The impact of social media use on body image and disordered eating behaviors: Content matters more than duration of exposure.

Social media use is rapidly expanding in terms of frequency, duration, and the diversity of platforms available. Given evidence for associations between social media use, body image disturbances, and disordered eating it is important to identify potentially harmful aspects of social media use that could serve as intervention targets. This study surveyed two demographically diverse undergraduate student cohorts in 2015 and 2022 to compare patterns in social media use, body image, and disordered eating behaviors between samples, including as a function of the COVID-19 pandemic, and to test the hypothesized moderating role of specific content consumed in the association between social media use and maladaptive outcomes. Participants in 2022 reported greater body image disturbances, more frequent vomiting and laxative use, and more time spent on a greater number of social media accounts, with significantly greater use of image-based platforms such as Snapchat, TikTok, and YouTube. Moderated regression analyses suggest that type of content consumed, but not the amount of time spent on social media or diversity of platforms utilized, is associated with body image disturbances and disordered eating behaviors after controlling for gender and body mass index. Specifically, exposure to weight loss content was associated with lower body appreciation, greater fears of negative appearance evaluation, and more frequent binge eating. Contrary to initial hypotheses, exposure to body positivity/neutrality content did not have protective effects. Findings suggest that interventions targeting negative consequences of social media use should focus on addressing content consumed, rather than time spent on social media platforms.

Does culture create craving? Evidence from the case of menstrual chocolate craving.

Craving is considered a key characteristic of diverse pathologies, but evidence suggests it may be a culture-bound construct. Almost 50% of American women crave chocolate specifically around the onset of menstruation. Research does not support popular accounts implicating physiological factors in menstrual chocolate craving etiology. We tested the novel hypothesis that greater menstrual craving prevalence in the U.S. is the product of internalized cultural norms. Women of diverse backgrounds (n = 275) reported on craving frequency and triggers and completed validated measures of acculturation. Foreign-born women were significantly less likely to endorse menstrual chocolate craving (17.3%), compared to women born to U.S.-born parents (32.7%, p = .03) and second generation immigrants (40.9%, p = .001). Second generation immigrant and foreign-born women endorsing menstrual chocolate craving reported significantly greater U.S. acculturation and lower identification with their native culture than non-menstrual cravers (all p < .001). Findings inform our understanding of food cravings, with important implications for the study of cravings in other domains.

Development and initial validation of the obsessive compulsive eating scale.

OBJECTIVE: Food cravings are common and have been implicated in eating-related pathology, including binge eating, bulimia nervosa, and unhealthy weight problems, but difficulties in defining and quantifying the phenomenon of craving are well documented. There has been an increase in focus on the study of cognitive mechanisms underlying craving, in particular the role of intrusive thoughts; however, existing craving measures fail to fully capture these aspects of the craving experience. The present study was designed to develop a psychometrically sound measure of the obsessive-compulsive aspects of food cravings. METHODS: The proposed 14-item Obsessive Compulsive Eating Scale (OCES) is based on the existing and well-validated Obsessive Compulsive Drinking Scale, a self-report measure of obsessive thoughts about drinking and compulsive behaviors directed towards alcohol consumption. The OCES was administered to 224 respondents (57.4%, n = 128 women). RESULTS: Results of confirmatory factor analyses suggested a two-factorial structure of the OCES, which mirrors that of the Obsessive Compulsive Drinking Scale, on which it is based. The OCES had excellent internal consistency (Cronbach's α = 0.91) and demonstrated good convergent and criterion validity. CONCLUSIONS: The proposed OCES is a psychometrically sound addition to the body of measurements used to assess food cravings and their role in disordered eating patterns.
