This research investigates how and to what extent Persuasive Systems Design (PSD) in Behavior Change Support Systems (BCSS) influences recovery from digital and alcohol addiction. Although digital health interventions have shown promising results in behavioral change, there is still a gap in understanding how specific persuasive software features affect addiction treatment outcomes. Therefore, this research aims to expand our understanding of effective design elements and software features for addiction recovery. Interactions of persuasive software features with well-being, self-efficacy, addiction behavior change and user engagement outputs will be assessed in three stages. Stage 1 will lay the foundation of the application design, then in Stage 2 the application will be designed and developed, and a pilot study will be conducted. Following Stage 1 and Stage 2, two experimental research are planned to test the developed BCSS's effectiveness in Stage 3. The findings of the research will provide clear views on how a BCSS can be better designed and applied to real-world settings specifically for addictions.
