title: Monitoring drinking behaviour and motivation to drink over successive doses of alcohol.
abstract: The objective of this study was to compare alcohol urge, drinking behaviour and mood across two beverage conditions (alcohol/soft drink), over multiple drinks. Forty-five (22 men) participants completed two conditions (alcohol/soft-drink). Baseline alcohol urge and mood was measured before an initial drink consumed (0.2 g/kg alcohol or lemonade). Four drinking phases, which provided alcohol and lemonade, followed. Alcohol urge, mood and liking/enjoyment of beverages were measured. Participants' typical drinking habits were recorded, allowing comparisons across drinking factors. Alcohol urge was greater in the alcohol condition (P<0.03), which positively correlated with liking and drinking enjoyment of the alcohol beverage (P<0.04). Binge drinking and weekly alcohol consumption positively related to alcohol urge during the first half of the alcohol condition (P<0.02). Feeling stimulated was positively related to alcohol urge (P<0.01). Sip latency was quickest for alcohol in the alcohol condition (P<0.001) and did not increase over time as in the soft-drink condition (P<0.001). This study presents a paradigm in which alcohol motivation can be assessed within more typical drinking occasion parameters. Urge related to alcohol's positive reinforcing effects. As more alcohol was consumed, a disassociation of liking and wanting alcohol occurred, indicating that different processes may underlie behaviour during different periods of a drinking occasion.
