The purpose of this study was to develop the Japanese version of the Postpartum Bonding Questionnaire (PBQ) to gather data on Japanese mothers for comparison with other cultures and to examine the scale structure of the PBQ among Japanese mothers.
We administered the PBQ to a cross-section of 244 mothers 4 weeks after delivery and again 2 weeks later to 199 mothers as a retest to examine reliability. We used exploratory factor analysis to evaluate the factor structure of the PBQ. Correlations with the Mother-to-Infant Bonding Scale (MIBS), the Maternal Attachment Inventory (MAI), Edinburgh Postnatal Depression Scale (EPDS), and sociodemographic variables were calculated for validation.
The 14-item version of the PBQ extracted by exploratory analysis consisted of four factors: 'impaired bonding', 'rejection and anger', 'anxiety about care', and 'lack of affection'. We found significant correlations of the total scores of the PBQ and the 14-item version of the PBQ positively with the MIBS and negatively with the MAI. Moderate significant correlations with total scores were also found with the EPDS. Total scores for primiparous and depressed mothers were higher than those for multiparous mothers and mothers without depression.
The results of this study demonstrated the reliability and validity of the PBQ and the 14-item version of the PBQ in Japanese mothers 4 weeks after delivery.
本研究旨在开发产后亲密关系问卷（PBQ）的日语版本，以收集日本母亲的数据，用于与其他文化进行比较，并检验日本母亲中PBQ的量表结构。
我们在分娩后4周对244名母亲进行了PBQ问卷调查，并在2周后对199名母亲进行了重测，以检验可靠性。我们使用探索性因素分析来评估PBQ的因素结构。计算PBQ与母婴亲密关系量表（MIBS）、母亲依恋量表（MAI）、爱丁堡产后抑郁量表（EPDS）以及社会人口统计学变量之间的相关性以进行效度验证。
通过探索性分析提取的14项版PBQ由四个因素组成：“亲密关系受损”、“拒绝与愤怒”、“护理焦虑”和“缺乏情感”。我们发现PBQ总分及14项版PBQ总分与MIBS呈显著正相关，与MAI呈显著负相关。PBQ总分与EPDS也存在中度显著相关性。初产妇和抑郁母亲的总分高于经产妇和非抑郁母亲。
本研究结果证明了PBQ及14项版PBQ在产后4周的日本母亲中的可靠性和有效性。
