The Effectiveness of Psychological Interventions in Psycho-neuroendocrine-immune Network in Breast Cancer Survivors

Study Overview
=================
Brief Summary
-----------------
In this study researchers will examine an influence of three different psychological interventions in the form of mobile application on psycho-neuroendocrine-immune system among breast cancer survivors.

Detailed Description
-----------------
Background: Most studies focusing on the effects of psychological interventions on health-related outcomes have relied on self-reports. There is also growing research interest in the effects of such interventions on directly measurable biological processes associated with chronic stress. Neuroendocrine-immune system interactions are fundamental tools through which stress affects the course of cancer. The study will examine effect of three psychological interventions on most frequently studied stress related biomarkers: cortisol, HRV (heart- rate variability), CRP, relative and absolute counts of: B-lymphocytes ,T-lymphocytes, NK-cells, NK-T-like cells, monocytes; cytokine levels. Although current research suggests salutogenic changes in the immune profile of cancer patients as a result of psychological interventions, the results of individual studies are still inconsistent. To get clearer outcomes researchers decided to follow recommendations for researchers in manner that optimizes study design: to recruit very homogenous sample of cancer patients, to continue measurements in 3 and 9 months follow up, to collect data on individual´s adherence to protocol of mobile application.1,2 In addition to biomarkers, researchers will monitor changes in psychological variables. Aims of the project and main hypotheses: To test the long-term and short-term effectiveness of eHealth adaptations of three standardized mental health support programmes for cancer patients (MBCT-Ca, PP and AT) - administered through the mobile application MOÚ MindCare, in reducing psychological distress and preventing changes in the functioning of the autonomic nervous system, endocrine system and immune system that have been linked to chronic stress and are likely to have a negative impact on both mental and physical health in the long-term perspective if not managed. The investigators expect that participants in all three intervention group will show more adaptive psychological functioning, higher quality of life, lower levels of stress, depression, anxiety, fatigue, sleep disturbances and other common problems associated with breast cancer survivorship, higher HRV levels and lower cortisol levels as compared to the treatment-as-usual control group, when controlling for pre-intervention values. The investigators also expect group differences in immune system functioning, correlated with differences in other markers of stress. To compare the potentially differential effects of the three intervention programmes on biological and psychological indicators of stress and quality of life. The investigators tentatively expect programmes involving a cognitive component (MBCT-Ca and PP) to be more effective than AT, especially for psychological outcomes. To examine the extent to which the observed effects of each programme are mediated by characteristics the interventions are primarily expected to influence. The investigators expect the effect of MBCT to be primarily mediated by mindfulness, self-compassion and emotion regulation, and the effect of PP to be primarily mediated by self-compassion, gratitude and perceived hope. To evaluate the moderating roles of intervention adherence and perceived acceptability in the effectiveness of the intervention programmes. The investigators expect higher adherence and acceptability to be associated with greater improvement in the outcome variables. These data will also help identify types of individuals for whom each programme might be most and least suitable and provide information on sources of potential problems with MOÚ MindCare - or generally mHealth - intervention adherence. Methods: The research is conceptualized as a randomized control trial employing a 4 × 4 factorial design. Participants will be randomly assigned to one of the four arms: 1. MBCT-Ca (Mindfulness Based Cognitive Therapy for Cancer) 2. PP (Positive Psychology) 3. AT (Autogenic training) 4.WL (Waiting list). Participants will take the 8 week online program via mobile application. Assessment measurements will be collected in four phases. Phase 1: Assessment at the start of the programme. Phase 2: Assessment in the week after programme completion. Phase 3: Follow-up assessment 3 months after the end of programme. Phase 4: Follow-up assessment 9 months after the end of programme. Data collection will contained: collection of blood samples, single lead ECG, administration of self-report measures. Main data collection points will be synchronized with regular check-ups for each participant to minimize drop-out rates and the burden on the participants.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in heart rate variability (HRV) using ECG | HRV will be obtained from ECG measured according to a protocol involving a standardized sequence of measurements taken at rest with uncontrolled and controlled breathing. The completion of questionnaire related to rumination and impact of the cancer event before the measurement of rest ECG will serve as the priming of distress. The obtained data will be processed using the Kubios HRV Premium program- time-domain HRV parameters - RMSSD, SDNN, pNN50 and Power Spectrum density HRV parameters - LF power, HF power, and LF/HF ratio. | baseline, week 9 from baseline, month 3 post-intervention, month 9 post-intervention | 
| Change in symptoms of individual stress level using the Perceived Stress Scale | The Perceived Stress Scale (PSS) is a classic stress assessment instrument. The questions in this scale ask about feelings and thoughts during the last month. Each question has five response options ranging in value from null to four (0=never; 1=almost never; 2=sometimes; 3=fairly often; 4=very often). To find the total raw score, sum the values of the response to each question (reverse code items 4, 5, 7a and 8). Individual scores on the PSS can range from 0 to 40 with higher scores indicating higher perceived stress. | baseline, week 9 from baseline, month 3 post-intervention, month 9 post-intervention | 
| Change in depression, anxiety and stres using the Depression, Anxiety and Stress Scale | The Depression, Anxiety and Stress Scale (DASS-21) is a 21 items scale designed to measure depression, anxiety, and stress. The instrument comprises three subscales: the emotional states of depression, anxiety, and stress. Each question has four response options ranging in value from null to four (0= did not apply to me at all; 1= applied to me to some degree, or some of the time; 2= applied to me a considerable degree or a good part of time; 3= applied to me very much or most of the time). To find the total raw score, sum the values of the response to each question for each of subscale (scores will need to be multiplied by 2 to calculate the final score). The lowest possible raw score is 0 and the highest possible raw score is 42 for each subscale. A higher score represents more of the concept being measured. | baseline, week 9 from baseline, month 3 post-intervention, month 9 post-intervention |

A higher score represents more of the concept being measured. | baseline, week 9 from baseline, month 3 post-intervention, month 9 post-intervention | 
| Change in health-related quality of life using The Functional Assessment of Chronic Illness Therapy (FACIT)-Spiritual Well-Being (Sp) | The Functional Assessment of Chronic Illness Therapy - Spiritual Well-Being (FACIT)-(Sp) is composed of the FACT-General (FACT-G) and a 12-item Spiritual Well-Being scale (FACIT-Sp-12).The FACT-G (Version 4) is a 27-item compilation of general questions divided into four primary QOL subscales: Physical Well-Being (PWB; 7-items), Social/Family Well-Being (SWB; 7-items), Emotional Well-Being (EWB; 6-items), and Functional Well-Being (FWB; 7-items).Each question has five response options ranging in value from null to four (0= not at all; 1= a little bit; 2=somewhat; 3= quite a bit; 4=very much). The total FACT-G score is obtained by summing individual subscale scores (PWB + EWB + SWB + FWB). The lowest possible raw score is 0 and the highest possible raw score is 48 in Spiritual Well-Being subscales. The lowest possible raw score is 0 and the highest possible raw score is 108 in FACT-G. A higher score represents more of the concept being measured. | baseline, week 9 from baseline, month 3 post-intervention, month 9 post-intervention |
