The Longitudinal Interval Follow-up Evaluation (LIFE) is an integrated system for assessing the longitudinal course of psychiatric disorders. It consists of a semistructured interview, an Instruction booklet, a coding sheet, and a set of training materials. An interviewer uses the LIFE to collect detailed psychosocial, psychopathologic, and treatment information for a six-month follow-up interval. The weekly psychopathology measures ("psychiatric status ratings") are ordinal symptom-based scales with categories defined to match the levels of symptoms used in the Research Diagnostic Criteria. The ratings provide a separate, concurrent record of the course of each disorder initially diagnosed in patients or developing during the follow-up. Any DSM-III or Research Diagnostic Criteria disorder can be rated with the LIFE, and any length or number of follow-up intervals can be accommodated. The psychosocial and treatment information is recorded so that these data can be linked temporally to the psychiatric status ratings.
纵向间隔随访评估（LIFE）是一个用于评估精神障碍纵向病程的综合系统。它由一份半结构化访谈、一本指导手册、一张编码表和一套培训材料组成。访谈者使用LIFE收集六个月随访间隔内详细的社会心理、精神病理学和治疗信息。每周的精神病理学测量（“精神状态评定”）是基于症状的顺序量表，其类别定义与研究诊断标准中使用的症状水平相匹配。这些评定提供了对最初在患者中诊断出或在随访期间出现的每种障碍病程的单独、同步记录。任何DSM-III或研究诊断标准中的障碍都可以用LIFE进行评定，并且可以适应任何随访间隔的长度或数量。记录社会心理和治疗信息，以便这些数据能够在时间上与精神状态评定相联系。
