The purpose of this investigation was to identify the critical tasks encountered by correctional officers (COs) on the job and to conduct a comprehensive assessment and characterization of the physical demands of these tasks. These are the first steps in developing a fitness screening test for COs in compliance with recent legislation. The most important, physically demanding, and frequently occurring tasks were identified using Delphi methodology, focus groups, and questionnaire responses from 190 experienced front-line COs. These tasks were structured into emergency response scenarios for which a physical and physiological characterization was conducted to verify their relative physical demands analysis. Oxygen consumption and the forces exerted by COs were quantified while they were responding and then controlling and restraining inmates. The female COs used less force than the male COs did to control and restrain the same inmates (body control = 46 vs. 60 kg, wrist hold = 32 vs. 49 kg, and arm retraction = 37 vs. 47 kg) and did not exert their maximal strength during their control and restraint activities. The mean oxygen consumption of the female and male COs while performing the on-the-job tasks was similar (39.5 vs. 38.5 mL.kg-1.min-1). We concluded that the essential components of a fitness screening protocol for CO applicants are cell search, expeditious response, body control, arm restraint, inmate relocation, and an assessment of aerobic fitness. The criterion performance standards for completing these tasks in a circuit were set at the job performance level of safe and efficient female COs.
本研究旨在确定狱警在工作中遇到的关键任务,并对这些任务的身体需求进行全面评估和描述。这是根据最新法规为狱警开发体能筛选测试的第一步。通过 Delphi 方法、焦点小组和 190 名经验丰富的一线狱警的问卷调查回复,确定了最重要、最具体力要求且经常发生的任务。这些任务被构建成应急响应场景,对其进行了身体和生理特征描述,以验证其相对体力需求分析。在响应、控制和约束囚犯的过程中,量化了狱警的耗氧量和施加的力。在控制和约束相同囚犯时,女性狱警所施加的力小于男性狱警(身体控制=46 对 60 千克,手腕握力=32 对 49 千克,手臂回缩=37 对 47 千克),并且在控制和约束活动中并未发挥出最大力量。女性和男性狱警执行在职任务时的平均耗氧量相似(39.5 对 38.5 毫升/千克/分钟)。我们得出结论,狱警申请人体能筛选方案的基本组成部分是牢房搜索、快速响应、身体控制、手臂约束、囚犯转移和有氧适能评估。完成这些任务的标准表现标准是设定在安全且高效的女性狱警的工作绩效水平上。
