چکیده

هدف: هدف پژوهش حاضر بررسی ویژگی‌های روان سنجی مقیاس استرس آسیب‌زا کوید-19 بود که اثرات ویروس کرونا را بر جنبه‌های مختلف زندگی مردم ایران مورد بررسی قرار می‌دهد. روش:پژوهش حاضر توصیفی از نوع همبستگی بود. جامعۀ آماری شامل کلیۀ افرد بزرگسال شهر تهران در دامنۀ سنی 17 تا 72 سال بود. 461 نفر از طریق فراخوانی اینترنتی در تحقیق شرکت کردند. برای تجزیه‌وتحلیل داده‌ها از دو روی‌آورد کلاسیک و نظریۀ سؤال- پاسخ و از نرم­افزارهای آماری Spss نسخۀ 26 و نرم افزار R نسخۀ 4.0.1 استفاده شد. یافته‌ها: نتایج بررسی روایی سازه ابزار با روش تحلیل عاملی اکتشافی و تأییی )نظریه کلاسیک (و مدل‌های چندبعدی )نظریۀ سؤال پاسخ (، سه عامل مربوط به مقیاس استرس آسیب‌زا کوید-19 را تأیید کرد. همچنین روایی ملاکی، همگرا و واگرای ابزار نیز مورد تأیی قرار‌گرفت. اعتبار مقیاس نیز با روش آلفای‌کرونباخ (مقادیر آلفای بالای 70/0 برای هر سه عامل و نمره کل) و روش باز‌آزمایی (همبستگی درون طبقه ای بالا بین دو مرحله اندازه گیری) در روی آورد کلاسیک آزمون تأیی شد. براساس نظریۀ سؤال پاسخ نیز اعتبار داده‌ها با استفاده از تابع آگاهی و خطای اندازه‌گیری بررسی شد که تابع ‌آگاهی مقیاس نشان داد که هر سه عامل در محدودۀ سطح صفت بین 2- تا 2، بیشترین آگاهی­دهندگی و کمترین خطای اندازه­گیری داشتند (01/0> p). نتیجه گیری: مقیاس استرس آسیب‌زای کوید-19 از اعتبار و روایی مطلوبی در جامعۀ ایرانی برخوردار است و می‌توان از آن به عنوان یک ابزار علمی معتبر برای ارزیابی اثرات ویروس کرونا بر جنبه‌های مختلف زندگی مردم ایران استفاده کرد.

چکیده [English]

Aim: The purpose of this study was to investigate the psychometric properties of the Covid-19 traumatic stress scale Which examines the effects of the corona virus on various aspects of Iranian life. Method: The present study was a descriptive correlational study. The statistical population included all adults in Tehran in the age range of 17 to 72 years. 461 people participated in the study through an online call. To analyze the data, Classical Test Theory and Item Response Theory were used and statistical software Spss version 26 and R software version 4.0.1 were used. Results: The results of the instrument validity study using exploratory and confirmatory factor analysis (classical theory) and multidimensional models (Item Response Theory) confirmed three factors related to the Covid-19 traumatic stress Scale. convergent and divergent validity of the instrument was also confirmed. The validity of the scale was confirmed by Cronbach's alpha method (alpha values above 0.70 for all three factors and the total score) and the retest method (high intra-class correlation between the two measurement steps) in the classical approach of the test. Based Item Response Theory, the validity of the data was assessed using the Information function and measurement error. The Information function showed that all three factors in the trait level range between 2- to 2 had the highest awareness and the least measurement error (p <0.05). Conclusion: The Covid-19 traumatic stress scale has good validity and reliability in Iranian society and can be used as a valid scientific tool to assess the effects of the Corona virus on various aspects of Iranian life.
