Psychosocial risk factors like low socio-economic status, chronic family or work stress, social isolation, negative emotions (e.g., chronic depression or acute anxiety), and negative personality patterns such as Type-D-pattern or hostility, may contribute significantly to the development and adverse outcome of coronary heart disease. Therefore, systematic screening for psychosocial risk factors in cardiological practice is recommended in order to initiate adequate intervention strategies, e.g., to involve additional psychosocial counselling or treatment. Reliable methods to assess psychosocial risk factors are: (1) standardized, structured interviews; (2) standardized questionnaires, and (3) 'single-item' questions to be included into the cardiologists' clinical interviews. While structured interviews should be restricted to trained professionals, questionnaires are easily to administer, and have frequently been used in the field of cardiology. 'Single item' questions are sufficiently reliable and the most timesaving way to screen for psychosocial factors. For clinical practice, a two-step evaluation is recommended: firstly, cardiologists should include 'single-item' questions into their routine interview and/or use questionnaires in order to screen for a potential problem. Secondly, if problems are indicated, patients should be passed to qualified professionals for structured clinical interview. Instruments of all three methods are briefly presented, and implications for further treatment are discussed.
