Summary
The General Health Questionnaire-28 (GHQ-28) suicidal ideation subscale is a valid tool for assessing suicidal thoughts. It significantly correlates with established suicidal intent scales, enabling population comparisons.
Area of Science:
- Psychiatry and Mental Health Research
- Psychometric Validation Studies
Background:
- The General Health Questionnaire-28 (GHQ-28) includes a four-item subscale for assessing suicidal ideation.
- Previous use of this subscale relied primarily on face validity for its application.
Purpose of the Study:
- To further validate the use of the GHQ-28 suicidal ideation subscale.
- To compare its scores against a well-established measure of suicidal intent.
Main Methods:
- A comparative study design was employed.
- Scores from the GHQ-28 suicidal ideation subscale were correlated with scores from a validated suicidal intent scale.
Main Results:
- A significant positive correlation was found between the GHQ-28 suicidal ideation subscale scores and both the self-report and overall scores of the suicidal intent scale.
- This indicates strong concurrent validity for the GHQ-28 subscale.
Conclusions:
- The GHQ-28 suicidal ideation subscale is a valid instrument for measuring suicidal ideation.
- Its confirmed validity supports its use as a standardized method for comparing suicidal ideation across diverse populations.
