Multicenter Study Comparative Study
Psychiatric comorbidities in a community sample of women with fibromyalgia.
Prior studies of careseeking fibromyalgia (FM) patients often report that they have an elevated risk of psychiatric disorders, but biased sampling may distort true risk. The current investigation utilizes state-of-the-art diagnostic procedures for both FM and psychiatric disorders to estimate prevalence rates of FM and the comorbidity of FM and specific psychiatric disorders in a diverse community sample of women. Participants were screened by telephone for FM and MDD, by randomly selecting telephone numbers from a list of households with women in the NY/NJ metropolitan area. ⋯ Risk of lifetime anxiety disorders, particularly obsessive compulsive disorder and post-traumatic stress disorder, was approximately 5-fold higher among women with FM. Overall, this study found a community prevalence for FM among women that replicates prior North American studies, and revealed that FM may be even more prevalent among racial minority women. These community-based data also indicate that the relationship between MDD and FM may be more complicated than previously thought, and call for an increased focus on anxiety disorders in FM.

Two important influences on pain underestimation by health care professionals were investigated by varying specific cues with reference to underestimation of patients' pain: when observers are not allowed to talk to patients and when observers expect social cheating. One hundred and twenty health care professionals watched videotaped facial expressions of pain patients and estimated their pain. The first group only saw the faces, the second group was given patients' self-reports in addition and the last group was given a context cue priming them to expect cheating in addition to faces and patients' ratings. ⋯ Those viewing the face without patients' ratings underestimated pain to a greater extent than health care professionals provided with patients' ratings. Health care professionals primed to expect cheating underestimated pain as much as those seeing only patients' faces. Therefore, both accounts, verbal report as important but missing cue as well as an alerted cheating detection device, could account for underestimation.
