Bayes factors qualified the indirect effect paths as moderately supported by the data for drive for thinness and for body dissatisfaction (BFstep one0 = 7.46, see Data S1). The two indirect effects of Instagram-photo activity on both outcome variables through the mediating role of appearance-related comparisons on Instagram did not significantly differ from each other, a•b1–a•bdos = 0.02, SE = 0.03 and p = .43. The two indirect effects can be constrained to be equally strong without significant loss of model fit (scaled Chi square difference test: ?? 2 = .714, df = 1 and p = .40; difference between Bayesian Information Criterion: ?BIC = 4.09; a•b1 = a•b2 = .16, SE = .06 and p = .01; Figure 1d).
A post-hoc Monte Carlo fuel study to have mediation indicated our try achieved adequate strength: .86 and you can .79 for drive to have thinness and body frustration scales, respectively.
We looked at new secondary outcomes of Instagram-photos interest on drive to possess thinness and the entire body dissatisfaction using physical appearance-relevant contrasting into the Instagram and from internalization as well as beauty conditions (Profile 2a).
As regards drive for thinness, Instagram-photo activity was positively associated with appearance-related comparisons on Instagram, a1 = 0.31, SE = 0.twelve, p = .01. Instagram-photo activity was not associated with the internalization of beauty standards, a2 = ?0.09, SE = 0.1 and p = .43. Appearance-related comparisons on Instagram were positively associated with internalization of beauty standards, d21 = 0.87, SE = 0.09 and p < .001. 12 = 0.44, SE = 0.09 and p < .001, while appearance-related comparisons on Instagram were not associated with drive for thinness, b11 = 0.19, SE = 0.12 and p = .11. The direct effect of Instagram-photo activity on drive for thinness was not significant, c? = ?0.12, SE = 0.12 and p = .29.
According to Hypothesis 4a, the indirect effect of Instagram-photo activity on drive for thinness, first through appearance-related comparisons on Instagram and then, through internalization of beauty standards, was significant, a1•d21•b12 = 0.12, SE = 0.05 and p = .02 (Figure 2b).
As for body dissatisfaction, both appearance-related comparisons on Instagram, b21 = 0.29, SE = 0.10 and p = .003 and internalization of beauty standards, btwenty-two = 0.24, SE = 0.07 and p = .001 were positively associated with body dissatisfaction. The direct effect of Instagram-photo activity was not significant, c? = ?.012, SE = 0.10 and p = .20.
In line with Hypothesis 4b, the indirect effect of Instagram-photo activity on body dissatisfaction, first through appearance-related comparisons on Instagram then through internalization of beauty standards, was significant, a1•d21•b22 = 0.07, SE = 0.03 and p = .04 (see Figure 2b and Data S1 for results concerning other indirect paths).
Internalization of beauty standards had a significantly greater effect on drive for thinness than body dissatisfaction (b12 ? b22 = 0.20, SE = 0.08, p = .01). Parallel mediation paths involving appearance-related comparisons on Instagram and internalization of beauty standards, as well as direct effects of Instagram-photo activity on both outcome variables, could be set to zero (i.e., a2 = b11 = b21 = 0; c? = c? = 0) without any significant loss of model fit (scaled Chi square difference test: ?? 2 = 8.47, df = 5 and p = .13; difference on Bayesian Information Criterion: ?BIC = 14.1; Figure 2c).
A post-hoc Monte Carlo energy data for serial mediation activities showed that all of our test hit enough power: .93 and you can .94 getting push for thinness and the body frustration scales, correspondingly.
In this investigation, i duplicated the outcome out-of Analysis step 1: appearance-related comparisons into the Instagram mediated the brand new relationship anywhere between Instagram-photo passion and you can one another push to have thinness and body frustration. Additionally, Analysis dos revealed that Instagram-photos passion try associated with one another push having thinness and the entire body disappointment generally owing to looks-related comparisons on the Instagram and you can internalization of beauty conditions (Hypotheses 4a and 4b). Together, these findings showed that ladies who had much more intense Instagram-pictures interest was basically expected to firmly do appearance-relevant reviews, which often have been from the increased quantities of body questions. That it development of efficiency was confirmed when we estimated good serial mediation model to have push to possess thinness and the body dissatisfaction while doing so.
