PEACH: Personality Detection and Digital Personality Coaching
Research has shown that personality traits are changeable over longer time periods, and that changes may bring about positive life outcomes such as greater success in work and family, better health, and longevity. Research also found that most people want to change or modify some aspects of their personality. However, less is known about the short-term changeability of personality traits.
The main aim of the planned research program is to test the efficacy of a smartphone-based intervention for intentional personality change using a novel open source platform that supports the design of evidence-based, scalable and low-cost interventions (www.mobile-coach.eu; Filler et al. 2015; Kowatsch et al. 2017). The research strategy is threefold: (1) to develop a smartphone-based intervention to change personality traits, (2) to examine its efficacy to change personality traits in the desired direction, and (3) to examine underlying processes and mechanisms in an effort to improve the intervention outcomes.
This proposed research is the first testing the efficacy of a smartphone-based intervention for intended personality change. Given that this novel intervention approach proves effective, it could be easily implemented in various non-clinical settings and could reach large numbers of people due to its low-threshold character and technical scalability. The project is innovative from a personality psychology point of view as it examines the short-term changeability of personality traits, from a psychological intervention perspective as it applies a new generic intervention model, and from an information systems perspective as it investigates how mobile sensor services and anthropomorphic conversational agents must be designed to effectively deliver individualized interventions in real life and real time.

The PEACH App and its components are shown in the following figure. Note: Chat-based interaction with the conversational agent PEACH (left), the sidebar (middle) that allows participants to switch to either a dashboard with a personalized overview of the current status of the intervention (right), a media library used for psychoeducational video clips, a chat channel that allows participants to communicate with the “Support-Team”, or a page for frequently asked questions about the PEACH study and the app.
