Patient-driven Internet Delivered Psychological Treatment

Study Overview
=================
Brief Summary
-----------------
The effect of iCBT for adults with anxiety disorders is well-known. However, drop-out rates are common. In recent years more focus has been directed to the importance of patients being active agents in their own care and to increase the patient´s involvement in health care. Studies show that involving patients´ in treatment decisions and management of their own health care can contribute to better treatment outcomes and more appropriate use of health care service. Few studies have evaluated patient involvement in iCBT-treatment. This study aims to evaluate the effect of patient-driven iCBT-treatment for patients with anxiety disorders seeking primary care in a randomized controlled trial. The study investigates the effect of patient-driven iCBT treatment of perceptions of being able to control the treatment and on drop-out from treatment. In addition, secondary research questions investigate measures of empowerment, anxiety and depression symptoms, general disability, satisfaction with treatment and feelings of being able to cope with one's mental illness in patient-driven iCBT.

Detailed Description
-----------------
The following research questions will be examined: Primary research questions: Is there a difference between participants in patient-driven digital psychological treatment, compared to standardized internet CBT, in perceptions of how much they've been able to control their treatment (measured with a questionnaire developed by the researchers for this study)? What is the effect of patient-driven digital psychological treatment, compared to standardized internet CBT, on frequency of completers and completed modules among adults with anxiety disorders? Secondary research questions: What is the effect of patient-driven digital psychological treatment, compared to standardized internet CBT, on the experience of empowerment, (measured by the Empowerment Scale), for adults with anxiety disorders? What is the effect of patient-driven digital psychological treatment, compared to standardized internet CBT, on anxiety (measured with GAD-7), depression (measured with MADRS-S), general disability (measured with WHODAS 2.0) and steps in valued direction (measured with Bull´s Eye compass) for adults with anxiety disorders? Associations: Is there a correlation between perceptions of how much one has been able to control the treatment (measured with a questionnaire developed by the researchers for this study), feelings of being able to cope with one's mental illness (measured with Patient Enablement Instrument), how satisfied participants are with their treatment (measured vid CSQ-8), perceptions of empowerment (measured with the Empowerment Scale) and changes in anxiety symptoms (measured with GAD-7)? Does perceptions of how much participants have been affected by the pandemic of Covid-19 in their daily life correlate with anxiety symptoms (measured with GAD-7) 3 months after termination of treatment? Mediation: What is the mediating effect of empowerment, measured by the Empowerment Scale, on changes in anxiety symptoms (measured with GAD-7)?

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Patient-driven iCBT<br>Participants who are randomized to the experimental condition are asked to make choices regarding the structure of their treatment program | Behavioral: Patient-driven iCBT<br>* 1) Participants who are randomized to the experimental condition are asked to make choices regarding the structure of their treatment by the time of the randomization call. The participant can choose which of the available treatment programs (targeting anxiety, worry, stress, sleep disorders or depression) they want to undergo, how many modules in the treatment program they want to complete and in what order, for how many weeks they want to complete the treatment as well as how much telephone contact and how much written contact they want to have with their therapist.<br>|
| Active Comparator: Standardized iCBT (TAU)<br>Patients who are randomized to the control condition undergo the usual iCBT program available for anxiety disorders for a standardized time period of 8 weeks | Behavioral: Standardized iCBT (TAU)<br>* 2) Patients who are randomized to the control condition (standardized iCBT) undergo the usual iCBT program available for anxiety disorders for 8 weeks. The psychologist provide weekly feedback on the patient's exercises and interact with the patient via secure encrypted messages in the treatment program. A follow-up telephone call takes place at the middle of treatment and at the end of the treatment.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Questions of perceptions in how much one has been able to control the treatment | Perceptions in how much one has been able to control the treatment is measured by a questionnaire developed by the researchers for this study. The questionnaire consists of 9 items and each item is answered on a seven-point scale, from Not at all to To a large extent. | At the end of treatment (after 8-16 weeks depending on treatment condition) | 
| Adherence to treatment | Adherence to treatment is measured by counting number of completed modules in the treatment program for each participant | At the end of treatment (after 8-16 weeks depending on treatment condition) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Changes in feelings of empowerment | Empowerment is measured with the Empowerment Scale (Rogers, Chamberlin, Ellison & Crean, 1997). The scale consists of 28 items which are answered on a four-point likert scale. Score ranges between 28 and 112.

| Perceptions of being able to cope with one's mental illness | Perceptions of being able to cope with one's mental illness is measured with the Patient Enablement Instrument (PEI; Howie, Heaney & Maxwell, 1997).
