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 i3 Achievement scale scores correlated negatively with CAARS A (r=-0.43, p<0.005), CAARS E (r=-0.43, p<0.005) and SWAN Attention (r=-0.44, p<0.005): the lower the motivation score, the greater the inattention. → Volkow ND 2011
q3 i? Correlations between Achievement scores and hyperactivity ratings were not significant. → Volkow ND 2011

q3 · i3 · associational · r2
Correlational analysis within the ADHD group between the MPQ Achievement scale and symptom ratings on CAARS and SWAN; printed correlations of "r=-0.43" and "r=-0.44" with inattention measures, all p<0.005. Hyperactivity correlations were not significant.
"which was significant for the CAARS A (r=-0.43, p<0.005), CAARS E (r=-0.43, p<0.005) and the SWAN Attention dimension (r=-0.44, p < 0.005) (Figure 2); the lower the scores in the Achievement scale the greater the inattention."
Discussion¶
Related Claims¶
- In adults with ADHD, dopamine D2/D3 receptor and DAT availability in the reward pathway correlate positively with trait motivation — related
- Adults with ADHD score lower on the MPQ Achievement scale, a surrogate trait measure of motivation, than controls — related
- Positive Emotionality correlates with midbrain D2/D3 receptor availability in ADHD adults, while Negative Emotionality and Constraint do not — related
- Impairment on WM, STM, and/or motivation is associated with more inattention symptoms, medication use, and lower IQ scores — a broader claim this one bears on
- ADHD adults show lower D2/D3 receptor and DAT availability in nucleus accumbens and midbrain than controls — related
