This report is a summary of the functional analysis of the activities of those engaged in social service occupations in medical settings, which was conducted as part of the UCLA Allied Health Professions Project. A task inventory composed of 192 tasks relating to intake, information and referral, treatment, supportive, community and administrative services was developed and submitted to a representative sample of hospitals in six geographic regions. Responses from 148 persons employed in social services departments revealed that: (1) The community services function was performed least by the social service workers; and (2) Many more similarities than differences were discovered among aides, social work assistants, and social workers with the master's degree (MSW) in both task performance and frequency of task performance. It was recommended that aides be given training to help them perform the higher order treatment functions they are already required to perform and that MSWs receive intensive training in supervision of personnel management, performance evaluation, and task delegation. A copy of the survey questionnaire and other study material are appended. (SB)
