• Long term effectiveness? Most cost-effective measure was the specific prompt group.

Question 7

Which result demonstrates that the intervention groups has a real, measurable impact on adherence?

Answer 7

The study found statistically signficant differences between the intervention groups.

(More parents acted immediately when money was offered)
