An introduction to intensive design in the evaluation of drug efficacy during psychotherapy
The evaluation of psychotropic drugs shares a good many problems with the evaluation of psychotherapy: the problem of valid and reliable judgments, the effect of time, and the problem of understanding and demonstrating the process of the therapeutic effect, rather than a mere evaluation of the result (Bellak, 1961). Not the least among these difficulties derives from the procedure of testing various hypotheses between groups of patients concerning the relative efficacy of two or more medications. The inability to specify particular patient parameters in relation to the statistical results of such studies, the vagueness of the population of patients from which the study patients are presumably considered as a random sample, and the consequent poverty of operational implications of the results of such studies, are among the many difficulties one encounters in what has been called the extensive model of clinical research design.
