Interpretive work in short-term individual psychotherapy: an analysis using hierarchical linear modeling.

"Work" and "resistance" responses to interpretation in short-term individual (STI) psychotherapy were examined using a hierarchical linear modeling (HLM) procedure. The relationships between interpretation characteristics and patient responses within therapy were considered. Process data were drawn from 60 STI therapy cases, 30 patients with low quality of object relations (QOR), and 30 patients with high QOR. In 4 instances, the relationships between technique and response were found to vary significantly across cases. One was identified for low QOR patients, and 3 were identified for high QOR patients. Individual differences in initial disturbance and outcome were used to account for the variation of technique-response relationships. Significant findings were limited to the high QOR sample. Initial disturbance was directly related to work in response to a transference-oriented approach. The transference focus-work relationship was found to be inversely related to outcome. The results extend previous findings regarding transference technique in STI therapy with high QOR patients. Through capitalizing on within-case variation, HLM can be used to illuminate process-outcome relationships in psychotherapy.
