Purpose: The Perinatal Post-Traumatic Stress Disorder Questionnaire<br />(PPQ) was designed to measure post-traumatic symptoms related to<br />childbirth and symptoms during postnatal period. The purpose of this<br />study was to develop a translated Korean version of the PPQ and to<br />evaluate reliability and validity of the Korean PPQ. Methods:<br />Participants were 196 mothers at one to 18 months after giving<br />childbirth and data were collected through e-mails. The PPQ was<br />translated into Korean using translation guideline from World Health<br />Organization. For this study Cronbach's alpha and split-half reliability<br />were used to evaluate the reliability of the PPQ. Exploratory Factor<br />Analysis (EFA), Confirmatory Factor Analysis (CFA), and known-group<br />validity were conducted to examine construct validity. Correlations of<br />the PPQ with Impact of Event Scale (IES), Beck Depression Inventory II<br />(BDI-II), and Beck Anxiety Inventory (BAI) were used to test a criterion<br />validity of the PPQ. Results: Cronbach's alpha and Spearman-Brown<br />split-half correlation coefficient were 0.91 and 0.77, respectively. EFA<br />identified a 3-factor solution including arousal, avoidance, and<br />intrusion factors and CFA revealed the strongest support for the<br />3-factor model. The correlations of the PPQ with IES, BDI-II; and BAI<br />were .99, .60, and .72, respectively, pointing to criterion validity of<br />a high level. Conclusion: The Korean version PPQ is a useful tool for<br />screening and assessing mothers' experiencing emotional distress related<br />to child birth and during the postnatal period. The PPQ also reflects<br />Post Traumatic Stress Disorder's diagnostic standards well.
