Mobile phone apps are increasingly popular in usage especially in the health sector. Apps such as mHealth have been used internationally to address many concerns in particular those brought by non-communicable diseases such as diabetes. However, there seem to be a growing interest for mental health apps as a solution in reducing the barriers surrounding services uptake. Apps are seen to bridge the gap between self-care and the augmentation of the existing clinical treatment processes. With more research pertaining to mental health apps, there has been a recognizable knowledge of the importance of delivering effective treatment modalities within the app. Reviews of contemporary literatures supported the need for a scoping review as there is a lack of high-quality research such as randomized control trials done in determining the best current practice to provide interventions within a mental health app. This scoping review Aims to ascertain the interventional domains that are most appropriate to supplement the screening tool in the current 2Heal mental health app. The scoping review will be done according to the Arksey and O’Malley (2005) methodological approach as a guiding framework. The steps involved will be identifying the research question, identifying the relevant studies, describing the study selection, charting the data and lastly, reporting the results. This scoping review will be reported according to the PRISMA Extension for Scoping Reviews. The summary and results of this study are expected to contribute to the future development of interventional content or mental health app that are evidence-based, reliable and suitable to the current best practice pertaining to mental health problems.
