Detailed Description
This study will use a digital tool with the aim to test whether a "Virtual Coach" can increase treatment adaptation (i.e., learning of therapy skills, prevent drop-out), treatment utility (i.e., via direct feedback to the patient and therapist), and increase adherence. The digital tool will be an avatar-led application for smartphones and be based on the Acceptance and Commitment Therapy.
The "Virtual Coach" will be used adjunctive to therapy and help patients initiate behavioral changes and accelerate the learning of new therapy skills. The questions addressed will be the following: a) adherence to and utilization of the Virtual Coach itself ; b) application of therapy skills; c) perceived usefulness of the Virtual Coach by patients and therapists, and d) the frequency of prosocial behaviors and their impact on well-being.
The main purpose of this study is the feasibility of using the Virtual Coach adjunctively to a therapy. However, it also will be explored how outcomes may be related to the severity of symptoms and other factors.
The study contains a pilot test in a single-arm trial to evaluate the main outcomes of acceptability (adherence, utilization, utility, satisfaction) with n = 40. Patients will be assessed at baseline and again after the course of their psychotherapy (post-assessment).
Patients will complete informed consent, undergo a short diagnostic assessment, then receive a smartphone with the application to carry for one week. They will be asked to use the application at least three times per day in order to practice skills involved in the treatment. The assessment targets will include intentions, activities, and goals of the patient, interpersonal activities, and health behaviors. Subjective reports (e.g., emotions, thoughts, reactions, plans) and objective data (response times, adherence to prompts, etc.) will be tracked. In addition to the main acceptability outcomes, additional assessments will be used to measure patient characteristics. This will include a diagnostic interview, questionnaires about symptomatology, well-being, social interactions, and an exit questionnaire when leaving the study to assess what was learned.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Study Group
Participants receive the Virtual Coach App for one week at the beginning of their therapy and one week towards the end of their therapy.
|
The avatar-guided app aims to deepen the user's understanding of Acceptance and Commitment Therapy (ACT) and promote application of ACT skills in every-day-life.
Event-Sampling-Methodology (ESM) is used to capture the user's progress as it unfolds.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
User Experience Questionnaire
Time Frame: once at Baseline (beginning of therapy/week 1)
|
User Experience Questionnaire (UEQ; Laugwitz, B., Schrepp, M. & Held, T., 2008).
The UEQ is a short questionnaire using semantic differentials (word pairs with opposite meanings) to allow for fast and intuitive responses.
An example item would be "attractive - unattractive".
Items are scored on a 7-point Likert scale and range from full agreement with the negative term (-3) to the full agreement with the positive term (+3).
Half of the items start with the positive term, the rest with the negative term.
Higher sum scores indicate more positive evaluation of the app.
|
once at Baseline (beginning of therapy/week 1)
|
System Usability Scale
Time Frame: up to 3 months (from Baseline/beginning of treatment to Post/end of treatment)
|
System Usability Scale (SUS; adapted from Brooke, 1996) embedded.
SUS scores have a range of 0 to 100.
A high score indicates a high system usability; and where 1 = strongly disagree and 5 = strongly agree.
|
up to 3 months (from Baseline/beginning of treatment to Post/end of treatment)
|
Semi-structured User Experience Questionnaire
Time Frame: up to 3 months (from Baseline/beginning of treatment to Post/end of treatment)
|
Self-designed questionnaire with closed and open questions regarding the user's experience with the app.
Questions were tested in a pilot and then adapted in a feedback round.
They include items such as "How was your week with Virtual Coach?", "What about Virtual Coach did you like best?", "What about Virtual Coach did you like least?", etc.
The Interview also includes space for open comments from the user.
|
up to 3 months (from Baseline/beginning of treatment to Post/end of treatment)
|
User Adherence Meta-Variables
Time Frame: up to 3 months (from Baseline/beginning of treatment to Post/end of treatment)
|
Metavariables and app-usage of participants are collected automatically while the app is being used by the study participant, such as:
|
up to 3 months (from Baseline/beginning of treatment to Post/end of treatment)

Time Frame |
---|---|---|

These items are rated on 9- point scales ranging from 1 (Not at all logical/useful/confident) to 9 (Very logical/useful/confident), with a total score possible range of 3 to 27.
The last three items form the expectancy factor: one item is assessed on the same 9-point scale as the credibility items and two are assessed on an 11-point scale (from 0% to 100% in 10-point increments), responses are first standardized before summing to render the expectancy total score.
A higher score symbolizes a high expectancy of the patient in the the treatment.
