| Abstract: | Abstract The present study compared two different methods of assessing alcohol and caffeine use in a community sample of adults over a one-year period. Daily reporting of beer/wine intake was more stable over time and showed higher correspondence with Quantity-frequency measures than daily reporting of hard liquor use. Coffee and tea use showed high temporal stability and good alternate form reliability, though a tendency to underreport typical use of coffee use was observed. The psychometric properties of substance use measures appear to vary with type of beverage consumed and report format. |
