Emotional Regulation in Patients With Implanted Automatic Defibrillator
Efficacy of Mindfulness Training on the Quality of Life of Patients With Implantable Automatic Defibrillator
The general objective of the study was to evaluate the impact of two emotional regulation programs, one standardized and face-to-face (MBSR: Mindfulness Based Stress Reduction) and, another, implemented through a mobile phone application (REM_Volver a casa; ERBM_Back home: Emotional Regulation Based on Mindfulness), on the quality of life, the state emotional and psychological and biological variables associated with stress, in a sample of patients with ICD (implantable cardioverter defibrillator).
The working hypotheses were that after training in emotional regulation, patients with ICD would have better quality of life, lower symptoms of anxiety, depression and hostility, and lower incidence of ventricular arrhythmias than patients in the control group, as well as that there would be no differences between the two tools used for training.

Detailed Description
The recruitment process of the participants was carried out by telephone, by the medical staff of the arrhythmia's section, who informed the patients the characteristics and objectives of the study.
The sample size was estimated considering an alpha risk of 0.05 and a beta risk of 0.2, in a bilateral contrast, to detect a difference equal to or greater than 10 units in the Quality of life variable. A standard deviation of 20 points and a 20% loss rate were assumed. The estimated n was 237 patients, to distribute in three branches of 79 patients each.
Before beginning the intervention, participants were informed about the research, and were offered the opportunity to ask questions in order to clarify any doubts about it. Next, they were given a Participant Data Collection Notebook. The Notebook included the information on the investigation and the Informed Consent, to be completed and signed; the request for demographic data (age, gender, educational level, etc.); and, the four questionnaires used to assess the psychological variables of study: SF-36 (quality of life), HADS (anxiety and depression), STAXI (hostility) and FFMQ (Mindfulness) For the descriptive analysis, the number of subjects and the corresponding percentage was used in the qualitative variables. In the quantitative variables the mean and standard deviation were used when the variables adjusted to the normal distribution; otherwise, the median and interquartile range (first and third quartile) were used. The normality test used was the Shapiro-Wilk.
In the hypothesis contrast of the pre-post values, of the variables with distribution adjusted to normal, the Student´s t statistic was used for paired data; For the variables whose distribution did not conform to normal, the Wilcoxon Test was chosen.
For the contrast of inter-group hypothesis (independent samples with distribution not adjusted to normal), the Mann Whitney test was used.
For the statistical analysis of data, the SPSS program, version 20, was used.

|
Experimental: MBSR group
Enforcement of the standardized program Mindfulness-Based Stress Reduction
|
Mindfulness training through an adaptation of the standardized MBSR program.
This program was conducted in person and in a group, with a maximum of 25 participants per group and a total duration of 8 weeks.
The training was carried out in 8 sessions, one each week, with a duration of 2 h each session.
|
Experimental: App group.
Enforcement of the emotional regulation program based on mindfulness (ERM) through the mobile phone application REM volver a casa
|
The intervention was carried out through the computer application for mobile phone "REM volver a casa".
This application has been developed to carry out training in the emotional regulation program based on mindfulness, autonomously.
The application is designed to carry out the program in 8 weeks.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Health Related Quality of Life
Time Frame: In order to assess the change at the Quality of life variable, was measured just before starting the mindfulness training program and, eight weeks later, after finishing it.
|
The questionnaire (SF-36: Short Form) uses a Likert scale of 3 or 5 points, with a range of scores from 0 to 100, average of 50 and standard deviation 10.

Secondary Outcome Measures

Measure Description |
Time Frame |

Anxiety and Depression
Time Frame: In order to assess the change at the anxiety and depression variables, were measured just before starting the mindfulness training program and, eight weeks later, after finishing it.
|
HADS: Hospital Anxiety and Depression Scale.
This scale assess the presence of anxiety or depression.
It consists of two sub-scales, of 7 items each, are scored on a Likert scale of 4 points.
The cut-off points used for the two scales were: 0 to 7 = no clinical significance; from 8 to 10 = doubtful; from 11 to 14 = moderate; from 15 to 21 = severe.

STAXI: State-Trait Anger Expression Inventory.
Questionnaire used to evaluate the expression of hostility, in terms of personality trait and regarding the circumstantial state at the time of measurement.
The scores are represented in standardized T scores: mean of 50 points and a standard deviation of 10 points.
