Intergenerational Cycles of Maltreatment: A Scoping Review of Psychosocial Risk and Protective Factors.

Child maltreatment tends to show intergenerational continuity. However, a significant proportion of maltreated parents break these cycles. Since several studies have investigated risk and protective factors associated with the intergenerational continuity of child maltreatment over the past decades, and no systematic review of the literature is available, this scoping review aimed to summarize studies documenting associated psychosocial risk and protective factors. A secondary objective was to document the prevalence of this phenomenon. A search in six major databases (PsycINFO, Scopus, Medline, Social Work Abstracts, ProQuest Dissertations/Theses, and Web of Science) was conducted. Studies involving human participants, presenting original findings, written in French or English, and of any type of design were included. There was no limit regarding the date of publication, except for theses/dissertations (5 years). A final sample of 51 papers was retained, 33 providing data on risk and protective factors and 18 providing only prevalence data. Results indicate that parents' individual characteristics (e.g., mental health, age), childhood adversity (e.g., multiple forms of adversity), relational (e.g., couples' adjustment, attachment, social support), and contextual factors (e.g., disadvantage, community violence) are relevant to the intergenerational continuity of child maltreatment. Prevalence rates of continuity ranged from 7% to 88%. Major limitations of reviewed studies are discussed. Continued efforts to uncover the mechanisms associated with the intergenerational continuity of child maltreatment using strong methodological designs are necessary. Knowledge in this area could lead to the development of effective prevention strategies (e.g., mental health services for parents, family/dyadic interventions) to break harmful intergenerational cycles of violence.
