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.
