This study seeks to evaluate the construct validity of the Symptom Assessment-45 by investigating the instrument's correlation with selected scales from the Personality Assessment Inventory and life-event data in a sample of 93 psychiatric patients. The life-event data used in the study included: education and employment, as well as history of suicide attempts, psychiatric hospitalizations, medical problems, hallucinations, and paranoid ideation. Bivariate correlations were computed to explore the associations among the SA-45 scales and the validity criteria. The results indicated that the SA-45 scales demonstrated adequate convergent and divergent validity with target scales from the PAI. They were also found to be meaningfully associated with a variety of life event variables. These findings add to the emerging body of evidence corroborating the convergent and discriminant validity of the SA-45.
本研究旨在通过调查人格评估量表中选定的量表与生活事件数据与 93 名精神科患者样本的相关性，评估症状评估-45 的结构效度。研究中使用的生活事件数据包括：教育和就业，以及自杀企图、精神病住院、医疗问题、幻觉和偏执观念的历史。进行了双变量相关分析，以探讨 SA-45 量表与有效性标准之间的关联。结果表明，SA-45 量表与 PAI 中的目标量表表现出足够的聚合和区分效度。它们还与各种生活事件变量有意义地相关。这些发现为支持 SA-45 的聚合和区分效度的新兴证据提供了补充。
