Detailed Description
The Acceptance and Commitment Therapy is a mindfulness-based intervention which efficacy has been proven in the treatment of depression and anxiety, in stress reduction and in the modification of health- related behaviors in patients with several physical conditions. The application of an acceptance-based program in cardiac patients has revealed high treatment satisfaction and initial evidences of effectiveness in increasing heart-healthy behaviour.
The purpose of the trial is to evaluate the efficacy of a brief group-administered program based on Acceptance and Commitment Therapy in improving patients' ability to address modifiable multiple cardiovascular risk factors and overall psychological well-being, compared with the usual care.

Outcome Measures
Primary Outcome Measures
- Low-density lipoprotein (LDL)cholesterol [Baseline and 12 months]
Change from baseline LDL cholesterol level
- Blood pressure [baseline and 12 months]
Change from baseline resting blood pressure (the mean of 2 measures taken 2 minutes apart with a manual sphygmomanometer)
- Body Mass Index [baseline and 12 months]
Change from baseline Body Mass Index. It is calculated as weight in kilograms divided by height in meters squared
- Psychological Well-Being [Baseline and 12 months]
Change from baseline Psychological Well-Being. It will be measured by the Psychological General Well-Being Inventory. The PGWBI is a self-administered questionnaire composed by six sub-scales: anxiety, depression, positive well-being, self-control, general health and vitality. Higher scores indicate better health.
Secondary Outcome Measures
- Health-related quality of life [Baseline and 12 months]
Change from baseline Health-related quality of life. The Short Form-36 questionnaire for evaluation of Quality Of Life is widely used and gives valuable information on Quality Of Life related to health. The patients' Quality Of Life will be assessed through the following eight fractions: physical function, physical role, general health, social function, experience of pain, mental health, emotional role and vitality.
- Dietary habits [Baseline and 12 months]
Change from baseline dietary habits. They will be assessed through the Mediterranean diet score, a large-scale diet score based on the inherent characteristics of Mediterranean dietary pattern. Questions focused on the frequency of usual consumption of 11 main components of the Mediterranean diet (nonrefined cereals, fruits, vegetables, potatoes, legumes, olive oil, fish, red meat, poultry, full fat dairy products and alcohol).
- Physical activity [Baseline anf 12 months]
Change from baseline physical activity. It will be measured by The International Physical Activity Questionnaire (IPAQ), a self-report questionnaire that assesses the number of days per week and the number of times per day an individual spends doing specific activities.
- Smoking cessation [At 1-year follow-up]
Self-report of smoking status
- Adherence to medication [Baseline and 12 months]
Change from baseline adherence to medication. The Modified Morisky Scale will be used. It is a eight-item self-reported measure of medication taking.
- Exercise capability [Baseline and 12 months]
Change from baseline exercise capability. The exercise capability will be considered as the maximal power (in Watts) reached during an incremental bicycle stress test.
Other Outcome Measures
- Psychological inflexibility [Baseline and 12 months]
Change from baseline psychological inflexibility. It will be measured through the Acceptance and Action Questionnaire-II, a self-report 10-item scale.
