Clinical Trial Summary

The present study aims to compare the differential effects of mindfulness meditation (MBI) and physical exercise (PE) on different stress and health variables (self-report means and IgA and cortisol levels). A randomized controlled trial of three groups is proposed, with pretest, posttest and three follow-ups at 1, 3 and 6 months that would be developed among the Guardia Civil (Spanish military police) office staff.

Description:

Recovery from fatigue and daily work stress involves mentally disconnecting from work. To achieve this disconnection (or psychological detachment), research has shown that engaging in a variety of interesting and motivating activities for individuals after the workday allows them to achieve this disconnected state of mind and, consequently, facilitates recovery from work. Previous research has shown that two of the most effective recovery activities are physical exercise (PE) and mindfulness meditation (MBI), although the results on the differential effects of the two are not conclusive (Karabinski et al, 2021; Steed et al., 2021; Wendsche et al., 2021).

Thus, the present study aims to compare the differential effects of MBI and PE on different stress and health variables (self-report means and IgA and cortisol levels). A randomized controlled trial of three groups is proposed, with pretest, midtest, posttest and three follow-ups at 1, 3 and 6 months that would be developed among the Guardia Civil (Spanish military police) office staff (N ≥ 150). An MBI, an aerobic PE program and an inactive control / waiting list (LE) condition will be contrasted.

The dependent variables considered are: 1) recovery experiences; 2) perceived stress; 3) general health; 4) job satisfaction; 5) work performance; 6) positive and negative affect; 7) daily states of fatigue, stress, psychological distancing, mindfulness, and sleep; 8) IgA levels in saliva; 9) cortisol levels in saliva.

The intervention program is structured for two months, during which the two intervention groups will carry out their recovery strategy (MBI or PE), starting and increasing the practice 5 minutes every two weeks. The control group will continue as usual.

The investigators believe that this study is a quasi-pioneering initiative because of its theme, uses a robust methodology, and will have an important scientific-technical impact. The importance of the topic addressed in terms of health and business productivity is associated with important contributions in terms of knowledge transfer to companies and society in general.

Intervention

Behavioral:
• Mindfulness-based intervention
An mindfulness instructor will conduct meditations lasting 15 to 30 minutes. The first day of each week the intervention will be given in streaming and the rest of the days the participants will have audio files designed ad hoc with the practice of the week so they can do it individually at home.
• Physical exercise
An aerobic and fitness trainer will conduct aerobic exercise lasting 15 to 30 minutes. The first day of each week the intervention will be given in streaming and the rest of the days the participants will have video files designed ad hoc with the practice of the week so they can do it individually at home.The intensity of the chosen exercise will be moderate, maintaining between 120-140 beats per minute.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Salivary Immunoglobulin A (SIgA)	Biological measures. Salivary IgA levels as a biomarker of mucosal inmunity. Salivary IgA levels as a biomarker of mucosal inmunity	Baseline 1 week before treatment, Pre-treatment the week the interventions begin, Mid-treatment 5 weeks from baseline, Post-treatment 9 weeks from baseline, 1-month follow-up
Primary	Change in Salivary cortisol with five points data	Biological measures. Salivary cortisol levels as a biomarker of stress	Baseline 1 week before treatment, Pre-treatment the week the interventions begin, Mid-treatment 5 weeks from baseline, Post-treatment 9 weeks from baseline, 1-month follow-up
Primary	Change in General Health with six time points data.	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.	Baseline 1 week before treatment, Mid-treatment 5 weeks from baseline, Post-treatment 9 weeks from baseline, 1-month follow-up, 3-months follow-up, and 6-months follow-up
Primary	Change in stress with six time points data.	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)	Baseline 1 week before treatment, Mid-treatment 5 weeks from baseline, Post-treatment 9 weeks from baseline, 1-month follow-up, 3-months follow-up, and 6-months follow-up
Primary	Change in Affective Job Satisfaction with six time points data.	The Brief Index of Affective Job Satisfaction (BIAJS)-Spanish version (BIAJS) consists of 7 items. It is an overall measure of affective job satisfaction. It measures satisfaction in five facets: promotion, co-workers, work itself, supervision and salary. It is answered on a Likert-type scale from 1 to 5 (1 = Strongly disagree and 5 = Strongly agree).; The score was used to generate a total score ranging from 7 to 35.
