The population consisted of all couples attending counseling centers in Tehran during the last two months of the year 2021. A sample of 30 couples was selected using convenience sampling and randomly assigned to an experimental group (15 couples) and a control group (15 couples). The research instruments included the Ryff Psychological Well-being Scale (1988) and the Simons and Gaher Distress Tolerance Scale (2005). The experimental group received eight sessions of McDonald's (2007) solution-focused training in a group setting, whereas the control group received no intervention. Data were analyzed using covariance analysis with SPSS software version 21.</p> <p><strong>Findings:</strong> The results showed that solution-focused couples therapy had a significant effect on the dimensions of psychological well-being (F = 15.78, p = .001) and distress tolerance (F = 12.00, p = .001); these effects were maintained during the follow-up phase (p &lt; .001).</p> <p><strong>Conclusion:</strong> Given the results, therapists can employ solution-focused couples therapy to enhance psychological well-being and distress tolerance among couples, which significantly affects the stability and strength of families.</p> https://journals.kmanpub.com/index.php/aftj/article/download/2306/3033
