چکیده

پژوهش حاضر با هدف بررسی ساختار عاملی، پایایی و روایی مقیاس هزینه (CS) انجام گرفته است. این مطالعۀ کاربردی، یک طرح روان‌سنجی است و جامعۀ آماری آن را دانش‌آموزان دختر پایه‌های دهم و یازدهم شهر کاشان در سال تحصیلی 1396-1395 تشکیل می‌دهند. از میان دانش‌آموزان دختر مدارس دولتی، 404 نفر به روش نمونه‌گیری خوشه‌ای چندمرحله‌ای انتخاب شدند و به مقیاس هزینه پاسخ دادند. روایی و پایایی، تحلیل‌عاملی اکتشافی و تأییدی با استفاده از نرم‌افزارهای SPSS و LISREL بررسی شد. نتایج تحلیل‌عاملی اکتشافی با روش مؤلفه‌های اصلی، سه عامل هزینۀ تلاش و هیجان تکلیف، هزینۀ تلاش بیرونی و نبود گزینه‌های جایگزین مهم را برای مقیاس هزینه تأیید کرد. برای بررسی پایایی پرسشنامه از ضریب آلفای کرونباخ و برای تعیین روایی آن از تحلیل‌عاملی استفاده شد. نتایج نشان داد پرسشنامه از همسانی درونی قابل‌قبولی برخوردار است و ضرایب آلفای کرونباخ در زیرمقیاس‌های آن بیشتر از 9/0 است. مطابق نتایج تحلیل‌عاملی تأییدی، ساختار پرسشنامه برازش قابل‌قبولی با داده‌ها دارد و کلیۀ شاخص‌های نیکویی برازش، مدل را تأیید می‌کنند. یافته‌های تحلیل‌عاملی، تقریباً مشابه تحقیقات انجام‌گرفته در فرهنگ اصلی و ضرایب پایایی و روایی نیز به نتایج آن‌ها نزدیک است؛ بنابراین با توجه به خصوصیات روان‌سنجی مطلوب، این پرسشنامه ابزار مناسبی برای تعیین هزینۀ ادراک‌شده در دانش‌آموزان است.

چکیده [English]

The purpose of this study is to investigate the factor structure, reliability, and validity of the cost scale. This applied study adopted a psychometric design and its statistical population consisted of 10th and 11th grade female students in Kashan during the 2016–2017 school year. Among the female students in public schools, 404 were selected through a multistage cluster sampling method and answered the cost scale. Validity and reliability, exploratory and confirmatory factor analysis were evaluated using SPSS and LISREL software. The results of exploratory factor analysis by principal components method confirmed the three factors of task emotional and effort cost, outside effort cost and loss of estimated alternatives for cost scale. To investigate the reliability of the questionnaire, Cronbach’s alpha was used and factor analysis was employed to determine validity. In addition, results indicated that the questionnaire had acceptable internal consistency and the Cronbach’s alpha coefficients in the subscales are above 0.9. The results of the confirmatory factor analysis confirmed that the structure of the questionnaire had an acceptable fit with the data and all the indicators of goodness of fit confirmed the model. The results of the factor analysis were almost identical to those of the original culture and the reliability and validity coefficients were close to their results. Therefore, considering the desirable psychometric properties, this questionnaire is a suitable instrument for determining students’ perceived costs.
