Sexual Orientation-Based Differential Item Functioning in Measures of Body Image Concerns and Ideals among Men

A guide to exploratory structural equation modeling (ESEM) and bifactor-ESEM in body image research

Traditionally, assessments of factor validity of body image instruments have relied on exploratory or confirmatory factor analysis. However, the emergence of exploratory structural equation modeling (ESEM), a resurgence of interest in bifactor models, and the ability to combine both models (bifactor-ESEM) is beginning to shape the future of body image research. For these analytic approaches to truly advance body image research, scholars will need to have a deep understanding of their use and application. To facilitate such understanding, we describe ESEM and bifactor-ESEM models for body image researchers and provide them with the tools they need to apply these methods in their own work. Specifically, we provide an overview of ESEM and bifactor-ESEM models, and describe their broad applicability to body image research. Next, we describe how ESEM and bifactor models can be used and, using an existing dataset of responses to the Acceptance of Cosmetic Surgery Scale, demonstrate how ESEM and bifactor-ESEM models can be deployed. To facilitate wider application of these ideas, we provide our Mplus syntax (inputs) in Supplementary Materials. Through this manuscript, we hope to assist researchers to better understand the strengths ESEM and bifactor models, and to use these approaches in their own work.

Body image and associated factors among sexual minority men: A systematic review

Research suggests that the risk of body image concerns among sexual minority men is high. Recent work has increasingly examined body image in relation to psychological, interpersonal, and behavioral constructs, but these findings have yet to be consolidated and critically examined to identify potential risk and protective factors. The present study sought to systematically review and synthesize published findings on body image among sexual minority men. A total of 136 articles published between January 2011 and March 2022 were included. Sexual minority men were generally reported to have more negative body image compared to heterosexual men, yet findings varied across body image constructs. In correlational work, body image was often examined in relation to disordered eating, mental health, internalization of appearance ideals, objectification, sexual behavior and relationships, gay community identification and discrimination, and health concerns (e.g., HIV, AIDS). Robust relationships emerged among body image and stigma variables, including internalized homophobia and harassment related to LGBTQ+ presentation and intersecting minority identities. Sociocultural, objectification, and minority stress theories were employed to interpret findings and to delineate future directions grounded in intersectional approaches. Additional work focused on the role of stigma and discrimination in the development of these concerns across the lifespan is needed.
