ويژگي‌هاي روان‌سنجي مقياس آمادگي به نوستالژي در دانشجويان دانشگاه علوم پزشكي اصفهان در سال 1394

Psychometric Characteristics of Nostalgia-Proneness in Students of Isfahan University of Medical Sciences in 2015

زمينه و هدف: آمادگي به نوستالژي (Nostalgia-Proneness) خوشي مشتاقانه و يك شادي آميخته با ناراحتي تعريف شده است. دانشجويان به دلايلي از قبيل آشنا نبودن با محيط دانشگاه يا فرهنگ حاكم بر منطقه در صورت غير بومي‌بودن و يا جدايي و دوري از خانواده، در شرايطي هستند كه «احساس غربت» را كه در ارتباط با نوستالژي مي‌باشد تجربه مي‌كنند. بنابراين به دليل نقش نوستالژي در حيطه‌هاي فردي و بين فردي و سلامت روان، سنجش اين متغير در دانشجويان حائز اهميت است. هدف پژوهش حاضر بررسي روايي و پايايي نسخه فارسي مقياس آمادگي به نوستالژي در دانشجويان علوم پزشكي بود. مواد و روش‌ها: اين تحقيق از نوع مقطعي و اعتبارسنجي بود كه در سال 1394 بر روي نمونه‌اي متشكل از 203 نفر از دانشجويان دانشگاه علوم پزشكي اصفهان انجام گرديد. انتخاب نمونه به‌صورت در دسترس بود. پس از بررسي روايي محتوايي مقياس آمادگي به نوستالژي، از همبستگي نمره‌ها با نمره كل و همبستگي خرده مقياس‌ها استفاده شد. براي تعيين ساختار عاملي مقياس، تحليل عاملي اكتشافي مورد استفاده قرار گرفت. براي تعيين همساني دروني، از ضريب آلفاي كرونباخ و براي تعيين پايايي از روش بازآزمايي استفاده شد. يافته‌ها: همبستگي گويه‌ها با نمره كل بين 0/20 تا 0/60 و معني‌دار بود (0/001

Background and Objective: Nostalgia-Proneness is defined as a state of eager joy and happiness mixed with sadness. Students who are non-native to a region and are away from their families tend to experience a sense of "homesickness" that is associated with nostalgia for several reasons such as being unfamiliar with the university environment or the culture of the region. Therefore, given the role of nostalgia in the personal, interpersonal and mental health, it is essential to measure this variable among college students. The aim of this study was to examine the validity and reliability of the Nostalgia-Proneness scale in the students of Isfahan University of Medical Sciences. Materials and Methods: The present study was a cross-sectional validation research effort. It was conducted in 2015 on a group of 203 of medical students in Isfahan University of Medical Sciences who were selected through convenient sampling. After investigating content validity of Nostalgia-Proneness scale, the correlations between the scores and the overall score and the subscales were used. Furthermore, exploratory factor analysis was performed to determine the factor structure of the scale. Finally, internal consistency and reliability were established via Cronbach’s alpha coefficient and test-retest, respectively. Results: Item-score correlations varied from 0.20 to 0.60 and were significant (p<0.001). Exploratory factor analysis confirmed the scale as having four factors: (1) Personal nostalgia; (2) Interpersonal nostalgia; (3) Cultural nostalgia; and (4) Virtual nostalgia. In total, factor loadings explained 63.24 percent of variance of total items. Cronbach’s alpha coefficient was 0.83 while the half-split reliability coefficient was equal to 0.75. Conclusion: The results indicated the instrument enjoys sufficient reliability and validity among students. Therefore, the scale can be used in students of medical sciences.
