Summary

The Kiso pilot study is a randomized controlled trial to test the acceptability and feasibility of a novel digital intervention, namely the Kiso Mind smartphone app. A parallel-group design is utilized. Participants either receive access to the Kiso Mind intervention and treatment-as-usual (TAU) in the experimental condition or receive treatment as usual (TAU) in the control condition. The intervention is designed for participants diagnosed with either schizophrenia (F20.0) or schizoaffective disorder (F25.0) according to the ICD-10. To examine acceptability, feasibility, and preliminary effectiveness, both self-report and rater-based assessments are administered at baseline (T0) and at the end of the 12-week intervention period (post-intervention T1). Lastly, a qualitative interview will be conducted with participants from the experimental condition. The primary outcome of the present study is the acceptability and feasibility of the Kiso Mind app. The secondary outcome consists of general psychopathology, and positive-, negative-, depressive symptoms, as well as social functioning and self-efficacy ratings.

Detailed description

There are multiple ways to join the present study. Healthcare workers at different institutions across Germany identify eligible participants and invite them to participate in the study. Those institutions include inpatient wards and outpatient facilities. Moreover, participants can join via multiple channels, including online channels and advertising such as social media, etc. Eligibility screenings and baseline clinician ratings are conducted centrally by research associates (psychologists) at Charité Universitätsmedizin Berlin via a video interview. After confirming the inclusion criteria, participants will be randomised and receive the self-report section of the baseline assessment. Randomization is conducted independently by research associates at the Universitätsklinikum Hamburg-Eppendorf in Hamburg. After 12 weeks, participants complete a clinical interview to assess the rater-based section of the post-treatment assessment and receive the self-report section via email. All participant data is stored in a pseudonymized format. No clinical data is saved in combination with clinical data. The participants have the right to access their data and the right to claim deletion of their data. Data are stored in an online database, accessible only to researchers involved in the study. Due to the exploratory nature of this study, we aim to recruit 60 to 80 participants in total until June.
