The Perimenopausal Fatigue Self-Management Scale Is Suitable for Evaluating Perimenopausal Taiwanese Women’s Vulnerability to Fatigue Syndrome

The purpose of this study was to test the feasibility of utilizing the established perimenopausal fatigue self-management scale (P-MFSMS) to evaluate perimenopausal Taiwanese women’s vulnerability to fatigue syndrome. A cross-sectional study design was adopted to survey 220 perimenopausal Taiwanese women with a mean age of 51.8 ± 4.64 years and a mean body mass index of 23.07 ± 3.04 kg/m2, 75.9% of whom were married, 52.3% had a college education or above, 80.4% had salaries, 81.3% had small families, and 96.4% were not using hormone therapy. The P-MFSMS consists of 25 questions based on six categories: (1) strive to maintain work energy and efficiency; (2) seek self-help from medical resources (doctor shopping); (3) strive to maintain the normal operation of the family (seeking help and support from family or significant other); (4) make time for activities or exercise in busy life; (5) slow down or adjust lifestyle; (6) frustration. For all of these six categories, the minimum loading of each question on the factor was calculated to be over 0.50, with a Cronbach’s α of 0.78 and a corrected total-item correlation of >0.50. The goodness of fit of the model was determined to be acceptable, with a chi-square/df value of <3.0 (χ2 = 503.45 and df = 260), a root mean square error of approximation (RMSEA) value of 0.065 (<0.08), as well as a Kaiser–Meyer–Olkin (KMO) value of 0.892. The Tucker–Lewis index (TLI = 0.91), Comparative Fit index (CFI = 0.92), and Incremental Fit index (IFI = 0.92) were all >0.90. There was no statistically significant difference in the difficulty between perimenopausal and postmenopausal women utilizing differential item function (DIF) analysis. Taken together, the 25-question P-MFSMS may be a potentially valid and reliable instrument for suitably evaluating perimenopausal Taiwanese women’s vulnerability to fatigue syndrome. Future studies will be conducted to test the effectiveness of the P-MFSMS for evaluating perimenopausal Taiwanese women’s vulnerability to fatigue syndrome in clinical practice.
