General Health Questionnaire-28: psychometric evaluation of the Slovak version

Examined the reliability and validity of the Slovak version of the General Health Questionnaire (GHQ-28) in patients (aged 22-70 yrs) with rheumatoid arthritis. The internal consistency and the factor structure of the GHQ-28 are also investigated. Reliability figures and the intercorrelations of the scales indicate that the psychometric qualities of the GHQ-28 in Slovakia are satisfactory. However, at least 6 out of the 28 items appeared to fit better to a different subscale from the original one. General health ratings were more closely associated with subscale anxiety/insomnia. The outcomes are discussed in the light of Western European results. An appendix of the GHQ-28 is provided. (PsycINFO Database Record (c) 2002 APA, all rights reserved)
