Effects of control and predictability on the physical and psychological well-being of the institutionalized aged.
It was hypothesized that some of the characteristics frequently observed among the aged--such as feelings of depression and helphlessness, as well as accelerated physical decline--are at least in part attributable to loss of control. A field experiment in which institutionalized aged were randomly assigned to one of four conditions was carried out to assess the effects of increased control and predictability upon the physical and psychological well-being of the aged. Individuals in three of the four conditions were visited by college undergraduates under varying contingencies, while persons in the fourth condition were not visited and served as a baseline comparison group. Subjects in the control condition could determine both the frequency and duration of visits they recieved. A second group of subjects (predict) was informed when they would be visited and how long the visitor would stay, but had no control over these details. A third group (random) was visited on a random schedule. It was found that predictable and controllable positive events have a powerful positive impact upon the well-being of the institutionalized aged.
