Brief Summary

The goal of this pilot randomized controlled trial is to evaluate the feasibility, acceptability, and preliminary effects of a theory-based self-management digital intervention (Respir'air BPCO) designed to promote physical activity in patients with Chronic Obstructive Pulmonary Disease (COPD) after completion of a pulmonary rehabilitation program. The main question it aims to answer is: Is the Respir'air BPCO intervention (mobile app) feasible, acceptable, and preliminarily effective in increasing physical activity, enhancing self-management, improving motivation, and quality of life, while reducing dyspnea severity, exacerbations, and hospitalizations, compared with no additional intervention? Researchers will compare an experimental group (receiving the Respir'air BPCO intervention + usual care) to a control group (no additional intervention, only usual care) Participants will: Be assigned either to the control group, receiving no additional intervention beyond usual care (traditional pulmonologist follow-up), or to the experimental group, receiving access to the Respir'air BPCO mobile app in addition to usual care.

• Complete baseline assessments immediately after finishing their in-person pulmonary rehabilitation program.
• Complete follow-up assessments at 3 months and 6 months after the start of the intervention

Outcome Measures

Primary Outcomes (10)

• Feasibility - Time required to complete recruitment

  T0 - End of face-to-face PR program (Researchers expect to need 3 months to recruit 50 participants.)

• Feasibility - The amount of missing data in the completed questionnaires

  T0: Within 72 hours after completion of the face-to-face PR program T1: 3 months after the start of the intervention (±1 week) T2: 6 months after the start of the intervention (±1 week)

• Feasibility - Potential refinements after the completion of the pilot study

  A digital logbook for researchers' use, to record any observations or comments (patients and/or researchers perspectives) regarding the intervention design, content and/or usage, with the aim of informing potential refinements after the completion of the pilot study

  From the start of the intervention to study completion, assessed for up to 9 months.

• Feasibility - Number of technical problems auto reported by the patient

  T1: 3 months after the start of the intervention (±1 week) T2: 6 months after the start of the intervention (±1 week)

• Feasibility - Intervention fidelity

  Exposure rate to all content available within the mobile application

  T1: 3 months after the start of the intervention (±1 week) T2: 6 months after the start of the intervention (±1 week)

• Acceptability - Consent and retention rates

  Consent rate: proportion of eligible participants who sign the informed consent form Retention rate: proportion of enrolled participants who remain in the study until the final assessment point

  T -1: 1 week before completion of the face-to-face PR program (±72 hours)

• Acceptability - Acceptance rate of the allocated group

  Acceptance rate will be assessed using administrative study records. It will be defined as the proportion of enrolled participants who agree to participate in the group to which they were allocated (control or intervention) immediately after randomization.

  T -1: 1 week before completion of the face-to-face PR program (±72 hours)

• Acceptability - Rate of participants successfully recruited

  T0: Within 72 hours after completion of the face-to-face PR program

• Acceptability - Intervention acceptance

  Daily App Login Status

  T1: 3 months after the start of the intervention (±1 week) T2: 6 months after the start of the intervention (±1 week)

• Acceptability - Intervention acceptance

  French-adapted version of the Treatment Acceptance and Preference (TAP) questionnaire.Responses are scored on a five-point Likert scale ranging from 0 ("not at all") to 4 ("extremely"), with higher scores reflecting greater acceptance.

  T1: 3 months after the start of the intervention (±1 week) T2: 6 months after the start of the intervention (±1 week)

Secondary Outcomes (7)

• Preliminary effectiveness measures - Main variable: number of daily steps

  T0: Within 72 hours after completion of the face-to-face PR program T1: 3 months after the start of the intervention (±1 week) T2: 6 months after the start of the intervention (±1 week)

• Preliminary effectiveness measures - secondary variable: Self-management

  T0: Within 72 hours after completion of the face-to-face PR program T1: 3 months after the start of the intervention (±1 week) T2: 6 months after the start of the intervention (±1 week)

• Preliminary effectiveness measures - secondary variable: Motivational regulation of physical activity

  T0: Within 72 hours after completion of the face-to-face PR program T1: 3 months after the start of the intervention (±1 week) T2: 6 months after the start of the intervention (±1 week)

• Preliminary effectiveness measures - secondary variable: Health-related quality of life

  T0: Within 72 hours after completion of the face-to-face PR program T1: 3 months after the start of the intervention (±1 week) T2: 6 months after the start of the intervention (±1 week)

• Preliminary effectiveness measures - secondary variable: severity of dyspnea

  T0: Within 72 hours after completion of the face-to-face PR program T1: 3 months after the start of the intervention (±1 week) T2: 6 months after the start of the intervention (±1 week)

Study Arms (2)

Usual Care

NO INTERVENTION

Traditional pulmonologist follow-up, along with physiotherapy sessions

Respir'air BPCO

EXPERIMENTAL

Self-management digital intervention (Respir'air BPCO)

Behavioral: Respir'air BPCO

Interventions

Respir'air BPCO BEHAVIORAL

Self-management digital intervention (Respir'air BPCO) grounded in theory (Self-Care Theory of Chronic Illness, Self-Determination Theory of Human Motivation, and the Behavior Change Techniques taxonomy). The mobile application includes educational resources (text, video, images), examples of physical activities (walking, etc), environmental data (air quality), a personal activity log (daily steps), reminders and motivational messages.
