Although stress is a common experience in everyday life, a clear understanding of how often an individual experiences and reports stress is lacking. Notably, there is little information regarding factors that may influence how frequently stress is reported, including which stress dimension is measured (i.e., stressors-did an event happen, subjective stress-how stressed do you feel, conditional stress-how stressful a stressor was) and the temporal features of that assessment (i.e., time of day, day of study, weekday vs. weekend day). The purpose of the present study was to conduct a coordinated analysis of five independent ecological momentary assessment studies utilizing varied stress reporting dimensions and temporal features. Results indicated that, within days, stress was reported at different frequencies depending on the stress dimension. Stressors were reported on 15-32% of momentary reports made within a day; across days, the frequency ranged from 42 to 76% of days. Depending on the cutoff, subjective stress was reported more frequently ranging about 8-56% of all moments within days, and 40-90% of days. Likewise, conditional stress ranged from just 3% of moments to 22%, and 11-69% of days. For the temporal features, stress was reported more frequently on weekdays (compared to weekend days) and on days earlier in the study (relative to days later in the study); time of day was inconsistently related to stress reports. In sum, stress report frequency depends in part on how stress is assessed. As such, researchers may wish to measure stress in multiple ways and, in the case of subjective and conditional stress with multiple operational definitions, to thoroughly characterize the frequency of stress reporting.
尽管压力是日常生活中常见的体验,但人们对个体经历和报告压力的频率缺乏清晰的认识。值得注意的是,关于可能影响压力报告频率的因素的信息很少,包括测量的压力维度(即压力源-事件是否发生、主观压力-你感到多大压力、条件性压力-压力源的压力有多大)和评估的时间特征(即一天中的时间、研究日、工作日与周末)。本研究的目的是对五项独立的生态瞬间评估研究进行协调分析,这些研究利用了不同的压力报告维度和时间特征。结果表明,在一天内,根据压力维度,压力的报告频率不同。在一天内进行的瞬间报告中,压力源的报告频率为 15-32%;在多天内,频率范围为 42-76%的天数。根据截止值的不同,主观压力的报告频率更高,在一天内的所有瞬间中约为 8-56%,在多天内约为 40-90%。同样,条件性压力的范围从仅 3%的瞬间到 22%,以及 11-69%的天数。就时间特征而言,压力在工作日(相对于周末)和研究初期(相对于研究后期)的报告频率更高;一天中的时间与压力报告不一致。总之,压力报告的频率部分取决于压力的评估方式。因此,研究人员可能希望以多种方式测量压力,并在主观和条件性压力具有多个操作定义的情况下,充分描述压力报告的频率。
