Session Title: General Rehabilitation Case & Research Report
Session Time: 11:15am-12:45pm
Location: Research Hub - Kiosk 1
Disclosures: Bennett Stothers: Nothing to disclose
Objective: To develop a picture-based version of the 10 items in the limitations of activities (LoA) section of the SF-36, because those with limited language comprehension or literacy face problems completing written questionnaires related to their health and treatment. Then, to evaluate the comparability of the picture-based versus the written version.
Design: Prospective, cohort study.
Setting: International Collaboration on Repair Discoveries (ICORD), University of British Columbia, Canada and community dwelling adults.
Participants: N= 101volunteers (43 male, 58 female); age 18-93 years: educational level: 52 post-secondary, 44 high school grades 10-12, 5 grade 9 or less.
Interventions: First participants completed our picture-based SF-36LoA developed using Poser © software version 11.0 (VIJO California); then described verbally and in writing what they understood each picture to mean. Next they completed the English text version of the SF-36 LoA score in order to reduce bias. Finally, participants suggested where pictures could be altered to increase information capture.
Main Outcome Measures: A quadratic weighted kappa score was used to analyze the correlation between the individual picture versus text based items in both questionnaires as an equivalent to an intra-class correlation coefficient. Demographics: compared using descriptive statistics.
Results: N=101 subjects rated their health as: 26.7% excellent, 25.7% very good, 29.8% good, 10.9% fair and 6.9% poor. Analysis showed strong correlation between text-based SF-36LoA questions and the picture-based visual score – VSF-36LoA – (ICC=0.98) with question 10 correlating highest (ICC=0.90) and question 2 lowest (ICC=0.82).
Conclusions: Our VSF-36LoA is the first picture-based version of the SF-36 LoA domain; evaluation indicated that the picture-based version conveyed comparable meaning and had good correlation to the English text version in subjects with adequate literacy. This good correlation and global need warrants further development to aid those with limited literacy or language comprehension. Future directions should evaluate its use in a cohort representative of those in need.
