The two-factor structure was the one suggested by the author of the original English version of the GHQ-12 [16]. The models were tested for both the scoring method; for the bimodal method, the diagonally weighted least squares estimator was used and all variables were considered as ordered ...

Each item is rated on a four-point scale (less than usual, no more than usual, rather more than usual, or much more than usual); and for example when using the GHQ-12 it gives a total score of 36 or 12 based on the selected scoring methods. The most common scoring methods are bi...
Employing the recommended method of scoring (ranging from 0 to 12), the mean GHQ score was 3.7 (SD = 3.5). Reliability analysis showed satisfactory result (Cronbach's alpha coefficient = 0.87). Convergent validity indicated a significant negative correlation between the GHQ-12 and global quality...
The GHQ-12 showed a sensitivity of 68% and a specificity of 70% when only cases meeting the criteria for specific DSM III-R disorders were considered. The sensitivity was better for certain individual disorders and the overall performance was marginally improved when scoring was made according to...

Each item is rated on a four-point scale (less than usual, no more than usual, rather more than usual, or much more than usual) and it gives a total score of 12 or 36 on the basis of the scoring method selected. The most common scoring methods are bimodal (0-0-1-1) and Likert...
In addition, the impact of method effects on the reliability of the global GHQ-12 scores was also evaluated. The combined results of this study support the view that the GHQ-12 is a unidimensional measure that contains spurious multidimensionality under certain scoring schemes (corrected and Likert...
Modification of responses scoring from the standard one – GHQ to CGHQ has not improved the validity of questionnaires. Lower validity coefficients of GHQ-28, in comparison to GHQ-12 validity are the effect of greater influence of somatic dis- ease on the results acquired in this scale version...
Mental health was assessed using the GHQ-12, a 12-item questionnaire often used to screen for general (non-psychiatric) mental health problems in primary care settings. The Likert method of scoring was employed, with response options ranging from 0 (“Not at all”) to 3 (“Much more than...
