Exploring Relations Between Psychological Capital, Social Support and Self-Compassion Among Siblings of Individuals With Developmental Disabilities.

BACKGROUND

We examined correlations between psychological capital (PsyCap), social support and self-compassion among siblings of individuals with developmental disabilities versus siblings of individuals without developmental disabilities.

METHODS

We hypothesized that (1) there would be positive correlations between PsyCap, social support and self-compassion at the sample level and within each group; (2) siblings of individuals without developmental disabilities would exhibit lower levels of these variables than siblings of individuals with developmental disabilities; and (3) relations between social support and self-compassion would be mediated by PsyCap in both groups. We surveyed 154 adults aged 18-71 years, including 42 siblings of individuals with developmental disabilities (19-71 years) and 112 siblings of individuals without developmental disabilities (18-71 years).

RESULTS

Results indicated significant positive correlations between PsyCap, social support and self-compassion at the sample level and among siblings of individuals without developmental disabilities. As hypothesized, PsyCap mediated relations between social support and self-compassion. Contrary to expectations, no significant differences were found between the two groups in levels of PsyCap, social support or self-compassion.

CONCLUSION

These findings suggest that PsyCap constitutes a key internal psychological resource that supports self-compassion among siblings, including those of individuals with developmental disabilities, highlighting its potential value as a target for interventions promoting sibling well-being.
