Adaptation to Hysterectomy: Design and Psychometric Properties Assessment of Hysterectomy Adaptation Scale.

Background: Adaptation to complications of hysterectomy is one of the topics of concern for women and health care providers. There is no instrument for evaluating adaptation to hysterectomy. This study aimed to design the Hysterectomy Adaptation Scale (HAS) and assess its psychometric properties. Materials and Methods: This methodological study was conducted from 2018 to 2020 in Mashhad, Iran. To develop the item pool, qualitative data from directed content analysis and data from the review of adaptation and coping instruments were used. The face, content, construct validity, internal consistency, and stability were used to evaluate the psychometric properties of HAS. Results: The final version of the HAS consisted of 24 items with a reported content validity index of 0.9. Six factors were extracted from the principal component analysis, which explained 60.3 of the observed variance. Model fit indices in confirmatory factor analysis showed that the model was well fitted. The values of the alpha coefficient and intra-class coefficient were 0.86 and 0.95, respectively. Conclusions: The HAS is a valid and reliable scale for evaluating the adaptation level of hysterectomized Iranian women. HAS can distinguish between hysterectomized women who have adapted to hysterectomy and those who have not. It can be used to assess the adaptation of hysterectomized women in research and clinical practice.
