Note. Significant effects are bolded. Neg = Negative; Int = Interaction; SM = Social Media; Weekend (1) = Saturday/Sunday; NA = Negative Affect. Risk status is 0 = low risk; 1 = high risk. Percent of Worst or Best Peer interaction reflects the overall percentage of interactions that occurred on social media compared to in-person. Negative Affect represents sustained negative affect, whereas negative emotional reactivity reflects negative emotions during the worst peer interaction on EMA. Degrees of freedom are 105 for between-person (level 2) variables and 1674 for within-person/repeated measures (level 1) variables.
