Note. Paths a and b are mediation paths. Path c is the direct effect without including the mediator in the model. Path c' is the direct effect after the mediator is included in the model. Addictive Beh. = addictive behavior, S. Identif. = social identification, Psych. Dist. = psychological distress, b = unstandardized regression coefficient, SE = standard error.
