Description: IMPACT, a disease-specific measure of health-related quality of life (HRQOL) in paediatric inflammatory bowel disease (IBD). The goals of this thesis were to assess IMPACT's sensibility, validity and reliability. Using Feinstein's principles a qualitative and 'quantitative' assessment of sensibility was conducted. The patient and physician participants strongly endorsed the sensibility of IMPACT. The IMPACT total score showed excellent test-retest reliability with an intraclass correlation coefficient of 0.90. The internal consistency rating was also excellent with a Cronbach's alpha of 0.96. Construct validity testing was conducted because of the lack of a gold standard with which to assess HRQOL. All constructs supported the validity of the questionnaire for measuring HRQOL in paediatric IBD patients. No significant influence of patient diagnosis (Crohn's disease or ulcerative colitis) or age was noted. A patient's assessment of their HRQOL appears to be most influenced by their current status, rather their disease course over the past year.
