To evaluate the acceptability and potential utility of a small package of online resources designed to improve self-compassion for mothers of infants. A within-groups repeated-measures study design was used. A community sample of 262 mothers who were ≤ 24 months post-partum were given access to a set of online resources (two videos plus a tip sheet) that outlined simple techniques for increasing self-compassion drawn from compassion-focused therapy (CFT). Participants completed pre-intervention assessment, followed by post-intervention assessment 1 month later. Assessment included self-report measures of self-compassion, psychological flexibility and shame in the mothering role; symptoms of post-traumatic stress (PTS) following childbirth; subjective breastfeeding experience; and satisfaction with infant feeding. Overall, 49.8% of participants accessed some or all of the resources, with lack of time the most common barrier to use. The vast majority (96%) agreed that self-compassion is helpful for women experiencing birth or breastfeeding difficulties. t tests examined change in scores from pre- to post-intervention, indicating increases in self-compassion, decreases in PTS symptoms (intrusion, hyperarousal and total PTS score) and improved subjective breastfeeding experience as well as overall satisfaction with breastfeeding. There were no changes in scores for psychological flexibility, shame, or satisfaction with general infant feeding. This pilot study supports the acceptability and potential utility of self-compassion resources, drawn from CFT, to support mothers’ well-being in the first years of their baby’s life. This novel approach to maternal health intervention warrants further exploration, development and testing in future research.
