VALLEJO, Miguel A.  and  GRUPO ICAF et al. The general health questionnaire (GHQ-28) in patients with fibromyalgia: psychometric characteristics and adequacy. Clínica y Salud [online]. 2014, vol.25, n.2, pp.105-110. ISSN 2174-0550.  https://dx.doi.org/10.1016/j.clysa.2014.06.005.

Fibromyalgia is a syndrome that involves multiple symptoms, including widespread musculoskeletal pain, emotional and cognitive problems, and adjustment difficulties. The General Health Questionnaire (GHQ-28) has been widely used, even if little data exist on its use in patients with fibromyalgia. A sample of 301 patients with fibromyalgia was studied, analyzing the goodness of the questionnaire and its structure. High anxiety levels (X = 1.5), social dysfunction (X= 1.56) and somatic symptoms of GHQ-28 (X= 1.67) were obtained. The reliability is adequate (Cronbach's α = .94) and the factor structure of four factors analyzed conforms to that proposed by the authors of the questionnaire. The conclusion is that GHQ-28 has been useful to explore the psychological symptoms in patients with fibromyalgia.
