Objective:This research was conducted with the aim of investigating the effectiveness of Dual- growth mindsettraining on enhancing job meaningfulness, work engagement, and organizational vitality among female employees of the Tabriz Welfare Organization.
Method:The research method was semi-experimental with a pretest-posttest design and a control group. The statistical population included female welfare employees in Tabriz County in 2025, and a sample of 40 individuals (20 in the experimental group and 20 in the control group) was selected using cluster random sampling and randomly assigned. The educational intervention consisted of 15 sixty-minute sessions (7 sessions on self-incremental mindset based on Garofalo, 2016, and 8 sessions on job-incremental mindset based on Wrzesniewski and Dutton, 2001) implemented for the experimental group. The research instruments included the Job Meaningfulness Questionnaire by Steger et al. (2012), the Work Engagement Questionnaire by Salanova and Schaufeli (2001), and the Organizational Vitality Questionnaire by Kauffman (2007). Data were analyzed using multivariate and univariate covariance analysis.
Results:The results showed that Dual- growth mindsettraining created a significant difference between the experimental and control groups (P=0.021). Univariate analyses also confirmed a significant increase in post-test scores in the experimental group (job meaningfulness: F(1,37)=712.99, p<0.001, η²=0.729; work engagement: F(1,37)=12.72, p<0.001, η²=0.66; organizational vitality: F(1,37)=93.31, p<0.001, η²=0.463).
Discussion:These findings are consistent with Dweck's (2006) incremental mindset theory, and it is recommended that this intervention be included in the training programs of Iranian service organizations to enhance employees' psychological well-being.
