Highlights
- •This is the first methodological study to validate the psychometric characteristics of the Perinatal Posttraumatic Stress Disorder Questionnaire (PPQ) among Chinese mothers.
- •The Chinese version of the PPQ (PPQ-C) is a reliable and valid measure of perinatal posttraumatic stress disorder (PPTSD) symptoms in a Chinese context.
- •The PPQ-C has the potential to be used as a screening tool for earlier recognition and treatment of PPTSD symptoms among mothers in the Chinese population, especially those at high risk.
Abstract
Background
Perinatal posttraumatic stress disorder (PPTSD) is a common stress-induced mental
disorder worldwide. The Perinatal Posttraumatic Stress Disorder Questionnaire (PPQ)
is an excellent questionnaire that measures the symptoms of PPTSD, but has not been
translated into Chinese yet.
Objectives
The aims of this study were to develop a translated Chinese version of the (PPQ) and
validate the psychometric characteristics of the PPQ in a Chinese context.
Methods
After translation, back-translation, and expert discussion, 280 mothers at 1 to 18 months postpartum filled out the questionnaires through the Internet. Then the reliability
and validity of the translated questionnaire were tested.
Results
The Chinese version of PPQ (PPQ-C) was composed of 14 items. Cronbach's α coefficient was 0.84, test-retest reliability was 0.88, and the content validity
was 0.99. Exploratory factor analysis extracted three factors (representing “arousal”,
“avoidance” and “intrusion”) accounted for 53.30% of the variance. The established
3 factors model was well fitted with the collected data (χ2 = 76.40, p < 0.05).
Implications for practice
The PPQ-C is a short, reliable, and valid instrument that measures the symptoms of
PPTSD, and it is recommend for clinical screening.
Implications for research
Further research could involve diverse participants, as well as better adapt the PPQ-C
to Chinese culture.
