[…] The questionnaires were formatted for use on Survey Monkey (Portland, OR, USA), a commercial online survey technology. In addition to the FIQR, the original questionnaire (FIQ) and the 36-Item Short Form Health Survey (SF-36) (Rand Corporation, Santa Monica, CA, USA) were posted on the Survey Monkey site for the FM subjects. The SF-36 is a widely used generic instrument that measures health-related quality of life [] and has a well-documented use in the evaluation of FM patients [,]. The online site for the healthy controls and RA, SLE, and MDD subjects did not contain the FIQ or SF-36 questionnaire. The questionnaire for healthy controls and RA, SLE, and MDD patients differed from the questionnaire for FM patients in that the term 'health issues' was substituted throughout the questionnaire for 'fibromyalgia' (this questionnaire, the SIQR, is available in the online version of this article; Additional data file ). To ascertain that FM subjects still had widespread pain and that the healthy controls and RA, SLE, and MDD patients did not have widespread pain, the questionnaire contained a 'yes/no' item as to the body areas in which they currently had pain. This item contained 24 separate locations: left shoulder, right shoulder, left jaw, right jaw, left upper back, right upper back, left arm, right arm, left hand, right hand, left lower back, right lower back, left hip, right hip, left thigh, right thigh, left knee, right knee, left foot, right foot, mid upper back, mid lower back, front of chest, and neck.The survey was sent out to 659 FM patients in August 2008, and 208 responded within 2 weeks (a response rate of 32%). After approximately 200 FM subjects had completed the questionnaire, the results were downloaded from the Survey Monkey server into Excel spreadsheets (Microsoft Corporation, Redmond, WA, USA) and the survey was closed to further participation for the FM patients. The RA/SLE and the MDD sites were kept open for about 3 months as it was challenging to find RA, SLE, and MDD patients who did not have widespread pain. The FIQR scoring algorithm was processed on the Excel spreadsheet and then transferred to STATISTICA statistical software (StatSoft, Inc., Tulsa, OK, USA) for the statistical analyses. As a check on data entry and scoring, the Excel spreadsheet was also loaded into version 14 of SPSS statistical software (SPSS Inc., Chicago, IL, USA) and the scoring algorithm was entered into SPSS syntax. Correlation and verification of the STATISTICA data and results were performed by RW and KDJ. […]
