RecruitingPhase 3Behavioural interventionIntervention to Increase Intention to Change Alcohol/Tobacco Use in Veterans With Chronic DiseaseMany Veterans who have chronic conditions like cardiovascular disease or diabetes smoke or drink too much alcohol, which can worsen the condition. Veterans are asked yearly about drinking/smoking and providers provide a brief advice discussion focused on behavior change. However, many Veterans continue to drink or smoke, and are often not interested in higher-intensity, change-based referrals. The investigators recently piloted MINDSET, an intervention that fills this gap. MINDSET is a proactive, population-based intervention that uses a mailed packet with tailored education about how drinking/smoking relate to the Veteran's condition (heart conditions and/or diabetes), followed by a brief motivational call. The investigators will test MINDSET's effectiveness versus usual primary care on outcomes including intention to change and substance use and evaluate the relationships between these and other variables over time.
