Food-related quality of life in inflammatory bowel disease: measuring the validity and reliability of the Turkish version of FR-QOL-29

Abstract

Purpose Food-related quality of life is considerably impaired in patients with inflammatory bowel disease (IBD) and should be widely measured in research and clinical practice. This study aims to translate the FR-QoL-29 instrument to the Turkish language and evaluate its validity and reliability in Turkish patients with IBD. Methods The FR-QoL-29 was forwards and backwards translated into Turkish and the validity and reliability of the FR-QoL-29-Turkish measured at two tertiary hospitals in Ankara, Turkey. Participants completed four questionnaires regarding: sociodemographic; clinical (disease type and activity), and nutritional characteristics (MUST) together with FR-QoL-29-Turkish. In addition, 30 patients repeated the questionnaires after two weeks. collected. Pearson correlation coefficients and Cronbach α were used to assess reliability and validity (p < 0.05). Results A total of 180 participants with IBD (78 Crohn’s disease, 102 ulcerative colitis), with a mean age of 45.9 ± 12.5 years, were included. Bartlett's sphericity test was statistically significant (p < 0.001), meeting the prerequisite for factor analysis, and the adequacy of the sample size for factor analysis was confirmed by a high Kaiser–Meyer–Olkin (KMO = 0.92). Validity was confirmed by factor loadings ranging from 0.310 to 0.858. Item-total score correlations ranged from 0.258 to 0.837 and Cronbach’s α coefficient was 0.96 for the whole questionnaire indicating high internal consistency. Conclusions FR-QoL-29-Turkish is a valid and reliable measure of food-related quality of life in IBD patients with Turkish language. The FR-QoL-29-Turkish gives a comprehensive overview of the main aspects of food quality of life and can be used as a useful tool in both research and clinical practice.

Improving Food-Related Quality of Life in Inflammatory Bowel Disease through a Novel Web Resource: A Feasibility Randomised Controlled Trial

“…The largest study to date in 1221 outpatients with IBD in the United Kingdom [ 13 ], reported a high prevalence of impaired FR-QoL in IBD, with lower scores associated with the number of recent disease flares, reduced IBD-specific quality of life and greater IBD-related distress, with impaired FR-QoL being associated with lower intakes of fibre and several micronutrients. Similar low FR-QoL scores have been observed in people with IBD in both the United States [ 14 ], Australia [ 15 ], New Zealand [ 16 ], and Turkey [ 17 ]. A study in active and inactive IBD [ 3 ] showed that the strongest predictor of FR-QoL was IBD symptom severity.…”
