This study aimed to examine relationships between objective childbirth and breastfeeding events, subjective childbirth and breastfeeding experiences, and emotional availability in the mother–infant relationship. Further, it aimed to test two psychological variables, psychological flexibility and self-compassion, as predictors of emotional availability. A convenience sample of 396 mothers of infants (<2 years) from Australia and New Zealand completed an online cross-sectional survey. Objective breastfeeding events (difficulties), negative subjective birth/breastfeeding experiences, poorer psychological flexibility, and lower self-compassion correlated with poorer emotional availability. After controlling for objective birth and breastfeeding variables using multiple linear regressions, better subjective breastfeeding experiences, psychological flexibility, and self-compassion predicted the mutual attunement aspect of emotional availability, whereas better subjective birth experiences and psychological flexibility predicted the affect quality aspect of emotional availability. Mothers’ subjective experiences of birth and breastfeeding are important in understanding the early mother–infant relationship. Psychological flexibility and self-compassion are important predictors of emotional availability and may be useful targets for psychological intervention aimed at optimising early mother–infant relationships.

横断面研究中的出生、母乳喂养、心理灵活性和自我同情作为母婴情感可用性的预测指标

本研究旨在检验客观分娩和母乳喂养事件、主观分娩和母乳喂养经历以及母婴关系中的情绪可用性之间的关系。此外，它旨在测试两个心理变量，心理灵活性和自我同情，作为情绪可用性的预测指标。来自澳大利亚和新西兰的 396 名婴儿（<2 岁）母亲的便利样本完成了一项在线横断面调查。客观母乳喂养事件（困难）、消极的主观分娩/母乳喂养经历、较差的心理灵活性和较低的自我同情心与较差的情绪可用性相关。在使用多元线性回归控制客观出生和母乳喂养变量后，更好的主观母乳喂养体验，心理灵活性和自我同情预测了情绪可用性的相互协调方面，而更好的主观出生经历和心理灵活性预测了情绪可用性的情感质量方面。母亲对分娩和母乳喂养的主观体验对于理解早期母婴关系很重要。心理灵活性和自我同情是情绪可用性的重要预测因素，可能是旨在优化早期母婴关系的心理干预的有用目标。母亲对分娩和母乳喂养的主观体验对于理解早期母婴关系很重要。心理灵活性和自我同情是情绪可用性的重要预测因素，可能是旨在优化早期母婴关系的心理干预的有用目标。母亲对分娩和母乳喂养的主观体验对于理解早期母婴关系很重要。心理灵活性和自我同情是情绪可用性的重要预测因素，可能是旨在优化早期母婴关系的心理干预的有用目标。
