Brief Summary
This study tests the effects of a self-affirmation manipulation on (i) acceptance of a health message detailing the risks of alcohol consumption, (ii) engagement with the health message and (iii) alcohol consumption at 7-day follow-up. Half of the participants complete a self-affirmation manipulation, where they reflect on their most important values, whereas the other half complete a control equivalent, where they reflect on their least important values. Immediately post-intervention, all participants then receive information about the risks of alcohol consumption and complete measures of message acceptance and engagement with the materials. Seven days after intervention, participants self-report their alcohol consumption in the previous 7 days.

Outcome Measures
Primary Outcomes (1)
Alcohol consumption 7 days after intervention
Seven days after the intervention, participants are contacted and asked to report their alcohol consumption over the previous 7-day period via self-report items. Participants report the type of alcohol (e.g., beer, spirit), type of container (e.g., small glass, pint, single measure) and the number of each type of drink they had consumed on each day over the previous 7 days using the adapted version (Armitage, Harris, \& Arden, 2011) of the timeline fallback technique (Sobell \& Sobell, 1992). The total number of units consumed by each participant was then calculated using the UK NHS alcohol unit calculator (NHS Choices, 2013: www.nhs.uk/tools/pages/alcohol-unit-calculator.aspx).

Study Arms (2)
Self-affirmation
EXPERIMENTALParticipants in the self-affirmation arm write about their most important value, reasons why is important and an example of when they enacted that value. This is the Self-affirmation manipulation task as described in the intervention.
Control
ACTIVE COMPARATORParticipants in this arm complete a control equivalent of the self-affirmation task, where they write about their least important value, reasons why is may be important to someone else and an example of when another person may have enacted that value. This is the Control task as described in the intervention.
Interventions
Participants in the self-affirmation condition indicate their most important value, give three examples of why this value is important to them and one example of something they had done to demonstrate its importance.
People in the control condition indicate their least important value, three examples of why that value could be important to someone else, and describe something that person could do to show its importance.
