Brief summary
Alcohol is a major modifiable risk factor for breast cancer in women, yet this is not widely understood by health practitioners or policy makers, let alone the general population. The investigators aim to test the effects of a targeted alcohol and lifestyle brief intervention for women attending breast screening services, to improve knowledge of alcohol as a risk factor for breast cancer and reduce harmful alcohol use.
Interventions
BEHAVIORALalcohol brief intervention
Nested within the lifestyle health promotion provided in both conditions, participants randomised to the experimental condition will receive an alcohol brief intervention. The strong evidence-base for alcohol brief intervention, amplified by Co-Investigators' Smith and Bragge's (BehaviourWorks) approaches to applied behaviour change, has provided the framework for the development of the alcohol brief intervention used in this study. This intervention comprises personalised feedback on alcohol consumption levels, comparison to gender/age drinking norms, and information and behaviour-change content regarding alcohol consumption (i.e. negative-framed messaging around alcohol risks and harms, positive-framed messaging on the health benefits of reducing alcohol intake, alcohol harm reduction strategies).
BEHAVIORALlifestyle health promotion
Lifestyle health promotion specific to physical activity and maintaining a healthy weight, developed to be relevant to women attending breast screening services, will be provided.
