The working alliance predicts session-by-session change in problems and functioning in short-term psychodynamic...

Area of Science:

• Psychology
• Psychotherapy Research
• Clinical Psychology

Background:

• The working alliance is theorized as a key mechanism for change in psychodynamic therapy.
• Empirical investigation into the session-by-session impact of the working alliance on therapeutic outcomes in this modality is limited.
• Understanding alliance-outcome dynamics is crucial for optimizing short-term psychodynamic psychotherapy.

Purpose of the Study:

• To examine the session-by-session influence of client- and therapist-reported working alliance on subsequent session problems/functioning in short-term psychodynamic therapy.
• To investigate whether baseline personality functioning and adverse childhood experiences moderate the alliance-outcome relationship.

Main Methods:

• 152 clients undergoing short-term psychodynamic psychotherapy with novice therapists participated.
• Client-reported outcome (Clinical Outcomes in Routine Evaluation-10) and alliance (Working Alliance Inventory-Short) were assessed pre- and post-session, respectively.
• Continuous time structural equation modeling was employed to analyze the data, allowing for causal inferences.

Main Results:

• Client-reported alliance improvement significantly predicted reduced next-session problems/dysfunction, with a small effect size that grew to large after 7-8 sessions.
• Client problems/functioning also significantly impacted the client-reported alliance.
• Therapist-reported alliance did not predict outcome; however, the client-alliance effect was stronger for clients with more adverse childhood experiences.

Conclusions:

• The client-reported working alliance is a significant predictor of subsequent therapeutic outcomes in short-term psychodynamic therapy.
• The alliance's impact on outcome appears cumulative, peaking around 7-8 sessions, aligning with psychodynamic principles.
• Individual differences, such as adverse childhood experiences, can influence the strength of the client-alliance-outcome link.
