The study population consisted of 146 girls and 163 boys with an average age of 16.0 years, recruited from two randomly selected high schools in Istanbul. The researchers calculated their minimum sample size using G*Power software, adopting a small-to-medium effect size consistent with Cohen’s criteria for the social and behavioral sciences, and determined that at least 285 students would be needed to detect significant relationships in correlation and regression analyses. Participants were physically and mentally healthy volunteers drawn from a total school population of 1,457 students. Height and body weight were measured directly, and body mass index-for-age percentiles were calculated according to standard pediatric classifications, with 78.3 percent of participants falling within the healthy weight range.

The methodological design relied on three validated psychometric instruments administered face-to-face. The social media use scale, developed by Deniz and Tutgun-Ünal, contains eight items divided into two subscales: continuity of social media use and social media use competence. The continuity subscale captures not merely the duration of daily use but the habitual, psychologically embedded nature of access, reflected in items such as checking accounts immediately before sleeping and right after waking. The social appearance anxiety scale, developed by Hart and colleagues and adapted into Turkish by Doğan, comprises 16 items assessing the anxiety and stress experienced when one’s physical appearance is evaluated by others. The Eating Disorder Examination Questionnaire-Short Form, or EDE-Q-13, evaluates eating behaviors over the preceding 28 days across five subdimensions: eating restraint, shape and weight over-evaluation, body dissatisfaction, binging, and purging. Internal consistency coefficients for the three scales were 0.824, 0.930, and 0.890 respectively, indicating strong reliability.

The descriptive findings reveal the sheer ubiquity of social media in adolescent life. WhatsApp was the most widely used application at 83.2 percent, followed closely by Instagram at 81.2 percent. A substantial majority of participants, 73.8 percent, reported engaging with social media for one to five hours daily, a pattern consistent with previously reported global trends and reinforcing the view that digital platforms have become a primary environment for adolescent socialization. Gender differences emerged in platform preferences and behaviors: girls were significantly more likely to use Snapchat, to apply social media effects to their photos, and to care about friends’ opinions regarding shared photos. While 72.6 percent of adolescent girls indicated that peer feedback on their visual content mattered to them, only 38.0 percent of boys said the same.

The central statistical finding concerns social appearance anxiety, defined as the anxiety and stress experienced during the evaluation of one’s appearance by others. The mean social appearance anxiety score for girls was 38.1, significantly higher than the boys’ mean of 30.8. In the multiple linear regression model examining predictors of social appearance anxiety, the model was statistically significant and accounted for 26.4 percent of the variance. Three independent variables emerged as significant: being male was associated with lower anxiety, increasing age was associated with decreasing anxiety, and continuity of social media use was associated with increasing anxiety, with a coefficient of 0.963 and a 95 percent confidence interval of 0.520 to 1.406. This finding suggests that the habitual, always-on nature of social media access, rather than mere technical proficiency with digital devices, is what drives the psychological burden.

Correlation analysis further illuminated the web of relationships among the study variables. Social appearance anxiety was positively correlated with social media use continuity, eating restraint, shape and weight over-evaluation, body dissatisfaction, binging, purging, and overall eating disorder risk. The strongest correlations were with shape and weight over-evaluation and body dissatisfaction, both exceeding 0.43. Social media continuity itself was positively correlated with shape and weight over-evaluation, body dissatisfaction, and eating disorder risk. These bivariate associations paint a coherent picture: adolescents who remain continuously connected to social media report greater dissatisfaction with their bodies and more disordered eating attitudes.

However, the multivariate regression analysis for eating disorder risk revealed a more nuanced mechanism. The model accounted for 29.6 percent of the variance in eating disorder risk, but the direct effect of social media continuity dropped below statistical significance once social appearance anxiety was included. Instead, two independent variables remained significant: social appearance anxiety, with a coefficient of 0.068 and a 95 percent confidence interval of 0.053 to 0.083, and body mass index-for-age percentile, with a coefficient of 0.019. This pattern suggests that the observed risk is primarily driven by underlying psychological constructs rather than by social media use itself. The researchers interpret this as evidence that social appearance anxiety functions as the proximal psychological pathway through which continuous digital exposure translates into disordered eating attitudes.

