An investigation of self-compassion and nonattachment to self in people with bipolar disorder

There have been longstanding theories and research evidence into the important role of the person's vulnerability at the level of self-concept in bipolar disorder (BD). The current study investigated two emerging self-related constructs, self-compassion and nonattachment to self in BD. Specifically, we examined the levels of the two constructs in people with BD compared with those from the general population, and the associations between the constructs and bipolar symptomologies within the BD group.

The BD group consisted of 302 individuals with a diagnosis of BD participating in an international randomised controlled trial. A general population sample (n = 372) was recruited from an Australian university as a comparison group. All participants completed measures of self-compassion and nonattachment to self. The BD group completed additional measures of depression and symptoms of hypo/mania.

Participants with BD showed significantly lower self-compassion and nonattachment to self than those from the comparison group after controlling for demographic variables (e.g., gender, age, education, occupation). In the BD group, lower self-compassion and nonattachment to self were associated with greater severity of depression on both self- and clinician-rated scales. Nonattachment to self but not self-compassion was negatively associated with hypo/mania symptomology.

The cross-sectional design cannot determine the direction of the relationships between study variables. Nonattachment to self is a novel psychological construct and further research is needed to replicate study findings.

The study findings suggest that self-compassion and nonattachment to self may be meaningful targets in psychological interventions for people with BD.
