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.

We reviewed comments and feedback from editors, peer reviewers of Campbell submissions, and authors; for example, that the Campbell MECCIR was long and some of the items in the reporting and conduct checklists were difficult to cross-reference. We also wanted to make the checklist more relevant for reviews of associations or risk factors and other quantitative non-intervention review types, which we welcome in Campbell. Thus, our aim was to develop a shorter, more holistic guidance and checklist of Campbell Standards, encompassing both conduct and reporting of these standards within the same checklist.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Methods&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Our updated Campbell Standards will be a living document. To develop this first iteration, we invited Campbell members to join a virtual working group; we sought experience in conducting Campbell systematic reviews and in conducting methods editor reviews for Campbell. We aligned the items from the MECCIR for conduct and reporting, then compared the principles of conduct that apply across review types to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)-literature search extension (S) and PRISMA-2020 reporting standards. We discussed each section with the aim of developing a parsimonious checklist with explanatory guidance while avoiding losing important concepts that are relevant to all types of reviews. We held nine meetings to discuss each section in detail between September 2022 and March 2023. We circulated this initial checklist and guidance to all Campbell editors, methods editors, information specialists and co-chairs to seek their feedback. All feedback was discussed by the working group and incorporated to the Standards or, if not incorporated, a formal response was returned about the rationale for why the feedback was not incorporated.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Campbell Policy&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;The guidance includes seven main sections with 35 items multifaceted but distinct concepts that authors must adhere to when conducting Campbell reviews.
