The present study demonstrates the effectiveness of combining medication packaging, verbal and graphical feedback, and pill count probes on increasing medication compliance. Eight chronic adult outpatients were randomly assigned to one of two conditions: (a) a regimen card medication packaging system, and (b) a 7- day baggie medication packaging system. A staggered group treatment design was used to ascertain whether either of the two special packaging systems was effective relative to baseline and reversal conditions (using the standard medication vial) in increasing medication compliance behavior among both over-and undercompliant outpatients. Results indicated that the use of the special packaging of medication in combination with the behavioral techniques of verbal and graphical feedback aided in improving compliance in 4 out of 8 noncompliant outpatients.
