There is limited evidence that contracts can potentially contribute to improving adherence, but there is insufficient evidence from large, good quality studies to routinely recommend contracts for improving adherence to treatment or preventive health regimens.
Increasing attendance at alcohol aftercare using calendar prompts and home based contracting.
The effect of an appointment-keeping intervention on attendance at aftercare was examined for 50 male participants in an inpatient alcohol treatment program. Subjects received either a calendar prompt and home-based attendance contract intervention (Experimental group, N = 25) or standard aftercare treatment arrangements (Control group, N = 25). Participants were followed for eight aftercare sessions over a 6-month period. Results showed significant attendance differences between groups for the first seven aftercare sessions, with nearly twice as many experimental subjects as control subjects attending aftercare sessions. Further, significantly fewer experimental than control subjects (24% fewer) were dropped from the alcohol program for three consecutive nonattendances. The present study provides an effective technology for increasing aftercare attendance and thus potentially increasing the probability of long term maintenance of alcohol treatment effects.
