Subclaims¶

q3 i? In a 15-day micro-randomized trial, 171 children assigned to diaphragmatic breathing, an active control video, or no video showed no main effect of breathing on negative affect or relaxation. → Breitwieser 2024 q3 i? Preregistered moderation analyses indicated the breathing exercise increased relaxation on days when children worried more than usual. → Breitwieser 2024 (2)

Evidence¶

q3 · i? · causal · r?

Micro-randomized trial with 171 children aged 9–13 over 15 study days, randomized daily among a three-minute video-guided slow-paced diaphragmatic breathing exercise, an active control video, and a passive control. Results shown in Fig. 3b.

"There was no main effect of the breathing exercise on either negative affect or relaxation, but preregistered moderation analyses suggested that the breathing exercise increased relaxation on days when children worried more than usual (Fig. 3b)."

q3 · i? · theoretical · r3

Authors' interpretation of the UPWIND moderation result: the same intervention helped on higher-worry days, illustrating time-varying context moderation. Effect size not printed.

"This pattern shows that the effectiveness of the intervention depends on context factors, further highlighting the need for explicitly considering these factors in the implementation of mobile interventions."

Discussion¶

Related Claims¶

• Micro-randomized trials with mobile data allow explicit testing of time-varying contextual moderators of intervention effectiveness — a broader claim this one bears on
• Mobile reminder prompts causally increased children's vocabulary-app study on prompted days (PROMPT micro-randomized trial) — related
