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.

Trial registration: ClinicalTrials.gov identifier: NCT04896151.

在过去一个月有死亡/自杀意念的退伍军人中发现明尼苏达多相人格量表-3 (MMPI-3)的模拟漏报
背景:我们在识别有自杀高风险的退伍军人方面仍然取得了有限的成功,部分原因是他们不愿透露自杀的想法。目的:本研究采用模拟组实验设计来评估MMPI-3对上月死亡/有自杀意念的退伍军人自杀风险漏报的评估能力。材料与方法:39名退伍军人(男性占53.85%)随机分为标准低报组和模拟低报组,提供MMPI-3及附属测量的有效数据。我们研究了(1)模拟MMPI-3(以L和K量表得分为指标)的漏报是否会影响SUI量表的得分,(2)这些影响是否会延伸到最简单的自杀和非自杀措施的漏报,以及(3)MMPI-3 L和K量表是否会逐渐预测和区分最近有死亡/自杀念头的退伍军人,这些退伍军人被指示如实回答和被指示少报。结果:各组在K上的得分差异显著(g = 0.99, m - simulation = 57.83, m - standard = 43.72),但在l上无差异(g = 2.00;m - simulation = 46.33, m - standard = 66.81)和附带措施的自杀风险(g = 0.69-0.79)。K分数显著预测群体成员资格,并逐渐增加到l。讨论:讨论了这些发现的局限性和临床意义。结论:MMPI-3 K,而不是L,量表得分最可靠地反映自杀意念和意图的防御性报告和精神病理,更广泛。然而,大量的自杀意念和意图漏报可能未被发现。试验注册:ClinicalTrials.gov标识符:NCT04896151。

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.
