aPost hoc two sample t tests detected significant differences (p < .05) between intervention and control groups at visits 2, 3, 4
bPost hoc paired t tests detected significant increases (p < .05) within intervention group between visit 1 and visits 2, 3 and 4
cPost hoc paired t tests detected a significant decrease (p < .05) in transformed behavior risk score between visit 1 and visit 4