The theoretical framework underlying these findings draws on body image theories, which hold that the media transmits social appearance ideals through which pressures regarding appearance are placed on individuals and comparisons are made. Social media users compare their own appearance with that of others and may edit their photos, generating negative thoughts about body image and body dissatisfaction. Body dissatisfaction, in turn, forms a basis for the development of eating disorders. The relationship may also be bidirectional: adolescents heavily exposed to idealized visual content may develop body image anxiety, while those with high body image anxiety may use social media as a tool to seek approval and attention regarding their appearance. The cross-sectional design prevents the establishment of causality, but the findings suggest that continuity of social media use and concerns about social appearance are mutually reinforcing factors that may trigger eating disorder risk through this process.

The broader epidemiological context amplifies the urgency of these results. Eating disorders are chronic and treatment-resistant physical and mental illnesses with high mortality rates, affecting all age groups, ethnicities, body sizes, socioeconomic statuses, and religions regardless of sex. Between 1999 and 2022, 22.36 percent of children and adolescents were reported to have disordered eating, and the incidence of eating disorders has increased over the last 40 years in parallel with the rise of social media use among adolescents. The present study also found that increasing body mass index-for-age percentile was associated with increased eating disorder risk, consistent with previous research by Flament and colleagues linking weight status to eating disorder diagnoses in community adolescents.

The authors acknowledge several limitations that temper generalization. The study was conducted in only one city and two high schools, potential confounding factors such as depression, anxiety disorders, self-esteem, and socioeconomic status were not examined, and the explanatory power of the regression models remained relatively limited. Pubertal development stages were not objectively determined, and body dissatisfaction was not directly assessed. Nevertheless, the conclusions carry practical weight. The researchers recommend designing social media literacy education programs for adolescents, organizing school activities to raise awareness, creating environments for face-to-face communication, and developing national policies aimed at conscious social media use. Educating adolescents about social media use and monitoring their usage, they argue, may be associated with a potential reduction in eating disorder risk and related health problems in the long term.

The research team enrolled 250 students, 113 boys and 137 girls aged 11 to 17, drawn from secondary education and the first year of Baccalaureate. The study used a quasi-experimental design with non-equivalent groups. One hundred twenty-one students were assigned to the experimental group, which completed seven one-hour sessions embedded within Physical Education classes. These sessions combined body expression activities, essentially structured movement and improvisation exercises designed to build comfort and familiarity with one’s own body, with targeted exercises aimed at raising awareness of online gendered body stereotypes. The remaining 129 students formed an active control group that attended informational lectures on related topics instead.

The technical logic of the design matters. Because both groups received some form of attention and content, the comparison tested not simply whether any intervention helps, but whether the specific blend of embodied movement and digital-stereotype awareness outperforms a more conventional didactic approach. The researchers measured three psychological variables before and after the program: internalization of gender-specific body ideals, meaning the degree to which students personally endorsed thinness ideals for girls and muscularity ideals for boys; social appearance anxiety, the fear of being negatively judged on one’s looks; and symptoms of disordered eating. Standardized psychometric instruments were administered at both time points, allowing the team to compute changes within each group and, critically, group-by-time interaction effects.

The baseline data painted a familiar but sobering picture of adolescence in the digital era. Girls reported significantly higher media pressure than boys, consistent with a large body of research showing that girls absorb more appearance-related messaging and face more intense scrutiny of their bodies online. Perhaps more striking, boys were far from immune: students of both genders reported that their primary motivation for exercise was to modify their appearance rather than to build fitness, health, or enjoyment. This finding underscores how deeply appearance-driven reasoning penetrates adolescent physical activity, shaping behavior in ways that can undercut the very health benefits exercise is supposed to provide.

After the intervention, the results were encouraging, though with an important twist. Both the experimental group and the active control group showed statistically significant improvements across the measured variables. Students in both conditions reported reduced internalization of gendered body ideals, lower social appearance anxiety, and fewer eating disorder symptoms. However, the analysis found no significant group-by-time interaction effects. In plain terms, the carefully constructed combination of body expression and digital literacy work did not outperform the simpler lecture-based format in this sample. Both pathways appeared to move the needle by roughly similar amounts.

The researchers are careful in their interpretation, and the honesty of that interpretation is itself notable. The RealBody+ program was associated with improvements in psychological aspects of body perception, including reduced internalization of gendered body ideals, social appearance anxiety, and eating disorder symptoms. But because the changes were comparable across both groups, the study cannot claim that the specific active ingredients of the experimental format, the movement work or the stereotype-awareness exercises, were uniquely responsible. It is possible that simply dedicating structured classroom time to talking about bodies, media, and health produces most of the benefit, and that the precise format matters less than educators have assumed.

