A study involving a simple random sample of 180 county-level administrators employed by the U.S. Cooperative Extension Service assessed the effects of client and administrator involvement as stakeholders in evaluation. A posttest-only control group design was used. Variables included level of administrator involvement as stakeholders and level of client involvement as stakeholders. Each subject was assigned to one of nine treatment groups, reflecting nine permutations of a simulated evaluation report. The instrument was administered via the mail. Three mailings of the questionnaire booklet and follow-up postcards resulted in a final response rate of 94%. Results indicate that: (1) involvement of administrators had no direct effect on administrators' readiness for evaluation utilization; (2) perceptions of technical adequacy, increased stakeholder participation, and the perceived quality of the report were substantially related to utilization readiness; (3) attitude toward evaluation and readiness for evaluation utilization were significantly related; (4) the relationship between attitude toward evaluation and training in evaluation was negligible; and (5) a significant portion of the variance in readiness for utilization was explained by the variables in the generated model. Two flowcharts and one bar graph are included. (TJH)
