Smoking abstinence expectancies are beliefs about negative and positive short-term psychological and physiological consequences of not smoking. The Smoking Abstinence Expectancies Questionnaire (SAEQ) is a widely used Patient-Reported Outcome Measure (PROM) to assess smoking abstinence expectancies. It has four subscales: negative mood, somatic symptoms, harmful consequences, positive consequences. Although studied from a psychometric perspective, the SAEQ needs further evaluation. Clinimetrics, and its Clinimetric Criteria for Patient-Reported Outcome Measures (CLIPROM), offers a robust method to evaluate the SAEQ. We verified construct validity and sensitivity of the Italian version of the SAEQ applying CLIPROM criteria. A total of 293 adult Italian smokers were consecutively enrolled at two smoking cessation clinics and assessed via the SAEQ. Item Response Theory models (i.e., combining Rasch and Mokken analyses) were used to test construct validity and sensitivity. The total score of the SAEQ was not found to be unidimensional but each SAEQ subscale score was. PSI (0.90) indicated that the total score of the SAEQ could reliably discriminate between respondents with different levels of the trait under assessment, whereas SAEQ subscales on negative mood and harmful consequences could reliably distinguish between different groups but not between different subjects (PSI ranging from 0.77 and 0.78). Overall, the total score of the SAEQ is a sensitive screening PROM and can be used at smoking cessation clinics to discriminate between subjects with different levels of smoking abstinence expectancies. SAEQ subscales should be used to detect severity and subjective burden of a wide range of expected effects of nicotine abstinence.
