Effect of a participatory organizational-level occupational health intervention on job satisfaction, exhaustion and sleep disturbances: results of a cluster randomized controlled trial

Abstract

BackgroundWe examined whether the implementation of a participatory organizational-level intervention aiming to improve the working environment with a focus on the core task at work, increased job satisfaction and reduced exhaustion and sleep disturbances among pre-school employees.MethodsThe study sample consisted of 41 intervention group pre-schools with 423 employees and 30 control group pre-schools with 241 employees. The intervention lasted 25 months and consisted of seminars, workshops, and workplace specific intervention activities that were developed by focusing on the core task at work. We analyzed within-group changes in the three outcome variables from baseline to follow-up with t-tests for paired samples, separately for intervention and control group. Between-group differences in changes in the three outcome variables were analyzed using a mixed model with a repeated statement to account for the clustering effect of workplaces.ResultsWithin-group analyses showed that exhaustion decreased statistically significantly in both the intervention and the control group. There were no statistically significantly changes in job satisfaction and sleep disturbances. Between-group analyses showed that there was no statistically significant difference between the two groups for changes in any of the outcome variables, neither in the unadjusted or in the adjusted analyses.ConclusionsWe found no evidence that participating in an organizational-level occupational health intervention aiming to improve the working environment with a focus on the core task at work has an effect on pre-school employees’ job satisfaction, exhaustion and sleep disturbances.Trial registration ISRCTN16271504, November 15, 2016.

Sleep, Health and Wellness at Work: A Scoping Review

“…Experience has shown that the screening of sleeping disorders and intervention to determine poor sleep quality can be incorporated into current health surveillance activities without a significant increase in medical costs or lost of medical time, and result in a substantial improvement in the quality of health care [ 94 , 130 ]. A number of health promotion programs targeted at sleepiness and fatigue prevention have been implemented [ 131 , 132 , 133 , 134 , 135 ] and proved to be effective; other programs, however, have had negative results [ 136 , 137 ]. In many studies both the internal and external validity of findings have been limited and the range of factors investigated has been insufficient.…”

Effect of a participatory organizational workplace intervention on workplace social capital: post-hoc results from a cluster randomized controlled trial

“…The original aim of this trial was to study whether the intervention had an impact on employees’ well-being and sickness absence. Results on these primary endpoints are published elsewhere [10, 11]. Change in WSC was not a defined endpoint of the trial.…”

A study of unreasonable illegitimate tasks, administrative tasks, and sickness presenteeism amongst Norwegian physicians: an everyday struggle?

“…As illegitimate tasks have been shown to act as a job stressor it is important to investigate how they affect physicians’ health and well-being [ 4 , 7 , 20 ]. Previous research has shown that illegitimate tasks are negatively related to job satisfaction [ 4 , 6 ] and positively related to counterproductive behaviour [ 2 ] and stress reactions among employees [ 21 ].…”
