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.

Objective: The factor structure of responses to the twenty-eight-item General Health Questionnaire (GHQ-28) in a sample of 277 Nigerian antenatal women was examined. Method: Principal Component Analysis (PCA) and Varimax rotation were used. Results: A four factor structure interpretable as social dysfunction, somatic-anxiety, depression-anxiety, and severe depression was obtained. Conclusion: Although the factor structure in this sample is similar to that previously reported with this instrument, the factor loadings, particularly for the anxiety subscale differed. Thus, the factor structures of the GHQ may differ depending on the cultural background of the sample.

The aim was to examine the psychometric properties of the Arabic 12-item General Health Questionnaire in a sample of university students. A sample of 157 university students was screened using this questionnaire and the Hopkins Symptom Checklist-90. A standardized clinical interview using SCID was conducted on a subset of screened students. Reliability, validity, and factor analysis of the questionnaire were evaluated. Using factor score discrimination between cases and noncases was also evaluated. The Arabic version of the GHQ-12 proved to be reliable as indicated by Cronbach alpha of .86. The best balance between sensitivity and specificity was found at the General Health Questionnaire cut-off point of 15/16: at this threshold, sensitivity was .88 and was paired with a specificity of .84. Principal component analysis with varimax rotation identified three factors, namely, Factor A (general dysphoria), Factor B (lack of enjoyment), and Factor C (social dysfunction). Factors A and C discriminated between clinically distressed and clinically nondistressed subjects. The General Health Questionnaire-12 as a whole is a reliable and valid screening tool in university settings.

17077 Background: The cancer load in India is enormous and majority of the cases present in an advanced stage. There is no valid translation of 12-item General Health Questionnaire (GHQ-12) in Kannada, which is a simple but indispensable tool in the comprehensive cancer care (both for metastatic and in adjuvant settings). Therefore we thought of developing and validating the GHQ-12 Questionnaire into Kannada language. Methods: The study was conducted at kidwai memorial institute of Oncology, Bangalore, a tertiary cancer center with an annual attendance of 16,000 new cases. We have chosen educated patients who can speak and write both English and Kannada. We used ’forward-backward’ translation procedure into Kannada. We used scores from 0–3 for the Questionnaire. Total score for both languages was calculated. Internal consistency was assessed by Cronbach's alpha coefficient. Validity was performed using convergent validity. Finally, the factor structure of the questionnaire was extracted by performing principal component analysis using oblique factor solution. Results: A total of 118 patients with various malignancies were entered into the study. The mean age was 36.8 ± 12.1 years. The mean GHQ score was 21.6 ± 9.1 for the English and 22.6 ± 8.1 for Kannada. Reliability analysis showed satisfactory result (Cronbach's alpha coefficient = 0.79). The principal component analysis with oblique rotation solution showed that the GHQ-12 was a measure of psychological morbidity with four -factor structure that jointly accounted for 48 % of the variance. Conclusions: The Kannada version of the GHQ-12 is a reliable and valid instrument with a good structural characteristic. It can be used for measuring psychological well being at our institute for those patients who can read and write only Kannada. No significant financial relationships to disclose.

The One

The 12-item General Health Questionnaire (GHQ-12) is a widely used screening instrument. One- and two-factor structures have been identified in some countries. In Brazil, the best factor structure is still unclear. This study aimed at knowing its factorial validity and reliability, and testing the one-factor and two-factor models. The participants were 7,512 Brazilian physicians. They answered the GHQ-12 and demographic questions. Unrotated (one-factor) and rotated (two-factor) structures of the GHQ-12 were extracted by principal component analysis. Confirmatory factor analyses (ML) were used to compare the one- and two-factor solutions. The two-factor model fitted the data better than the one-factor one. Those two factors were depression and social dysfunction, and they showed themselves to be directly correlated to one another. They also showed adequate reliability coefficients. The two-factor model is remarkably adequate, showing better fit indices, although it is acceptable to admit a common factor, which could be defined as psychological distress.

Male school children (N 241), all aged 16 years, and 144 men facing redundancy completed the 60 item version of the General Health Questionnaire. Data from the two groups was analysed separately using unrotated first principal components analysis followed by oblique rotation. The unrotated first principal component accounted for 23% of the variance in the school group, and 13.2% in the group facing redundancy. No subsequent component accounted for more than 6.1% of the variance. For both samples the first five components were subjected to an oblique rotation. Results were discussed in relation to previous findings of the GHQ. The factor structure was found to be unstable across groups. The implications of these findings were considered in the context of proposed subscales of the GHQ.
