Two experiments were conducted to compare the effects of several prompting and reinforcement procedures on the participation of elderly citizens in a nutritious meal program. Experiment I employed a variation of the multiple-baseline design across three groups of approximately 60 households each. Elderly persons not previously participating in the program were introduced to the following conditions: (1) public service radio announcements for four weeks to advertise the meal program and the availability of free transportation, (2) a home visit that served as a personal invitation and a second prompt for participation, (3) a followup telephone call, and (4) an incentive menu for participation, which was sent through the mail. Results indicated that the home visits and incentives were both effective as recruitment procedures and superior to other conditions; however, incentives proved to be the most cost-effective intervention. Experiment II used a variation of the multi-element design to compare the effects of scheduled activities and incentives in maintaining higher levels of participation by those persons who had attended the meal program at least once in the past, but whose current rate of participation was low. Results showed that activities improved attendance levels somewhat and that incentives substantially increased the number of meal program participants. Data from these experiments thus indicate that relatively inexpensive procedures may be used effectively to increase the extent to which elderly persons make use of potentially beneficial community-based services.
两项实验旨在比较几种提示和强化程序对老年人参与营养膳食计划的影响。实验一采用了跨三组的多个基线设计,每组约有 60 户家庭。以前未参与该计划的老年人被引入以下条件:(1)公共服务广播公告持续四周,宣传膳食计划和免费交通的可用性,(2)家访作为参与的个人邀请和第二次提示,(3)后续电话,以及(4)参与的激励菜单,通过邮件发送。结果表明,家访和激励措施都是有效的招募程序,优于其他条件;然而,激励措施被证明是最具成本效益的干预措施。实验二采用多元素设计的变化,比较了有计划的活动和激励措施对那些过去至少参加过一次膳食计划但目前参与率较低的人保持更高参与水平的影响。结果表明,活动在一定程度上提高了出勤率,激励措施则大幅增加了膳食计划参与者的数量。这些实验的数据表明,相对廉价的程序可以有效地用来增加老年人利用潜在有益的社区服务的程度。
