Twenty-two junior, senior, and graduate students from an introductory counseling class for nonmajors were introduced to the verbal psychotherapies, and randomly divided into treatment and control groups. The groups were treated identically and received the usual instructional program except for the treatment group receiving 30 minutes of instruction in an algorithm for making interpretations. The instruction was presented as a curricular package introduced by written material describing three types of interpretations identified by Levy: (1) reclassifications--placing some client event within a broader class of events (i.e. labeling or naming); (2) connections--connecting aspects of the client's behaviors or experiences in ways not recognized by the client; and (3) explanations--introducing a more abstract idea to account for behavior or connections. The algorithm outlined a process for identifying conditions appropriate to making an interpretation, for formulating an interpretation according to one of the three types, and for following up on that interpretation. In role-played interviews, the treatment group made more than the expected number of moderate and deep interpretations; the control group made fewer. (Author/RL)
