*Min-max subscales: 0–15 (general), 0–42 (environmental), 0–45 (attitudinal), and 0–102 (total)
^‡Effect size (ES) of change was calculated as mean change from baseline divided by the standard deviation of change. Criteria: trivial 0 to < 0.20; small 0.20 to < 0.50; moderate 0.50 to < 0.80; and large ≥ 0.80
