چکیده

مقدمه: شدت­ علائم­ یائسگی­ در زنان ­بسیار متفاوت ­است­ و علاوه بر اثراتی که روی فرآیند پیری دارد، تغییرات هورمونی با تحریک علائم می‌­تواند در کیفیت زندگی زنان تأثیر بگذارد. ابزارهای متعددی به‌منظور ارزیابی تغییرات جسمی و روان‌شناختی در دوران یائسگی وجود دارد. پرسشنامه MSSI-38 یکی از ابزارهای نوین برای ارزیابی همزمان فراوانی و شدت علائم دوران یائسگی با مقیاس پنج درجه­ای لیکرت می­باشد. مطالعه حاضر با هدف تعیین روایی و پایایی پرسشنامه MSSI-38 انجام شد.
روش‌کار: این مطالعه مقطعی در سال 1396 بر روی 676 زن ایرانی ساکن شهر مشهد انجام گرفت. پرسشنامه MSSI-38 به فارسی ترجمه و پس از محاسبه CVR، 6 گویه بر اساس معیار جدول لاوشه حذف شد و با انجام تحلیل عاملی اکتشافی، 9 عامل استخراج گردید. روایی محتوا با شاخص­های ضریب نسبی روایی محتوا (CVR) و شاخص روایی محتوا (CVI) و روایی ساختار با شاخص­های میانگین واریانس استخراج شده (AVE) و روایی ترکیبی (CR) ارزیابی شد. تجزیه و تحلیل داده‌ها با استفاده از نرم‏افزار SPSS (نسخه 16) و MPlus وSmart PLS انجام شد. میزان p کمتر از 05/0 معنادار در نظر گرفته شد.
یافته­ها: مقدار AVE (56/0=AVE) در حد مطلوب بود. مقدار 87/0=CVI به‌دست آمد و روایی محتوای مقیاس تأیید شد. مقادیر نمره آلفای کرونباخ و روایی ترکیبی در اکثر عامل­ها در حد قابل قبول (بزرگ‌تر از 7/0) بود. مقدار KMO (851/0=KMO)، حاکی از کفایت نمونه مورد بررسی ­بود. پس از تحلیل عاملی تأییدی شاخص­های نکویی برازش مقادیر (968/0=TLI، 972/0=CFI، 039/0=RMSEA،53/1= ) به دست آمد. به کمک تحلیل عاملی تأییدی، 7 عامل استخراج شد و روایی ساختار عامل­ها در پرسشنامه تأیید گردید.
نتیجه­گیری: پرسشنامه MSSI-38 ابزاری ­روا و پایا برای­ ارزیابی شدت علائم یائسگی است و می‌تواند در مطالعات تحقیقی جمعیت ایرانی فارسی زبان مورد استفاده قرار گیرد.

چکیده [English]

Introduction: Menopause symptoms severity is different in women, and in addition to the effects on aging process, hormonal changes with inducing the symptoms can affect women's quality of life. There are several tools to assess physical and psychological changes during the climacteric period. The MSSI-38 questioner is one of the new tools for simultaneous assessment of the frequency and intensity of symptoms with five-point Likert scale. This study was performed with aim to assess the validity and reliability of MSSI-38 questionnaire.
Methods: This cross-sectional study was performed on 676 Iranian women who were resident in Mashhad in 2017. The MSSI-38 questioner was translated into Persian and after calcuating CVR, 6 items were eliminated according to the Lawshe formula and 9 factors were extracted by exploratory factor analyses. The content validity was evaluated with Content Validity Ratio (CVR) and Content Validity Index (CVI), and Construct validity was evaluated with Average Variance Extracted (AVE) and Composite Reliability (CR). Data were analyzed with SPSS software (version 16.0) and MPlus and Smart PLS. P< 0.05 was considered statistically significant.
Results: The value of AVE=0.562 was favorable. The CVI=0.87 was obtained and the content reliability was confirmed. The Cronbach alpha and CR in most of the factors were acceptable (>0.7). KMO=0.851 indicates the adequacy of the samples. After CFA, the goodness of fit indices were (χ2/df=1.53, RMSEA=0.039, CFI=0.972, TLI=0.968). 7 factors were extracted by using CFA and WLSM and factors construct validity was confirmed.
Conclusion: MSSI-38 is a valid and reliable tool for evaluation of Menopause Severity Symptoms and can be used in research articles on Iranian Persian languages population.
