Participants, recruited via purposive sampling from Ahvaz medical centers, completed the translated Social Effort and Conscientiousness Scale, the Social Functioning Questionnaire, the Positive and Negative Syndrome Scale, and the Calgary Depression Scale for Schizophrenia. The Social Effort and Conscientiousness Scale translation followed a forward-backward method. Data analysis, conducted using SPSS 27 and SmartPLS 3, included confirmatory factor analysis, assessment of convergent validity, discriminant validity (HTMT and Fornell-Larcker), and reliability analysis.</span></span></span></span></span><br> <span style=font-size:12pt><span style=line-height:normal><span style=font-family:Times New Roman,serif><b><span style=font-size:10.0pt><span style=font-family:Cambria,serif><span style=color:#4f81bd>Findings:</span></span></span></b><span style=font-size:10.0pt><span style=font-family:Cambria,serif> Confirmatory factor analysis confirmed the Social Effort and Conscientiousness Scale's two-factor structure, with all 12 items loading above 0.4. Model fit was acceptable (SRMR=0.067; CFI=0.94). High internal consistency was observed (α=0.92 overall; 0.93 for social effort; 0.77 for conscientiousness), as was composite reliability (0.92 overall; 0.94 and 0.77 for subscales). Convergent validity was established (AVE>0.5). Discriminant validity was supported by both HTMT (<0.9) and Fornell-Larcker criteria.</span></span></span></span></span><br> <span style=font-size:12pt><span style=line-height:normal><span style=font-family:Times New Roman,serif><b><span style=font-size:10.0pt><span style=font-family:Cambria,serif><span style=color:#4f81bd>Conclusion:</span></span></span></b> <span style=font-size:10.0pt><span style=font-family:Cambria,serif>The Persian version of the Social Effort and Conscientiousness Scale demonstrates satisfactory psychometric properties in individuals with schizophrenia.
