Motivating adolescents to reduce their fines in a token economy.

Adolescents on a 16-bed token economy ward of a state hospital were subjected to four interventions in a seven-phase experiment to reduce the number of fines they received each day. Phase I was a four-week baseline period. Phases II and III were four- and five-week periods, respectively, in which residents were awarded tickets for a weekly $10 lottery each day they were at or below a changing criterion of daily fines. In Phase IV, residents received coupons, exchangeable for money, for days with zero fines. Phase V was a return to baseline. Phase VI was a one-week period in which daily lotteries for $1 were held, with the criterion for receiving a ticket being zero fines on the previous day. Phase VII was a one-week return to baseline. No significant differences in average fines per day, number of residents meeting criteria, or mean number of zero-fine days per week were found across phases. Results are discussed in terms of amount and immediacy of reinforcement, other opportunities to gain money, possible rebelliousness of the residents against the increased aversiveness of fines, and implications for further research.
