Efficacy Potential
Efficacy potential refers to the intervention’s promise for effectiveness with the intended population In repeated measures multivariate analysis, change in all outcomes from baseline to 6 and 12 months was positive (Pillai’s trace criterion, F[18, 24]= 3.64, p= .002) with
a partial effect size h2= .73 and a power of .99, supporting the underlying theory of the New Brunswick Intervention for Health Enhancement After Leaving (see Table 4).
