Bold indicates p < 0.01. ABCD propensity weights were applied based on the American Community Survey from the US Census.
The estimated B coefficent in the cells represents abbreviated output from a series of linear regression models specifying the column header as the outcome variable and the row header as the primary predictor of interest. Thus, the table represents the output from 6 different regression models in total, adjusting for age, sex, race/ethnicity, sexual orientation, household income, parent education, parent marital status, and study site.
^a Asked among a subset who reported social media use (n = 5,642)
^b In Model 3, variance inflation factors were: social media time (1.19) and Social Media Addiction Questionnaire Score (1.17) for both positive and negative expectancies.
