Associations between body dissatisfaction and relationship functioning among same-sex female couples: An actor-partner interdependence model.

Nearly all past research about body dissatisfaction and romantic relationship factors is among heterosexual couples; little is known about these associations in sexual minority couples. The present study aimed to fill gaps in the current literature by using actor-partner interdependence models (APIMs) to examine dyadic patterns of association between body dissatisfaction and different aspects of relationship functioning among same-sex female couples. Participants were 163 same-sex female romantic dyads (326 women) between the ages of 18-35 years who completed measures of body dissatisfaction and relationship factors. Results from significance testing of actor and partner effects indicated higher levels of women's own body dissatisfaction were associated with lower levels of their own, but not their partner's, relationship satisfaction, closeness, sexual satisfaction, and intimacy/connectedness. Significance testing alone indicated that the association between one's own body dissatisfaction and their partner's relationship satisfaction was not significant. However, dyadic pattern testing identified a partner pattern for this effect, which suggests that the association between one's own body dissatisfaction and one's own relationship satisfaction is similar in magnitude and direction as that between an individuals' own body dissatisfaction and their partner's relationship satisfaction. In this study, women's own body dissatisfaction was found to be negatively associated with their own relationship functioning, which is consistent with findings of women in male-female couples. Thus, these findings highlight the important role that body dissatisfaction plays in women's relationship experiences. More research is needed to better understand potential cross-partner effects of body dissatisfaction and relationship factors in same-sex female couples.

Evaluating the real-world predictive validity of the Body Image Quality of Life Inventory using Ecological Momentary Assessment.

Perceptions of physical appearance, or body image, can affect psychosocial functioning and quality of life (QOL). The present study evaluated the real-world predictive validity of the Body Image Quality of Life Inventory (BIQLI) using Ecological Momentary Assessment (EMA). College women reporting subclinical disordered eating/body dissatisfaction (N=131) completed the BIQLI and related measures. For one week they then completed five daily EMA surveys of mood, social interactions, stress, and eating behaviors on palmtop computers. Results showed better body image QOL was associated with less negative affect, less overwhelming emotions, more positive affect, more pleasant social interactions, and higher self-efficacy for handling stress. Lower body image QOL was marginally related to less overeating and lower loss of control over eating in daily life. To our knowledge, this is the first study to support the real-world predictive validity of the BIQLI by identifying social, affective, and behavioral correlates in everyday life using EMA.
