The Validity and Reliability of the Postpartum Symptom Inventory in Turkish Women

Abstract

Objective: Postpartum period is a significant period that covers approximately 6 weeks after childbirth, progresses with various symptoms, and affects the life of the woman. The study was conducted in order to test the validity and reliability of the Postpartum Symptom Inventory (PSI-20). 
 Methods: The study was conducted on 310 participants with a descriptive, cross-sectional, and methodological design. The study data were collected through Identifying Information Form, Postpartum Symptom Inventory, and Edinburgh Postnatal Depression Scale as a parallel form. In the analysis of the data, factor analysis, Cronbach’s alpha coefficient, and item-total score correlations were used. 
 Results: The scale consisted of 20 items under 6 subscales with a variance of 71%. The Cronbach’s alpha coefficient of the Turkish version of the scale was 0.86. According to split-half test reliability, Cronbach’s alpha coefficients of the first and second halves were found to be 0.71 and 0.73, respectively, Guttman split-half coefficient was 0.94, and the correlation coefficient between the halves was determined as 0.88. According to confirmatory factor analysis, Root Mean Square Error of Approximation Index (RMSEA) 0.072, Goodness of Fit index (GFI) value was 0.89, Comparative Fit Index (CFI) value was 0.94, Relative Fit Index (RFI) was 0.89, Incremental Fit Index (IFI) was 0.94, and Tucker-Lewis index (TLI) value was found as 0.93. 
 Conclusion: As a result of the study, it was determined that the Turkish version of the Postpartum Symptom Inventory (PSI-20) was a valid and reliable tool in order to measure postpartum symptoms in Turkish women.
