OBJECTIVE: To develop a new scaled GHQ version (GHQ-28) for use in Primary Care in Spain. DESIGN: Principal components analysis of the parental version (GHQ-60) with subsequent selection of 7 items with higher loadings for the first 4 components. SITE: Three Primary Care Centres in the metropolitan area of Bilbao. PARTICIPANTS: A total of 202 patients coming from a prior study on frequent visits to Primary Care clinics. MAIN MEASUREMENTS: Comparison between the new and the authorised version of GHQ-28 in discriminating between psychiatric and non-psychiatric cases, diagnosed independently by psychiatric interview. RESULTS: Whereas the structure of two scales was similar to that described previously, the other two scales showed higher variability with the inclusion of new items and a combination of others previously ascribed to different measurement constructs. No significant difference (P=.63) was observed between both versions regarding their discriminant validity. CONCLUSIONS: The most stable GHQ-28 scales were social dysfunction and depression. The variability found among the other scales could be explained by the non-specificity of psychiatric symptoms presented in Primary Care.
