ABSTRACT

Background:

In collaboration with clinical domain experts, we have developed a prototype of immersive VR cognitive remediation for major depressive disorder, bWell-D. In the development of a new digital intervention, there is a need to determine the effective components and clinical relevance using systematic methodologies. From an implementation perspective, the effectiveness of digital intervention delivery is challenged by low uptake and high non-compliance rates. Gamification may play a role in addressing this since it can boost adherence. However, careful consideration is required in its application in order to promote user motivation intrinsically.

Objective:

We aimed to address these challenges with an iterative process for development that involves co-design for developing content as well as in the application of gamification, while also taking into consideration behavioural change theories. This effort followed the methodological framework guidelines outlined by an international working group for development of VR therapies.

Methods:

Following best practice guidelines, we collected qualitative data from patients and care providers to understand end-user perceptions on the use of VR technologies for cognitive remediation, reveal insights on the drivers for behavioural change, and obtain suggestions for changes specific to the VR program. These findings were translated into concrete representative software functionalities/features and evaluated against behavioural theories to characterize gamification elements in terms of factors that drive behavioural change and intrinsic engagement.

Results:

The results indicated that feedback from end-users centred around using gamification to add artificial challenges, personalization/customization options and artificial assistance while focusing on Capability as the behavioural change driver. It was also found that in terms of promoting intrinsic engagement, the need to meet Competence was most frequently raised. Feedback was obtained from users to evaluate the impact of the implemented changes. It was found that bWell-D was well tolerated, and that the improvements led to an increase in user experience ratings with high engagement reported throughout the duration of an 8-week training program.

Conclusions:

Here, we present a process for the application of gamification that includes characterizing what was applied in a standardized way and identifying the underlying mechanisms that are targeted. Typical gamification elements, such as points/scoring and rewards/prizes, target Motivation in an extrinsic fashion. In this work, it was found that modifications suggested from end users resulted in the inclusion of gamification elements less commonly observed and tended to focus more on individual ability. It was found that the incorporation of end-user feedback can lead to the application of gamification in broader ways with the identification of elements that are potentially better suited for mental health domains.
