Results
In the total sample, the job crafting intervention program showed a non-significant effect on work engagement at both 3-month and 6-month follow-up. Also, job crafting did not improve significantly. However, the program showed a significant intervention effect on work engagement (p = 0.04) with small effect size (Cohen's d = 0.33 at 3-month follow-up) of workers in a lower job crafting subgroup.
