Development of scales to measure treatment attitudes in psychiatry.

We used multiple regression analysis to modify and shorten two scales for measuring practitioners' attitudes to psychotherapy and drug therapy. The resulting scales have been combined in a 21-item questionnaire (Treatment Attitudes in Psychiatry Scales (TAPS] which is brief and easy to use, and should have wide application in psychiatry. The results of a concurrent validation of the scales, using two large groups of consultant psychiatrists who were members of either the Biological Psychiatry or Psychotherapy Section of the Royal College of Psychiatrists, show the extent to which their attitudes to psychotherapy or drug therapy tend to overlap. Polarisation of attitudes was more evident in the results from the Biological Psychiatry Section. A method is described by which scores obtained with the TAPS can readily be compared with those obtained by the criterion groups.
