[目的]评价辽河油田基层科研人员的职业紧张水平、特征和影响因素,为制订干预措施提供科学依据。[方法]采用职业紧张量表(OSI-R)对辽河油田的基层科研人员122人进行测试,然后用统计学方法对测试结果进行比较分析。[结果]调查对象个体紧张反应在参比人群中处于中等水平;不同岗位组在职业任务和个体紧张反应问卷总分的差异具有统计学意义(P﹤0.05);岗位类型和紧张的职业任务是职业紧张的危险因素,个体应对资源为职业紧张的保护因素。[结论]辽河油田基层科研人员的职业紧张水平较高,职业紧张具有岗位特征,可通过减轻职业任务和增加应对资源来进行职业紧张管理。 [Objective] To evaluate the occupational stress level, characteristics and influencing factors of grass-roots researchers in Liaohe Oilfield and provide scientific basis for formulating intervention measures. [Methods] With OSI-R, 122 grassroots researchers in Liaohe Oilfield were tested, and then the results of the test were compared by statistical methods. [Results] The individual’s response to stress was moderate in the reference population. There were significant differences in the total score of occupational task and individual stress response questionnaire between different job groups (P <0.05). Job types and stressful job tasks were Risk factors of occupational stress, individual resources to deal with occupational stress protection factors.
