Research indicates a robust association between personality and substance use and misuse. The high prevalence and pervasive detrimental impacts of alcohol use disorder (AUD) and smoking of tobacco necessitate more studies designed to identify factors closely associated with these outcomes in specific populations. The analyses reported in the present paper concern the relative utilities of five measures of personality and personality pathology rated by three sources (self, informant, and interviewer) in predicting AUD and regular smoking in a representative sample of 987 older adults, an understudied and uniquely vulnerable population. All measures and sources contributed to the predictions, with notable parallels as well as some important differences identified across substances and sources of information. In particular, low agreeableness robustly predicted AUD and smoking across self- and informant-reports. High interviewer-rated borderline personality pathology also strongly predicted AUD. Model fit indices suggested that measures of personality and personality pathology have stronger utility in predicting AUD as compared to regular smoking. These findings have important implications for the assessment of older adults in research and clinical settings and for the understanding of enduring risk factors for substance misuse later in life. Multi-source personality information is valuable for generating a complete picture of the relationship between personality and substance misuse.

研究表明人格与物质使用和滥用之间存在密切关联。酒精使用障碍 (AUD) 和吸烟的高患病率和普遍的有害影响需要更多的研究来确定与特定人群中这些结果密切相关的因素。本文报告的分析涉及由三个来源（自我、线人和采访者）评定的五种人格和人格病理学测量在预测 987 名老年人的代表性样本中的 AUD 和经常吸烟的相对效用，这是一个未被充分研究且独一无二的样本。弱势群体。所有措施和来源都对预测做出了贡献，具有显着的相似之处以及在物质和信息来源之间确定的一些重要差异。尤其是，低宜人性有力地预测了自我报告和线人报告中的澳元和吸烟情况。高面试官评价的边缘人格病理学也强烈预测澳元。模型拟合指数表明，与经常吸烟相比，人格和人格病理学测量在预测 AUD 方面具有更强的效用。这些发现对于在研究和临床环境中评估老年人以及了解晚年物质滥用的持久风险因素具有重要意义。多源人格信息对于生成人格与物质滥用之间关系的完整图景很有价值。模型拟合指数表明，与经常吸烟相比，人格和人格病理学测量在预测 AUD 方面具有更强的效用。这些发现对于在研究和临床环境中评估老年人以及了解晚年物质滥用的持久风险因素具有重要意义。多源人格信息对于生成人格与物质滥用之间关系的完整图景很有价值。模型拟合指数表明，与经常吸烟相比，人格和人格病理学测量在预测 AUD 方面具有更强的效用。这些发现对于在研究和临床环境中评估老年人以及了解晚年物质滥用的持久风险因素具有重要意义。多源人格信息对于生成人格与物质滥用之间关系的完整图景很有价值。
