RT Article T1 Understanding Engagement With Forensic Smartphone Apps: The Service Design Engagement Model JF International journal of offender therapy and comparative criminology VO 68 IS 10/11 SP 1106 OP 1123 A1 Ross, Stuart A2 Wood, Mark A. A2 Johns, Diana A2 Murphy, John A2 Baird, Ron A2 Alford, Brooke LA English YR 2024 UL https://krimdok.uni-tuebingen.de/Record/1895165717 AB Justice services have begun to integrate the use of mobile applications into treatment, support, and rehabilitative programs for forensic clients. One such application that been adopted to support forensic clients is “eRecovery”: a smartphone application that provides clients recovering from a substance addiction with support for managing relapse. In this article, we report on evaluation findings from a trial of eRecovery in an Australian Community Justice Centre, and reflect on several issues relating to fostering and sustaining client engagement with similar applications within forensic and justice settings. We propose the Service Design Engagement Model to organize, visualize, and describe the stages and factors important to adoption, appropriation, and on-going routine use of the software by forensic clients. The model recognizes the role of contextual and environmental factors in supporting users through the early stages of engagement, and the importance of user agency in longer-term engagement with therapeutic apps.