That conclusion carries real practical weight. School-based body image interventions have historically struggled with scalability. Programs requiring trained specialists, extended curricula, or costly materials face steep barriers to adoption, particularly in under-resourced schools. If a lecture-based format delivered within existing Physical Education time produces comparable gains to a more elaborate program, schools have a cheaper, more flexible menu of options. Conversely, if future research shows that the experimental format shines under different conditions, for example with longer follow-up, different age bands, or students with higher baseline risk, the movement-based approach may still earn its place. The current study, by including an active rather than passive control group, set a demanding bar for itself.

The broader scientific context reinforces why this line of work matters. Decades of research have linked internalization of thin and mesomorphic ideals to disordered eating, compulsive exercise, depression, and social withdrawal in adolescents. The rise of image-centric social media has intensified these pressures: content analysis studies of fitspiration imagery, selfie-editing behavior, and appearance-focused platforms document a steady stream of gendered body messaging that adolescents consume daily. Objectification theory provides the dominant explanatory framework, holding that internalizing an observer’s perspective of one’s own body fosters habitual body monitoring, appearance anxiety, and, downstream, risky eating and exercise behaviors. Girls appear to absorb more of this pressure on average, but the Granada baseline data on appearance-driven exercise motivation among boys confirms that muscularity ideals now exert a parallel toll.

What distinguishes RealBody+ from many predecessors is its dual-channel design. Rather than treating body image as purely a matter of cognition, something to be corrected with facts and counter-arguments, the program also engages the body directly through expression activities. The rationale draws on pedagogical traditions in physical education that view embodiment, comfort with movement, and non-verbal self-expression as protective resources. At the same time, the digital literacy component acknowledges that the primary delivery system for harmful body ideals today is the smartphone screen, not the magazine rack. Teaching students to name and critique online gendered body stereotypes is, in effect, an inoculation strategy against the media environment they inhabit.

For now, the headline finding is both modest and useful: two different school-based approaches, one embodied and digitally critical, one informational, both produced significant short-term reductions in the psychological risk factors that precede eating disorders and body dissatisfaction. The study was supported by the University of Granada, the Spanish Ministry of Universities, and Spanish research excellence programs, and was approved by a local ethics committee in accordance with the Declaration of Helsinki. The authors note no conflicts of interest. Whether the gains persist, and whether combining the two formats yields additive benefits, remain open questions for future trials. But for schools searching for feasible ways to defend their students’ mental health against the pressures of the feed, the message from Granada is that structured classroom time spent on bodies, media, and health, in almost any thoughtful form, is time well spent.

The measurement toolkit used in the study reflects the standard instruments of the field. Eating disorder symptoms were assessed with the Eating Disorder Examination Questionnaire, a widely validated self-report measure originally developed by Fairburn and Beglin, while self-esteem was captured with the Spanish adaptation of the Rosenberg scale. Prior Spanish validation work on body esteem and appearance anxiety measures in adolescent samples has made such cross-sectional assessment feasible in school settings, which is one reason Spain has become an active site for preventive body image research.

The study also sits within a growing international evidence base. Comparable classroom programs, such as the five-session teacher-delivered body image curriculum evaluated in a cluster randomized trial and brief digital-literacy interventions tested with adolescents in the United Kingdom, have similarly reported reductions in body dissatisfaction when embedded in normal school timetables. The Spanish team’s choice of an active control group mirrors the methodological caution seen in these trials, where attention effects and simple psychoeducation often account for more benefit than researchers initially expect.

Several limitations temper the findings. The quasi-experimental design with non-equivalent groups means students were not randomly assigned, leaving open the possibility of baseline differences between conditions that influenced the pattern of change. The absence of a long-term follow-up assessment also means the durability of the improvements, whether students maintained lower appearance anxiety and fewer disordered eating symptoms months later, cannot yet be judged. Sample composition, drawn from Spanish secondary schools and spanning a wide age range from 11 to 17, may mask developmental differences in how younger and older adolescents respond to stereotype-awareness content.

Even so, the consistency of improvement across both conditions strengthens the case that schools can serve as effective delivery platforms for preventive mental health work, particularly when sessions fit within existing curricular structures rather than competing with them.
