Assessing the loneliness of workers with mental retardation

This study was designed to determine whether a reliable instrument could be developed to measure the loneliness experienced by workers with mental retardation. In addition, supervisors were asked to rate subjects on loneliness and four other behavioral subtypes in order to determine whether there was a relation between these ratings and the loneliness questionnaire. Three groups of subjects were assessed: persons with mild, moderate, and severe mental retardation. Results indicated that the Worker Loneliness Questionnaire was a reliable instrument for use with persons with mild and moderate mental retardation. In addition, the results showed that some individuals were lonely; however, this was not a pervasive feeling. The implications for measuring the self-perceptions of individuals with mental retardation were discussed.
