Therapeutic techniques and session impact: A practice-research network study in private practice.

Objective: This study investigated the relationship between therapeutic techniques and session impact, by examining the replicability of findings observed in a university-based training clinic (Boswell et al., 2010) in another practice-oriented setting: private practice.

Method: N = 8 therapists completed session-level assessments of their technique use for N = 38 clients. The same client sample completed session-level assessments of session outcome. Technique-outcome associations were examined with multilevel models.

Results: As in Boswell et al., common factors were associated with positive session impact. For clients who received higher average common factor techniques (relative to their own therapist's caseload), session impact was the poorest in sessions with higher behavioral change techniques use (relative to the client's own average). Moreover, clients with the lowest average common factor techniques (relative to their therapist's caseload) reported better session impact in sessions that involved a higher degree of session-level behavioral change techniques (relative to their own average).

Conclusion: In line with Boswell et al., therapists should be mindful of the consistency of their routine technique use between- and within-clients, and this can be aided through collection of their own practice-oriented data.
