Note: p-value for Stage change is from two-sided Fisher exact test for collapsed variable into three categories (-2/-1/0 vs. 1 vs. 2/3). P value for forward stage movement is for forward (1, 2, 3) vs backward or stay the same, regarding stage change from baseline to 6 month interview (-2/-1/0). The sample size for stage changes at 6 months (T3) are Intervention (n=80) and Usual Care (n=65).
