Alcohol assessment using wireless handheld computers: a pilot study

Jay M Bernhardt et al. Addict Behav. 2007 Dec.

Abstract

The present study sought to test the feasibility of measuring quantity and frequency of self-reported alcohol consumption among college students using the Handheld Assisted Network Diary (HAND) by comparing results to a retrospective Timeline Followback (TLFB). A total of 40 undergraduate college students completed a HAND assessment during the two-week study period and completed a TLFB at follow-up. The HAND recorded similar levels of alcohol consumption compared to the TLFB. There were no significant differences in overall alcohol consumption, drinks per drinking day, or heavy drinking days between the two methods of assessment. Handheld computers may represent a useful tool for assessing daily alcohol use among college students.

Figure 1. Difference in drinks per drinking day: HAND - TLFB
Difference = standard drinks per drinking day on TLFB subtracted from standard drinks on HAND. Standard drinks were defined as 12 ounces of beer, 5 ounces of wine or champagne, 3 ounces of fortified wine, or 1.5 ounces of hard liquor. The differences in drinks per drinking day between the two measures were within one standard drink for 64% of participants, were higher within two standard drinks on the HAND for 25% of participants, and were higher within two standard drinks on the TLFB for 38% of participants.
