Cancer" was defined as an affirmative response to either of these questions: "Do you have cancer?" or "Have you ever been diagnosed with cancer?" The potential mediators were: smoking, depression, alcohol abuse/dependence, life stress, obesity, and physical activity. RESULTS: For women, but not men, having experienced CM was significantly associated with a cancer diagnosis in adulthood, even when effects due to age and socio-demographic characteristics were controlled. Smoking, life stress, depression, and alcohol abuse/dependence reduced the strength of the association between CM and cancer in women. However, most associations remained statistically significant when controlling for effects due to these behavioural and other mediators. Evidence indicated a "dose-response" relationship, in that the likelihood of reporting cancer increased with the number of abuse types (CPA, CSA, CEIPV) reported, and with the severity of CPA. CONCLUSIONS: The analyses suggest an association between CM and cancer in women, even when the effects of known risk factors were taken into account. The association was graded, becoming stronger as CM exposure increased. Implications for the provision of cancer screening and other health care services to women with histories of CM to reduce health disparities are discussed.

The Decline of Child Sexual Abuse in Canada: Evidence From the 2014 General Social Survey.

OBJECTIVE: To provide evidence of trends in child sexual abuse (CSA) in Canada. METHODS: Using data from 15,801 males and 18,669 females who responded to the 2014 General Social Survey (GSS), we compared the prevalence of CSA by age cohorts. Age cohort patterns were examined for several sub-populations including males, females, Indigenous peoples, and people living in low-income households. RESULTS: After an increase in the post-World War II period, there has been a decline in CSA in Canada since the early 1990s. Findings indicate a decline for both sexes; although, the evidence is more compelling for females. There is also evidence of a decline for Indigenous peoples, for those living in low-income households, and regardless of the relationship to the perpetrator (i.e., family member, a teacher/professor/tutor, a babysitter, a nanny, other non-family member but known to the respondent, or a stranger). CONCLUSIONS: In Canada, evidence from 3 retrospective population surveys suggests a decline in CSA since the early 1990s. However, given the associated harm, continued progress to the eradication of CSA is essential.

Childhood Maltreatment as a Risk Factor for Arthritis: Findings From a Population-Based Survey of Canadian Adults.

OBJECTIVE: To establish whether there is a relationship between the frequency and severity of different types of childhood maltreatment and adulthood arthritis. METHODS: Analysis of the 2012 Canadian Community Health Survey-Mental Health included 21,889 respondents ages ≥18 years. Severity and frequency of childhood physical abuse (CPA), and childhood sexual abuse (CSA), and the frequency of childhood exposure to intimate partner violence (CEIPV) were assessed by asking about "things that may have happened to you before you were 16 in your school, in your neighborhood, or in your family." Respondents were also asked about chronic conditions diagnosed by a health professional, including arthritis. Covariates were sociodemographic characteristics, health risk variables (e.g., obesity), mental disorders, and a count of other chronic conditions. Multivariate logistic regression analysis was used to examine associations between childhood maltreatment and arthritis. RESULTS: A total of 17.5% of respondents reported arthritis. A higher prevalence of arthritis was observed for those who had experienced severe and/or frequent childhood maltreatment (32% for CPA and 27% for both CSA and CEIPV). These relationships persisted after controlling for sociodemographic variables. After controlling for all covariates, arthritis remained independently associated with severe and/or frequent CPA (dose-response relationship) and frequent CEIPV. CONCLUSION: We found that the greater the frequency and severity of childhood maltreatment, the greater the magnitude of association with arthritis. This might reflect the role of the enduring immune and metabolic abnormalities and chronic inflammation associated with childhood maltreatment in the etiopathogensis of osteoarthritis (OA) or be an indicator of the role of joint injury in causing OA.

Does mandatory reporting legislation increase contact with child protection? - a legal doctrinal review and an analytical examination.

BACKGROUND: Within Canadian provinces over the past half-century, legislation has been enacted to increase child protection organization (CPO) involvement in situations of child maltreatment (CM). This study had two objectives: 1) to document enactment dates of legislation for mandatory reporting of CM; 2) to examine reported CPO involvement among people reporting a CM history in relation to the timing of these legislative changes. METHODS: The history of mandatory reporting of CM was compiled using secondary sources and doctrinal legal review of provincial legislation. The 2012 Canadian Community Health Survey - Mental Health (CCHS-MH) with n = 18,561 was analyzed using birth cohorts to assess associations between the timing of legislation enactment and contact with CPO. RESULTS: All Canadian provinces currently have mandatory reporting of physical and sexual abuse; 8 out of 10 provinces have mandatory reporting for children's exposure to intimate partner violence. Increases in reporting CM to CPOs paralleled these laws' enactment, particularly for severe and frequent CM. CONCLUSIONS: These findings show that mandatory reporting laws increase reporting contact with CPO, particularly for severe and frequent CM. Whether they have had the intended effect of improving children's lives remains an important, unanswered question.

Childhood maltreatment as a risk factor for COPD: findings from a population-based survey of Canadian adults.

