Enhancing body image in motherhood: A randomised controlled trial of Expand Your Horizon among mothers of young children

Motherhood can increase vulnerability to body dissatisfaction, but positive body image interventions may mitigate this. Expand Your Horizon (Alleva et al., 2015), an online writing intervention, enhances functionality appreciation, an aspect of positive body image. The intervention's demonstrated efficacy and focus on body functionality indicate its potential use among mothers. However, its original 3-session format may be unfeasible for mothers alongside other commitments. Thus, we tested the impact of a single 15-minute Expand Your Horizon session on state body appreciation and functionality appreciation. Mothers (N = 143) of 0-10-year-olds were randomly allocated to either the intervention group, or an active control group. State body appreciation and functionality appreciation were assessed pre- and post-intervention. Trait self-compassion was tested as a potential moderator. Participants who completed Expand Your Horizon reported greater state body appreciation and functionality appreciation post-intervention than those in the control group. Self-compassion moderated the intervention's effect on state functionality appreciation, with effects strongest for those with lower levels of self-compassion. Overall, findings support the intervention's suitability for mothers, particularly those with low self-compassion. Practical implications include possibly tailoring Expand Your Horizon and similar interventions to benefit all mothers. Future research directions include longitudinal and qualitative designs, and extension to other specific populations.
