Abstract [en]

Goals:To evaluate validity, reliability, and responsiveness of the Short Health Scale (SHS) in irritable bowel syndrome (IBS) patients.Background:Subjective health assessment is central when treating patients with IBS. The Short Health Scale is a quick 4-item questionnaire covering most aspects of subjective health that has been validated for inflammatory bowel disease.Study:To test validity, 451 patients with IBS (mean age, 38 y; 81% females) completed the SHS and questionnaires assessing IBS symptom severity (IBS-SSS), gastrointestinal (GI)-specific anxiety (VSI), and quality of life (IBSQOL). To evaluate reliability and responsiveness to changes, the questionnaires were repeated after 2 weeks in 18 patients, and after 12 weeks in 212 patients who had completed a patient-education program.Results:Validity was documented with (1) gradually increasing mean scores for all 4 SHS items with increasing IBS-SSS (Pless than0.0001), and (2) correlations between the 4 SHS items and the corresponding items from the other subjective health assessment tools [item 1 (symptom burden): =0.67, item 2 (daily function): =-0.44 to -0.46, item 3 (disease-related worry): =-0.51 to 0.57, item 4 (general well-being): =-0.34 to -0.46, Pless than0.0001]. Reliability was confirmed (Spearman greater than0.7 and intraclass correlations greater than0.7). Responsiveness was good with responders to the patient-education program (IBS-SSS reduction 50 points) having significant reductions in 3 of the SHS items (Pless than0.05), and borderline change for the fourth SHS item (P=0.06).Conclusions:SHS is a health measure that shows promising evidence of validity, reliability, and responsiveness in IBS patients. It is quickly completed and evaluated, which supports its usefulness in the busy clinical practice.
