简要总结
The present study aims to compare the differential effects of a mindfulness-based intervention (MBI) and physical exercise (PE) on different stress and health variables by self-reports. A randomized controlled trial of three groups is proposed, with pretest, posttest and four follow-ups at 1, 2, 3 and 6 months that would be developed among the employees of two large multinationals.
详细描述
Work and workplace related problems are common sources of stress. Work-related stress is associated with a decrease in productivity, greater absenteeism, accidents and injuries, mental illness, greater errors, and poor performance, among others, which involve significant financial costs. Therefore, it is crucial to find coping strategies that are effective in reducing such stress. Probably, the most appropriate strategies, for their real possibilities of implementation, for their easy execution, low cost and for the empirical support they have, are mindfulness-based interventions (MBIs) and physical exercise (PE). Both types of practices have shown beneficial effects for physical health, mental health and psychological well-being in general. Different investigations have compared the implementation of MBI and PE, both combined and separately, with interesting results.
The main objective is to evaluate the interactive effects of group x time, the intragroup changes and the differences between groups, in the different moments (pretest, posttest, 1, 2, 3 and 6-months follow-up) on general health, stress, affective job satisfaction, recovery, work performance, and positive and negative affect in the three groups considered; an MBI, an aerobic PE program and an inactive control / waiting list (LE) condition will be contrasted.
The secondary objective is to evaluate the trend and linear patterns in the change trajectory in the three groups during the eight weeks of intervention on fatigue, psychological distancing, sleep, work stress, and attention.
A randomized controlled trial of three groups is proposed, with pretest, posttest and four follow-ups at 1, 2, 3 and 6 months that would be developed among the employees of two large multinationals (N ≥ 150).
The primary dependent variables considered are: 1) recovery experiences; 2) perceived stress; 3) general health; 4) affective job satisfaction; 5) individual work performance; and 6) positive and negative affects. The secondary dependent variables considered are daily states of: 1) fatigue, 2) psychological distancing, 3) quality of sleep; 4) work stress; and 5) attention.

Blinding of trial participants and care providers is not possible because of obvious differences between the interventions. However, participants will be blinded in terms of which intervention is considered the experimental one.

结局指标
主要结局
Change in Need for Recovery with six time points data.
时间窗: Baseline, Post-treatment 8 weeks from baseline, 1-month follow-up, 2-month follow-up,3-months follow-up and 6-months follow-up
The Need for Recovery (NFR) Scale consists of 9 items. It facilitates the understanding of the factors that can lead to sustainable working and employability. It is answered on a Likert-type scale from 1 to 5 (1 = Never and 5 = Always). The score was used to generate a total score ranging from 1 to 100.Our research team will carry the validation of the Spanish version of NFR.
Change in stress with six time points data.
时间窗: Baseline, Post-treatment 8 weeks from baseline, 1-month follow-up, 2-month follow-up,3-months follow-up and 6-months follow-up
A single item was used: Stress refers to a person's situation when they feel tense, restless, nervous, or anxious, or are unable to sleep at night because their mind is constantly preoccupied with work-related issues. Please indicate the extent to which you currently feel this type of stress. It has five possible responses on a Likert-type scale from 1 to 5 (being 1 nothing and 5 a lot)
Change in Positive and Negative Affect with six time points data.
时间窗: Baseline, Post-treatment 8 weeks from baseline, 1-month follow-up, 2-month follow-up,3-months follow-up and 6-months follow-up
The PANAS Scales of Positive and Negative Affect (PANAS) - Spanish version has 20 items. It is the most widely used scale of affectivity. It has two dominant dimensions, positive affect (10 items) and negative affect (10 items) It is answered on a Likert-type scale from 1 to 5 (1 = Very slightly or Not at all and 5 = Extremely). The score was used to generate a total score ranging from 20 to 100.
Change in General Health with six time points data.
时间窗: Baseline, Post-treatment 8 weeks from baseline, 1-month follow-up, 2-month follow-up,3-months follow-up and 6-months follow-up
The General Health Questionnaire (GHQ-12) consists of 12 items. It is a unidimensional measure of psychological distress. It is answered on a Likert-type scale from 1 to 4 (1 = Never and 4 = Always). The score was used to generate a total score ranging from 0 to 36.
Change in Individual Work Performance with six time points data.
时间窗: Baseline, Post-treatment 8 weeks from baseline, 1-month follow-up, 2-month follow-up,3-months follow-up and 6-months follow-up
The Individual Work Performance Questionnaire (IWPQ)-Brief Spanish version (IWPQ) has 18 items. It measures the three main dimensions of job performance: task performance, contextual performance, and counterproductive work behavior. It is answered on a Likert-type scale from 1 to 5 (1 = Never or Seldom and 5 = Always or Often). The score was used to generate a total score ranging from 18 to 90.
