We compared the item content of three commonly used scales of psychiatric symptoms [the broad-band Psychiatric Symptom Index (Ilfeld) and two narrow-band scales, the Center for Epidemiologic Studies-Depression Scale (Radloff) and the State-Trait Anxiety Inventory (Spielberger)], with diagnostic criteria and criterion-based symptoms for Major Depressive Episode and Generalized Anxiety Disorder as they appeared in DSM-IV. The Psychiatric Symptom Index and the Center for Epidemiologic Studies-Depression Scale each measured 7 of 9 criterion-based symptoms of Major Depressive Episode. The Psychiatric Symptom Index and State-Trait Anxiety Inventory each measured 5 of 8 domains for Generalized Anxiety Disorder. The Psychiatric Symptom Index had comparable content validity to the narrow-band measures. All met a majority of DSM-IV criteria for depression and anxiety, supporting their applicability for current research.
我们将三种常用的精神症状量表[宽带精神病症状指数（伊尔费尔德）以及两种窄带量表，即流行病学研究中心抑郁量表（拉德洛夫）和状态-特质焦虑量表（斯皮尔伯格）]的条目内容，与《精神疾病诊断与统计手册》第四版（DSM-IV）中出现的重度抑郁发作和广泛性焦虑障碍的诊断标准及基于标准的症状进行了比较。精神病症状指数和流行病学研究中心抑郁量表各自测量了重度抑郁发作9项基于标准的症状中的7项。精神病症状指数和状态-特质焦虑量表各自测量了广泛性焦虑障碍8个领域中的5个。精神病症状指数与窄带测量方法具有相当的内容效度。所有量表均符合DSM-IV中关于抑郁和焦虑的大多数标准，支持它们在当前研究中的适用性。
