BACKGROUND: To date there has been no study investigating mother-infant bonding impairment and its link to pospartum depressive symptoms in a representative German population sample. The present study therefore aimed to carry out initial analyses of the psychometric properties of the German version of the Postpartum Bonding Questionnaire (PBQ). METHODS: Eight hundred and sixty two mothers provided the data for a principal component analysis of the original 25 item PBQ. This analysis was used to assess the validity of the four scale structure of the questionnaire. Correlations between postpartum depression, sociodemographic variables and bonding impairment were additionally calculated. FINDINGS: On the basis of our data, the original 4 factor structure of the PBQ scale was not confirmed. Nine items did not meaningfully load onto the single factor accounting for the most variance. Mother-infant bonding impairment and postpartum depression were shown to be significantly positively correlated. According to the factor solution of Brockington we found a 7.1% rate of mothers with bonding impairment two weeks postpartum (with 95% confidence ranging from 5.5 to 9%). INTERPRETATION: An abridged 16 item German version of the PBQ can be implemented as a reliable screening instrument for bonding impairment.
