Some investigations suggest that the attitude of a psychiatrist to therapy with drugs may affect his patient's response to treatment (Sheard, 1963; Reynolds, Joyce, Swift, Tooley and Weatherall, 1965), though the evidence is far from conclusive and earlier findings have not always been confirmed by further research (Hordern and Hamilton, 1963; Uhlenhuth and Park, 1964). The possibility that a particular drug may be more effective if administered by a physician who believes it to be superior to alternative drugs appears to have received little attention. Such preferences exist in medical practice. The present study was undertaken to test the hypothesis that they have a measurable effect, provided the drug is administered knowingly. The efficacy of the drug of choice of three psychiatrists was therefore compared (a) under single blind and double blind conditions, and (b) with that of alternative medication.
