Title: Fibromyalgia, Soft Tissue Disorders, Regional and Specific Clinical Pain Syndromes Poster II
Session Type: ACR Poster Session C
Session Time: 9:00AM-11:00AM
Background/Purpose:
The Fibromyalgia Impact Questionnaire – Revised (FIQR) [1] has been in wide use since Bennett et al revised the original FIQ[2]. While the instrument was originally validated and analyzed from questionnaires completed in person on computers, there has been no similar study of the FIQR completed in an online questionnaire. This presentation hopes to address this research gap.
Methods:
Potential participants included persons aged 21-89 with self-report of a provider diagnosis of fibromyalgia. Participants responded to an email from a fibromyalgia support and advocacy non-profit that described the study purpose and led them to a confidential link to an online survey with a unique identifier. The survey consisted of two standardized questionnaires: FIQR and the Five Facet Mindfulness Questionnaire. The sample was further profiled with a 16-item investigator-designed questionnaire that collected clinical and demographic information. Data were collected between November 2012 and January 2013. This study was approved by the Institutional Review Board of Oregon Health and Science University, Portland, Oregon. The statistical analysis from the 2009 manuscript was repeated in order to have similar comparisons. This included item analysis and questionnaire properties using basic statistics, reliability item analysis, and Cronbach alpha. Significance of specific means was analyzed using Tukey honestly significantly differences (HSD) for unequal sample size.
Results: A total of 4,986 respondents represented all 50 states in the United States and 30 countries. FIQ-R scores demonstrated moderate to severe fibromyalgia with the majority of subjects (59%) scoring ≤ 60. The mean total score was 63.4 ± 17.8 indicating that our population had a slightly higher FIQR score than originally reported. The average age was 52.2 ± 10.6. Most (74%) were symptomatic with FM for over 10 years. 53% reported not working outside the home due to their FM, despite being highly educated (47% college graduates and post graduate degrees). Individual items were compared as well as subscores. All subscores were higher than the original paper but within the standard deviations. The correlations between individual items and subscales were comparable to the original study.
Conclusion: The characteristics of the FIQR when administered online are similar to the original paper. However, our sample indicates that the population averages for the FIQR Function, Impact, and Symptom subscales as well as the Total score were all higher than originally reported.
