Initiative Description: Students were randomized to an intervention group (n=24) or a wait-list control group (n=13). The intervention consisted of an organization intervention and a homework management intervention, which were delivered on Tuesdays and Thursdays for 8 weeks after school. Lessons lasted for 75 minutes. All students received 20 minutes of individual intervention time and 55 minutes of group intervention each program day. Students returned to the after school program on one additional occasion for follow-up evaluation, 8 weeks after the completion of the intervention. The wait-list control group received the same 8-week intervention after the intervention group completed the intervention.
Study Results: Participants made significant improvements in organization and homework management skills during the intervention and these gains were maintained at 8 weeks follow-up.
