Identification of suicide attempters by means of MMPI profiles
Abstract:
Used multivariate procedures to determine whether psychiatric patients who had made a suicide attempt immediately prior to hospitalization (N = 161) could be differentiated from nonsuicidal psychiatric patients (N = 161). Multivariate analysis of variance and cluster analysis failed to identify differences in the MMPI data of suicidal and nonsuicidal patients. In contrast, discriminant analysis produced a modest degree of differentiation that generally was maintained in the cross-validation.
Insights
This study investigated if Minnesota Multiphasic Personality Inventory (MMPI) data could differentiate between psychiatric patients who attempted suicide and those who did not. While some methods failed, discriminant analysis showed modest success in distinguishing between these groups.
Area of Science:
- Psychiatry
- Psychological Assessment
- Clinical Psychology
Background:
- Differentiating suicidal from nonsuicidal psychiatric patients is crucial for effective treatment.
- The Minnesota Multiphasic Personality Inventory (MMPI) is a widely used tool for psychological assessment.
Purpose of the Study:
- To determine if multivariate procedures could distinguish between psychiatric patients with and without recent suicide attempts.
- To evaluate the utility of MMPI data in identifying individuals at high risk for suicide.
Main Methods:
- Multivariate analysis of variance (MANOVA)
- Cluster analysis
- Discriminant analysis
- Cross-validation
- Comparison of MMPI data between suicidal (N=161) and nonsuicidal (N=161) psychiatric patients.
Main Results:
- MANOVA and cluster analysis did not reveal significant differences in MMPI data between the two groups.
- Discriminant analysis achieved a modest level of differentiation between suicidal and nonsuicidal patients.
- The observed differentiation was generally consistent upon cross-validation.
Conclusions:
- While not definitively separable by all multivariate methods, MMPI data shows some potential for differentiating suicidal from nonsuicidal psychiatric patients.
- Discriminant analysis offers a promising, albeit modest, approach for identifying individuals with a recent history of suicide attempts.
- Further research may refine these methods for improved clinical utility in suicide risk assessment.
