The aim was to present the content of the newly developed observer rating scale of work ability--The Occupational Functioning Scale (OFS)--and its basic psychometric properties. Psychiatric disorders cause functional impairment in several domains, including occupational functioning. The assessment of work-related functioning is often neglected in psychiatric research, partly due to a lack of reliable and valid instruments. The validity of OFS was evaluated by comparing it with other work ability measures (SAS-work, Work Ability Index, sickness absence) and to non-work-ability related measures [Inventory of Interpersonal Problems (IIP), Symptom Check List - General Symptomatic Index (SCL-90-GSI)] in 150 patients with depressive or anxiety disorders. Reliability was determined by 39 videotaped interviews rated by four judges. OFS showed excellent inter-rater reliability (intraclass correlation = 0.91) and good criterion validity by being more strongly related to other scales of occupational functioning (mid R:rmid R: = 0.39-0.47) than to measures of general distress (SCL-90-GSI) and interpersonal problems (IIP)(mid R:rmid R: = 0.26 and 0.12). OFS is a simple, reliable and clinically meaningful instrument for assessment of work ability in depressive and anxiety disorders.
目的是介绍新开发的工作能力观察者评定量表——职业功能量表（OFS）的内容及其基本心理测量特性。精神障碍会在包括职业功能在内的多个领域导致功能损害。在精神科研究中，与工作相关功能的评估常常被忽视，部分原因是缺乏可靠且有效的工具。通过将OFS与其他工作能力测量方法（SAS - 工作、工作能力指数、病假情况）以及与非工作能力相关的测量方法[人际问题清单（IIP）、症状自评量表 - 总体症状指数（SCL - 90 - GSI）]进行比较，对150名患有抑郁或焦虑障碍的患者评估了OFS的有效性。通过由四名评判员对39次录像访谈进行评分来确定信度。OFS显示出极好的评分者间信度（组内相关系数 = 0.91），并且通过与其他职业功能量表的相关性更强（中度相关系数：rmid R: = 0.39 - 0.47），而与一般痛苦量表（SCL - 90 - GSI）和人际问题量表（IIP）的相关性较弱（中度相关系数：rmid R: = 0.26和0.12），显示出良好的效标效度。OFS是一种用于评估抑郁和焦虑障碍患者工作能力的简单、可靠且具有临床意义的工具。
