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.
q3 i? Cronbach's alpha for the eight DESR items was 0.90 in the full sample, indicating the items measure a unitary construct. → Surman Craig B. H. 2013

q3 · i? · associational · r2
Psychometric analysis of the eight self-report DESR items across the combined ADHD and non-ADHD sample. The study reports "Cronbach’s alpha for the eight scale items was 0.90 in the entire study sample (ADHD and non-ADHD subjects) indicating high internal consistency for these items."
"Cronbach’s alpha for the eight scale items was 0.90 in the entire study sample (ADHD and non-ADHD subjects) indicating high internal consistency for these items."
