This report describes the important contribution that Retired Senior Volunteer Program (RSVP) Volunteers are making to help reduce alcohol and drug abuse. ACTION undertook a study of the Retired Senior Volunteer Program's activities in alcohol and drug abuse prevention and education. The study had two major goals: to provide descriptive information based on RSVP Projects, Stations, and Volunteers and on the effects of RSVP activities; and to describe successful activities and program elements that ACTION can use to construct models for others to follow and adapt. The study used mail and telephone surveys to collect data on activities in RSVP Projects and Volunteer Stations. Based on the findings, researchers then chose three sites for more intensive on-site data collection. Project Directors of 752 (99%) of the 761 RSVP Projects completed the survey. Site visits were conducted with three exemplary Volunteer Stations to collect in-depth information. The survey results indicated that: (1) RSVP Volunteers' services include direct and indirect services, prevention, education, and treatment in the area of alcohol and drug abuse; (2) recruitment to alcohol and drug abuse areas is more demanding, and training requires more attention, than other RSVP activity areas; (3) Station Supervisors find RSVP Volunteers capable, dependable, and willing to serve; and (4) opportunities exist for increased participation in alcohol and drug abuse prevention activities. Information on what the model sites can teach and program recommendations are included. The appendices, separately bound, contain: the scope of the study; the volunteer supervisor, the project director, and the station director survey instruments; the research methodology; and extensive data tables.
