Bayes factors qualified the indirect effect paths as moderately supported by the data for drive for thinness and for body dissatisfaction (BF_ten = 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•b_dos = 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).

An article-hoc Monte Carlo power study to own mediation indicated our sample attained enough strength: .86 and .79 to have drive to have thinness and the body dissatisfaction balances, correspondingly.

6.3 Serial mediation analyses

I checked-out this new secondary negative effects of Instagram-photo hobby on drive to own thinness and body disappointment courtesy appearance-relevant reviews with the Instagram and you may through the internalization as well as beauty requirements (Contour 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, b_eleven = 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, b_twenty-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 Carlo energy study to own serial mediation designs revealed that the shot hit adequate strength: .93 and you may .94 having push to possess thinness and body disappointment balances, respectively.

In this study, i replicated the outcomes regarding Research step 1: appearance-associated reviews toward Instagram mediated the newest connection ranging from Instagram-images interest and you may each other drive to own thinness and body disappointment. Moreover, Research dos revealed that Instagram-photographs activity is actually regarding one another drive having thinness and the entire body frustration mostly thanks to looks-related comparisons into the Instagram and you will internalization from beauty conditions (Hypotheses 4a and you will 4b). With her, this type of conclusions demonstrated that women who had alot more extreme Instagram-images passion were prone to strongly take part in physical appearance-associated contrasting, which in turn was indeed regarding the increased degrees of human body questions. So it trend out of performance is affirmed when we projected a great serial mediation design having push having thinness and the entire body dissatisfaction in addition.
