Changes in unadjusted OMS-HC scores according to intervention group, by study interval
T2-T1 n = 90 T3-T1 n=96 T3-T2 n=96 T4-T1 n= 50 T4-T3 n=50
All participants -0.4 (-1.0, 0.3) p = 0.374 -4.4 (-5.8, -3.1)* p<0.0001 -4.2 (-5.6, -2.9)* p<0.0001 -3.4 (-5.9, -1.9)* p = 0.0002 1.0 (-0.2, 2.2) p = 0.10
Intervention group 0.3 (-0.5, 1.0) p = 0.67 -4.2 (-6.4, -2.0)* p<0.0001 -4.6 (-6.6, -2.7)* p<0.0001 -3.6 (-6.5, -0.8)* p = 0.0148 1.5 (-0.3, 3.3) p = 0.06
Control group -1.0 (-2.2, 0.1) p = 0.05 -4.6 (-6.4, -3.0)* p<0.0001 -3.9 (-5.7, -2.0)* p=0.0002 -3.2 (-7.1, -1.3)* p = 0.006 0.5 (-1.3, 2.3) p = 0.58

T1 = baseline; T2 = following the intervention; T3 = following the course; T4 = 3 month follow-up. Negative scores denote a decrease in stigma; change score (95% CI), p-value.

*= Statistically significant, based on one-sample t-tests (where Ho: change=0 and α = 0.05).
