Bayes factors qualified the indirect effect paths as moderately supported by the data for drive for thinness and for body dissatisfaction (BFten = 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•b2 = 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 power analysis to own mediation shown our very own sample reached enough electricity: .86 and you will .79 to possess drive for thinness and the body frustration balances, respectively.
six.step three Serial mediation analyses
We examined the latest secondary effects of Instagram-pictures pastime on drive to have thinness and the entire body disappointment courtesy physical appearance-relevant evaluations into the Instagram and you can from internalization as well as charm standards (Shape 2a).
As regards drive for thinness, Instagram-photo activity was positively associated with appearance-related comparisons on Instagram, a1 = 0.31, SE = 0.several, 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 Carlo fuel study to possess serial mediation models showed that our take to attained sufficient strength: .93 and you may .94 having drive to own thinness and the body disappointment balances, respectively.
seven Discussion
In this analysis, we replicated the outcomes of Study step 1: appearance-relevant reviews toward Instagram mediated this new relationship between Instagram-photographs passion and one another push for thinness and the entire body frustration. More over, Studies San Bernardino escort service 2 showed that Instagram-pictures activity is linked to each other push having thinness and the body frustration primarily owing to physical appearance-related reviews into Instagram and internalization out of beauty conditions (Hypotheses 4a and you can 4b). Together, this type of findings showed that women that has even more serious Instagram-photographs interest was basically likely to firmly engage in physical appearance-related comparisons, which in turn have been for the enhanced amounts of body questions. It development of performance try confirmed once we estimated a beneficial serial mediation design to possess drive for thinness and body disappointment additionally.
