PROTOCOL: The association between adverse childhood experiences and employment outcomes: Protocol for a systematic review.

There is growing evidence of a link between adverse childhood experiences (ACEs) and health and economic outcomes. Previous systematic reviews synthesised evidence of the relationships between ACEs and various health and some economic outcomes such as healthcare costs and educational attainment. The primary aim of this systematic review is to synthesise the evidence on the relationship between ACEs and employment outcomes. MEDLINE, Psychology and Behavioural Sciences Collection (APA PsycInfo), ECONLIT, Sociological Abstracts, Social Science Research Network (SSRN) and Scopus will be searched using a predefined search strategy. Cross-sectional, cohort, or longitudinal studies published between 2000 and 2024 will be included. ACEs include abuse, neglect, household dysfunction, bullying, foster care, and racism that occur during childhood or adolescence. Employment outcomes include employment status, occupation, and income. Risk of bias of individual studies will be assessed using appropriate NHLBI-NHI quality assessment tools for each type of study. Proportions or means will be used to analyse and compare outcomes. If data allows, we will conduct meta-analysis. Sub-group analyses (e.g., by gender, age group, type and number of ACEs, and intersections of identities of study subjects will be conducted. Further analysis will be conducted to assess the mediators of the effect of ACEs on employment outcomes. By sythesising evidence of the association between ACEs and economic wellbeing later in life, this review will add evidence to the broader literature on poverty. The results of this synthesis will inform policies on child welfare and employment. Results of the review will be published in a peer-reviewed journal.
