INTRODUCTION: The Patient Reported Outcomes Measurement Information System (PROMIS®) Smoking Initiative has developed six item banks for assessing smoking behaviors and biopsychosocial correlates of smoking among daily and nondaily adult cigarette smokers. This paper presents new validity evidence for the item banks including correlations of the item banks to the existing legacy measures of smoking (Fagerström Test of Nicotine Dependence (FTND), Questionnaire of Smoking Urges (QSU), and the Wisconsin Inventory of Smoking Dependence Motives (WISDM)). METHODS: Using data from a follow-up sample (N = 491) and a community sample (N = 369) of adult daily and nondaily smokers, we replicated the findings from Edelen et al. (2014a) and examined the correlations of legacy smoking measures with the new item bank scores. RESULTS: Preliminary validity findings were largely replicated with the new data. Correlations among the banks are moderate and bank score associations with measures of smoking behavior, quitting history, and other PROMIS measures follow expected patterns (e.g., nicotine dependence is most strongly associated with smoking quantity and time to first cigarette of the day; health and psychosocial expectancies are most related to quitting recency and interest). Correlations of bank scores with legacy measures are moderate to strong. The PROMIS nicotine dependence scores were most strongly associated with the legacy instruments. CONCLUSIONS: These analyses provide strong evidence for the validity of the PROMIS Smoking item banks in two independent samples.
