Subclaims¶

q2 i? Using mobile-collected data, researchers can test how fluctuating internal states (e.g., mood, arousal) and external contexts moderate intervention effects, which was previously difficult because temporal resolution was too coarse. → Breitwieser 2024

Conceptual argument in this Perspective. Prior context effects "have been difficult to test because the temporal resolution of interventions and assessment has been too coarse"; moderators include lesson-of-day, mood, motivation, and arousal at prompting time.

"Using the various data col- lected by mobile devices, micro-rando mized trials allow researchers to explicitly test the effects of time-varying moderators of intervention effec- tiveness."

Discussion¶

Related Claims¶

• Mobile devices enable just-in-time adaptive interventions that flexibly adapt support to students' changing internal and contextual states — related
• Micro-randomized trials estimate within-person causal effects of mobile intervention components with greater statistical power than standard RCTs — a narrower finding that bears on this claim
• Mobile reminder prompts causally increased children's vocabulary-app study on prompted days (PROMPT micro-randomized trial) — a narrower finding that bears on this claim
• Breathing exercise showed no main effect on children's negative affect or relaxation but increased relaxation on higher-worry days (UPWIND trial) — a narrower finding that bears on this claim
