  • ASRS, Adult ADHD Self Report Scale, continuous scoring method (0–4 on each item).

  • AQ-10, Autism quotient abridged 10-item version, continuous scoring method (0–3 on each item).

  • a Endorsement of two or more items in the 5PQ.

  • b Clumsiness defined as reported performance below average in physical education in school at age 12 years (‘In elementary school (when you were about 12 years), did you perform worse than average in physical education (i.e. ball games, coordination, agility)?’). A yes response suggests clumsiness, whereas a no response does not.
