Investigating the Psychometric Properties (validity and reliability) of the Harter children's self-perception profile

مطالعه حاضر با هدف بررسي ويژگي­ هاي روانسنجي پرسشنامه خود-ادراكي كودكان هارتر (1985) انجام گرفت. اين پژوهش يك مطالعه از نوع روانسنجي بود. نمونه شامل 400 دانش آموز (200 نفر دختر و 200 نفر پسر) بودند كه با روش نمونه گيري تصادفي ساده انتخاب شدند و پرسشنامه خود-ادراكي هارتر (1985)، پرسشنامه عزت نفس كوپر اسميت (1967) و پرسشنامه روابط مياني دلبستگي كاپنبرگ و هالپرن (2006) را تكميل كردند. نتايج تحليل عاملي اكتشافي وجود پنج عامل را نشان داد كه در مجموع 962/ 57 درصد از از واريانس كل مقياس را تبيين كردند. نتايج تحليل عاملي تاييدي نتايج حاصل از تحليل عاملي اكتشافي را تاييد كرد.ضريب پايايي كلي پرسشنامه به روش آلفاي كرونباخ 87/0 و به روش آزمون-بازآزمون 89/0 به دست آمد. هم­چنين ارتباط مثبت معنادار عامل­هاي اين مقياس با عزت نفس و سبك دلبستگي ايمن تكامل انطباقي مثبت روايي همگراي مقياس و ارتباط منفي عامل ­هاي پرسشنامه خود-ادراكي كودكان هارتر با سبك­هاي دلبستگي ناايمن واكنش هيجاني، رفتارهاي منفي و دوري گزيدن روايي واگراي مقياس را تاييد كرد. نتايج مطالعه نشان داد كه پرسشنامه خود-ادراكي كودكان هارتر ويژگي هاي روانسنجي مناسبي جهت اندازه ­گيري خود-پنداره كودكان دارد.
