Abstract: The aim of this study was to assess the reliability and to evaluate the factor structure of General Health Questionnaire (GHQ-28) with reference to the inclusion and exclusion criteria in subscales. 260 university and college students responded for the General Health Questionnaire -28 and Split-half Reliability and Cronbach’s Alpha were used to assess the reliability of the instrument. Factor Structure was assessed using Factor analysis. The results of the study revealed that the instrument is having higher level of Split-Half reliability(0.76) and Good Internal Consistency(a=0.85) The Factor analysis of factor structure revealed that item factors were loaded in to three main factors where those three factor accounted for a cumulative variance of 33.217%, whereby the items belonging to Somatic Symptoms were loaded to the same component (with one item variation), the items belonging to Social Dysfunction and Severe Depression scales were also preserved. But the Items belonging to Anxiety Insomnia subscale were distributed among other subscales, suggesting a possibility of three scales GHQ.
Keywords: General Health Questionnaire (GHQ-28), evaluate the factor structure, Split-Half reliability.
