Towards a Non-Functional Requirements Discovery Approach for Persuasive Systems

[Abstract] A number of software systems that attempt to help people achieve behavior change have been proposed in various domains such as health and wellness. However, sometimes, such systems have failed to provide a satisfactory or sustainable User Experience (UX), as it is observed when users may be reluctant to respond to the activation of the systems' changing demands. Moreover, a negative User Experience (UX) can be exposed by Behavior Change Support Systems (BCSS) if designers do not have clear understanding of the requirements that factually help changing the user behavior that accomplishes a sustainability goal. We first explored the Persuasive System Design (PSD) model that should be considered in UX assessment of BCSSs. Then, we propose a requirements discovery process that can be considered to redesign a software interactive system based on negative UX.This work has received partial support by the projects FEDER-UE CSI ED431G/01, ED43C 2018/29, accreditation 2016-2019 ED431G/08, KUSISQA supported by N° 014-2019-FONDECYT-BM-INC.INV, NOVA LINCS UID/CEC/04516/2019, MICINN IJC2018-037522-I, RTI2018-099646-B-I00Xunta de Galicia; ED431G/01Xunta de Galicia; ED43C 2018/29Xunta de Galicia; ED431G/08Gobierno de Chile; 014-2019-FONDECYTBM-INC.INVRepública Portuguesa.

Literature-based requirements analysis review of persuasive systems design for mental health applications

Mental health problems are becoming more common while access to treatment is often not available to everyone who needs help. Recent advances in information technology, the wide availability of the internet, the emergence of smartphones and their common usage worldwide raise hope for more treatment options for mental health disorders. Many mobile phone apps that claim to assist in treating a variety of mental health disorders are already available, and the number of such apps continues to increase. The availability of such apps raises many questions about their effectiveness, suitable treatment methods, possibilities for use alongside traditional treatment methods, possible risks and other uncertainties. Beside mobile apps, internet-based apps are also being introduced with similar sets of challenges and ambiguities. One area of research that is gaining a lot of attention recently is Persuasive System Design and Behavior Change. Persuasive System Design is considered one solution that has the potential to help solve the challenges of lack of user motivation and adherence when utilizing mental health applications. The goal of this paper is to perform a literature review, in order to determine the most essential requirements for a persuasively designed mental health application. As part of this process, the challenges and requests of the end-user will be taken into account in order to make recommendations for the future design of such applications
