Data were obtained from three sources--survey of law enforcement agencies in Ohio, the Federal Bureau of Investigation, and the U.S. Bureau of Census--as part of a larger evaluation of the organization and effectiveness of Ohio's multi-jurisdictional task forces. Logistic regression analysis indicated the main independent variable of the research, task force membership, was statistically significant. Task force members reported communicating with other criminal justice agencies more times over a 6-month period than non-task force agencies. Further, task force membership was significantly related to ratings of the quality of drug cases. Task force membership was not a significant predictor of total drug arrests or arrests for the sale of drugs. Population heterogeneity of the jurisdiction was the only significant predictor of drug arrests. The authors conclude task force membership impacts perceptions but does not appear to influence objective measures of drug law enforcement outputs. 57 references, 7 notes, and 5 tables
