Abstract:Background: In response to the “mental health treatment gap”, which concerns the lack of access to mental healthcare services, new technologies are evolving. In studies investigating the effectiveness of a type of mobile mental health intervention known as ecological momentary interventions (EMIs), there exists a research gap regarding proximal mental health outcomes, their effectiveness and for whom they work. This study investigated EMIs’ proximal effects on mental distress and with anxiety being one of the most prevalent disorders, addressed anxiety as a potential moderator. Methods: In this micro-randomized trial (MRT), participants (N=72) were randomly assigned to either receive an EMI – PPI or CBT exercise – or not four times each day for 16 days. Participants’ anxiety scores were measured before and after the intervention phase. Before and 30 minutes after the EMI participants received the same EMA questionnaires, that measured mental distress so that the exercises’ proximal effect could be investigated. The statistical analysis utilized Linear Mixed Effects Models for the analyses. Results: Neither the PPI exercise (p = .157) nor the CBT exercise (p = .812) were effective in significantly decreasing mental distress and anxiety did not moderate their effects on mental distress.
