AbstractTo study psychiatrists' decision making between generic and branded antipsychotics or antidepressants a hypothetical decision scenario involving decisions between branded and generic drugs was presented to a sample of German psychiatrists. Factors influencing this decision were identified using a regression analysis. n=410 Psychiatrists participated in the survey. Psychiatrists were more likely to choose branded drugs when imagining choosing the drug for themselves (vs. recommending a drug to a patient). In addition, psychiatrists were more likely to choose generic antidepressants than generic antipsychotics. Additional predictors for choosing a generic drug were a higher share of outpatients, less negative attitudes toward generics and higher uncertainty tolerance. In conclusion, psychiatrists' decision making in choosing between branded or generic antidepressants or antipsychotics is to a large extent influenced by vague attitudes towards properties of generics and branded drugs as well as by "non-evidence based" factors such as uncertainty tolerance.Copyright © 2013.
