In a large sample of subjects with schizophrenia, McGrath et alArticle factor analyzed not only symptom and prodrome indicators but also indicators of function in child, adolescent, and adult periods. Nine factors covered traditional (hallucinations, negative, disorganized, affective, Schneiderian first-rank) as well as novel domains (scholastic, child/adolescent sociability, prodromal, and disability/impairment). Factor scores in all domains demonstrated significant familiality, offering a range of phenotypes for genetic analyses.
