Validity and reliability of the health-related questionnaire IBDQ-32 in Mexican patients with inflammatory bowel disease.

Inflammatory bowel disease comprises two conditions: ulcerative colitis and Crohn's disease. Inflammatory Bowel Disease Questionnaire 32 (IBDQ-32) is a specific questionnaire which has been translated from English into Spanish and validated. In the Spanish-speaking countries of America it has not been validated. The aim was to determine the psychometric properties, validity and reliability of the Mexican version of the IBDQ-32 questionnaire. A total of 316 patients with inflammatory bowel disease and 100 healthy controls participated in the study. The questionnaires IBDQ-32 and SF-36 were issued on two occasions (separated by 15 days). The psychometric properties of the Mexican version of the IBDQ-32 questionnaire were determined. Patients with inflammatory bowel disease had an impaired quality of life compared to healthy controls. There were no differences between ulcerative colitis and Crohn's disease in the total scores of IBDQ-32 and its domains. The internal consistency reliability was good. The intraclass coefficient showed good reliability (repeated measurement) for total scale and all four subscales. Factor analysis explained variance is higher than 50% therefore is considered adequate/acceptable. The correlation between IBDQ-32 and SF-36 showed a satisfactory association. The social domain is the only one that presented a ceiling effect. The Mexican version of the IBDQ-32 quality of life questionnaire is valid and reliable. This sample included the entire spectrum of inflammatory disease (remission and activity) and was comparable when assessing quality of life with the SF-36 generic questionnaire.

The Short Health Scale: a valid and reliable measure of health related quality of life in English speaking inflammatory bowel disease patients.

Health related quality of life in inflammatory bowel disease is influenced both by disease activity as well as by the psychosocial characteristics of the individual patient. The Short Health Scale (SHS) is a four-part visual analogue scale questionnaire using open-ended questions that are designed to assess the impact of inflammatory bowel disease on a health related quality of life. The four dimensions include bowel symptoms, activities of daily life, worry and general wellbeing. It has previously been validated in Swedish and Norwegian speaking patients. To evaluate the SHS in an English speaking inflammatory bowel disease population. Four hundred and ninety Crohn's disease and ulcerative colitis patients completed the SHS. Individual SHS items were correlated with Inflammatory Bowel Disease Questionnaire (IBDQ) dimensions and with disease activity to assess validity. Test-retest reliability was assessed in 38 patients who completed the Short Health Scale two weeks apart. All four items correlated with corresponding IBDQ dimensions with correlation coefficients ranging from -0.66 to -0.74 (all p values<0.001). In addition, total SHS scores correlated with total IBDQ scores in both Crohn's disease (-0.836) and ulcerative colitis (0.797). There was a stepwise increase in Short Health Scale scores with increasing disease activity (all p values<0.001). Reliability was confirmed with test-retest correlations ranging from 0.70 to 0.89 (all p values<0.005). The Short Health Scale is a valid and reliable measure of health related quality of life in English speaking inflammatory bowel disease patients.
