Refinement of the Occupational Fatigue Exhaustion Recovery (OFER) scale.
The responses of 510 nurses to the OFER scale, two of whose scales contained additional items, were examined with CFA and regression analyses.
Analyses of the expanded pool of items identified three subscales of 5 items each for the renamed OFER15 scale. The subscales have high internal reliability (>.84), face, construct and discriminant validity. SEM analysis confirmed the role of recovery in mediating the relationship between acute and chronic fatigue measured with the OFER15 scale.
The OFER15 measure is a parsimonious scale with robust psychometric properties whose subscales distinguish well between acute fatigue states and chronic fatigue traits. The intershift recovery subscale is unique among published fatigue scales. The OFER15 is suggested as a valuable new instrument for the researchers in the work-related fatigue area, and also as screening instrument in Primary Care.
完善职业疲劳耗竭恢复（OFER）量表。
对510名护士对OFER量表的回答进行了验证性因素分析（CFA）和回归分析，其中两份量表包含额外项目。
对扩展项目池的分析确定了重新命名的OFER15量表的三个分量表，每个分量表有5个项目。这些分量表具有较高的内部信度（>.84）、表面效度、结构效度和区分效度。结构方程模型（SEM）分析证实了恢复在调节OFER15量表所测量的急性疲劳和慢性疲劳之间关系中的作用。
OFER15量表是一个简洁的量表，具有强大的心理测量学特性，其分量表能很好地区分急性疲劳状态和慢性疲劳特征。轮班间恢复分量表在已发表的疲劳量表中是独一无二的。建议OFER15量表作为工作相关疲劳领域研究人员的一种有价值的新工具，也作为初级保健中的筛查工具。
