Social pharmacology: unresolved critical issues.
This article describes and analyzes decision-making by patients, physicians, and drug information providers about registered medical drugs. Based on a cognitive psychology perspective, cognitive variables (the individual's mediating system) are assumed to be critical factors determining both patient and physician behavior. The individual's psychological functioning is seen as a continuous reciprocal interaction between behavioral, cognitive, and environmental influences; i.e., an interactional paradigm is applied. The importance of research models including cognitive and situation variables to guide the search for appropriate research methods is stressed. An intensive research strategy with a small sample of respondents will often be necessary. Also, respondents should be asked to describe their reactions to specific medical situations. The drug information sender has to select a set of goals for disseminating information to patients. Among the goals most often selected are: message comprehension, receiver satisfaction, changes in knowledge, attitudes, and drug behavior, as well as health effects. More research is needed on how the patient's mediating system, the actual situation, and the perceived situation steer his search for the use of new drug information. A different set of factors influence the patient's decision to start a medicinal or drug treatment than the factors that influence his decision to continue a treatment. The latter factors include forgetfulness, misunderstandings, and the patient's interpretation of physiological signs. More cognitive-oriented research about drug compliance must be undertaken. In such studies the mediating systems of a group of patients could be considered before and after intervention. There are a great number of types of inappropriate (irrational) prescribing. However, a physician may prescribe rationally in one area but irrationally in another. Face-to-face education of physicians has been shown to be effective in reducing inappropriate prescribing in a number of studies. "Overprescribing" of benzodiazepine has been an issue of intensive professional debate during the last decades. The two groups who criticize and defend the existing use of benzodiazepines build their views on different assumptions about the interaction between mind and brain as well as making different value assumptions regarding the use of a psychotropic drug. There is a need for prescription studies where a cognitive and interactional perspective is combined with an information-processing and a normative perspective. The benzodiazepines dependency problem has provoked lively discussion among professionals and the general public. Long-term benzodiazepine use and personality disorders increase the risk of the patient becoming dependent. A great number of research models have been suggested for the analysis of prescription drug dependency and as guides to the treatment of dependency.(ABSTRACT TRUNCATED AT 400 WORDS)
