Information on psychiatric symptoms and diagnoses. The same constructs were measured using different instruments. For example, the Addition Severity Index (ASI) asks "Have you had a significant period of time (that was not a direct result of drug/alcohol use) in which you have experienced hallucinations - saw things or heard voices that other people did not hear or see?" and the medical and psychiatric history evaluation asks about schizophrenia. The definitions of substance abuse have changed in the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders. Also see the Harmonization Information vignette for more details.

Note that the data from the ASI (depression, anxiety, and schizophrenia) contains four levels plus NA. People who did not take the ASI are coded with NA. People who took the ASI but are completely missing an answer to a question are coded as "Missing". Others who are known to not answer (i.e., refused to answer) are coded with "Not Answered".
