Juvenile primary fibromyalgia syndrome in an inpatient adolescent psychiatric population.

UNLABELLED: The purpose of this study was to identify the clinical and demographic characteristics of adolescent females admitted to a psychiatric hospital who meet the criteria for Juvenile Primary Fibromyalgia Syndrome (JPFS).

METHODS: Participants (n = 62) were adolescent females, ages 12 to 18 years who were admitted to an inpatient psychiatric unit. The participants completed four questionnaires: The Achenbach Youth Self-Report (YSR), the Children's Somatization Inventory (CSI), the Fibromyalgia Impact Questionnaire modified for children (FIQ-C) and the Pain Symptom Questionnaire (PSQ). Then participants were interviewed to assess the Yunus and Masi JPFS criteria. The interview included an examination of 21 (18 bilateral and 3 control) tender points.

RESULTS: Of the 62 adolescent females enrolled, 52% (n = 32) met criteria for JPFS (i.e. JPFS cases). Both the FIQ and CSI scores were significantly elevated for JPFS cases as compared with non-cases (p = .0001 and p = .0012 respectively). Cases of JPFS also scored significantly higher on the anxiety, depression, and conduct disorder scales of the YSR. No between-group differences were found in reports of physical or sexual abuse. However, a consistently higher percentage of JPFS cases reported physical or sexual abuse as a child.

CONCLUSIONS: Juvenile primary fibromyalgia is highly prevalent in an adolescent inpatient psychiatric unit. This possibility should be taken into consideration when chronic complaints of pain are expressed by patients in this setting, especially in those who have conduct-related issues. The connection between JPFS and abuse history requires further investigation.
