Abstract Objective: The questionnaire Visual Analogue Scale for Irritable Bowel Syndrome (VAS-IBS) has been validated in measuring gastrointestinal symptoms and psychological well-being in patients with IBS. The aim of this study was to additional evaluate the items of VAS-IBS, and to examine correlations in the items measuring psychological well-being and intestinal symptoms´ influence on daily life to attachment in close relationships, self-esteem and coping. Methods: Eighty-one patients with IBS completed VAS-IBS with five VAS items for each gastrointestinal symptom, one item for the psychological well-being, and one item for the intestinal symptoms´ influence on daily life. They also completed the questionnaires Experiences in Close Relationships, the Rosenberg Self-Esteem Scale, and the Sense of Coherence. Correlations between the questionnaires and differences between subgroups were examined. Results: The rating of the item psychological well-being as poor well-being, correlated to a high degree of anxiety in close relationships (rs = -0.293, p = 0.008), low self-esteem (rs = 0.487, p = 0.000), and reduced coping (rs = 0.579, p = 0.000). Psychological well-being correlated to the intestinal symptoms´ influence on the patients´ daily life (rs = 0.515, p = 0.000). Conclusions. By this easy-to-use and brief VAS-IBS questionnaire, the health care professionals get a lot of information not only about physical symptoms, but also about the patient´s psychological well-being.
