Bayes factors qualified the indirect effect paths as moderately supported by the data for drive for thinness and for body dissatisfaction (BFstep 10 = 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 blog post-hoc Monte Carlo strength analysis to own mediation indicated our very own try hit adequate electricity: .86 and you may .79 to possess push to have thinness and the body frustration balances, correspondingly.
6.3 Serial mediation analyses
I checked out the brand new indirect outcomes of Instagram-photo activity on drive to have thinness and body dissatisfaction owing to appearance-related contrasting toward Instagram and you may through the internalization and of charm requirements (Figure 2a).
As regards drive for thinness, Instagram-photo activity was positively associated with appearance-related comparisons on Instagram, a1 = 0.31, SE = 0.a dozen, 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).
An article-hoc Monte escort Knoxville Carlo stamina studies to own serial mediation patterns revealed that the shot hit sufficient stamina: .93 and you will .94 for drive to possess thinness and the body frustration bills, respectively.

Within study, i duplicated the outcome of Analysis step one: appearance-associated reviews to your Instagram mediated this new organization anywhere between Instagram-photos passion and both drive to possess thinness and the entire body disappointment. Moreover, Research dos indicated that Instagram-photographs passion is actually pertaining to each other drive getting thinness and the entire body dissatisfaction mainly using appearance-associated evaluations into Instagram and you can internalization out of beauty requirements (Hypotheses 4a and 4b). Together, this type of findings demonstrated that ladies who’d much more extreme Instagram-pictures pastime was likely to firmly participate in physical appearance-relevant comparisons, which often have been in the enhanced degrees of system inquiries. It development of show was affirmed when we estimated good serial mediation model to own drive to possess thinness and the body dissatisfaction as well.
