Abstract
Extensive cross-sectional research reports that body fat and muscularity dissatisfaction contribute to negative psychological outcomes among sexual minority men; however, longitudinal models are necessary for accurately quantifying the strength and direction of these relationships. We investigated the bidirectional longitudinal relationships of body fat and muscularity dissatisfaction with psychological quality of life among 2953 sexual minority men using random intercept cross-lagged panel models. Consistent with existing literature, we found that higher average muscularity and body fat dissatisfaction were associated with higher average psychological quality of life impairment between-persons. Unexpectedly, these constructs were not significantly associated within-persons/longitudinally. These findings conflict existing literature’s conclusions that muscularity and body fat dissatisfaction consistently contribute to poorer psychological wellbeing in this population. A significant between-person relationship in the absence of within-person relationships suggests that intermediary constructs (e.g., body ideal internalization) may account for the between-person effects of muscularity and body fat dissatisfaction on psychological wellbeing. Future research can accurately estimate these effects and identify reliable intervention targets by ensuring that within- and between-person relationships are examined separately, rather than being conflated.
期刊介绍:
Body Image is an international, peer-reviewed journal that publishes high-quality, scientific articles on body image and human physical appearance. Body Image is a multi-faceted concept that refers to persons perceptions and attitudes about their own body, particularly but not exclusively its appearance. The journal invites contributions from a broad range of disciplines-psychological science, other social and behavioral sciences, and medical and health sciences. The journal publishes original research articles, brief research reports, theoretical and review papers, and science-based practitioner reports of interest. Dissertation abstracts are also published online, and the journal gives an annual award for the best doctoral dissertation in this field.
