The intervention effect is defined as the intervention minus usual care difference in the change in score from baseline.
Differential effect defined as the intervention effect in the less advantaged group minus the intervention effect in the more advantaged group. Differential effects<0 indicate greater reductions (from baseline) in scores in the less advantaged group than in the more advantaged group.
