Abstract:
The therapeutic alliance is often regarded as the quintessential common factor. However, methodological limitations of research to date make it unclear whether alliance truly operates in a uniform manner across time in disparate psychotherapy treatment approaches. This study examines the course of alliance across two manualized treatments, Cognitive-Behavioral Therapy (CBT) and Interpersonal/Emotional Processing Therapy (IEP) for Generalized Anxiety Disorder, administered concurrently to the same clients by the same therapists in an additive design. Findings suggest that therapist-rated alliance was slightly higher in CBT than IEP and increased linearly over time for both treatment approaches. Client-rated alliance failed to show a treatment type, phase, or type-by-phase interaction. Results are discussed in terms of common factors theory, research on temporal patterns of alliance, and treatment-specific effects. Limitations and future directions are also discussed.
