Patients knowledge of pregnancy-related issues in inflammatory bowel disease and validation of a novel assessment tool (CCPKnow)
Alimentary Pharmacology and Therapeutics, 05/30/2012
Selinger CP et al. – Crohn's and Colitis Pregnancy Knowledge Score, a novel knowledge assessment tool of pregnancy and Inflammatory bowel diseases (IBD), demonstrated excellent test characteristics. The authors found that nearly half of the women with IBD had poor knowledge, identifying a pressing need for better education.Methods
- Discriminate ability of ‘CCPKnow’ was validated in four groups with different levels of IBD knowledge. Reliability and readability were tested by Cronbach- α and Flesch-Kencaid.
- Construct validity was subsequently assessed against general IBD knowledge (CCKnow) in 145 women with IBD.
- Associations between patient factors and knowledge were studied.
- Median CCPKnow scores differed significantly between the validation groups (P<0.001).
- CCPKnow displayed excellent internal consistency, reliability (Cronbach-α 0.94), readability (reading age 9 years) and close correlation with CCKnow (Spearman's ρ 0.64; P<0.001).
- Of 145 patients, 44.8% had poor, 27.6% adequate, 17.3% good and only 10.3% very good knowledge.
- Better knowledge was associated with Caucasian ethnicity, higher income, having a partner, having children, Crohn's and Colitis Association membership, longer disease duration and Crohn's disease.
