The Study of Internet-delivered, Transdiagnostic Treatments for Anxiety and Depression (TRAbee)
The Study of Internet-delivered, Transdiagnostic Treatments for Anxiety and Depression ("TRAnsdiagnostisk BEhandling (Elektronisk)")
Anxiety and depression are common psychiatric disorders, resulting in suffering and impaired functioning for the individual. Today, most psychological treatments are disorder specific, even tough comorbidity between depression and anxiety and different anxiety disorders is rule rather than exception. Transdiagnostic treatments target the common features between depression and anxiety disorders and has shown to be as effective as disorder specific treatments in reducing symptoms of the disorders. Unified protocol and Affect phobia treatment are two types of transdiagnostic treatments that, to our knowledge, never been compared in research before. Internet-administered treatment presents a promising way to increase availability of psychotherapeutic interventions such as transdiagnostic treatments. However, questions regarding the optimal treatment length and level of support remain unanswered. The aim of this study is to examine two internet-administered transdiagnostic treatments and their effect on anxiety and depression, and to investigate the impact of treatment length and access to a moderated forum.
The study will investigate three factors: type of transdiagnostic treatment, length of treatment and whether patients have access to a moderated forum or not. 2400 participants with anxiety and/or depression will be randomly assigned to one of 12 subgroups and subsequently offered treatment based on differing combinations of the previously mentioned factors (200 participants/arm). The treatment conditions are internet-administered cognitive, behavioral treatment (CBT) Unified protocol and the psychodynamic Affect phobia treatment as well as a waitlist control group. Participants will also be randomized to either 8 or 16 weeks of treatment and access to a moderated forum or not.
Primary outcome measures will be the Patient Health Questionnaire, the Generalized Anxiety Disorder 7-item scale and the Brief Quality of Life scale. Negative effects of treatment will also be assessed. In addition to pre- and post-treatment measurements, the study includes one mid-treatment and three follow-up assessments (6, 12 and 24 months).

Arms and Interventions

Intervention / Treatment |
---|---|
Experimental: CBT, 8 weeks and access to forum.
|
Treatment condition: The cognitive, behavioral treatment Unified protocol is a transdiagnostic treatment for anxiety and depression. Participants are taught five techniques in order to find new and more helpful ways to react to hindering thoughts and feelings: mindfulness, cognitive flexibility, identify and reduce behavioral avoidance, increase willingness to experience physiological sensations and exposure. The intervention is delivered online through a secure platform. Modules consist of text and the participants can work with the material whenever they wish to. Participants gain access to a new treatment modul every week.
Participants will partake in their treatment condition for 8 weeks.
During their treatment, participants will have access to a discussion forum moderated by a clinician.
Participants are encouraged to discuss questions and experiences related to their treatment condition.
|
Experimental: CBT, 16 weeks and access to forum.

Participants will partake in their treatment condition for 8 weeks.
During their treatment, participants will have access to a discussion forum moderated by a clinician.
Participants are encouraged to discuss questions and experiences related to their treatment condition.
The aim of psychodynamic Affect phobia treatment is for the patient to reach an intellectual and emotional understanding of his/hers problems.
The goal of the treatment is for participants to decrease emotional avoidance and start to approach emotions and increase emotional awareness.
Participants are taught this through linking their symptoms to their emotional avoidance, observe frequent and maladaptive patterns in relationships and see how these are linked to emotional avoidance.
The intervention is delivered online through a secure platform.
