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? The change in rate between the intervention-phase slope and the maintenance-phase slope was −4.39, statistically significant at p < .025. → Joelle Fingerhut 2022

q2 · i? · quant-synthesis · r2
Model 1 of the HLM meta-analysis applied to maintenance observations, which occurred "between 4 and 224 days" after the last intervention session among the 51 participants (23%) with a maintenance phase. No standardized effect size is printed.
"The change in rate between the slope of the intervention phase and the slope of the maintenance phase was −4.39, γ̂200 = −4.39, t(3399) = −2.86, p < .025."
Discussion¶
Related Claims¶
- Behavioral skills training and other trainings raise DTT implementation fidelity from a low baseline of 40.61% to over 90% accuracy by the end of training — related
- In a meta-analysis of single-case studies, participants trained with complete behavioral skills training had significantly higher DTT implementation fidelity than those trained with only one, two, or three BST components — related
- DTT implementation fidelity declines slightly after training ends, though the decline may reflect outliers — possibly the same claim (merge candidate)
- DTT implementation accuracy increases by 1.33 with each additional observation during the intervention phase — related
- Educator training improves implementation fidelity of interventions for students with disabilities, with a large mean effect size of g = 1.08 — related
