Abstract

Purpose: The Perinatal Post-Traumatic Stress Disorder Questionnaire (PPQ) was designed to measure post-traumatic symptoms relatedto childbirth and symptoms during postnatal period. The purpose of this study was to develop a translated Korean version ofthe PPQ and to evaluate reliability and validity of the Korean PPQ.

Methods: Participants were 196 mothers at one to 18 months aftergiving childbirth and data were collected through e-mails. The PPQ was translated into Korean using translation guideline fromWorld Health Organization. For this study Cronbach¡¯s alpha and split-half reliability were used to evaluate the reliability of the PPQ. Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA), and known-group validity were conducted to examine constructvalidity. Correlations of the PPQ with Impact of Event Scale (IES), Beck Depression Inventory II (BDI-II), and Beck Anxiety Inventory(BAI) were used to test a criterion validity of the PPQ.

Results: Cronbach¡¯s alpha and Spearman-Brown split-half correlationcoefficient were 0.91 and 0.77, respectively. EFA identified a 3-factor solution including arousal, avoidance, and intrusion factorsand CFA revealed the strongest support for the 3-factor model. The correlations of the PPQ with IES, BDI-II, and BAI were .99, .60,and .72, respectively, pointing to criterion validity of a high level.

Conclusion: The Korean version PPQ is a useful tool for screeningand assessing mothers¡¯ experiencing emotional distress related to child birth and during the postnatal period. The PPQ also reflectsPost Traumatic Stress Disorder¡¯s diagnostic standards well.
