A multi-modal assessment of fear conditioning in adolescent anorexia nervosa.

OBJECTIVE: Anorexia nervosa (AN) is a pernicious psychiatric disorder which is principally characterized by a fear of weight gain. Notwithstanding the centrality of fear in the psychopathology of AN, controlled assessments of negative valence systems are lacking. Herein we assess fear conditioning in adolescent females with AN. METHOD: Adolescent girls (Mage = 14.6 years, ±1.57) with DSM-5 diagnoses of AN (N = 25) and age-matched control girls (Mage = 14.8 years, ±1.46) with no DSM-5 diagnoses (N = 25) completed structured clinical interviews and participated in a classical three-phase Pavlovian fear conditioning paradigm. Participants with comorbid anxiety disorders were excluded. Skin conductance response (SCR) was measured, alongside self-reported fear, valence, and fear expectancy ratings. RESULTS: Both groups demonstrated significant differential acquisition across all four measures. Regarding group comparisons, no differences emerged for self-reported fear, valence, and fear expectancy ratings during acquisition, although for SCR, those with AN demonstrated reduced physiological arousal relative to controls. Both groups demonstrated significant differential extinction for unconditioned stimuli (US) expectancy, self-report fear, and self-report valence. No statistically significant group differences were evident during extinction to the conditioned stimuli (CS)+, on any outcome measure. However, controls reported more positive valence to the CS- than those with AN. CONCLUSIONS: Contrary to our hypotheses, our preliminary assessment did not find support for elevated fear responding among adolescent girls with AN with regards to fear acquisition or extinction. These data suggest that AN in adolescent girls may not be associated with a heightened propensity to acquire fear, but conversely, may suggest that exposure treatments for AN may be helpful, since extinction learning is intact in AN. PUBLIC SIGNIFICANCE: AN is characterized by fear-related symptoms, including food and weight-related fear, and behavioral avoidance, yet controlled studies assessing fear learning are limited. Our preliminary assessment of adolescent AN indicates no abnormalities in fear learning among adolescents with AN. These findings may inform existing mechanistic models of AN psychopathology, and the development of exposure-based treatments for AN.

Community norms for the eating disorder examination questionnaire (EDE-Q) among cisgender bisexual plus women and men.

PURPOSE: Cisgender bisexual plus (including bisexual, pansexual, and polysexual) women and men experience unique health concerns including eating disorders. The purpose of this study was to develop community norms for eating disorder attitudes and disordered eating behaviors in cisgender bisexual plus women and men using the Eating Disorders Examination Questionnaire (EDE-Q). METHODS: Participants were cisgender bisexual plus women (n = 462) and men (n = 93) participants in The PRIDE Study, an existing study of sexual and gender minority people. RESULTS: Mean and standard deviation of EDE-Q scores among cisgender bisexual plus women and men, respectively, were: Global (1.75 ± 1.26, 1.56 ± 1.18), Restraint (1.34 ± 1.44, 1.42 ± 1.53), Eating Concern (0.96 ± 1.13, 0.63 ± 0.96), Weight Concern 2.27 ± 1.55, 1.89 ± 1.46), and Shape Concern 42 ± 1.62, 2.30 ± 1.57). Among cisgender bisexual plus women and men, respectively, 27.5% and 22.6% scored in the clinically significant range on the Global score. Bisexual plus women and men reported any occurrence (≥ 1/28 days) of dietary restraint (19.3%, 23.7%), objective binge episodes (11.1%, 10.8%), excessive exercise (4.5%, 5.4%), self-induced vomiting (1.7%, 0.0%), and laxative misuse (0.4%, 1.1%), respectively. A lower percentage of age-matched cisgender bisexual plus women (18-25 years) reported any occurrence of objective binge episodes, self-induced vomiting, laxative misuse, and excessive exercise than previously published in young women. Age-matched cisgender bisexual plus men (18-26 years) reported higher weight concern subscale scores than previously published in young men. CONCLUSIONS: These norms should aid clinicians in applying and interpreting the EDE-Q scores of cisgender bisexual plus women and men. LEVEL OF EVIDENCE: Level V: cross-sectional descriptive study.

Eating disorder attitudes and disordered eating behaviors as measured by the Eating Disorder Examination Questionnaire (EDE-Q) among cisgender lesbian women.

The Eating Disorder Examination Questionnaire (EDE-Q) is a measure of eating disorder attitudes and disordered eating behaviors. Prior descriptive studies of the EDE-Q for women either did not assess or omitted reporting sexual orientation. This study's objective was to assess eating disorder attitudes and disordered eating behaviors as measured by the EDE-Q among cisgender lesbian women. We present mean scores and standard deviations for the EDE-Q among 563 self-identified cisgender lesbian women ages 18-77 who were recruited from The PRIDE Study in 2018. Among cisgender lesbian women, 3.4 % scored in the clinically significant range on the Restraint, 1.6 % on the Eating Concern, 9.1 % on the Weight Concern, 13.9 % on the Shape Concern, and 3.9 % on the Global Score scales of the EDE-Q. We found that 13.5 % of participants reported any occurrence (≥1/28 days) of dietary restriction, 8.7 % for objective binge episodes, 5.3 % for excessive exercise, .4% for self-induced vomiting, and .4% for laxative misuse. Participants reported a current (1.8 %) or lifetime (7.1 %) diagnosis of an eating disorder by a clinician. These EDE-Q descriptive data capture eating disorder attitudes and disordered eating behaviors among cisgender lesbian women and may aid clinicians and researchers in interpreting the EDE-Q in this specific population.

Community norms for the Eating Disorder Examination Questionnaire (EDE-Q) among transgender men and women.

Transgender men and women may be at risk for eating disorders, but prior community norms of the Eating Disorders Examination Questionnaire (EDE-Q) are based on presumed cisgender men and woman and have not intentionally included transgender people. The objective of this study was to develop community norms for eating disorder attitudes and disordered eating behaviors in transgender men and women using the EDE-Q. Participants were 312 transgender men and 172 transgender women participants in The PRIDE Study, an existing cohort study of sexual and gender minority people. We present mean scores, standard deviations, and percentile ranks for the Global score and four subscale scores of the EDE-Q in transgender men and women. Transgender men and women reported any occurrence (≥1/week) of dietary restraint (25.0% and 27.9%), objective binge episodes (11.2% and 12.8%), excessive exercise (8.0% and 8.1%), self-induced vomiting (1.6% and 1.7%), and laxative misuse (.3% and .6%), respectively. Compared to a prior study of presumed cisgender men 18-26 years (Lavender, De Young, & Anderson, 2010), our age-matched subsample of transgender men reported lower rates of objective binge episodes and excessive exercise. Compared to a prior study of presumed cisgender women 18-42 years (Mond, Hay, Rodgers, & Owen, 2006), we found that an age-matched sample of transgender women reported higher rates of dietary restraint but lower rates of excessive exercise. These norms should aid clinicians in applying and researchers in investigating and interpreting the EDE-Q scores of transgender men and women.
