We examined the test-retest reliabilities of reported and objective measures of smoking, and the intercorrelations among these measures, in acutely psychotic patients with schizophrenia to determine whether severe psychiatric illness affects the utility of these variables. All measures demonstrated good test-retest reliability. Objective measures of smoking were consistently intercorrelated and should be the preferred outcome measures in studies testing strategies to reduce smoking.
