Background:
Research on body image in women with polycystic ovary syndrome (PCOS) has increased due to its significant physical and psychological impact.The aim of this study was to develop and validate the Polycystic Ovary Syndrome Body Image Scale (PCOSBIS).
Design:
An instrument development and validation study was completed in the following three phases: (Ⅰ) the generation and revision of the item, (Ⅱ) the preliminary reduction of items and construct validation (Ⅲ) the psychometric evaluation of the scale.
Methods:
Data were collected from April to September in 2024. An item pool was generated through literature review, Delphi expert consultation, and interviews with 21 PCOS patients. The instrument-verification phase surveyed 400 PCOS patients from three tertiary general hospitals. Exploratory factor analysis and confirmatory factor analysis were conducted, and criterion validity, internal consistency, and test-retest reliability were assessed.
Results:
The PCOSBIS was comprised six dimensions with 23 items, accounting for 70.79 % of the variance. Confirmatory factor analysis showed a good model fit. PCOSBIS exhibited strong reliability (α = 0.92) and test-retest stability. As expected, the PCOSBIS is positively correlated with the Connor-Davidson Resilience Scale (CD-RISC) and Medical Outcomes Study Short-Form 36-Item Health Survey (SF-36). Analysis of 400 patients' score revealed a mean score of 48.60 ± 10.85, with the lowest score in 'Physiological Function Satisfaction.'
Conclusion:
PCOSBIS exhibits robust psychometric properties, making it a valuable tool for assessing body image disturbances in PCOS patients.
