بررسي ويژگي هاي روان سنجي فرم كوتاه مقياس خودكارآمدي تصميم گيري شغلي

The study of the psychometric characteristics Career decision Self- Efficacy Scale Short Form

خودكارآمدي ، يكي از سازه هاي مهم در نظريه ي شناختي- اجتماعي بندورا است و به معني اطمينان و باور فرد نسبت به توانايي هاي خود در كنترل افكار، احساس ها، فعاليت ها و نيز عملكرد موثر او در موقعيت هاي استرس زاست. اين پژوهش با هدف بررسي ساختار عاملي و ويژگي هاي روان سنجي(روايي و پايايي) مقياس كوتاه خودكارآمدي تصميم گيري شغلي ميان دانشجويان اجرا شد. روش پژوهش همبستگي(سنجش روايي و پايايي) و جامعه آماري پژوهش شامل دانشجويان دانشگاه تهران در سال تحصيلي 96-95 بود كه از ميان آنها 367 نفر به شيوه نمونه گيري تصادفي خوشه اي انتخاب شدند. ابزار پژوهش شامل مقياس خودكارآمدي تصميم گيري شغلي بود. به منظور بررسي روايي مقياس، تحليل عاملي تاييدي(GFE) انجام شد. نتايج نشان داد كه شاخص برازش مقياس در وضعيت مطلوبي قرار دارد و ضريب پايايي مقياس به روش آلفاي كرونباخ، برابر 0/88 به دست آمد. بر اساس نتايج، مقياس خودكارآمدي تصميمي گيري شغلي در جامعه دانشجويان دانشگاه تهران داراي روايي و پايايي مناسبي است.

Self-efficacy is one of the important structures in Bandura's cognitive-social theory and it means the individual's confidence and belief in his ability to control his thoughts, feelings, activities, and his effective performance in stress situations.The purpose of the present study was to examine factor structure and psychometric properties of the Career decision Self- Efficacy Scale Short Form among the students. The research method was correlation (validity and reliability measurement) and the statistical population consisted of students university of Tehran in the academic year of 2016-2017, from which a sample of 367 students were selected by cluster random sampling. Measuring instruments were the Career decision Self- Efficacy scales. To investigate the validity aspect of Career decision Self- Efficacy scales confirmatory factor analysis technique (CFA) was used. The results showed that the model parameters are fit. The scale reliability coefficient, and internal consistency using Cronbach's alpha was 0.88. According to the results, the Career decision Self- Efficacy scales, in the community students university of Tehran, has good reliability and validity.
