The purpose of this research project was to investigate the utility of the genogram and eco-map as family assessment tools for working with American Indian vocational rehabilitation (VR) clients who are referred for rehabilitation services, and to describe changes in the family system after VR services have been delivered by evaluating information in the genogram and eco-maps at the initiation and end of service. The project involved a comprehensive literature review, training of VR counselors about the family assessment tools, and implementation of the instruments. Four state and three tribal VR counselors who participated in a training workshop focused on the theory and application of the family assessment instruments. The counselors then completed a total of 15 genograms and 16 eco-maps. The genograms gathered information including: age, sex, marital status, ethnicity, educational status, religion, employment, and social and medical conditions. The eco-maps obtained such data as sex, number of children, informal support systems, friends, recreation, ceremonial and formal support systems, education and employment services, social services, rehabilitation, medical services, and legal systems. A survey of the counselors found that the tools took too much time to administer and were more appropriate for intensive therapeutic interventions instead of vocational rehabilitation services, and that the genogram was too intrusive a data gathering instrument to use early in a beginning relationship.
