在一项多地点职业研究中，对 202 名患有严重精神疾病的人检查了知名仪器的可靠性。我们检查了阳性和阴性综合症量表 (PANSS) 的受试者间可靠性以及 PANSS、罗森伯格自尊量表、医疗结果研究简表 36 (SF-36) 和生活质量访谈的内部一致性和重测可靠性。大多数量表具有良好的可靠性，组内相关系数 (ICC) 和系数 alpha 均高于 0.70。然而，随着时间的推移，SF-36 量表通常不太稳定，特别是社会功能量表 (ICC = 0.55)。受教育程度较低的受访者和少数族裔的重测可靠性较低。我们建议在未来的多中心研究中密切监测心理测量问题。
Reliability of well-known instruments was examined in 202 people with severe mental illness participating in a multisite vocational study. We examined interrater reliability of the Positive and Negative Syndrome Scale (PANSS) and the internal consistency and test-retest reliability of the PANSS, the Rosenberg Self-Esteem Scale, the Medical Outcomes Study Short Form-36 (SF-36), and the Quality of Life Interview. Most scales had good levels of reliability, with intraclass correlation coefficients (ICCs) and coefficient alphas above .70. However, the SF-36 scales were generally less stable over time, particularly Social Functioning (ICC = .55). Test-retest reliability was lower among less educated respondents and among ethnic minorities. We recommend close monitoring of psychometric issues in future multisite studies.
