1Department of Psychology, University of Oslo, Norway.
Abstract:
The long-term effect of treatment is defined as the score change produced directly and indirectly by the treatment during and after the treatment interval. Various instances of combinations of short-term effects, attained during the treatment interval, and of long-term effects are presented. Designs for measuring the short-term and long-term effects are sketched, and suggestions are given for distinguishing between these effects in six representative cases. A multiple-occasion measurement of the long-term effect is recommended.
