A review of the psychometric properties and implications for the use of the fertility quality of life tool
Abstract
Abstract Objectives To analyze and synthesize the reported psychometric properties of the Fertility Quality of Life (FertiQoL) instrument and describe its implications for use in practice and research in men and women with infertility. Methods A systematic literature search was performed to identify all articles using the FertiQoL tool. PubMed, CINAHL, and PsycINFO were searched from September 2006 through May 2022. Studies were eligible for inclusion if they reported psychometric data on the original FertiQoL tool using a sample population of individuals with infertility. Sample size, country of origin, and psychometric data were documented for each study. Results The initial search revealed 153 articles that had utilized the FertiQoL. Following abstract, title, and full-text screenings, 53 articles reported psychometric data and met criteria for inclusion. The FertiQoL is a sound measurement with satisfactory reliability and validity. Studies indicated adequate reliability in the overall scale ( $$\alpha=0.43-0.92$$ α = 0.43 - 0.92 ), as well as the core Emotional, Mind/Body, Social, and Relational scales ( $$\alpha=0.43-0.92$$ α = 0.43 - 0.92 ) and two optional Tolerability and Environment fertility treatment subscales ( $$\alpha=0.67-0.91$$ α = 0.67 - 0.91 ). Although the Relational subscale exhibited slightly lower reliability in several studies, the internal consistency for the measurement as a whole was satisfactory. Results also indicate adequate: 1) face and content validity with extensive professional and patient feedback during development; 2) convergent validity with general quality of life, depression, and anxiety measurements; and 3) structural validity using both confirmatory and exploratory factor analyses. Conclusion The FertiQoL tool is the most commonly used instrument to measure the impact of fertility issues on quality of life in men and women with infertility. Understanding the impact of infertility on quality of life provides valuable insight into the areas of infertility-related care that need to be prioritized, such as mental health or relational stressors. While the instrument has been used in different patient populations with infertility and available in multiple translations, it is necessary to understand the updated psychometric properties and the implications for its use. This review shows that the FertiQoL is reliable and valid for cross-cultural use among individuals with various etiologies of infertility.
