Slim addendum to the 2026 07 27 Tars Nathan Working Partnership Playbook

The Adult ADHD Self-Report Scale (ASRS v1.1, Kessler et al. 2005) is the WHO-recommended screener for adult ADHD. The Wender Utah Rating Scale (WURS-25) provides retrospective childhood-symptom data. Both take <10 minutes to complete. If Nathan completes the ASRS and the score is below the screener-positive threshold (4+ on the 6-item Part A), the ADHD co-occurrence hypothesis becomes less likely. If the score is at or above threshold, the profile is AuDHD, and the playbook needs an additional addendum for the ADHD attentional demand side (task chunking, novelty-seeking, executive function support).

detail does not. "Compared to the ADHD group, the ASD group had AQ scores that were significantly greater, except for attention to detail." The ASD group's advantage is on the social/comm/ imagination/switching axes; the detail axis is similarly elevated in both ADHD and ASD adults. This is exactly Nathan's profile**: his AQ signal is on the non-detail axes (his item 9 endorsement is one of the few strong detail items, but the heavy signal is Imagination + Switching + Social/Comm).

Implication for Nathan's profile: This is the key finding that justifies calibrating the playbook for a 2e hypothesis even without a formal IQ assessment. If Nathan is in the 2e distribution, his self-report profile will systematically under-represent his communicative difficulty (because high verbal ability provides cover) and the masking cost will be higher than the AQ + SRS-2 readings suggest (because the compensatory strategies that produce the cover are not free).
