- Scientific TitleTreatment effects and cost-effectiveness of Autonomy-Enhancing Treatment: A person-centered approach to anxiety disorders
- ACRONYM
- hypothesisAutonomy Enhancing Treatment (AET) is superior to Cognitive Behaviour Therapy (CBT) with regard to person-centred and comorbid outcomes (general psychopathology, depressive symptoms, autonomy-connectedness, self-esteem, quality of life
), and cost-effectiveness.

- InterventionsAutonomy Enhancing Treatment and Cognitive Behaviour Therapy
- Primary outcomePerson-centered outcomes and comorbid symptoms: autonomy-connectedness, general psychopathology, depressive symptoms, self-esteem, quality of life.
Anxiety symptoms will also be assessed.
- Secondary outcomeWe will also estimate cost-effectiveness in terms of quality adjusted life years (QALYs) and direct and indirect costs associated with health care use and work absence/productivity loss.
- TimepointsMeasurements of disorder-specific (anxiety symptoms) and person-centered outcomes (general psychopathology and comorbid depressive symptoms, autonomy-connectedness, self-esteem and quality of life) will take place at 4 moments: before treatment (T1), mid- treatment (T2), after treatment (T3), and at 3 months follow-up (T4). Additional qualitative questions will be asked at T1, T2, and T3. The first groups of patients will be also asked to complete measurements at 6 months (T5) and 12 months (T6) follow-up.
Outcomes related to costs (costs per QALY) will be assessed at T1, T3 and T4 (and T5 and T6 for the first groups), so that costs can be evaluated approximately every three months.

- Brief summaryRationale: Given the symptom-focused nature of Cognitive Behaviour Therapy (CBT) and its inability to deal effectively with comorbidity, there is a clear need for more person-centered anxiety treatments. Autonomy-Enhancing Treatment (AET) is such a person-centered treatment. Group AET will be compared to group CBT. We expect AET to be superior to CBT with respect to person-centered outcomes and comorbid symptoms, providing a more robust therapeutic change. This makes AET also a likely more cost-effective alternative to CBT.
Objective: (1) to compare group AET to group CBT in order to assess their effectiveness on symptoms, person-centered outcomes and comorbid symptoms, and (2) to relate the effectiveness of group AET and group CBT to direct and indirect costs, thereby establishing their cost-effectiveness.
Study design: Multicenter randomized controlled study.
