Short Health Scale: a valid and reliable measure of quality of life in Dutch speaking patients with inflammatory bowel disease

Abstract

Objectives: Patient reported outcomes are widely used in today’s clinical practice. The Short Health Scale has been proven to be an easy-to-use and reliable measure to evaluate quality of life in patients with inflammatory bowel disease. We aimed to validate this Short Health Scale in Dutch speaking patients.Methods: A total of 157 Crohn’s disease and ulcerative colitis patients (46% male, median age 39 years) completed the Short Health Scale on a tablet during the outpatient clinic. Validity was assessed by correlating both individual and total Short Health Scale scores with short Inflammatory Bowel Disease Questionnaire dimensions and clinical disease activity. Test-retest reliability was assessed in eight patients in stable remission who completed the Short Health Scale a second time after 4–8 weeks.Results: All Short Health Scale items correlated with corresponding short Inflammatory Bowel Disease Questionnaire dimensions (correlation coefficients ranging from −0.403 to −0.833, all p < .01). Short Health Scale scores increased stepwise with increasing clinical disease activity (all p < .001). The results of the Short Health Scale questionnaire remained stable on repeated measurements in patients in remission (rs between 0.699 and 0.994, all p < .01 except for well-being).Conclusions: The Short health Scale is a rapid and valid instrument for measuring quality of life in Dutch speaking patients with Inflammatory Bowel Disease. Its simplicity and usability make it a good candidate for routine care and suitable for home-monitoring of patients.
