Hebrew validation of the postpartum bonding questionnaire: a study of mothers and fathers

ABSTRACT

Objective

The Postpartum Bonding Questionnaire (PBQ) is a self-report questionnaire designed to screen disorders of the mother–infant relationship. The PBQ was adapted to several countries, though there is no agreement on the accepted number of items and factors. This study aimed to assess the validity and reliability of the Hebrew version for both mothers and fathers.

Methods

Participants (602 mothers and 144 fathers) from two separate samples were randomly recruited in the maternity ward of a large tertiary health centre. The mothers’ samples were combined and redivided to form subsamples A and B. At T1 (1–4 days postpartum), the participants completed demographic questionnaire in person the PBQ and the Edinburgh Postpartum Depression Scale (EPDS) were administered online at T2 (8–12 weeks postpartum). The PBQ was also administrated at T3 (six-months).

Results

EFA on subsample A resulted in a two-factor structure, which was tested using CFA on subsample B. The model’s fit was very good; χ(35)² = 83.68, p < .001, CFI = .97, TLI = .91, RMSEA = .07, SRMR = .03. Additional reliability and validity analyses showed a very good fit for mothers. Scalar measurement invariance across mothers and fathers yielded satisfactory results. CFA among fathers, revealed adequate goodness of fit; χ²/df = 87.65/46, p < .001, CFI = .95, TLI = .89, RMSEA = .08, SRMR = .05.

Conclusions

The Hebrew version of the PBQ demonstrated satisfactory validity for both mothers and fathers. The revised version, with 14 items, measures bonding as a continuum rather than measuring bonding disorders like the original version. These findings emphasise the importance of validating the scale in different cultural contexts.
