Background: Co-occurrence of drinking and smoking is prevalent in undergraduate students. A drinker self-schema―cognition about the self as the drinker―is a common identity in undergraduates and a well-known predictor of drinking behaviors. Given that smoking commonly occurs in the context of drinking, a drinker self-schema may be a cognitive mechanism to motivate co-occurring alcohol and tobacco use (i.e., cross-substance facilitation hypothesis). This study was to determine whether the drinker self-schema influences the processing of drinking- and smoking-related information and facilitates the co-occurrence of alcohol and tobacco use in undergraduate students who drink and smoke but do not self-identify as smokers. Methods: This study was the second phase of a 2-phase study. Of the 330 who completed phase 1 (online survey), 99 completed the phase 2 study. Phase 2 was an in-person session that included a computerized information processing task to measure endorsements and response latencies for drinking- and smoking-related attributes, and a computerized Timeline Followback that was used to measure 90-day alcohol- and tobacco-use behaviors. The 5-item drinker self-schema scale, administered in phase 1, was used to measure the strength of the drinker self-schema. Results: A higher drinker self-schema score was associated with more endorsements of positive attributes for drinking and smoking, fewer endorsements of negative attributes for smoking, faster processing of agreements with positive alcohol-use-related attributes, higher levels of drinking and smoking, and more days of co-occurring alcohol and tobacco use. Conclusions: Findings provide preliminary evidence to support the cross-substance facilitation hypothesis that the drinker self-schema facilitates the processing of not only drinking-related but also smoking-related stimuli and behaviors. Undergraduates who have higher drinker self-schema scores may be vulnerable to co-occurring alcohol and tobacco use.
