Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Intraindividual randomization over weeks (each person randomized tens or hundreds of times) increases data points per person and allows estimation of heterogeneity in within-person causal effects. → Breitwieser 2024

q2 · i? · theoretical · r3
Analytical argument about micro-randomized trial design in this Perspective. The design is described as randomization "performed within individuals over time (i.e., intraindividual randomization)," an evolution of single-case designs.
"Repeated randomization within individuals increases the number of data points per person, thus allowing researchers to draw more firm conclusions compared to a standard randomized controlled trial with the same sample size."
Discussion¶
Related Claims¶
- 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
- Micro-randomized trials with mobile data allow explicit testing of time-varying contextual moderators of intervention effectiveness — a broader claim this one bears on
