Functions of disordered eating behaviors: a qualitative analysis of the lived experience and clinician perspectives.

BACKGROUND: One method to improve treatment outcomes for individuals with eating disorders (EDs) may be understanding and targeting individuals' motives for engaging in DE behaviors-or the functions of DE behaviors. The goal of this study was to investigate and categorize the various functions of DE behaviors from the perspectives of adults who engage in DE behaviors and clinicians who treat EDs. METHODS: Individuals who engage in DE behaviors (n = 16) and clinicians who treat EDs (n = 14) were interviewed, and a thematic analysis was conducted to determine key functions of DE behaviors. RESULTS: Four main functions of DE behaviors were identified by the authors: (1) alleviating shape, weight, and eating concerns; (2) regulating emotions; (3) regulating one's self-concept; and (4) regulating interpersonal relationships/communicating with others. CONCLUSIONS: Differences in participant responses, particularly regarding the relevance of alleviating shape and weight concerns as an DE behavior function, highlight the importance of individualized conceptualizations of DE behavior functions for any given client.

There are many reasons why individuals engage in disordered eating (DE) behaviors, and gathering information on these functions of one's DE behaviors might help clinicians decide which treatments to administer to individual clients. This study identified and organized numerous functions of DE behaviors based on perspectives of both adults who engage in DE behaviors and clinicians who treat EDs. These functions can be largely grouped into four categories: (1) reducing concerns about one's shape, weight, and/or eating habits; (2) managing one's emotions; (3) managing one's beliefs about themselves as a person; and (4) managing relationships with others or communicating with others. Using treatments that address these reasons for one's DE behaviors may be beneficial for clients.

#BoPo: Does viewing body positive TikTok content improve body satisfaction and mood?

Body positivity - often referenced on social media as "#BoPo" - encourages acceptance towards all body types, including one's own body, and challenges the societal ideal of the very thin body. The current study examined whether viewing body-positive TikTok content improves state mood and body satisfaction. Participants were female undergraduate students (N = 156) who completed an online study where they were randomly assigned to view either body-positive, body-focused, or control TikTok videos for five minutes. Before and after viewing the TikTok content, participants completed questionnaire items to assess state affect and body satisfaction alongside other variables. Mixed between-within subject ANOVAs demonstrated that participants in the body-positive condition experienced an increase in body satisfaction and a decrease in negative affect after viewing the body-positive TikTok videos. In contrast, those in the body-focused condition experienced a decline in body satisfaction and positive affect and an increase in negative affect. This study provides preliminary evidence that TikTok content may be used as a positive outlet for body image, depending on the type of content being viewed.

How Different Are Threshold and Other Specified Feeding and Eating Disorders? Comparing Severity and Treatment Outcome.

Background: Other Specified Feeding and Eating Disorders (OSFED) are characterized by less frequent symptoms or symptoms that do not meet full criteria for another eating disorder. Despite its high prevalence, limited research has examined differences in severity and treatment outcome among patients with OSFED compared to threshold EDs [Anorexia Nervosa (AN), Bulimia Nervosa (BN), and Binge Eating Disorder (BED)]. The purpose of the current study was to examine differences in clinical presentation and treatment outcome between a heterogenous group of patients with OSFED or threshold EDs. Method: Patients with threshold EDs (AN = 42, BN = 50, BED = 14) or OSFED (n = 66) presenting for eating disorder treatment completed self-report questionnaires at intake and discharge to assess eating disorder symptoms, depression symptoms, impairment, and self-esteem. Results: At intake, OSFED patients showed lower eating concerns compared to patients with BN, but similar levels compared to AN and BED. The OSFED group showed higher restraint symptoms compared to BED, and similar restraint to AN and BN. Global symptoms as well as shape and weight concerns were similar between OSFED and threshold ED groups. There were no differences between diagnostic groups in self-esteem, depression scores, or symptom change from intake to discharge. Discussion: Our findings suggest that individuals with OSFED showed largely similar ED psychopathology and similar decreases in symptoms across treatment as individuals diagnosed with threshold EDs. Taken together, findings challenge the idea that OSFED is less severe and more resistant to treatment than threshold EDs.

Weight misperception and its associations with eating disorder symptoms over the course of residential eating disorder treatment.

OBJECTIVE: Although individuals with eating disorders (EDs) often experience significant body dissatisfaction and perceptual body image distortions, the presence and impact of weight misperception in clinical samples have been minimally examined. The aims of this study were to quantify weight misperception in individuals with EDs, examine whether weight misperception predicts ED severity at treatment discharge, and explore changes in weight misperception across treatment. METHOD: Participants were 98 women seeking residential treatment for their ED who reported weekly on their perceived weight. Objectively measured weight was subtracted from perceived weight to determine weekly "weight misperception." Participants completed the Eating Disorder Examination Questionnaire (EDE-Q) at intake and discharge to assess ED severity. Weight misperception at intake and change in weight misperception over treatment were examined as predictors of ED pathology at discharge. RESULTS: Approximately 74.5% of the sample overestimated their weight, with an average weight misperception of 2.7 (SD = 5.6) pounds (1.2 kg; SD = 2.5). Weight misperception spanned from -6.2 to 43.6 pounds (-2.8 to 19.8 kg) and did not differ based on ED diagnosis. On average, weight misperception increased throughout treatment. Greater weight misperception at intake as well as greater increases in weight misperception over treatment significantly predicted EDE-Q scores at discharge. DISCUSSION: Findings highlight that weight misperception is not limited to underweight patients. Misperceiving one's weight may predict symptom severity across a range of EDs, and future research is needed to examine whether targeting weight misperception during residential treatment could improve treatment outcomes for individuals with EDs.
