Intimate partner violence and child attachment: A systematic review and meta-analysis.

BACKGROUND: Intimate Partner Violence (IPV) is associated with increased risk of impairment to a child's emotional, behavioural, and psychological functioning. Further, the presence of IPV is negatively associated with a child's attachment to their primary caregivers, which is an additional risk factor for social, emotional, and psychological impairment. OBJECTIVE: The aim of this systematic review and meta-analysis was to synthesise the evidence on the association between IPV and the attachment of infants, children, and adolescents to their primary caregiver/s. METHOD: A systematic review was completed, in accordance with the PRISMA statement, on IPV and the parent-child attachment of infants, children, and adolescents (18 years and younger). Meta-analyses were conducted to estimate the magnitude of these associations. RESULTS: A total of 15 studies were included. IPV was significantly associated with less secure child attachment. The pooled effect sizes (Pearson's r) for both longitudinal studies (n = 5) and cross-sectional and retrospective studies combined (n = 10) were small (r = -.22, 95 % CI [-.32, -.12], p < .001; r = -.10, 95 % CI [-.203, -.001], p = .048). Subgroup analyses identified that the effect size was larger when IPV and attachment were measured during infancy compared to childhood, and when attachment was measured via observational methods compared to self-report. CONCLUSION: While the current literature base is limited, findings can inform further research alongside clinical assessment and intervention. It can also help guide attachment- and family-based intervention for families impacted by IPV.

Risk and protective factors for depression that adolescents can modify: a systematic review and meta-analysis of longitudinal studies.

BACKGROUND: Adolescence is a peak time for the onset of depression, but little is known about what adolescents can do to reduce their own level of risk. To fill this gap, a review was carried out to identify risk and protective factors for depression during adolescence that are modifiable by the young person. METHODS: Employing the PRISMA method, we conducted a systematic review and meta-analysis of longitudinal studies to identify risk and protective factors during the adolescent period (aged 12-18 years) that are potentially modifiable by the young person without professional intervention or assistance. Stouffer׳s method of combining p values was used to determine whether associations between variables were reliable, and meta-analyses were conducted to estimate the mean effect sizes of associations. RESULTS: We identified 113 publications which met the inclusion criteria. Putative risk factors implicated in the development of depression for which there is a sound evidence base, and which are potentially modifiable during adolescence without professional intervention, are: substance use (alcohol, tobacco, cannabis, other illicit drugs, and polydrug use); dieting; negative coping strategies; and weight. Modifiable protective factors with a sound evidence base are healthy diet and sleep. LIMITATIONS: Limitations include not systematically reviewing moderators and mediators, the lack of generalisability across cultures or to younger children or young adults, and the inability to conduct a meta-analysis on all included studies. CONCLUSIONS: Findings from this review suggest that future health education campaigns or self-help prevention interventions targeting adolescent depression should aim to reduce substance use (alcohol, tobacco, cannabis, other illicit drugs, and polydrug use); dieting; and negative coping strategies; and promote healthy weight; diet; and sleep patterns.

Parental factors associated with depression and anxiety in young people: a systematic review and meta-analysis.

BACKGROUND: There is a burgeoning and varied literature examining the associations between parental factors and depression or anxiety disorders in young people. However, there is hitherto no systematic review of this complex literature with a focus on the 12-18 years age range, when the first onset for these disorders peaks. Furthermore, to facilitate the application of the evidence in prevention, a focus on modifiable factors is required. METHODS: Employing the PRISMA method, we conducted a systematic review of parental factors associated with depression and anxiety disorders in young people which parents can potentially modify. RESULTS: We identified 181 articles altogether, with 140 examining depression, 17 examining anxiety problems, and 24 examining both outcomes. Stouffer's method of combining p values was used to determine whether associations between variables were reliable, and meta-analyses were conducted to estimate the mean effect sizes of associations between each parental factor and outcome. LIMITATIONS: Limitations include sacrificing micro-level detail for a macro-level synthesis of the literature, not systematically reviewing moderators and mediators, the lack of generalizability across cultures and to younger or adult children, and the inability to conduct a meta-analysis on all included studies. CONCLUSIONS: Parental factors with a sound evidence base indicating increased risk for both depression and anxiety include less warmth, more inter-parental conflict, over-involvement, and aversiveness; and for depression additionally, they include less autonomy granting and monitoring.
