The Roles of Social Comparison Orientation and Regulatory Focus in College Students' Responses to Fitspiration Posts on Social Media: Cross-sectional Study

Negative Affect as a Mediator Between Exposure to Fitspiration and Thinspiration and Disordered Eating Behaviors: An Ecological Momentary Assessment Study

OBJECTIVE

Although social media use, such as Instagram, has been associated with ED pathology, mechanisms connecting social media use to disordered eating behaviors (DEBs) remain largely unevaluated. Based on Dual Process, Tripartite, and Affect Regulation models of ED pathology, we proposed a moderated mediation model evaluating impacts of exposure to fitspiration/thinspiration on Instagram.

METHOD

We evaluated a hypothesized pathway from exposure to fitspiration/thinspiration (i.e., ED-salient content) on Instagram to disordered eating mediated by negative affect and tested individual differences in weight bias internalization, trait self-esteem, and trait self-comparison as moderators. We recruited 173 undergraduate women who reported engaging in DEBs on average at least once per week over the past 3 months. Participants completed a seven-day ecological momentary assessment protocol, during which they reported their ED-salient content exposure on Instagram, affect, and engagement in DEBs.

RESULTS

Multilevel modeling was used to assess moderated mediation. Negative affect partially mediated associations between viewing ED-salient content and subsequent engagement in objective binge eating and restricting but did not mediate the pathway to purging or excessive exercise. Higher weight bias internalization intensified the association between viewing ED-salient content and negative affect.

DISCUSSION

The association between viewing ED-salient content and engaging in objective binge eating and restricting may be a partial consequence of elevated negative affect; however, effects were small. Individuals with higher weight bias internalization may be more vulnerable to negative consequences from viewing ED-salient content. Findings suggested that reducing negative affect responses (e.g., via emotion regulation) could reduce negative consequences of viewing ED-salient content.

Social Media and Self-Concept Among Postsecondary Students: A Scoping Review

The vast majority of college-aged students use social networking sites (SNS) to foster connectedness and enable networking. In addition, SNS allow individuals to control their online self-presentation. This may lead to incongruence between students' actual selves and their curated online selves, thereby damaging one's self-perception by increasing social comparison orientation. The goal of this article was to investigate the relationship between SNS use and self-concept that has not yet been explored in depth among the postsecondary population. Utilizing Arksey and O'Malley's methodological framework, a scoping review of the published literature was conducted. A total of 41 articles were included in the review. Three overarching themes were extracted from the findings. The first theme found that consistent exposure to the thin ideal and fitspiration posts across various SNS were linked to increased body dissatisfaction. The second theme found that engaging in online academic or ability-based comparisons resulted in a worsened mental state among postsecondary students. The third theme found that one's SNS followers or the number of "likes" received have mixed effects on student self-concept. Through gaining an improved understanding of the SNS stressors that contribute to students' mental health from this review, postsecondary institutions can implement more targeted interventions to bolster student wellbeing.

Tendencies for Comparing Up and Down: An Examination of the Directional Subscales of the Iowa-Netherlands Comparison Orientation Measure

People vary in their individual tendencies to compare to others-referred to as social comparison orientation (SCO). Researchers have heretofore developed and validated a scale to assess SCO-the Iowa-Netherlands Comparison Orientation Measure (INCOM). The standard INCOM assesses non-directional comparisons, but not directional comparisons to better- and worse-off others. The goal of the present research was to examine the factor structure and validity of directional (and non-directional) comparison tendencies using the expanded INCOM. Across four archival studies and one pre-registered study using student and non-student samples, we provide evidence for 1) a 3-factor structure for the INCOM with non-directional, directional-upward, and directional-downward SCO dimensions, 2) inter-correlations among the SCO dimensions suggesting convergent validity of the directional scales, 3) greater endorsement of non-directional, then directional-upward, and directional-downward SCO, 4) lower SCO among older individuals and members of racial/ethnic minority groups, and 5) strong and consistent associations of directional-upward SCO with well-being and affect, appearance beliefs (e.g., body satisfaction), social emotions (e.g., envy), and agency-related motivations and consequences in interpersonal contexts, but smaller and less consistent associations of non-directional and directional-downward SCO with outcomes (with notable exceptions). Taken together, this research indicates that SCO is a multi-faceted individual difference variable.

Prospectively predicting naturalistic exposure to fitspiration and thinspiration in young women with disordered eating by leveraging an ecological momentary assessment design

OBJECTIVE

Although a growing body of research has examined the impacts of ED-salient content, such as fitspiration and thinspiration, on eating disorder (ED) symptoms, there is less known about the characteristics of who may be at risk for accessing this content on Instagram. Current research is limited by cross-sectional and retrospective designs. This prospective study used ecological momentary assessment (EMA) to predict naturalistic exposure to ED-salient content on Instagram.

METHODS

Female university students with disordered eating (N = 171, Mage = 20.23, SD = 1.71, range = 18-25) completed a baseline session, followed by a seven-day EMA protocol, in which they reported on Instagram use and exposure to fitspiration and thinspiration. Mixed-effects logistical regressions were used to predict exposure to ED-salient content on Instagram from four principal components (e.g., behavioral ED symptoms and trait social comparison) controlling for duration of Instagram use (i.e., dose) and day of study.

RESULTS

Duration of use was positively associated with all types of exposure. Purging/cognitive restraint and excessive exercise/muscle building prospectively predicted access to any ED-salient content and fitspiration only. Restricting positively predicted thinspiration only access. Purging/cognitive restraint positively predicted accessing fitspiration and thinspiration (dual exposure). Day of study was negatively associated with any exposure, fitspiration only, and dual exposure.

CONCLUSIONS

Baseline ED behaviors were differentially associated with exposure to ED-salient Instagram content; however, duration of use was also a significant predictor. Limiting use of Instagram may be important for young women with disordered eating to reduce probability of encountering ED-salient content.

TikTok on the clock but the #fitspo don't stop: The impact of TikTok fitspiration videos on women's body image concerns

Fitspiration is a popular social media trend that aims to inspire individuals to improve their health and fitness through diet and exercise. However, viewing fitspiration content on Instagram has been identified as a contributor to negative body image, especially for young women. With the growing popularity of the video sharing platform TikTok and concerns over its content, the present study aimed to experimentally examine the effect of exposure to fitspiration TikTok videos on young women's body dissatisfaction, appearance comparison and mood. The roles of state appearance comparison as a mediator and trait fit ideal internalisation as a moderator were also considered. Young women (18-25, N = 120) from Australia were randomly allocated to view a set of fitspiration videos or a set of art control videos from TikTok. Results indicated that exposure to fitspiration TikTok videos increased state appearance comparison and state negative mood relative to art TikTok videos but did not directly increase state body dissatisfaction. State appearance comparison significantly mediated the effect of TikTok videos on body dissatisfaction and mood, however, there was no moderating effect of trait fit ideal internalisation. These findings highlight the importance of state appearance comparison in relation to viewing fitspiration content on TikTok.
