اسكيزوفرني، يكي از اختلالات رواني وخيم بوده كه بر كيفيت زندگي مراقبان و اطرافيان آنها بسيار تاثير گذار مي باشد. اين پژوهش با هدف بررسي ويژگي هاي روان سنجي نسخه فارسي پرسشنامه كيفيت زندگي مراقبين بيماران مبتلا به اختلالات اسكيزوفرني انجام شد. روش بررسي اين پژوهش از نوع پژوهش هاي روش شناختي بوده و جامعه آن را تمام مراقبين بيماران مبتلا به اسكيزوفرني استان اصفهان در سال 1397 تشكيل مي دادند. به روش نمونه گيري مستمر، 155 نفر از مراقبين بيماران اسكيزوفرني سه بيمارستان اعصاب و روان و سه مركز نگهداري از بيماران اعصاب و روان مزمن تحت پوشش بهزيستي در يك بازه ي زماني سه ماهه انتخاب شدند و از آنها خواسته شد به پرسشنامه كيفيت زندگي مراقبين بيماران اسكيزوفرني Richieriو همكاران كه در اين مطالعه ترجمه شد و پرسشنامه كيفيت زندگي سازمان بهداشت جهاني Skevington وهمكاران پاسخ دهند. تعداد 13 نفر نيز جهت پايايي باز آزمايي انتخاب شدند. جهت بررسي پايايي پرسشنامه از روش آلفاي كرونباخ استفاده شد. نتيجه گيري كلي: نتايج به دست آمده نشان مي دهد نسخه فارسي پرسشنامه كيفيت زندگي مراقبين مبتلايان به اختلالات اسكيزوفرني روايي و پايايي نسبتا مطلوبي داشته و براي استفاده در مراقبين مبتلايان به اسكيزوفرني در جامعه ايران در مراكز درماني كاربرد دارد.

Schizophrenia is a severe psychological disorder, which adversely affects the life quality of the patients and their caregivers. The present study aimed to evaluate the psychometric properties of the Persian version of the schizophrenia caregiver quality of life questionnaire (S-CGQoL). Materials & Methods: This psychological study was conducted on all the caregivers of schizophrenia patients in Isfahan, Iran in 2018. In total, 200 caregivers of schizophrenia patients were selected via continuous sampling from three mental hospitals and three nursery centers during three months. Data were collected using the SCGQoL by Richieri et al. (2011), which was translated in this study, and the World Health Organization (WHO) quality of life (WHOQOL) questionnaire by Skevington et al. (2004). In addition, 13 participants were selected to assess the retest reliability, and the reliability of the S-CGQoL was confirmed based on Cronbach's alpha. Results: The results of the conformational factorial analysis indicated significant correlations between the factorial load of all the items in the S-CGQoL with the related factor (P<0.05) with relatively appropriate efficiency indices. Moreover, the results of internal reliability indicated the Cronbach's alpha range of 0.54-0.92 in various sub-indices of the questionnaire. The results of the retest reliability showed that Pearson's correlationcoefficients for all the sub-indices of the S-CGQoL were significant in the two performed stages (P<0.05), with the overall correlation-coefficient of 0.96. In addition, the results of concurrent validity the sub-indices of the SCGQoL with WHOQOL with the correlation-coefficient was 0.56. Therefore, the two scales had a potent, inverse association. Conclusion: According to the results, the Persian version of the S-CGQoL had proper validity and reliability and could be used for the caregivers of patients with schizophrenia in the healthcare centers in Iran.
