• The Wechsler Abbreviation Scale for Intelligence-2 Vocabulary (VOC) and Matrix Reasoning (Matrix) subtests and the Wide Range Achievement Test 4 (WRAT4) Reading subtest were used to assessing IQ and reading ability, respectively [58, 59]. Higher values present better performance. • The Global Assessment of Functioning score (GAF) was employed to assess general functioning. Lower values present more functional impairments, with values below 70 being associated with at least moderate symptoms [57]. • Several rating scales were administered to determine psychiatric symptoms:o BPRS = Brief Psychiatric Rating Scale- Expanded Version: 24 items: 1 (not present), 2 (very mild), 3 (mild), 4 (moderate), 5 (moderately severe), 6 (severe), 7 (extremely severe) [50,51,52]o SIPS = Structured Interview for Psychosis Risk Syndromes [53]: symptoms are rated on the following scale: 0 (absent), 1 (questionably present), 2 (mild), 3 (moderate), 4 (moderately severe), 5 (severe but not psychotic), 6 (severe and psychotic). | ||||
