Digital Interventions for Dual Diagnosis

Abstract

Dual diagnosis is a leading contributor of disease burden worldwide. Whilst integrated treatment is recommended, there are considerable barriers that may inhibit access to integrated care, including a lack of training and resources. Digital interventions may enable access to support, providing a space for people to engage in treatment when they need it most. This chapter reviews the current literature on the efficacy of digital interventions for dual diagnosis. Computer-based interventions were effective at improving dual diagnosis outcomes; however, the combined effect of computer-based interventions and therapist support was found to be more effective than the effects of computer-based interventions alone. The evidence-base around smartphone applications is lacking, and there are perceived difficulties with this technology in addressing the complexity of issues faced by people with dual diagnosis. Future research should include standardised terminology to describe techniques used within interventions and consider a variety of research methods to understand implementation.
