State levels of positive and negative affect were assessed at baseline and several postdrinking periods using the Positive and Negative Affect Scales (PANAS; Watson, Clark, & Tellegen, 1988). The PANAS is a 20-item, self-report measure on which respondents indicate [using scales anchored at 1 (very slightly or not at all) and 5 (extremely)] the extent to which they currently feel 10 positive states (PA; e.g., interested, excited) and 10 negative states (NA; e.g., distressed, nervous). Internal consistency was good for both the PA (α = .90) and NA (α = .81) subscales.
