Impairment of mother-infant relationship: Validation of the Chinese version of postpartum bonding questionnaire

Abstract

The implementation of the Comprehensive Child Development Service in Hong Kong brought about the need for the development of an instrument for assessing mother-infant relationship impairments in women with postnatal depression. The Postpartum Bonding Questionnaire by was first translated into Chinese, then back-translated into English. An expert panel was set up to evaluate the content validity and a focus group discussion was held to explore the face validity and acceptability of the questionnaire. The Chinese version of the Postpartum Bonding Questionnaire (C-PBQ) was administered to 62 women suffering from postnatal depression. Scale 1 of the C-PBQ had a sensitivity of 84% for detecting women with any forms of mother-infant relationship impairments and scale 2 had a sensitivity of 89% for detecting rejection of infant and a sensitivity of 77% for detecting pathological anger towards infant. The C-PBQ is a useful instrument for detecting mother-infant relationship impairments as perceived by women with postnatal depression. © 2010 by Lippincott Williams & Wilkins.
