Abstract
AbstractThis paper studies the factorial structure of the 12‐item version of the General Health Questionnaire (GHQ‐12), Dutch translation, in a large Belgian sample (n = 9442) that is representative of the general population. Data was collected from the 2001 Belgian Health Interview Survey. In total, 11 factor‐structure models are tested by means of confirmatory factor analysis. Two models, a two‐factorial model without cross‐loadings and a three‐factorial model with cross‐loadings, prove to have acceptable model‐fit. Given parsimony and the uni‐dimensionality of the subscales, the authors prefer the two‐factorial model over the three‐factorial one. In a next step, it is examined whether a general, second‐order factor can be seen underlying both the two‐ and three‐factorial models. This, however, was only true for the three‐factorial model. Based on correlations with other scales (the revised Symptom Checklist 90, SCL‐90‐R; the MOS Social Support Survey, MOS‐SSS) and a variable on social contacts, the authors suggest that the ‘social dysfunction’ subscale be renamed ‘dysfunction’.
