A dyadic analysis of relationship satisfaction and depressive symptoms among same-sex couples

Sexual minority individuals experience depression at a disproportionately higher rate than their heterosexual peers. One predictor of depression is low romantic relationship satisfaction, and research on different-sex couples demonstrates that one's own and one's partner's levels of relationship satisfaction are negatively associated with one's own level of depressive symptoms (i.e., actor and partner effects, respectively). However, little research has explored partner effects of relationship satisfaction on depression in same-sex couples. Furthermore, little is known regarding the degree to which relationship satisfaction is associated with depression in same-sex couples, over and above their shared association with demographic characteristics and internalized heterosexism, a known correlate of both relationship satisfaction and depression. This study examined cross-sectional actor and partner effects of relationship satisfaction on depressive symptoms in a sample of 102 same-sex couples (68 female), and evaluated whether these effects were significant when adjusting for sex, relationship length, and internalized heterosexism. Multilevel analyses were conducted to estimate actor-partner interdependence model (APIM) effects for indistinguishable dyads. Results indicated that (a) there were statistically significant actor and partner effects for relationship satisfaction on depressive symptoms, such that higher levels of relationship satisfaction were associated with lower levels of depressive symptoms and (b) actor and partner effects for relationship satisfaction remained statistically significant when adjusting for sex, relationship length, and actor and partner effects for internalized heterosexism. Furthermore, there were statistically significant actor (but not partner) effects for internalized heterosexism on depressive symptoms, such that higher levels of internalized heterosexism were associated with higher levels of depressive symptoms.
