AIM:To evaluate rational and experiential intelligence in irritable bowel syndrome (IBS) sufferers.METHODS:We recruited 100 subjects with IBS as per Rome criteria(50 consulters and 50 non-consulters) and 100 healthy controls,matched by age,sex and educational level.Cases and controls completed a clinical questionnaire(including symptom characteristics and medical consultation)and the following tests:rational-intelligence(Wechsler Adult Intelligence Scale,3rd edition);experiential intelligence(Constructive Thinking Inventory);personality(NEO personality inventory); psychopathology(MMPI-2),anxiety(state-trait anxiety inventory)and life events(social readjustment rating scale).Analysis of variance was used to compare the test results of IBS-sufferers and controls,and a logistic regression model was then constructed and adjusted for age,sex and educational level to evaluate any possible association with IBS.RESULTS: No differences were found between IBS cases and controls in terms of IQ (102.0 ±10.8 vs 102.8±12.6), but IBS sufferers scored significantly lower in global constructive thinking (43.7±9.4 vs 49.6±9.7). In the logistic regression model, global constructive thinking score was independently linked to suffering from IBS [OR 0.92 (0.87-0.97)], without significant OR for total IQ.CONCLUSION: IBS subjects do not show lower rational intelligence than controls, but lower experiential intelligence is nevertheless associated with IBS.
