Oh and Kim: Validity and Reliability of a Korean version of Polycystic Ovary Syndrome Questionnaire



Polycystic Ovary Syndrome Questionnaire (PCOSQ) was developed to measure health-related quality of life of women who had polycystic ovary syndrome. The purpose of this study was to exam reliability and validity of the Korean version of PCOSQ.


sample of 101 women who had polycystic ovarian syndrome was recruited from outpatient gynecology clinics. Factor analysis was carried out to verify the composition of dimensions of the Korean version of PCOSQ. Concurrent validity was examined by assessing the correlation between the PCOSQ and health related quality of life, and convergent validity was evaluated by testing correlation between PCOSQ and depression. Reliability was assessed using Cronbach's α.


The content validity was satisfactory (CVI=0.85). Factor analysis identified 5 factors, and factor loadings of the PCOSQ ranged from .48 to .90. Correlation was found between the PCOSQ and health related quality of life (Physical component score: r=.33, p=.001; Mental component score: r=.44, p<.001) and between the PCOSQ and depression (r=-.36, p<.001). The Cronbach's α of the PCOSQ was .93, indicating reliable reliability.


These results demonstrate that the Korean version of PCOSQ is a reliable and valid instrument for evaluating Korean-speaking women with polycystic ovarian syndrome.

Summary Statement

▪ What is already known about this topic?
Women with polycystic ovary syndrome (PCOS) have a lower quality of life than do healthy women. A measure of the quality of life of women with PCOS was developed. Its reliability and validity have been verified in many studies.
▪ What this paper adds?
It was confirmed that the Korean version of the PCOS questionnaire has high reliability and good content, construct, concurrent, and convergent validity.
▪ Implications for practice, education and/or policy
A validated Korean version of the PCOS questionnaire may help nurses identify the specific needs of patients with PCOS and develop appropriate nursing interventions for Korean women with PCOS.
