Brief Summary:
The primary goal of this randomized controlled trial is to compare the effectiveness of two transdiagnostic psychological treatments, Metacognitive Therapy (MCT) and the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP), for patients with complex anxiety.
Detailed Description:
Background:
Anxiety disorders are highly prevalent, impairing quality of life and contributing to substantial economic burden. A large portion of the affected individuals also fulfill the criteria for at least one other anxiety disorder and/or depression. This comorbidity is associated with increased symptom severity and a poorer prognosis. Cognitive-behavioral therapy (CBT) is effective but traditionally relies on a specific manual for every distinct disorder, complicating the management of comorbidity and increasing training needs for therapists. Transdiagnostic therapies target underlying, shared mechanisms across anxiety disorders and depression, and can be used regardless of specific diagnoses. They thereby offer potential for efficient treatment of complex presentations, addressing a wider range of patients' problems with simplified therapist training.
Aims:
The primary aim of the study is to compare the effectiveness of two transdiagnostic therapies, MCT and UP, for patients with comorbid anxiety. Beyond evaluating effectiveness, the project seeks to identify the key factors that drive improvement during treatment. Research questions:
1. Are there differences in effect between MCT and UP regarding clinician-rated severity of anxiety and depression diagnoses after treatment?
2. Are there differences in effect between MCT and UP regarding patients' self-reported symptoms of anxiety, depression, and functioning after treatment?
3. Are there differences in effect between MCT and UP regarding clinician-rated severity of anxiety and depression diagnoses, as well as patients' self-reported symptoms of anxiety, depression, and functioning, at the 1-year follow-up after completed treatment?
4. Does improvement occur in patients in the way that the treatment methods (MCT and UP, respectively) are intended to work, according to the presumptive mechanisms of change?
Methods:
* Design and participants: Patients (N = 114) are randomly allocated in a 1:1 ratio to MCT or UP. Patients are consecutively recruited from the regular influx at two psychiatric clinicis in Stockholm, Sweden. See sections Study design and Eligibility.
* Measurements: Most measures are rated at baseline, post-treatment and at the 1-year follow-up. For the purpose of mediational analyses, procsess measures as well as outcome measures of anxiety and depression are rated weekly during treatment. See section Outcome Measures.
* Treatment conditions: Treatment (MCT or UP) is delivered in approximately 10-18 weekly face-to-face sessions. See section Arms and Interventions.
* Data analyses: Analyses of treatment effects, including the primary outcome of pre- to post changes in Clinical Severity Rating (CSR) between conditions, are conducted according to the intention-to treat principle, using multilevel modeling. Model-based effect sizes, with 95% confidence intervals, are also calculated. For assessment of treatment response, disorder-specific measures are used with criteria for reliable change and clinical cut-off, rendering the categories recovered, improved, unchanged, or deteriorated. Remission status is also assessed according to blinded clinician-rated severity of anxiety and depression diagnoses after treatment, where CSR \< 4 means that a patient no longer fulfills criteria for a diagnosis. Differences in proportions are evaluated with chi-squared tests. Mediational analyses are conducted by disaggregating potential mediators to their within- and between-person components. To establish a temporal sequence between mediator and outcome, mediator scores are lagged relative to outcome.
