Investigating defense interpretation depth using lag sequential analysis

Abstract

Aim of the studyThis study investigated the association between therapist interventions and patient defensive functioning in low-alliance and high-alliance sessions over the course of short-term dynamic psychotherapy (STDP) (n= 22).Subject or material and methodsLag sequential analysis was used to determine if there were predictable sequences of therapist interventions and patient defenses in low-alliance and high alliance sessions and whether these two sequences differ.ResultsThe results of this study suggest that sequences between alliance session groups are different. Specifically, defense interpretation depth unfolds in a predictable fashion during a low-alliance session while supportive strategies appear more predictable during high-alliance sessions.DiscussionThe statistical trends obtained in this study are discussed in light of prior research studies in this area. Specifically, differences between low and high alliance sessions are discussed.ConclusionsDefense interpretation depth is a clinical construct that warrants further study in psychotherapy research.
