Brief Self-Compassion Intervention for Women of Higher Weight and Internalized Weight Bias: A Randomized Pilot Study.

Abstract

Background: Internalized weight bias (IWB) negatively impacts mental and physical health, and disproportionately affects women of higher weight. Although self-compassion training may be advantageous for reducing IWB and associated sequalae, further examination of its clinical significance and cultural acceptability is warranted.

Method: A randomized pilot study was conducted to evaluate the feasibility, including cultural acceptability, and clinical significance of a 3-session self-compassion intervention (SCI) for women with IWB. Women with BMIs of > 25 and IWB (N = 34) were randomly assigned to the SCI or a waitlist control group. Participants completed pre, post, and 1-month follow-up surveys on IWB, self-compassion, body image, eating behaviors, physical activity, and affect. Analyses of covariance were employed and percentages of change were calculated to examine post-intervention between-group differences in outcomes. Cultural acceptability was evaluated through participants' ratings of the perceived inclusivity and relevancy of the SCI.

Results: There were 59% (n = 10) and 47% (n = 8) completion rates in the SCI and waitlist control groups, respectively. Compared to the waitlist control group, SCI participants reported greater pre-post improvements in self-compassion, IWB, body shame and surveillance, uncontrolled eating, and physical activity with medium to large effect sizes, and emotional eating with small effects. The SCI was perceived to be beneficial overall, and cultural acceptability ratings were mostly favorable despite individual differences.

Conclusion: This brief SCI may be beneficial for women impacted by weight stigma and IWB. Attention to increased diversity and cultural acceptability is warranted in future trials.
