Validation of a Korean Version of Fertility Problem Inventory

SummaryPurposeThe Fertility Problem Inventory (FPI) is a screening instrument used to identify infertility-related stress. The purpose of this study was to assess the reliability and validity of the Korean version of the FPI.MethodsForward–backward translation of the FPI from English to Korean was conducted. The translated instrument was pilot-tested and administered to 259 women with infertility. Test-retest reliability was conducted and the internal consistency coefficient was determined. Validity was evaluated through content validity, construct validity with confirmatory factor analysis, discriminant validity, and convergent validity.ResultsThe internal consistency was satisfactory (Cronbach's alpha = .92, item-total correlations = .60–.92). The overall content validity index was 96.9%, signifying that the FPI had good content validity. The model fit indexes were acceptable (goodness of fit index = .92, adjusted goodness of fit index = .91, normal fit index = .95, comparative fit index = .93, and root mean square error of approximation = .05), indicating good construct validity. The intercorrelations were significant, although low to moderate in size (.20–.59). The correlation between the FPI and depression ranged from .32 to .51 (p < .001), while the correlation between the FPI and the fertility-related quality of life ranged from –.35 to –.58 (p < .001).ConclusionThe Korean version of the FPI has high reliability, and good content, construct, discriminant, and convergent validity. A validated Korean version of the FPI may help nurses identify infertility-related stress and administer appropriate nursing interventions to Korean women with infertility.
