The Minnesota Multiphasic Personality Inventory-3 (MMPI-3) includes a new Impulsivity (IMP) scale designed to assess for poor impulse-control and non-planful behavior, which was added to broaden the utility of the instrument. The current study aimed to examine the criterion and incremental validity of the IMP scale. A university student sample ( = 1,440) and a community sample oversampled for externalizing tendencies ( = 231) were used for this purpose, and IMP scores were compared to scores on various well-validated criterion measures of impulsivity and externalizing psychopathology. To examine the scale's incremental validity, hierarchical multiple regression analyses were conducted to determine whether IMP adds to other MMPI-3 Specific Problem (SP) scales in the prediction of relevant criteria. The IMP scale primarily showed meaningful correlations with the Negative Urgency and Positive Urgency on the UPPS-P. Significant correlations were also observed with the cognitive, behavioral, disinhibition, and lifestyle domains of various psychopathy measures, as well as measures of antisocial personality disorder and substance use. The IMP scale scores accounted for incremental variance in most of the directly relevant criterion measures above and beyond scores of other MMPI-3 SP scales. Several important caveats, limitations, and future directions are discussed.
明尼苏达多相人格量表-3（MMPI-3）包含一个新的冲动性（IMP）量表，旨在评估冲动控制能力差和无计划行为，该量表的加入是为了扩大该工具的效用。本研究旨在检验IMP量表的效标效度和增量效度。为此，使用了一个大学生样本（n = 1440）和一个因外化倾向而过度抽样的社区样本（n = 231），并将IMP得分与各种经过充分验证的冲动性和外化精神病理学效标测量的得分进行比较。为了检验该量表的增量效度，进行了分层多元回归分析，以确定IMP在预测相关标准时是否能补充其他MMPI-3特定问题（SP）量表。IMP量表主要与UPPS-P上的消极紧迫性和积极紧迫性显示出有意义的相关性。在各种精神病态测量的认知、行为、去抑制和生活方式领域，以及反社会人格障碍和物质使用的测量中也观察到了显著相关性。IMP量表得分在上述大多数直接相关的效标测量中，除了其他MMPI-3 SP量表得分之外，还解释了增量方差。本文讨论了几个重要的注意事项、局限性和未来方向。
