| Abstract: | Mobile mental health interventions show promise in reducing barriers to mental healthcare, with micro-randomised trials (MRTs) increasingly used to support their development by evaluating intervention component effects in real-time. This scoping review examines MRTs on mobile mental health interventions, highlighting common practices and emerging developments to inform future research. A systematic search was conducted across Web of Science, PsycINFO, PubMed, and ClinicalTrial.gov. Data on study and sample characteristics, MRT design choices, and study outcomes were extracted and summarised. The literature search identified 13 studies targeting diverse populations and mental health outcomes. Most studies randomised interventions at daily decision points using equal probabilities, with observations of context collected for exploratory moderation analyses. Some studies additionally used observations of context to personalise intervention content, assess participant availability for randomisation, or align intervention options with individual needs. Study outcomes showed immediate intervention effects that varied depending on contextual factors. Concludingly, MRTs have been applied to a range of early-stage mobile mental health interventions, primarily for exploratory purposes to map out effective intervention strategies. The adoption of more contextually adaptive MRT designs marks progress toward more precise intervention optimisation. Future research is expected to see greater integration of just-in-time adaptive interventions within MRTs. |
