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? Among diagnosed youth, two or more comorbid disorders elevated risk for slow PS (OR = 2.20, p < .001) while one comorbid disorder did not (OR = 1.19, p = .42). → Braaten EB 2020

q3 · i? · associational · r3
Logistic regression in 636 diagnosed youth compared comorbidity levels, controlling for age, sex, and medication. Similar patterns held within ADHD (two or more additional diagnoses: OR = 1.88, p = .02) and anxiety (OR = 2.72, p = .04), but not ASD.
"the presence of any second diagnosis (i.e., two conditions) over any one condition did not significantly increase the risk for slow PS (OR = 1.19, 95% CI 0.77 – 1.85, p = .42); however, having any 3 or more disorders did increase risk for slow PS (OR = 2.20, 95% CI 1.39 – 3.48, p < .001)."
Discussion¶
Related Claims¶
- Inattention is the only psychopathology symptom dimension associated with slow processing speed, and it does not explain the associations with ASD or psychosis — related
- Psychosis, ASD, and ADHD-Inattentive Type independently elevate risk for slow processing speed relative to referred youth without diagnoses — related
- More current comorbid conditions are associated with higher DESR scores in adults with ADHD — related
- The association between ADHD and DESR is not fully explained by comorbid psychiatric disorders — related
- All diagnostic groups of referred youth, including those without full diagnoses, show processing speed below the population norm — related
- Adolescents with ADHD respond more slowly than non-ADHD peers across all conditions, and color-shape binding slows responses in both groups
