With the increase in demand for mental health services globally, the need for technology-based interventions (e.g., mobile applications, self-help websites) has risen. Evidence suggests that guided online interventions can be as effective as in-person interventions, along with greater accessibility for populations that may otherwise struggle to receive evidence-based mental health care (e.g., lower income, rural populations). This article provides a detailed overview of and rationale for technology-based methods of psychological intervention, specifically acceptance and commitment therapy (ACT). The effectiveness of technology-based ACT interventions, with and without support, is reviewed. Suggestions for how to implement ACT over technology is discussed, along with challenges and future directions. Additionally, the wide evidence base, both outcome and process research, for technological implementations of ACT is reviewed across disorders and populations. Although the development of technology based ACT interventions is still modest among some populations, the current evidence suggests that they are effective across various mental health concerns and are improving psychological flexibility and well-being.
