Design outcomes

Primary

MeasureTime frame
The acceptability of the CaTS-App© in achieving its core objectives (improved communication, understanding, decision-making) measured using an 18-item survey of open and closed responses at endpoint

Secondary

MeasureTime frame
1. Symptoms of depression and anxiety measured using the Revised Child Anxiety and Depression Scale (RCADS) at baseline and endpoint 2. Frequency of self-harm/thoughts in the last week measured through a Pre-Clinical Impact Survey (Pre-CIS) at baseline 3. Participant engagement with the CaTS-App© measured through metrics collected by the app at the end of the study 4. Current emotional state measured using a Wellbeing Check through a visual analogue scale (VAS) at the start and end of each session using the app 5. Initial thoughts and feedback collected through Reflection Logs on completion of each step of the CaTS-App© 6. Frequency of self-harm/thoughts in the last week, and impact of the CaTS-App© on self-harm and suicidal thoughts measured through a Post-Clinical Impact Survey (Post-CIS) at endpoint 7. The usability of CaTS-App© measured through a 10-item Likert questionnaire, the System Usability Scale (SUS) adapted for CaTS-App©, at endpoint 8. Experiences of using the CaTS-App© collected using an online interview at endpoint
