Abstract
Background: We continue to have limited success in identifying Veterans at high risk of suicide, due in part to reticence of disclosing suicidal ideation.
Aims: This study used a simulated groups experimental design to evaluate the MMPI-3's ability to assess suicide risk underreporting in Veterans with past-month death/suicide ideation.
Materials and methods: Thirty-nine Veterans (53.85% men) were randomized to standard and simulated underreporting groups and provided valid data on the MMPI-3 and collateral measures. We examined (1) whether simulated underreporting on the MMPI-3 (indexed by L and K scale scores) impacts SUI scale scores, (2) if these effects generalize to underreporting on extratest suicide and non-suicide measures, and (3) if MMPI-3 L and K scales incrementally predict and differentiate between Veterans with recent death/suicide ideation who were instructed to answer honestly and those instructed to underreport.
Results: Groups scored significantly differently on K (g = 0.99: Msimulation = 57.83, Mstandard = 43.72), but not L. Underreporting captured by K generalized to lower MMPI-3 SUI scale scores (g = 2.00; Msimulation = 46.33, Mstandard = 66.81) and collateral measures of suicide risk (g = 0.69-0.79). K scores significantly predicted group membership and added incrementally to L.
Discussion: The limitations and clinical implications of these findinga are discussed.
Conclusion: MMPI-3 K, but not L, scale scores most reliably capture defensive reporting of suicidal ideation and intent and psychopatholpgy, more boradly. However a signifcant amount of underreporrting of suicidal ideation and intent may go undetected.
期刊介绍:
An excellent resource for researchers as well as students, Social Cognition features reports on empirical research, self-perception, self-concept, social neuroscience, person-memory integration, social schemata, the development of social cognition, and the role of affect in memory and perception. Three broad concerns define the scope of the journal: - The processes underlying the perception, memory, and judgment of social stimuli - The effects of social, cultural, and affective factors on the processing of information - The behavioral and interpersonal consequences of cognitive processes.
