Note. N = 163. HB = health behavior. T1/T2 = first/second point of measurement. B = unstandardized regression coefficient. SE = standard error. β = standardized regression coefficient. UB = unhealthy behavior. HB at T1 corresponds to the behavior represented in each column. Social tie's influence for unhealthy behavior refers to the corresponding participant behavior. ap < .05, bp < .01.
