Detailed Description

Participants (convenience sample invited via the party organiser) completed daily questionnaires during the week after New Year's Eve about presence and severity of hangover symptoms.

On day 1 demographics and substance use at New Year's Eve were recorded; on day 7 the Brief Symptom Inventory (BSI) assessed mood over the prior week.

After four weeks, following a drug-free week, the BSI was repeated to provide a reference assessment.
