背景：为了评估卫生服务的结果，提供者需要简短、反应灵敏、可靠和有效的措施，这些措施可以在临床环境中以最小的成本和负担实施。行为和症状识别量表 (BASIS-32(R)) 是 1984 年开发的一项自我报告测量方法，用于评估心理健康治疗结果。在过去的3年里，我们采用多种方法对工具进行了修订，以提高信度、效度以及对不同心理健康服务接受者群体的适用性。目的：本研究的目的是对修订后的工具进行现场测试，在分析现场测试数据的基础上进行进一步修改，并评估最终版本（BASIS-24）的信度和效度。方法：在美国27个治疗点进行了现场测试。共有2656名住院患者和3222名门诊患者参与。使用因子分析方法、经典测试理论和项目响应理论建模来选择最具辨别力、非冗余的项目，将其纳入工具的最终版本中，并评估其可靠性和有效性。使用项目反应理论模型对工具进行评分。结果：最终工具包括评估 6 个领域的 24 个项目：抑郁/功能、人际关系、自残、情绪不稳定、精神病和药物滥用。重测和内部一致性可靠性是可以接受的。结构效度和判别效度测试支持该工具区分心理健康状况不同群体的能力，及其与其他心理健康指标的相关性。 结论：BASIS-24 的分析支持其从患者角度评估心理健康状况的可靠性和有效性。
Background: To assess outcomes of health services, providers need brief, responsive, reliable, and valid measures that can be implemented in clinical settings with minimal cost and burden. The Behavior and Symptom Identification Scale (BASIS-32(R)) is a self-report measure developed in 1984 to assess mental health treatment outcomes. During the past 3 years, multiple methods were used to revise the instrument to improve reliability, validity, and applicability to diverse groups of mental health service recipients.Objective: The objective of this study was to field test the revised instrument, make further changes based on analysis of the field test data, and assess reliability and validity of the final version (BASIS-24).Methods: A field test was implemented at 27 treatment sites across the Untied States. A total of 2656 inpatients and 3222 outpatients participated. Factor analytic methods, classic test theory, and item response theory modeling were used to select the most discriminating, nonredundant items for inclusion in the final version of the instrument and to assess its reliability and validity. Item response theory modeling was used to score the instrument.Results: The final instrument includes 24 items assessing 6 domains: depression/ functioning, interpersonal relationships, self-harm, emotional lability, psychosis, and substance abuse. Test-retest and internal consistency reliability were acceptable. Tests of construct and discriminant validity supported the instrument's ability to discriminate groups expected to differ in mental health status, and its correlation with other measures of mental health.Conclusions: Analyses of the BASIS-24 supported its reliability and validity for assessing mental health status from the patient's perspective.
