Detecting college binge drinkers using an extended time frame.

Collegiate binge-drinking is estimated at 44% nationwide, yet epidemiological studies typically limit estimates of binge drinking to episodes during the prior 2 weeks. This study hypothesized that a group of students will have binged on alcohol during the past 3 months but not within the past 2 weeks, and therefore would not be detected using the standard 2-week time frame. Forty males and 72 females who reported drinking alcohol within the past 3 months were included in this study. Fifty-four of the student drinkers (48.2%) were classified as binge drinkers using the prior 2-weeks time criterion, whereas 88 (78.6%) were identified as bingers using the prior 3 months as the criterion. Over one third (38.6%) of the students who binged during the past 3 months would not have been identified as bingers using a 2-week detection period. Furthermore, age, church attendance, alcohol-related consequences, and age of first intoxication were the same regardless of whether bingers had binged in the past 2 weeks or the past 3 months. In contrast, recent binge drinkers reported more frequent alcohol consumption than the 3-month bingers.

Progression of consequences among heavy-drinking college students.

Among a sample of 180 male and 226 female undergraduates, 84.2% reported a heavy drinking episode (5+ drinks for men, 4+ for women) within the previous 90 days. Principal-components analysis revealed 3 alcohol-related problem factors among the heavy drinkers (Careless Behavior, Risky/Reckless Behavior, and Authority Problems). Nearly all heavy drinkers experienced a careless behavior that was due to drinking (92.7%), and many reported a risky/reckless behavior (60.2%), yet only one third (33.9%) experienced an authority problem. Guttman scaling procedures revealed a progression from Careless Behavior to Reckless/Risky Behavior to an Authority Problem. Heavy drinkers with an authority problem drank more frequently, consumed more when drinking, endorsed more alcohol expectancies, and reported earlier ages of initial and regular drinking than other groups.

Hypothesized simple factor structure for the Alcohol Expectancy Questionnaire: confirmatory factor analysis.

This study proposed and tested a theoretical factor structure for the Alcohol Expectancy Questionnaire (AEQ; S. A. Brown, M. S. Goldman, A. Inn, & L. R. Anderson, 1980). Factors were hypothesized to (a) reflect either positive or negative reinforcement, and (b) target either personal feelings or social contexts, resulting in 4 hypothesized factors (Social Enhancement, Social Coping, Personal Enhancement, Personal Coping). Participants were 180 male and 226 female undergraduates who completed the AEQ and additional self-report measures. Confirmatory factor analysis revealed that the hypothesized model fit the data. Post hoc adjustments further improved the model. Finally, a higher order factor model fit the data best. Factors correlated in hypothesized ways with other measures: (a) Only Personal Coping expectancies correlated with negative affect; (b) self-efficacy to resist drinking for emotional relief correlated highest with Personal Coping; and (c) self-efficacy to resist social pressure to drink correlated highest with Social Enhancement. Correlations with B. C. Leigh and A. W. Stacy's (1993) Drinking Expectancy Questionnaire indicated congruent and divergent validity.
