  1. aReliability study sample (n = 166); bItems were coded such that a high score = perceptions of a highly supportive environment; T1 = survey time point 1, T2 = survey time point 2, SD = standard deviation; ICC = Intraclass correlation coefficient; all ICCs presented p < 0.001 for difference from zero.
