The objective of this study was to determine contextual antecedents to smoking among Korean American emerging adult (KAEA) smokers using ecological momentary assessment. Based on extant theory and data documenting the importance of negative affect (NA) and social context, we examined the extent to which being with friends and NA independently and concomitantly were associated with the likelihood of subsequent smoking, over and beyond other known situational correlates of smoking.', 'Twenty-two KAEA daily smokers recorded their smoking events in real time and participated in short surveys implemented on mobile phones for 7 days. Individual, interpersonal, and situational contexts immediately preceding and during smoking events were examined in comparison to nonsmoking events using a within-subject modeling approach.', 'Both NA and being with friends independently were correlated with increased likelihood of smoking. We also found an interaction showing that the effects of NA on smoking were significant only in presence of friends.
Do momentary negative moods and being with friends precede cigarette use among Korean American emerging adults?
