An examination of emotion regulation as a mechanism underlying eating disorder pathology in lesbian, gay, and bisexual individuals

LGBTQ+ outpatients present to eating disorder treatment earlier and with more severe depressive symptoms than cisgender heterosexual peers

Community evidence indicates high eating disorder (ED) and comorbid symptom severity among LGBTQ+ compared to cisgender heterosexual (CH) individuals. Little is known about such disparities in ED treatment samples, especially in outpatient treatment. We aimed to descriptively characterize and investigate baseline group differences in symptom severity between LGBTQ+ and CH ED outpatients at treatment intake. Data from 60 (22.3%) LGBTQ+ and 209 (77.7%) CH ED outpatients were used to examine: (1) demographic and diagnostic differences; (2) differences in ED, depressive, and emotion dysregulation symptoms. Objectives were tested using Fisher-Freeman-Halton exact and independent samples t-tests, and analyses of covariance adjusted for age and diagnosis, respectively. Most LGBTQ+ outpatients were bisexual (55.2%), and 6.5% identified as transgender and non-binary. LGBTQ+ outpatients presented to treatment at younger ages (Mean Difference [MD] = -3.39, p = .016) and reported more severe depressive symptoms (MD = 5.73, p = .004) than CH patients, but endorsed similar ED symptom and emotion dysregulation severity. Groups did not differ in other demographic or diagnostic characteristics. LGBTQ+ individuals may develop more severe depression and similarly severe EDs at earlier ages but seek outpatient care sooner than CH peers. Managing depressive symptoms may be particularly important for LGBTQ+ ED patients.

Emotion regulation and OCD among sexual minority people: Identifying treatment targets

Sexual minority individuals experience higher rates of psychopathology, such that sexual minority people are nine times more likely to receive a diagnosis or treatment for obsessive-compulsive disorder (OCD) compared to heterosexual people. Poor emotion regulation capacity is a risk factor for OCD, but little is known about sexual orientation differences in dimensions of emotion regulation and how dimensions of emotion regulation relate to OCD severity among sexual minority people. The aims of the current study include 1) comparing sexual minority to heterosexual people on OCD severity and emotion regulation capacity upon admission to treatment for OCD, and 2) examining emotion regulation in relation to OCD severity among sexual minority people. Participants (N = 470) were adults in partial hospital/residential treatment with an average stay of 59.7 days (SD = 25.3), including 22 % sexual minority people. Sexual minority people reported a lower emotion regulation capacity. Among the largest three subgroups (heterosexual, bi+, and gay/lesbian), bi+ individuals reported a lower emotion regulation capacity compared to heterosexual but not gay/lesbian people. Results suggest there are sexual orientation differences in emotion regulation capacity, and that bi+ people have the most difficulty with ER. There is a need for OCD treatment to directly target emotion regulation strategies and be affirming of sexual minority identities.

Associations between body image patterns and body image-related pathology in sexual minority individuals: A mixture-modeling approach

Body image concerns are associated with disordered eating, body dysmorphic disorder (BDD), and illicit appearance and performance enhancing drug (APED) misuse. Sexual minority individuals are a vulnerable population for body image concerns. Latent profile analyses were used to identify body image patterns in sexual minority men (n = 479) and women (n = 483) and to investigate associations between latent profiles and body image-related pathology. A 5-profile solution demonstrated best fit for men and a 4-profile solution for women. Among women, co-occurring high thinness/muscularity concerns had higher probability of vomiting and dietary restriction than the high thinness/low muscularity concerns profile. The probability of driven exercise did not differ across latent profiles for men and only differed between low thinness/low muscularity and high thinness/high muscularity concerns profiles in women. Men with low thinness/high muscularity concerns had significantly lower probability of vomiting and laxative misuse than all other profiles but did not significantly differ from co-occurring high or moderate thinness/muscularity concerns profiles in binge eating and illicit APED misuse. This study may have implications for future research, treatment, and prevention of body image-related pathology in sexual minority individuals.

Toward inclusivity: A systematic review of the conceptualization of sexual minority status and associated eating disorder outcomes across two decades

OBJECTIVE

Sexual minority (SM) groups (e.g., those who identify as lesbian, gay, bisexual, questioning, queer, asexual, or those who feel their sexual orientation identity cannot be captured with existing terminology [LGBQA+] and those who report same-sex or same-gender attraction and/or behavior) are at elevated risk for eating disorder (ED) symptoms and behaviors. However, the ways in which this risk varies across SM is less clear, and findings are not fully convergent. Evolution in the definition and assessment of SM status may contribute to this divergence. The aim of this study was to systematically review how sexual orientation and SM status have been assessed in the ED literature and how this may relate to patterns of associations between SM status and ED symptoms.

METHODS

A systematic review of the literature focused on ED symptoms and behaviors and SM groups was conducted, yielding 182 studies.

RESULTS

Five categories were created reflecting SM status assessment: identity only (n = 105), attraction only (n = 8), behavior only (n = 4), combinations of identity, behavior, or attraction (n = 58), and articles with unclear or insufficient information about SM status assessment (n = 7). SM status operationalizations varied across studies, with more inclusive assessments in more recent work. Findings revealed persistent conflicting patterns of disordered eating symptomatology for some SM groups. In addition, decisions to selectively combine SM participants in some studies, most often to increase power, decreased the specificity of their results in relation to differential risk and protective factors within specific LGBQA+ groups.

DISCUSSION

Findings highlight the importance of inclusive assessments of sexual orientation in the ED literature and research focused on underrepresented groups with intersecting identities. Identifying modifiable targets for intervention is a critical next step.

PUBLIC SIGNIFICANCE

Sexual minority (SM) groups have been identified as presenting elevated risk for eating disorder symptoms and behaviors. Our findings suggest that the level of risk is variable across SM groups and points to the need for multi-dimensional assessments of SM status, and increased focus on the function of disordered eating behaviors and different profiles that might emerge related to efforts to modify physical appearance or to regulate emotion.

The Role of Emotion Regulation in Eating Disorders: A Network Meta-Analysis Approach

Background

Previous theoretical models and reviews have documented a strong connection between emotion dysregulation eating disorder (ED) psychopathology among the general and clinical populations. The aim of this review was to build on this previous work by conducting a network meta-analysis to explore associations between adaptive and maladaptive emotion regulation strategies and ED psychopathology trans-diagnostically across the ED spectrum to identify areas of emotion dysregulation that have the strongest association with symptomatology.

Methodology

A total of 104 studies were included in the meta-analysis and correlation coefficient representing the associations between specific emotion regulation strategies and ED symptomatology were extracted. We ran a Bayesian random effects network meta-analysis and the initial network was well-connected with each emotion regulation strategy being linked to at least one other strategy. We also conducted a network meta-regression to explore whether between-study differences in body mass index (BMI), age, and whether the sample consisted of solely female participants explained any possible network inconsistency.

Results

The network meta-analysis revealed that ruminations and non-acceptance of emotions were most closely associated with ED psychopathology. There was no significant network inconsistency but two comparisons approached significance and thus meta-regressions were conducted. The meta-regressions revealed a significant effect of BMI such that the associations between different emotion regulation strategies and ED symptomatology were weaker among those with low BMI.

Discussion

The present findings build on previous work and highlight the role of rumination and difficulties with accepting emotions as key emotion regulation difficulties in EDs. Additionally, the finding that the associations were weaker among ED patients with low BMI may point toward a complex relationship between ED behaviors and emotion regulation. Taken together, our findings call for interventions that target emotion regulation, specifically rumination and difficulties accepting emotions, in the treatment of EDs.