OBJECTIVE: The aim of this study was to examine the associations between childhood maltreatment (CM) and COPD in adulthood. METHODS: Data were from 15,902 respondents to the 2012 Canadian Community Health Survey - Mental Health. Multiple logistic regression models were used to examine associations between CM and COPD and the role of smoking and mental and substance use variables as mediators in associations. RESULTS: COPD in adulthood was related to CM, with associations differing by sex. Among females, COPD was related to childhood physical abuse (CPA), childhood sexual abuse, and childhood exposure to intimate partner violence, but in the fully adjusted models, the association with CPA did not persist. Among males, COPD was related to childhood exposure to intimate partner violence and severe and frequent CPA, but these associations did not persist in the fully adjusted models. CONCLUSION: Results from this study establish CM as a risk factor for COPD in adulthood. A large part of the association is attributable to cigarette smoking, particularly for males. These findings underscore the importance of interventions to prevent CM as well as programs to assist victims of CM in dealing with tobacco addiction.

Childhood maltreatment as a risk factor for diabetes: findings from a population-based survey of Canadian adults.

BACKGROUND: It is well established that childhood maltreatment (CM) is a risk factor for various mental and substance use disorders. To date, however, little research has focused on the possible long-term physical consequences of CM. Diabetes is a chronic disease, for which an association with CM has been postulated. METHODS: Based on data from a sample of 21,878 men and women from the 2012 Canadian Community Health Survey - Mental Health (CCHS - MH), this study examines associations between three types of CM (childhood physical abuse (CPA), childhood sexual abuse (CSA), and childhood exposure to intimate partner violence (CEIPV)) and diabetes in adulthood. Multiple logistic regression models were used to examine associations between CM and diabetes controlling for the effects of socio-demographic characteristics and risk factors for type 2 diabetes. RESULTS: When controlling socio-demographic characteristics, diabetes was significantly associated with reports of severe and frequent CPA (OR = 1.8) and severe and frequent CSA (OR = 2.2). A dose-response relationship was observed when co-occurrence of CSA and CPA was considered with the strongest association with diabetes being observed when both severe and frequent CSA and CPA were reported (OR = 2.6). Controlling for type 2 diabetes risk factors attenuated associations particularly for CPA. CEIPV was not significantly associated with having diabetes in adulthood. CONCLUSION: CPA and CSA are risk factors for diabetes. For the most part, associations between CPA and diabetes are mediated via risk factors for type 2 diabetes. Failure to consider severity and frequency of abuse may limit our understanding of the importance of CM as a risk factor for diabetes.

Commentary on Canadian child maltreatment data.

The issue of how to best collect child maltreatment data is a key concern within the Public Health Agency of Canada (PHAC). We argue that maltreatment data can be collected from children, adolescents, and parents with approaches that are accurate, methodologically robust, legal, and ethical. It has been done in other countries. First, we clarify ongoing child maltreatment data collection by the Canadian government and address PHAC initiatives to include child maltreatment questions in national contemporaneous surveys. Second, we identify examples of population-based studies with child, adolescent, and parent respondents. Third, we highlight some measurement considerations. Fourth, we address ethical considerations in conducting this type of research.

Anxiety and/or depression in 10-15-year-olds investigated by child welfare in Canada.

PURPOSE: To examine five types of child maltreatment and other risk correlates to establish associations with anxiety and/or depression confirmed or suspected in children investigated by child welfare services. METHODS: The present study used the data of a subsample of 10-15-year-olds (n = 4,381) investigated by child welfare services across Canada obtained from the Canadian Incidence Study of Reported Child Abuse and Neglect-2003. The analysis took into account the nested structure of the data by considering the variability existing among families and the clustering of siblings within them. Several models were analyzed for the construction of the presented hierarchical model. Striving for parsimony, we included only statistically significant variables in the final model. RESULTS: The strongest associations were found with child substance abuse, substantiated emotional maltreatment, primary caregiver's mental health problems, and substantiated sexual abuse. Among the child maltreatment variables, substantiated physical abuse and substantiated exposure to domestic violence did not show any statistically significant associations with anxiety and/or depression in the model. CONCLUSION: This analysis helped us in understanding child maltreatment and other adverse experiences in childhood that were related to anxiety and/or depression, which can further aid in the development of mental health and child welfare policies and programs.

Policy makers' perspectives on the utility of a national study of child maltreatment.

Reliable national child maltreatment data are needed for developing and modifying policies aimed at preventing child maltreatment and helping child victims of maltreatment. Health Canada hosted a daylong forum in 2002 to solicit feedback from senior Government of Canada policy and program officials involved in child welfare programs and research in regard to the data collected in the Canadian Incidence Study of Reported Child Abuse and Neglect (CIS). This article reviews the discussions and debates regarding the utility of the CIS data for government policy makers and reflects on the implications for surveillance and knowledge in the area of child maltreatment. The key themes are definitions and measurement issues, the value of enhanced and additional data, and challenges to linking research and practice.
