In a 6-month longitudinal randomized field experiment, we examined how using height-adjustable sit-stand desks could have beneficial, adverse, and spiraling effects on people's musculoskeletal and psychovegetative complaints, and on positive (vitality and vigilance) and negative psychological symptoms, namely, stressor uncontrollability (i.e., perceived uncontrollability of workload), psychological tension, and mental tiredness. A total of 127 employees in various, mostly sedentary, occupations were randomly assigned to either the intervention or the control group. Variables were assessed monthly for 6 months on a self-reported basis. Bayesian structural equation modeling showed that the intervention produced large inhibiting between-subjects effects for musculoskeletal problems in the neck, back, and shoulders (β ranged between -.26 and -.21). Within-subject analyses revealed that the intervention produced large inhibiting effect sizes for intensity (g = 3.06) and prevalence of musculoskeletal (g = 1.19) and psychovegetative complaints (g between 0.76 and 1.57). For negative psychological symptoms (i.e., psychological tension and mental tiredness), participants in the intervention group showed a steeper decrease than participants in the control group (g between 2.34 and 3.74). For positive indicators (i.e., vitality and vigilance), the intervention produced large promoting effects for participants in the intervention group compared with participants in the control group (g between 0.70 and 1.65). There was no change in stressor uncontrollability between the two groups. Finally, findings suggest that sit-stand desks can be effective in improving occupational health by weakening a downward-spiraling effect.

有益,不利和螺旋式的健康促进效应:来自于坐立式办公桌工作的纵向随机对照试验的证据。
在一个为期6个月的纵向随机野外实验中,我们研究了使用可调节高度的坐立式办公桌如何对人们的肌肉骨骼和心理植物性疾病以及积极的(活力和警惕性)和消极的心理症状产生有利,不利和螺旋效应,即压力源的不可控制性(即,工作量的不可控制性),心理紧张和精神疲劳。总共将127种不同职业(主要是久坐的职业)的雇员随机分配到干预组或对照组。根据自我报告,每月评估变量,为期6个月。贝叶斯结构方程模型表明,该干预对颈部,背部和肩膀的肌肉骨骼问题产生了较大的受试者间抑制作用(β介于-.26和-.21之间)。受试者内部分析显示,该干预措施对强度(g = 3.06),肌肉骨骼疾病(g = 1.19)和精神营养不良(g在0.76和1.57之间)的患病率产生了较大的抑制作用。对于负面的心理症状(即心理紧张和精神疲倦),干预组的参与者比对照组的参与者表现出更大的下降趋势(g在2.34和3.74之间)。对于积极指标(即活力和警惕性),与对照组相比,干预对干预组参与者产生了巨大的促进作用(g在0.70至1.65之间)。两组之间的应激源失控性没有变化。最后,研究结果表明,坐立式办公桌可以通过减弱向下呼吸作用来有效改善职业健康。(PsycINFO数据库记录(c)2019 APA,保留所有权利)。
