Job crafting, an employee-initiated job design/redesign, has become important for employees' well-being such as work engagement. This study examined the effectiveness of a newly developed job crafting intervention program on work engagement (as primary outcome), as well as job crafting and psychological distress (as secondary outcomes), using a pretest-posttest study design among Japanese employees.
Participants were managers of a private company and a private psychiatric hospital in Japan. The job crafting intervention program consisted of two 120-min sessions with a two-week interval between them. Outcomes were assessed at baseline (Time 1), post-intervention (Time 2), and a one-month follow-up (Time 3). The mixed growth model analyses were conducted using time (Time 1, Time 2, and Time 3) as an indicator of intervention effect. Effect sizes were calculated using Cohen's d.
The program showed a significant positive effect on work engagement (t = 2.20, p = 0.03) in the mixed growth model analyses, but with only small effect sizes (Cohen's d = 0.33 at Time 2 and 0.26 at Time 3). The program also significantly improved job crafting (t = 2.36, p = 0.02: Cohen's d = 0.36 at Time 2 and 0.47 at Time 3) and reduced psychological distress (t = -2.06, p = 0.04: Cohen's d = -0.15 at Time 2 and -0.31 at Time 3).
The study indicated that the newly developed job crafting intervention program was effective in increasing work engagement, as well as in improving job crafting and decreasing psychological distress, among Japanese managers.

工作重塑是一种由员工主动进行的工作设计/再设计，对于员工的工作投入等幸福感而言变得越来越重要。本研究采用预-后测试设计，在日本员工中检验了一项新开发的工作重塑干预计划对工作投入（主要结果）以及工作重塑和心理困扰（次要结果）的效果。
参与者为日本一家私营公司和一家私营精神病院的管理人员。工作重塑干预计划由两次 120 分钟的会议组成，两次会议之间间隔两周。在基线（时间 1）、干预后（时间 2）和一个月随访（时间 3）时评估结果。混合增长模型分析使用时间（时间 1、时间 2 和时间 3）作为干预效果的指标。使用 Cohen's d 计算效应大小。
在混合增长模型分析中，该计划显示对工作投入有显著的积极影响（t=2.20，p=0.03），但效应量较小（时间 2 时 Cohen's d=0.33，时间 3 时 Cohen's d=0.26）。该计划还显著改善了工作重塑（t=2.36，p=0.02：时间 2 时 Cohen's d=0.36，时间 3 时 Cohen's d=0.47）和减少了心理困扰（t=-2.06，p=0.04：时间 2 时 Cohen's d=-0.15，时间 3 时 Cohen's d=-0.31）。
该研究表明，新开发的工作重塑干预计划在提高日本管理人员的工作投入、改善工作重塑和减轻心理困扰方面是有效的。
