Perinatal Post Traumatic Stress Disorder Questionnaire-II (PPQ-II): adaptation, validity, and reliability study

Objective: The aim of this study is to adapt the Perinatal Post Traumatic Stress Disorder Questionnaire-II (PPQ-II) and determine the psychometric properties of this scale. Method: The study was conducted with two different samples consisting of mothers who give full-term and preterm birth. To investigate the factor structure and conduct confirmatory factor analysis, the first sample was composed of 194 women between the ages of 18-43 (Mean=30.12, standard deviation [SD]=4.96). The second sample in which confirmatory factor analysis was conducted consisted of 238 women between the ages of 19-43 (Mean=30.33, SD=4.00). Depression Anxiety Stress Scale and Connor-Davidson Resilience Scale were used in this study as well as PPQ-II. Results: The exploratory and confirmatory factor analysis revealed a two-factor structure named "Intrusive Thoughts and Avoidance" and "Hyperarousal and Numbness Responses". The model obtained by confirmatory factor analysis demonstrated acceptable goodness of fit values and the questionnaire was found to have satisfactory reliability and validity values. Conclusion: PPQ-II could be considered as a valid and reliable scale which could be used in maternal mental health studies conducted in Turkey.
