The statistical population included female welfare employees in Tabriz in 2024-2025, and a sample of 40 individuals (20 in the experimental group and 20 in the control group) was selected using multi-stage 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 & 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.</span> <strong><span>Results:</span></strong><span>The results showed that Dual- growth mindset training created a significant difference between the experimental and control groups (P=.021). Univariate analyses also confirmed a significant increase in post-test scores in the experimental group (job meaningfulness: F(1,37)=712.99, p<.001, η²=.729; work engagement: F(1,37)=12.72, p<.001, η²=.66; organizational vitality: F(1,37)=93.31, p<.001, η²=.463).</span> <strong><span>Conclusion:</span></strong><span>The findings support 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.</span> https://journal.iepa.ir/article_238452_d4e04fb74ad588feb787e59aa6e042de.pdf
