A growing body of intervention studies is concerned with improving the work-nonwork interface. Extant work-nonwork interventions are diverse in terms of content and effectiveness. We map these interventions onto work-nonwork theories that explain why the interventions should improve proximal work-nonwork outcomes (i.e., conflict, enrichment, balance). Our resulting integrative framework suggests that interventions can affect work-nonwork outcomes via distinct mechanisms, which can be delineated according to their (a) content valence (i.e., increasing resources/positive characteristics or decreasing demands/negative characteristics); (b) locality (i.e., personal or contextual factors); and (c) domain (i.e., work, the nonwork, or the boundary-spanning). We further provide a meta-analytic review of the efficacy of such interventions based on 6,680 participants within 26 pre-post control group design intervention studies. The meta-analytic results reveal an overall significant main effect across all identified interventions for improving proximal work-nonwork outcomes. When comparing different kinds of interventions aimed at increasing resources, we found beneficial effects for interventions targeting personal resources over contextual resources and interventions in the nonwork domain compared to interventions in the work or boundary-spanning domain. We conclude that work-nonwork interventions effectively improve the work-nonwork interface and discuss theoretical and practical implications of the more substantial effects and potential advantages of interventions aimed at enhancing personal resources in the nonwork domain. Finally, we provide concrete recommendations for future research and elaborate on the type of studies we would like to see in terms of interventions targeting the reduction of demands, for which we found only a limited number of studies.

工作-非工作干预的有效性：理论综合和荟萃分析。

越来越多的干预研究关注改善工作与非工作界面。现有的工作-非工作干预措施在内容和有效性方面各不相同。我们将这些干预措施映射到工作-非工作理论，解释为什么干预措施应该改善最近的工作-非工作结果（即冲突、充实、平衡）。我们由此产生的综合框架表明，干预可以通过不同的机制影响工作-非工作结果，这些机制可以根据它们的（a）内容效价（即增加资源/积极特征或减少需求/消极特征）来描述；(b) 地点（即个人或背景因素）；(c) 域（即工作、非工作或边界跨越）。我们进一步提供了基于 6 的此类干预措施功效的元分析审查，26 个前后控制组设计干预研究中的 680 名参与者。荟萃分析结果揭示了所有已确定的干预措施对改善近端工作-非工作结果的总体显着主要影响。在比较旨在增加资源的不同类型的干预措施时，我们发现与工作或跨界领域的干预措施相比，针对个人资源的干预措施对情境资源和非工作领域的干预措施具有有益影响。我们得出结论，工作-非工作干预有效地改善了工作-非工作界面，并讨论了旨在增强非工作领域个人资源的干预措施的更实质性影响和潜在优势的理论和实践意义。最后，我们为未来的研究提供了具体的建议，并详细阐述了我们希望在旨在减少需求的干预措施方面看到的研究类型，我们只找到了数量有限的研究。（PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
