Note: SCQ-A, Smoking Consequences Questionnaire-Adult. The mean score of each domain is reported. The scale is scored on a Likert scale of 0–10. 0, completely unlikely; 1, extremely unlikely; 2, very unlikely; 3, somewhat unlikely; 4, a little unlikely; 5, a little likely; 6, somewhat likely; 7, very likely; 8, extremely likely; and 9, completely likely. An example of a question is “cigarettes keep me from overeating.” The scale measures the beliefs about the consequences of smoking a cigarette. Post hoc testing found no significant differences between inpatients and outpatients with schizophrenia on the SCQ, except for inpatients rating higher stimulation/state enhancement as compared with outpatients (5.7 ± 2.0 vs 5.0 ± 2.1, t = −3.29, adjusted P = .013).
