BackgroundThe Goldberg's 30-item General Health Questionnaire (GHQ-30) is used as a screening instrument for psychological distress in the general population. GHQ-30 has been widely used as a unitary measure, but several underlying factors have been identified in previous studies based on factor analyses.AimTo analyze the internal consistency and the factor structure of the Polish version of GHQ-30 in the group of somatic and psychiatric patients’ subpopulations. Differences in factor structure among those two groups might have important implications for how the test is used in those populations.MethodsA total of 1473 patients (807 psychiatric and 666 somatic) were included into the study. A total score was calculated with Likert method. The principal factor analysis with orthogonal varimax normalized rotation was used for the factor extraction.ResultsThe GHQ-30 was found to have high internal consistency. The factorial analysis conducted for the whole group, as well as for psychiatric and somatic patients separately, showed that two factors labeled as followed can be abstracted from the global scale: “depression and anxiety” and “interpersonal functioning and general coping”. These factors jointly account for 54,2% – 62,3% of the variance.ConclusionsResults showed that GHQ-30 may be used both as a unitary measure using full-scale sores and allows to get more detailed information about individual's intra- and interpersonal functioning.

AIM: The aim of the study is to analyze the internal consistency; validity and factor structure of the twelve item General Health Questionnaire for the Macedonian general population.MATERIAL AND METHODS: Data came from nationally representative sample of 1603 randomly selected Macedonians all aged 18 years or older.RESULTS: The mean GHQ score in the general sample was found to be 7.9 (SD = 4.3). The results revealed a higher GHQ score among women (M = 8.91, SD = 4.5) compared to men (M = 6.89; SD = 4.2). The participants from the rural areas obtained a lower GHQ score (M = 7.55, SD = 3.8) compared to participants coming from the urban areas (M = 9.37, SD = 4.1). The principal component analysis with oblique rotation (direct oblimin) with maximum likelihood procedure solution was performed and the results yielded a three factor solution which jointly accounted for 57.17% of the total variance: Factor I named social management (items 1, 3, 4, 6, 7 and 8); Factor II stress (items 2, 5 and 9) and Factor III named self-confidence (items 10, 11 and 12). Its factor structure is in line with representative research from other population groups.CONCLUSION: The GHQ-12 can be used effectively for assessment of the overall psychological well-being and detection of non-psychotic psychiatric problems among the Macedonian population.
