The LIFE-UP, an instrument for prospectively following course for psychiatric disorders, has been extended to include Psychiatric Status Ratings (PSRs) for the DSM-III-R anxiety disorders panic (with and without agoraphobia), agoraphobia without panic, generalized anxiety disorder, social phobia, and simple phobia. This paper reports data on the reliability and validity of the LIFE-UP as used in the Harvard/Brown Anxiety Disorders Research Program. We found generally good reliability for the PSRs, both inter-rater and long-term test-retest. The reliability coefficients for the rater-administered instruments were very similar to those for the self-reports, suggesting that a large proportion of the variance was due to subject variability rather than rater variability. Reliability for the beginning of the year of follow-up was very similar to that for the time just before the interview. In addition, correlations with other measures of psychosocial function or anxiety symptomatology provided evidence for the external validity of the PSRs as measures of psychiatric morbidity.
LIFE - UP是一种用于前瞻性追踪精神疾病病程的工具，现已扩展到包括对《精神疾病诊断与统计手册》第三版修订本（DSM - III - R）中焦虑症的精神状态评定（PSR），这些焦虑症包括惊恐障碍（有或无广场恐惧症）、无惊恐发作的广场恐惧症、广泛性焦虑症、社交恐惧症和单纯恐惧症。本文报告了在哈佛/布朗焦虑症研究项目中使用的LIFE - UP的信度和效度数据。我们发现，PSR的信度总体良好，包括评分者间信度和长期重测信度。评分者施测工具的信度系数与自我报告的信度系数非常相似，这表明大部分变异是由于受试者的变异性而非评分者的变异性。随访年初的信度与访谈前即刻的信度非常相似。此外，与心理社会功能或焦虑症状学的其他测量方法的相关性为PSR作为精神疾病发病率测量指标的外部效度提供了证据。
