The attendance rates of welfare recipients at self-help group meetings was compared when supplementary reinforcement was given for attending and when it was not. Reinforcers included donated items, such as clothing and household goods, and information about welfare services. It was found that the attendance at meetings averaged three recipients per meeting without reinforcement and 15 recipients per meeting with reinforcement. There was evidence that attendance was associated with participation in other self-help activities. It was concluded that practical forms of reinforcement can be found to maintain the participation of severely disadvantaged populations in self-help groups.
对有附加强化（强化物包括捐赠物品，如衣物和家居用品，以及有关福利服务的信息）和没有附加强化时福利接受者参加自助小组会议的出勤率进行了比较。结果发现，没有强化时每次会议平均有 3 名参加者，有强化时每次会议有 15 名参加者。有证据表明，出勤率与参加其他自助活动有关。结论是，可以找到实际的强化形式来维持处境极为不利的人群参与自助小组。
