The statistical population includes medical students in Tehran who agreed to participate in the study.

Frost&#39;s Multidimensional Perfectionism Questionnaire and Watson et al.&#39;s (1988) Positive Affect Questionnaire were used to collect data. Positive group psychotherapy was administered by the researcher in 8 sessions for 4 weeks, two 60-minute sessions per week for the experimental group. The control group did not receive any intervention during this period. The results of the experiments were calculated using SPSS software.</span></span><span dir="RTL" lang="AR-SA" style="font-size:9.0pt"><span style="font-family:"Times New Roman",serif"></span></span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:normal"><span style="font-family:Calibri,sans-serif"><b><span style="font-size:9.0pt"><span cambria="" style="font-family:">Results</span></span></b><span style="font-size:9.0pt"><span cambria="" style="font-family:">: The findings of the study show that positive group psychotherapy has an effect on the level of medical students&#39; mood and significantly improves it.
