The research is anchored in a classic framework from environmental psychology known as Stimulus–Organism–Response, or S–O–R, first proposed by Mehrabian and Russell in the 1970s to explain how environmental cues trigger internal emotional states that then drive behavior. The Indian team extended this model into the digital marketplace. In their formulation, two antecedent conditions feed into the consumer’s internal evaluation stage. The first is Consumer Social Responsibility, an enduring personal orientation reflecting a person’s recognition that their consumption choices carry social and environmental consequences. The second is Sustainability-Related Social Media Influence, the informational and social pressure arising from sustainability content, recommendations, and discussions encountered on platforms such as Instagram, YouTube, and LinkedIn. Both stimuli, the researchers hypothesized, would shape two internal evaluations—Green Trust, the confidence a consumer places in environmental claims and product performance, and Green Perceived Value, the judged worth of a sustainable product’s environmental benefits relative to the sacrifices of buying it—which would in turn drive Purchase Intention.

To test this architecture, the team ran a quantitative, cross-sectional survey across Chennai, Bengaluru, and Hyderabad, targeting consumers aged 18 to 29 who used social media and had encountered sustainability-related content. Of 400 questionnaires distributed through WhatsApp groups, social media networks, university channels, and professional networks, 347 complete responses were retained, distributed almost evenly across the three cities. The sample skewed female at 59.9 percent, was dominated by undergraduates at 67.1 percent, and was heavily engaged online: Instagram was the primary platform for 32 percent of respondents, YouTube for 28 percent, and LinkedIn for 25.6 percent, with nearly a third spending three to four hours daily on social media. A pilot study with 126 respondents—excluded from the final analysis—confirmed the reliability of the measurement scales, with Cronbach’s alpha coefficients ranging from 0.746 to 0.914 across the five constructs.

The analytical pipeline was rigorous. Exploratory Factor Analysis using Principal Axis Factoring with Varimax rotation produced a clean five-factor solution, with loadings ranging from 0.568 to 0.934 and no substantial cross-loadings. Confirmatory Factor Analysis then validated the measurement model with strong fit indices: a normed chi-square of 2.749, a Comparative Fit Index of 0.953, and a Root Mean Square Error of Approximation of 0.071. Reliability coefficients for all constructs exceeded the conventional 0.70 threshold, and discriminant validity was confirmed using the Fornell–Larcker criterion, with the square roots of average variance extracted for each construct exceeding all inter-construct correlations. Harman’s single-factor test indicated that common method bias was not a serious concern, with the first factor explaining only 27.1 percent of the variance, well below the 50 percent warning threshold.

With the measurement model secured, the researchers turned to Structural Equation Modeling to test the hypothesized pathways, employing bias-corrected bootstrapping with 5,000 resamples to evaluate indirect effects without assuming normality. The structural model fit the data acceptably, with a chi-square to degrees of freedom ratio of 3.729, a CFI of 0.926, and an RMSEA of 0.079. The results revealed a striking asymmetry between the two antecedents. Consumer Social Responsibility was significantly and positively associated with both Green Trust (β = 0.264, p < 0.001) and Green Perceived Value (β = 0.174, p = 0.008). Sustainability-Related Social Media Influence, by contrast, was positively associated with Green Trust (β = 0.130, p = 0.045) but showed no significant relationship with Green Perceived Value (β = −0.079, p = 0.254). In other words, scrolling past sustainability content may convince young consumers that green products are credible, but it does not make them value those products more.

The pathways to purchase intention proved equally revealing. Green Trust showed a significant positive association with Purchase Intention (β = 0.256, p < 0.001), confirming that confidence in environmental claims reduces uncertainty and strengthens the willingness to buy. But Green Perceived Value produced an unexpected and statistically significant negative association with Purchase Intention (β = −0.133, p = 0.027)—a result that contradicts the predominantly positive relationships reported in prior literature. The researchers probed this anomaly carefully. The zero-order correlation between the two variables was weak and non-significant (r = −0.040, p = 0.462), yet the negative coefficient emerged robustly in the multivariate model, a pattern consistent with statistical suppression. Collinearity diagnostics showed no problematic multicollinearity, with tolerance values ranging from 0.710 to 0.855 and variance inflation factors all below 1.5. The authors caution that this negative relationship is an empirical finding requiring investigation rather than a settled causal interpretation, and they explicitly note that their study does not directly test the mechanisms underlying it.

The mediation analysis, the statistical heart of the study, delivered the most consequential verdict. Consumer Social Responsibility exerted a significant indirect effect on Purchase Intention through Green Trust (β = 0.068, 95% bias-corrected confidence interval [0.019, 0.095], p < 0.001), and also through Green Perceived Value (β = −0.023, 95% CI [−0.050, −0.001], p = 0.038), though the latter pathway operated through the negative value-to-intention link. Meanwhile, neither mediator carried a significant indirect effect from Sustainability-Related Social Media Influence to Purchase Intention: the Green Trust pathway yielded β = 0.033 (p = 0.109) and the Green Perceived Value pathway yielded β = 0.011 (p = 0.207), both statistically indistinguishable from zero. Notably, the direct paths from both antecedents to Purchase Intention were also non-significant, indicating that Consumer Social Responsibility works on purchase intentions almost entirely through the internal evaluations of trust and perceived value rather than through any direct route.

The explanatory power of the model, while modest, tells its own story. The constructs explained 11.2 percent of the variance in Green Trust, 2.6 percent in Green Perceived Value, and 8.0 percent in Purchase Intention—figures that underscore how much of sustainable purchasing psychology remains uncharted. This is not a failure of the model so much as a reminder that purchase intentions among young consumers are shaped by a vast array of factors beyond responsibility and social media exposure, including price sensitivity, product availability, habit, and cultural context. The authors are careful to frame their findings as associations consistent with the S–O–R framework rather than evidence of causal direction, given the cross-sectional design and the non-probability purposive sampling method, which may limit generalizability beyond the studied population.

For businesses targeting Generation Z, the practical implications are pointed. The findings suggest that sustainability communication should emphasize consumers’ own environmental responsibility and the credible trustworthiness of green claims, rather than assuming that a heavier volume of social media content will automatically elevate how valuable young consumers perceive sustainable products to be. Because social media influence built trust but not perceived value, and because trust—not value—was the reliable engine of purchase intention, brands may get more return from transparent, verifiable sustainability communication than from promotional messaging about environmental benefits. The unexpected negative association between Green Perceived Value and Purchase Intention adds a further caution: recognizing that a product is environmentally beneficial does not necessarily mean a young consumer intends to buy it, particularly when other considerations compete in the decision.

The study also opens clear avenues for future research. The authors call for longitudinal or experimental designs to untangle the direction of causality, including the possibility that trusting green products may itself foster a stronger sense of consumer responsibility rather than the reverse. Replication across different geographic settings, consumer groups, and sustainable-product categories would test whether the negative Green Perceived Value finding is an artifact of this particular sample or a genuine feature of how young consumers weigh environmental benefits against the sacrifices of green purchasing. The researchers also acknowledge that conducting exploratory and confirmatory factor analyses on the same sample, rather than independent datasets, is a methodological limitation that future work should address. What the study establishes firmly, however, is that in the contest for Generation Z’s green wallets, the loudest voice on the feed may matter less than the quiet conviction, formed within each consumer, that sustainable products can be trusted to deliver what they promise.

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.
