Abstract
Objectives
We examined patterns in alliance development in cognitive behavioral therapy (CBT) for social anxiety disorder (SAD) compared to attention bias modification (ABM). We focused on the occurrence of sawtooth patterns (increases within- and decreases between-sessions) and sudden gains and their association with outcome.
Methods
Clients received CBT (n = 33) or ABM (n = 17). Client-rated alliance was measured before and after each session. Self-reported and clinician-rated anxiety were measured weekly and monthly, respectively.
Results
The alliance increased in CBT in a sawtooth pattern and did not change in ABM. When examining individual clients, sawtooths were more common in CBT (61% clients) than in ABM (6%) and predicted worse outcome in CBT. Sudden gains were equally frequent (CBT, 18%; ABM, 18%) and did not predict outcome.
Conclusion
The alliance in CBT is dynamic and important for outcome. Sawtooths are common in CBT and may mark worse outcome.
