Psychological and Neurobiological Impact of a Retreat Based on Mindfulness and Compassion for Stress Reduction. (Retreat)

The study is aimed at comparing the differential effects of two widely used standardized meditation programs: Mindfulness-Based Stress Reduction (MBSR) and Compassion Cultivation Training (CCT) delivered in a retreat format with a cross-over design in a general population sample of healthy adults.

Study Overview

• Status: Completed
• Conditions: Stress; Compassion; Psychological Distress; Emotion Regulation; Psychophysiologic Reaction; Mindfulness
• Intervention / Treatment: Behavioral: Mindfulness-Based Stress Reduction; Behavioral: Compassion Cultivation Training

Detailed Description

The main objective of the study is to evaluate the effects of two mindfulness-based intensive interventions: Mindfulness-Based Stress Reduction (MBSR) training or Compassion Cultivation Training (CCT), on psychological, physiological and epigenetic changes in a population of health volunteer adults. During a 7-day retreat participants will be randomised to two study arms: group 1 and 2, beginning either with a 3-day MBSR training or a 3-day CCT training. On the 4th day they will cross-over to the opposite intervention.

To address this goal, the effects will be measured by self-report questionnaires belonging to different domains (mindfulness, compassion, well-being, psychological distress, and psychological functioning), psychophysiological measures (EEG resting state, Diurnal cortisol slope, EKG and respiration patterns), epigenetic changes (DNA methylation biomarkers) and an objective stress task (Arithmetic Stress Test). Psychobiological outcome measures will be collected from both groups on day 1 (pre-intervention), on day 4 (post intervention and before beginning of the second intervention). The third assessment will be conducted on day 7 for both groups (post-second intervention). A 6-month follow-up assessment will be carried in both groups only for psychological questionnaires.

Data analysis will include change scores in psychological outcome measures as well as DNA methylation (by EPIC arrays) and gene expression (RNA-seq) measures.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Group 1 (MBSR + CCT); Group 1 will begin the retreat with a 3-day MBSR intervention. On day 4 of the retreat, they will crossover and begin a 3-day CCT intervention.	Behavioral: Mindfulness-Based Stress Reduction; The MBSR is an 8-week standardized program (Kabat-Zinn,1990). During the retreat, participants will receive intensive training during 3 days (from 4:00pm to 9pm the first day and from 7 am to 10 pm including breaks, the second and third days), including focused attention on the breath, open monitoring of awareness in body-scanning, prosocial meditation (i.e. loving kindness and compassion) and gentle yoga. Training is delivered by certified instructors by the University of Massachusetts Centre for Mindfulness (https://www.umassmed.edu/cfm/).; Other Names: MBSR; Behavioral: Compassion Cultivation Training; The CCT is an 8-week standardized program (Jinpa, 2010; Jazaieri et al. 2013, 2014) consisting of daily formal and informal practices. Training will be conducted during 3 days of the retreat (same schedule as the MBSR training). The CCT consists of six sequential steps: 1) Settling the mind and learn how to focus it; 2) Loving kindness and compassion for a loved one practice; 3) Loving kindness and compassion for oneself practice; 4) compassion toward others, embracing shared common humanity and developing appreciation of others; 5) compassion toward others including all beings; and 6) active compassion practices (Tonglen) which involve explicit evocation of the altruistic wish to do something about others' suffering.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Epigenetic changes	Blood samples: 20 ml collected in the standard tubes used in clinical haematology that contain EDTA as an anticoagulant. From this biological material, DNA and RNA will be extracted according to the standard molecular biology procedures, in order to subsequently measure DNA methylation (by EPIC arrays) and gene expression (RNA-seq), respectively.	Pre-intervention (T1: Day 1 in the 7-day program), mid-intervention (T2: Day 4 in the 7-day program), and post-intervention (T3: Day 7 in the 7-day program)
Change in Psychological distress	Depression Anxiety Stress Scales (DASS-21), (Lovibond and Lovibond, 1995). The DASS-21 is a 21-item scale containing 3 subscales (Anxiety, Depression and Stress), with 7 items for each subscale. Participants are asked to rate each item using 4-point Likert scale (0=Not applicable to me; 3=Very applicable to me). Higher scores correspond to higher levels of severity of anxiety, stress, and depression.	Pre-intervention (T1: Day 1 in the 7-day program), mid-intervention (T2: Day 4 in the 7-day program), post-intervention (T3: Day 7 in the 7-day program), and 3-month follow-up (T4)
Change in Stress Reactivity	Mathematical Stress Test: a standardized laboratory stress induction procedure (Kirshbaum et al., 1992). Individuals are asked to repeatedly subtract a given 2-digit number from a 4-digit number. Time is limited to 3 minutes and participants are told that this is a mental speed task and their performance will be evaluated. Stress levels will be evaluated with an affective adjective checklist (PANAS scales).	Pre-intervention (T1: Day 1 in the 7-day program), mid-intervention (T2: Day 4 in the 7-day program), and post-intervention (T3: Day 7 in the 7-day program)
Change in Resting State Activity	EEG resting state (alternating open and closed eyes). EEG resting state will be recorded with four 64-channel EEG devices with laptop and eego EEG recording software. The sampling rate will be 1000 Hz and the reference to be used will be 7Z of the equidistant layout. The interventions will significantly change the EEG spectral profile of the resting state brain activity. We expect changes in the balance between Alpha (8-14 Hz) and Theta (4-8 Hz) frequency bands.	Pre-intervention (T1: Day 1 in the 7-day program), mid-intervention (T2: Day 4 in the 7-day program), and post-intervention (T3: Day 7 in the 7-day program)
Change in Cortisol activity	Cortisol samples 1.5 - 2.0 ml will be collected in Salivette® cortisol saliva sample collection tubes (Sarstedt, Germany) that contain sterile cotton plugs for sample absorption. From this biological material, levels of the principal stress corticosteroid, the hormone cortisol, will be assessed in order to subsequently measure the Diurnal Cortisol Slope and cortisol levels at awakening and bedtime. Using saliva collection tubes, levels of the principal stress corticosteroid, the hormone cortisol, will be assessed in order to subsequently measure the Diurnal Cortisol Slope and cortisol levels at awakening and bedtime at three different moments of the retreat.	Pre-intervention (T1: Day 1 in the 7-day program), mid-intervention (T2: Day 4 in the 7-day program), and post-intervention (T3: Day 7 in the 7-day program
