title: Evaluation of a modified contingency management intervention for consistent attendance in therapeutic workplace participants.
abstract: In a therapeutic workplace business, drug abuse patients are hired as data entry operators and paid to perform data entry work contingent upon documented drug abstinence. Reliable attendance has been difficult to maintain despite the opportunity for operators to earn a living wage, 6 h per day, 5 days per week. A within-subject reversal design experiment evaluated a contingency management intervention that allowed for flexibility regarding when operators could arrive to work, yet maintained a contingency for reliable workplace attendance. Results from a within-subject reversal design experiment demonstrated the contingency management intervention to be effective in increasing the frequency of completed work shifts in four of five operators. Repeated measures ANOVA and Tukey's post-hoc tests of grouped data showed that the contingency management intervention significantly (P < 0.05) increased the mean percent of days that operators completed work shifts (5% baseline; 63% contingency management; 7% baseline). This study demonstrates an effective procedure for maintaining attendance in therapeutic workplace participants.
