Token spending by 20 schizophrenic patients was monitored over a six-month period. It was found that: (1) token expenditures for cigarettes and "edibles" far surpassed other store item categories; and (2) percentage increases in token expenditures were greatest for categories of items relating to appearance and grooming, strongly suggesting that store purchasing patterns over time may provide an index of program effectiveness.
对 20 名精神分裂症患者的代币支出进行了六个月的监测。结果发现：(1) 用于购买香烟和“可食用物品”的代币支出远远超过其他商店物品类别；(2) 与外观和修饰有关的物品类别的代币支出增长百分比最大，这强烈表明随着时间的推移，商店购买模式可能提供计划效果的指标。
