Behavioral contracting was used to encourage physical exercise among college students in a multiple-baseline design. Subjects deposited items of personal value with the experimenters, which they could earn back on fulfillment of two types of contract contingencies. Subjects selected weekly aerobic point criteria, which they could fulfill by exercising in the presence of other subjects. In addition, subjects contracted to observe and record the exercise of other subjects and to perform an independent reliability observation once each week, with both of these activities monitored by the experimenters. Results indicated that the contract contingencies produced increases in the number of aerobic points earned per week for seven of eight subjects, that the aerobic point system possesses several advantages as a dependent variable for behavioral research on exercise, and that inexperienced observers could be quickly trained to observe exercise behavior and to translate those observations into their aerobic point equivalents. Finally, in a followup questionnaire completed 12 months after the end of the study, seven of the eight subjects reported that they were earning more aerobic points per week than had been the case during the baseline condition of this experiment.
在一项多基线设计中，采用行为契约法来鼓励大学生进行体育锻炼。受试者将个人有价值的物品交给实验者，只有在满足两种契约条件时才能取回。受试者选择每周的有氧锻炼积分标准，他们可以通过在其他受试者在场的情况下锻炼来实现。此外，受试者约定观察并记录其他受试者的锻炼情况，并每周进行一次独立的可靠性观察，这两项活动均由实验者监督。结果表明，契约条件使八名受试者中的七名每周获得的有氧锻炼积分增加，有氧锻炼积分系统作为运动行为研究的因变量具有几个优点，并且没有经验的观察者可以很快接受培训，以观察锻炼行为并将这些观察结果转化为相应的有氧锻炼积分。最后，在研究结束12个月后完成的一份后续调查问卷中，八名受试者中的七名报告说，他们每周获得的有氧锻炼积分比本实验基线期时更多。
