Range of total school performance score is 501–550. Range of psychotic experiences score is 0–4 and range of auditory/visual hallucinations score is 0–2. Model 1 is adjusted for sex, age, ethnicity, maternal educational level, maternal nonverbal IQ and whether the questionnaire on psychotic experienceswas completed alone or with help from others. Model 2 is additionally adjusted for nonverbal IQ at age 6 years.
