Effect on Quality of Life of Adapted Information in Pulmonary Rehabilitation in Chronic Respiratory Disease Patients

Study Overview
=================
Brief Summary
-----------------
The purpose of the clinical study is to study the effect of health-related quality of Life of information aimed at reducing the impact of a personality trait (openness to experiences) identified as a risk of non-response to pulmonary rehabilitation in patients with chronic respiratory diseases. This study will determine if a specific information focusing on characteristics of openness to experiences personality trait will lead to better benefits than a general information.

Detailed Description
-----------------
According to the Five Factor Model, personality is made of five dimensions present in varying degrees in individuals and influencing their behavior and life experiences. Several studies showed that some personality traits, according to their level, may positively or negatively influence the quality of life. They can also have an impact on the benefits obtained at the end of one treatment. In the particular context of pulmonary rehabilitation (PR) which is one of the most efficient treatment in respiratory diseases, it has been showed that with a classical support, higher scores for openness to experiences represent a risk factor for non-response in PR on quality of life (i.e. no improvement). Several authors showed that adapted interventions (ex: simple information booklets), based on personality traits, can enhance the effectiveness of the intervention. Considering that in chronic respiratory diseases, openness to experiences when it is more marked represents a risk of not improving the quality of life following a PR program, the idea of offering information in line with the characteristics of these people (i.e., search for novelties, autonomy, broad and varied interests, etc.) seems relevant and feasible. The investigators hypothesize that the patients receiving an adapted information aimed at reducing the impact of a personality trait (openness to experiences) will better improve their quality of life in comparison with the patients receiving a neutra information. The main objective is to assess the impact of life of an adapted information during pulmonary rehabilitation on quality in patients with chronic respiratory diseases.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Adapted information arm<br>In parallel with an inpatient PR program, 4 visits will be carried out: V0 : Inclusion / V1 : Randomization / V2 : Follow-up / V3: End-stay. At V1: Adapted information to the characteristics of a greater openness to experiences will be delivered to patient. The following questionnaires will be filled : Big Five Inventory BFI-FR, St. George's Respiratory SGRQ, Dyspnea-12, Self-efficacy for managing chronic disease SEMCD-6, Brief Illness Perception B-IPQ, COPD Anxiety Revised CAF-R, Patient Health PHQ-9, Montreal Cognitive Assessment Mini-MoCA At V2: *Semi-structured individual interviews will be performed. Questions will relate to the information distributed during V1 (adapted information), allowing to assess the understanding and the appropriation of it. At V3: The following questionnaires will be filled: SGRQ,Dyspnea-12,SEMCD-6,B-IPQ,CAF-R In addition, some questions will be asked to verify the adherence to information and the potential contamination bias | Other: Adapted information arm<br>* A adapted booklet will be delivered to patients at the start of the stay. This booklet contains adapted information about the pulmonary rehabilitation targetting the characteristics of the openness to experiences personality traits<br>|
| Sham Comparator: Neutral information arm<br>In parallel with an inpatient PR program, 4 visits will be carried out: V0 : Inclusion / V1 : Randomization / V2 : Follow-up / V3: End-stay. At V1: Neutral information will be delivered to patient. The following questionnaires will be filled : Big Five Inventory BFI-FR, St. George's Respiratory SGRQ, Dyspnea-12, Self-efficacy for managing chronic disease SEMCD-6, Brief Illness Perception B-IPQ, COPD Anxiety Revised CAF-R, Patient Health PHQ-9, Montreal Cognitive Assessment Mini-MoCA At V2: *Semi-structured individual interviews will be performed. Questions will relate to the information distributed during V1 (neutral information), allowing to assess the understanding and the appropriation of it. At V3: The following questionnaires will be filled: SGRQ,Dyspnea-12,SEMCD-6,B-IPQ,CAF-R In addition, some questions will be asked to verify the adherence to information and the potential contamination bias | Other: Neutral information arm<br>* A neutral booklet will be delivered to patients at the start of the stay. This booklet contains neutral information about the pulmonary rehabilitation<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
