Pharmacist and physician attitudes were surveyed approximately 1 year after the implementation of Florida's drug product selection legislation. It was not possible to identify a consistent relationship between the attitudes of prescribers and pharmacists and subsequent drug product selection behavior, even though pharmacists were generally in favor of the law and physicians opposed it. However, neither saw the law as weakening their professional relationships. Both groups seemed to overestimate the degree of drug product selection activity actually occurring. From a methodological perspective, this suggests that a survey questionnaire approach to estimating these rates may not be valid.
