The Turkish version of the Postpartum Bonding Questionnaire (PBQ): Examination of the validity and reliability and scale structure.

PURPOSE: The aim of this study is to investigate the validity and reliability of the Turkish version of the Postpartum Bonding Questionnaire (PBQ).

DESIGN AND METHODS: This methodological study was conducted with 250 women who presented to three family health centers in Istanbul/Turkey between April and June 2022 and met the sampling criteria. Validity analysis was performed using the content validity index, exploratory factor analysis, and confirmatory factor analysis. Pearson product-moment correlation and Cronbach Alpha reliability coefficients were used for reliability analysis.

RESULTS: To evaluate invariance of the instrument over time, test-retest measurements were conducted at least two weeks apart and showed no difference in mean scores (p > .05). Adjusted goodness-of-fit index >0.97 and comparative fit index >0.98 confirmed the construct validity of the Turkish PBQ. Each item had a content validity index of 96%. Corrected item-total score correlations ranged from 0.50 to 0.93. The Cronbach Alpha was found to be 0.96, indicating high internal consistency.

CONCLUSION: The results of this study show that the Turkish version of the PBQ is valid and reliable. It can be used as a measurement tool to determine the degree of maternal bonding in the postpartum period.
