Abstract
AIM:
To evaluate rational and experiential intelligence in irritable bowel syndrome (IBS) sufferers.
METHODS:
We recruited 100 subjects with IBS as per Rome Ⅱ 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 rat ional intel l igence than cont rols, but lower
experiential intelligence is nevertheless associated with IBS.
