Improving work–nonwork balance and well‐being through a boundary fit microintervention
研究检验了一种自我引导的边界契合微干预（包含教育、目标设定和自我反思）对提升员工感知边界契合、工作非工作平衡满意度和主观幸福感的效果，并通过随机对照试验发现干预有效且感知边界契合起中介作用。
Abstract This study examines the effectiveness of a microintervention targeting the alignment between employees' preferred and enacted boundaries separating work and nonwork roles (i.e., boundary fit). Drawing on boundary fit theory and the action regulation at the work–family interface model, we developed a self‐guided boundary fit microintervention incorporating education, goal‐setting, and self‐reflection components. Based on a randomized controlled trial, we compared an experimental group with two control groups. We assessed changes in perceived boundary fit, work–nonwork balance satisfaction, and subjective well‐being across three waves—pre‐intervention (T1), post‐intervention (T2), and follow‐up (T3)—with two‐week intervals between assessments ( N T1–T2 = 90; N T1–T2–T3 = 75). Participants in the experimental group exhibited greater increases in these outcomes than both control groups. Mediation analyses revealed that increases in perceived boundary fit mediated the intervention's effects on work–nonwork balance satisfaction and subjective well‐being. Although the findings' generalizability may be constrained by the sample—comprising predominantly women and participants without caregiving responsibilities—the study contributes to the boundary management literature by demonstrating the effectiveness of a time‐efficient intervention and illuminating its underlying mechanisms.
