Brief Summary

This is a pilot study consisting of mixed-methods, pre-post evaluation of a gratitude intervention (gratitude letter and visit) on palliative care patients and their caregivers.

Detailed Description

Study background and aims:

Gratitude, defined as an "other-oriented" emotion, has shown to impact significantly on many relevant dimensions for palliative care (e.g. well-being, psychological distress and the quality of relationships). Various psychological interventions focused on the enhancement of the feeling of gratitude have been developed and assessed but mostly in non-clinical populations and never taking into account the relationship dimension as an outcome.

The fact that the relational component has never been addressed in interventional studies is all the more surprising since several experimental and non-clinical studies have clearly shown an association between gratitude and feeling of social affiliation, relational commitment, satisfaction with relationships or partner reciprocal maintenance behaviours. These results appear to be very promising for palliative care since interpersonal (and particularly familial) relationships are crucial for palliative care patients: the relational sphere represents a major predictor contributing to both their meaning in life and their quality of life. We hypothesize that considering this concept in palliative care could benefit both the patients and their relatives.

Thus, the purpose of this research is to conduct a pilot study before a possible randomized controlled multicenter trial whose final aim will be to examine whether a gratitude-based intervention in a palliative care setting can increase the quality of life and the quality of the relationship of patients and their caregivers and decrease their psychological distress and burden.

The specific aims of this pilot study are:

(i) to realize a cross-cultural translation of outcome measures that are not yet available in French (ii) to establish the feasibility of the study design (iii) to investigate the appropriateness of the gratitude concept and the gratitude-based intervention in the palliative care context, and finally (iv) to explore the sensitivity to change of our selected measures in order to calculate a sample size.

Procedure and measures:

Quantitative data will be collected at baseline (T0) and post-intervention (T1) with validated questionnaires. The intervention will last for one week. Five to ten days after T1, qualitative data will be collected from semi-structured interviews with the participants and from the content of the gratitude letters to explore their representations of the gratitude concept and their perception of the intervention.

The intervention includes the following steps:

1. Patients and caregivers recruitment: The clinical team (treating physician or advanced practice nurse) at each recruitment site will identify 10 patient-caregivers dyads. A research collaborator will then be in charge of giving information and get consent

2. Data collection at T0: Before the intervention, patients and their caregivers who agreed to participate will meet the research collaborator to fill quantitative questionnaires.

3. Intervention - 1-week duration: The intervention will be proposed to both the patient and the caregiver and consists of two steps: the "gratitude letter" and the "gratitude visit". In the "gratitude letter", the participant (at least one of the patient or the caregiver) writes about his feelings of gratitude through a letter, based on a written instruction. The "gratitude visit" consists of an extension of the gratitude letter where the writer of the letter (i) either personally reads the letter to the beneficent or (ii) gives it to him and asks him to read it in his presence or later in his absence.

4. Data collection at T1: 5 to 10 days after the intervention itself, the patient and the caregiver, will meet with the research collaborator again to participate to a second quantitative assessment, similar to T0.

5. Qualitative assessment: 5 to 15 days after T1: This part is facultative. During the qualitative interviews, the following topics will be explored: their meanings of the term "gratitude"; experiences of gratitude; their experience of the intervention itself; obstacles and facilitators of the intervention; the impact of the intervention for themselves and for their relationship.

Study Groups

Gratitude intervention

The intervention will be proposed to both the patient and the caregiver and consists of two steps: the "gratitude letter" and the "gratitude visit". In the "gratitude letter", the individual writes about his feelings of gratitude through a letter, based on a written instruction. The "gratitude visit" consists of an extension of the gratitude letter where the writer of the letter (i) either personally reads the letter to the beneficent or (ii) gives it to him and asks him to read it in his presence or later in his absence.

Group Type: EXPERIMENTAL

Gratitude intervention

Intervention Type: BEHAVIORAL

The intervention will be proposed to both the patient and the caregiver and consists of two steps: the "gratitude letter" and the "gratitude visit". In the "gratitude letter", the individual writes about his feelings of gratitude through a letter, based on a written instruction. The "gratitude visit" consists of an extension of the gratitude letter where the writer of the letter (i) either personally reads the letter to the beneficent or (ii) gives it to him and asks him to read it in his presence or later in his absence.

Eligibility Criteria

Inclusion Criteria

• Age >18
• progressive disease
• reduced life expectancy
• enrolment in palliative care
• stable state for the previous 24h assessed by the physician or the nurse in charge of the patient
• informed consent signed by patient
• For each patient, the identification of a close family or friend caregiver (fulfilling the below criteria*) and who accepts to participate in the trial (by signing an informed consent)

In this research, a caregiver is defined as "a person who devotes time to help a family member or a friend affected in her/his health or autonomy. The caregiver assures, in a non-professional and regular way, a presence and a support to help her/him in his difficulties and assures her/his safety. The caregiver can be a friend, a family member or a neighbour" (Vaud canton definition). This definition will be the basis for the palliative patient to identify his caregiver.

• Age >18
• Identified as the caregiver by the palliative patient (see above)
• prior agreement of the patient for the participation of the caregiver

Exclusion Criteria

• Person completely isolated socially, no family or friend caregiver identified
• Significant cognitive or psychiatric disorders which would affect the ability to give informed consent for this research
• Severe communication problems (foreign language, deafness, etc.).

• Psychiatric and cognitive disorders which would affect the ability to give informed consent for this research based on the information reported by the clinical team in charge of the patient and the personal evaluation of the research collaborator.
• Communication problems (foreign language, deafness, etc.).

• Minimum Eligible Age: 18 Years
• Eligible Sex: ALL
• Accepts Healthy Volunteers: Yes
