A two-week daily diary study examining the association between daily self-compassion and symptoms of bulimia nervosa

Individuals with symptoms of bulimia nervosa (BN) are more likely to binge and purge on days of greater negative affect. Given that self-compassion helps individuals cope more adaptively with distress, the present study examined the contribution of daily fluctuations in self-compassion to eating disorder symptoms in women who endorse symptoms of BN. The directionality of these associations was also examined.

For 2 weeks, 124 women who met the DSM-5 criteria for BN completed nightly measures of their daily eating pathology and self-compassion.

Self-compassion levels varied almost as much within a person from day-to-day as between-persons (i.e., from one person to the next). Multilevel modeling revealed that within persons, higher daily levels of self-compassion were associated with a reduced probability of both binge eating and inappropriate compensation, and lower levels of dietary restraint and clinical impairment. Secondary analyses revealed that these variables mutually influenced one another within but not across days. Between persons, higher mean levels of self-compassion over the 2 weeks were associated with less dietary restraint and clinical impairment but were unrelated to binge eating and compensatory behaviors.

For women who report symptoms consistent with BN, responding to daily distress with greater self-compassion than usual may attenuate the psychosocial and behavioral symptoms of their eating disorder. Similarly, days of reduced eating pathology may facilitate self-compassion. Future research using experimental paradigms and ecological momentary assessments may shed further light on the ways in which self-compassion and eating pathology relate to one another in this population.
