A four-item suicidal ideation subscale of the General Health Questionnaire-28 (GHQ-28) has been used previously to assess suicidal ideation on the basis of its face validity. In order to further validate its use, this study compared scores on this scale with scores on a well-established suicidal intent scale. There was a significant correlation between scores of that subscale & the self-report component as well as the overall score of the suicidal intent scale, thereby confirming its validity in providing a standardized method for comparing suicidal ideation in different populations.
