Psychometric analysis and emotional state in the irritable bowel syndrome (ibs)

Abstract

INTRODUCTION: Data are lacking on psychometric scores and the emotional state in Sri Lankan patients with the irritable bowel syndrome. AIM: To evaluate patients with IBS using a Hospital Anxiety Depression (I IAD) scale and to assess the accuracy of clinical prediction of the emotional state by a non psychia¬trist clinician. METHODS: Data from 30 patients (20 male, median age - 27 years, range 20 - 50) with IBS titling me manning criteria were compared with 44 age and sex matched controls without IBS. Anxiety rating (median, range) was : Patients 11 (5-17) versus Controls 6 (1-17); P<0.05. Depression rating was : Palients 7 (2 -14 ) versus Controls 5 (0-16) P>0.05, Wilcoxon lest. Prediction of emotional state in patients with IBS correlated well with HAD scores in 17 (56%), was inaccurate in 6 (20%) and equivocal in 7 (24%). All patients in whom clinical prediction of emotional state was inaccurate had combined high anxiety and depression scores. CONCLUSION: Sri Lankan patients with IBS have greater prevalence of anxiety state disorders compared with controls. Clinical prediction of the emotional state by an untrained physician was inaccurate. The HAD scale may be of value in clinical decision making for patients with the irritable bowel syndrome associated with emotional state disorders.
