From: A multi-method exploration into the social networks of young teenagers and their physical activity behavior

  1. Model 1: independent variables (friend group PAQ-C summary mean, best friend’s PAQ-C summary mean, out-degree and in-degree) were investigated as potential predictors of individual PAQ-C summary mean (dependent variable)
  2. Model 2: all four variables added to the model simultaneously
  3. Model 3: adjusted for clustering using STATA version 14.0
