The Effectiveness of a Job Crafting, Strengths Use, and Deficit Correction Intervention on Employee Proactive Behaviors and Well-Being: A Randomized Controlled Trial

Abstract

The present study evaluates the effectiveness of a mixed job crafting, strengths use, and deficit correction intervention on the proactive behaviors, work engagement, life satisfaction, and work-life balance of employees working in a home office setting. A two-armed (intervention vs. wait-list control group) randomized controlled trial with three measurement moments (pre-, post-intervention, and one-month follow-up) was designed to reach the study's goal. A sample of 80 participants part of a large multinational pharmaceutical company was randomly assigned to the intervention (n = 45) or wait-list control condition (n = 35). Mixed factorial analyses of variance showed that the combined job crafting, strengths use, and deficit correction intervention positively impacted life satisfaction (d = .47) and seeking challenging job demands (d = .44) in the short-term. There were no significant differences between the two groups regarding the other proactive behaviors, work engagement, or work-life balance. Moderator analyses revealed that autonomy and workload were moderators of the relationship between the intervention effectiveness and several outcomes (e.g., the intervention had a positive effect on the work-life balance of participants with low autonomy). Theoretical and practical implications are discussed.
