NOTE. Values are presented as mean ± standard deviation.

^†P overall is the effect of repeated measures mixed model; P1, P2, and P3 is the effect of intervention at each time and in each group with contrast command. P1 compares the pre- and posttest in the control group, P2 compares the pre- and posttest in the intervention group, and P3 compares the posttest between control group and intervention group.

^‡Score ranges from 0 to 42.

^§Score ranges from 34 to 170. ASPS has the 5 dimensions. Dimension 1 is “risk perception,” 5 items, score ranges from 5 to 25; dimension 2 is “efficacy of SPs,” 8 items, score ranges from 8 to 40; dimension 3 is “barriers to implementing SPs,” 8 items, score ranges from 8 to 40; dimension 4 is “favorable conditions for action,” 8 items, score ranges from 8 to 40; and dimension 5 is “assessment of self-efficacy,” 5 items, score ranges from 5 to 25.

^||Score range from 20 to 80.
