The Alternative Model of Personality Disorders distinguishes between the severity of personality dysfunction (Criterion A) and individual differences in personality disorder expression (Criterion B). Several Criterion A measures exist, but few studies have compared these measures with each other. Moreover, debates about whether the constructs of Criteria A and B are redundant (i.e., weak incremental validity) should be framed around how different Criterion A measures perform relative to others. This study of 204 undergraduate students evaluated multiple measures of Criterion A. These measures were strongly correlated with Criterion B, but evidenced incremental validity (39% of outcomes, 5% average additional variance explained) with outcomes of psychopathology and interpersonal impairments, and less consistent incremental validity with suicidality, aggression, and mental health utilization. We discuss how these results inform the construct of Criterion A relative to Criterion B and evaluate strengths/weaknesses of Criterion A measures.

人格障碍的替代模型区分了人格障碍的严重程度（标准 A）和人格障碍表达的个体差异（标准 B）。存在若干标准 A 措施，但很少有研究将这些措施相互比较。此外，关于标准 A 和 B 的结构是否多余（即弱增量效度）的争论应该围绕标准 A 衡量指标相对于其他衡量指标的不同表现展开。这项对 204 名本科生的研究评估了标准 A 的多项措施。这些措施与标准 B 密切相关，但证明了与精神病理学和人际关系障碍结果的增量有效性（39% 的结果，5% 的平均额外方差解释），并且不太一致具有自杀倾向的递增效度，侵略和心理健康利用。我们讨论这些结果如何告知标准 A 相对于标准 B 的构造，并评估标准 A 措施的优势/劣势。
