A Digital Mental Health Intervention for Children and Parents Using a User-Centred Design

Table 1

Visualization of the design solutions related to the assumptions made.

Main functionalities	Key assumption and secondary assumptions
Showing daily and weekly emotion changes using emotion detection	It is successfully testing the key assumption as the parents can monitor the emotion change of their children and detect any red flags that may arise.
Screen-based avatar and smart speaker	Secondary assumptions 2, 3, and 4 are tested by this feature. The successful testing of this functionality shows that including a screen that displays the avatar picked by the children creates a long-term relationship between children and the product in a friendly way.
Calendar	The calendar feature successfully tests the secondary assumption 5 because the analysis of the children’s emotions is displayed in an organised and structured way through the calendar for parents' control.
Reminders	Including a reminder functionality successfully tests secondary assumption 6 as it alerts parents of any problems with their children, and, if necessary, devotes time to their children, maintaining work and family responsibilities.
Having a scheduled messaging platform	Secondary assumption 7 is tested by including a message feature, as the platform helps parents send any text or voicemail to their kids at the time and date they set.
Ability to get professional help	Secondary assumption 8 is tested by this feature. The successful testing of this functionality shows that parents do not feel alone when facing their child's mental health problems and helps them get support when needed.
