The Short Inflammatory Bowel Disease Questionnaire (SIBDQ) is a written, self-administered instrument measuring quality of life in IBD. We assessed the validity of an interactive voice response system (IVRS) as a new mode of administering the SIBDQ.


An IVRS was designed using prerecorded questions to collect data via touchtone telephone. Subjects with Crohn's disease (CD) or ulcerative colitis (UC) were randomized into 2 groups with different orders of administration: written, self-administered followed by IVRS (S-I) or IVRS followed by written, self-administered (I-S). Half of the S-I group was also randomized to receive a second IVRS. Sixty-four subjects were studied: 30 in S-I, 34 in I-S.


The mean SIBDQ scores were not different between written and IVRS modes (P = 0.26) with r = 0.93. IVRS scores were lower in active than inactive CD (36.1 +/- 9.6 versus 54.7 +/- 8.6, P < 0.001) and lower in active than inactive UC (40.8 +/- 9.6 versus 59.8 +/- 10.0, P < 0.001). Mean scores correlated highly with disease activity indices, and were not different between first and second IVRS administrations (P = 0.85) with r = 0.92. IVRS had excellent internal consistency (Cronbach alpha = 0.90).


IVRS administration of the SIBDQ yields results similar to written self-administration, with excellent procedural validity, test-retest reliability, and internal consistency.
