Quality assessment of a sample of mobile app-based health behavior change interventions using a tool based on the National Institute of Health and Care Excellence behavior change guidance

Abstract

Quality assessment of health behaviour change apps using a tool developed from NICE guidance 2 AbstractObjective: To quality assess a sample of health behavior change apps from the NHS Apps Library using a rating tool based on the 2014 National Institute for Health and Care Excellence behavior change guidance (NICE BCG).Methods: A qualitative analysis of the NICE BCG identified themes and questions for a quality assessment of health behavior change apps. These were refined by further discussion and piloting, and applied by two independent raters to a sample of NHS Library apps (N=49). Disagreements were resolved following discussions with a third rater.Results: Themes identified were; purpose, planning, usability, tailoring, behavior change technique BCT), maintenance, evaluation, data security and documentation. Overall, purpose of the apps was clear, but evidence for collaboration with users or professionals was lacking. Usability information was poor and tailoring disappointing. Most used recognized BCTs but paid less attention to behavior maintenance than initiation. Information on app evaluation and documentation was sparse.Conclusions: This study furthers the work of the NHS apps library, adapting the NICE (2014) behavior change guidance for quality assessment of behavior change apps.Practice Implications: This study helps lay the foundations for development of a quality assurance tool for mobile health apps aimed at health behavior change.Quality assessment of health behaviour change apps using a tool developed from NICE guidance 3 Quality assessment of a sample of mobile app-based health behavior change interventions using a tool developed using the National Institute of Health and Care Excellence behavior change guidance.

Delivering Cognitive Behavior Therapy to Young Adults With Symptoms of Depression and Anxiety Using a Fully Automated Conversational Agent (Woebot): A Randomized Controlled Trial

“…This underscores the importance of including trained and seasoned clinicians in clinical app design processes. While this point has been suggested, for example in the recent guidelines for clinical app evaluation published by the American Psychiatric Association [31], and in the United Kingdom by the National Institute for Health and Care Excellence [32], this study goes some way towards illustrating the impact that therapeutic process variables may have on user experience in the context of mental health apps.…”

Health‐e mums: Evaluating a smartphone app design for diabetes prevention in women with previous gestational diabetes

“…For the women participating in our focus groups, the Health‐e Mums app was found to be functional and provided an acceptable user experience for women with previous GDM. While a plethora of health‐focused apps exist, few are evidence‐based and even fewer are based on rigorously evaluated behaviour change theory or randomised controlled trial program evidence . Health‐e Mums is novel and differs from the available GDM apps because of its postnatal focus on diabetes prevention and screening, which makes it all the more pressing to evaluate it as a means to addressing a large public health issue.…”

Chinese Mobile Health APPs for Hypertension Management: A Systematic Evaluation of Usefulness

“…At present, the mHealth APP market in China is explosively growing due to the popularization of smartphones [29]; friendly human-phone interactive interfaces [30]; the convenient, prompt, and barrier-free access of mobile phones [31]; and the bonus of living habits brought by mobile-end E-commerce [32]. Although APP developers can use different sensors carried by mobile facilities, the commonly used device is only the cam; namely, P2 was supported by approximately 58% of APPs (42).…”
