An experiment conducted at the corporate offices of a manufacturing firm investigated the effects of daily relaxation breaks on five self-reported measures of health, performance, and well-being. For 12 weeks, 126 volunteers filled out daily records and reported bi-weekly for additional measurements. After four weeks of baseline monitoring, they were divided randomly into three groups: Group A was taught a technique for producing the relaxation response; Group B was instructed to sit quiety; Group C received no instructions. Groups A and B were asked to take two 15-minute relaxation breaks daily. After an eight-week experimental period, the greatest mean improvements on every index occurred in Group A; the least improvements occurred in Group C; Group B was intermediate. Differences between the mean changes in Groups A vs C reached statistical significance (p < 0.05) on four of the five indices: Symptoms, Illness Days, Performance, and Sociability-Satisfaction. Improvements on the Happiness-Unhappiness Index were not significantly different among the three groups. The relationship between amount of change and rate of practicing the relaxation response was different for the different indices. While less than three practice periods per week produced little change on any index, two daily sessions appeared to be more practice than was necessary for many individuals to achieve positive changes. Somatic symptoms and performance responded with less practice of the relaxation response than did behavioral symptoms and measures of well-being. (Am. J. Public Health 67:946-953,1977)
在一家制造企业的公司办公室进行的一项实验,调查了每日放松休息对健康、绩效和幸福感的五项自我报告指标的影响。在12周的时间里,126名志愿者填写每日记录,并每两周汇报一次以进行额外测量。在四周的基线监测之后,他们被随机分为三组:A组学习了一种产生放松反应的技巧;B组被指示安静地坐着;C组未接受任何指示。A组和B组被要求每天进行两次15分钟的放松休息。在为期八周的实验期之后,A组在各项指标上的平均改善最大;C组的改善最小;B组处于中间水平。在症状、患病天数、绩效和社交满意度这五项指标中的四项上,A组与C组的平均变化差异达到了统计学显著性水平(p < 0.05)。在幸福-不幸福指数上,三组之间的改善没有显著差异。不同指标的变化量与放松反应练习频率之间的关系各不相同。虽然每周练习次数少于三次时,各项指标几乎没有变化,但对于许多人来说,每天进行两次练习似乎比实现积极变化所需的练习更多。与行为症状和幸福感指标相比,躯体症状和绩效对放松反应练习的反应较小。(《美国公共卫生杂志》67:946 - 953,1977年)
