Participants completed the 18-item short form of Ryff&rsquo;s Psychological Well-Being Scale (&alpha; = 0.83), the Emotional Exhaustion Scale (ECE; &alpha; = 0.84), and the Psychological Hardiness Scale (&alpha; = 0.85). Data were analyzed using Pearson correlation and multiple linear regression in SPSS 26.</span></span></span><br> <span style="font-size:12pt"><span style="line-height:150%"><span new="" roman="" style="font-family:" times=""><b>Results:</b> Emotional exhaustion was negatively associated with psychological well-being (r = -0.44, P < 0.01), while mental toughness showed a positive association (r = 0.43, P < 0.01), with the control dimension demonstrating the strongest correlation (r = 0.49, P < 0.01). The two variables together accounted for 26% of the variance in well-being (R&sup2; = 0.26, F = 42.67, P < 0.001). Both were significantly associated with all six dimensions of psychological well-being.</span></span></span><br> <span style="font-size:12pt"><span style="line-height:150%"><span new="" roman="" style="font-family:" times=""><b>Conclusion:</b> Findings suggest emotional exhaustion is a risk factor and mental toughness a protective resource in this sample. Strengthening the sense of control may buffer negative associations. However, due to the cross-sectional design, causal inferences cannot be made, and the modest explained variance indicates other important factors. Generalizability is limited to similar Iranian high school populations.</span></span></span><br> <br> &nbsp; Psychological well-being, Emotional exhaustion, Mental toughness, Hardiness, Adolescents 0 0 http://jpcp.uswr.ac.ir/browse.php?a_code=A-10-1136-1&slc_lang=en&sid=1 Zahra Ahmadi Basiri nazanin.malichian@iau.ir No Department of Psychology, Khom.C., Islamic Azad University, Khomein, Iran Abbas Bayat Asghari bayatasghari@proton.me Yes Department of Psychology, Khom.C., Islamic Azad University, Khomein, Iran Hossein Yazdani yazdaniihssn@gmail.com No Department of Psychology, Na.C., Islamic Azad University, Najafabad, Iran
