Improving physical activity, sedentary behaviour and sleep in COPD: Perspectives of people with COPD and experts via a Delphi approach


Abstract

Background: Little is known about how to achieve enduring improvements in physical activity (PA), sedentary behaviour (SB) and sleep for people with chronic obstructive pulmonary disease (COPD). This study aimed to: 1. identify what people with COPD from South Australia and the Netherlands, and experts from COPD- and non-COPD-specific backgrounds considered as important to improve behaviours; and 2. identify areas of dissonance between these different participant groups.

Methods: A four-round Delphi study was conducted, analysed separately for each group. Free-text responses (Round 1) were collated into items within themes and rated for importance on a 9-point Likert scale (Rounds 2-3). Items meeting a priori criteria from each group were retained for rating by all groups in Round 4. Items and themes achieving a median Likert score of ≥7 and an interquartile range of ≤2 across all groups at Round 4 were judged important. Analysis of variance with Tukey’s post-hoc tested for statistical differences between groups for importance ratings.

Results: 73 participants consented to participate in this study, of which 62 (85%) completed Round 4. In Round 4, 81 items (PA n=54; SB n=24; sleep n=3) and 18 themes (PA n=9; SB n=7; sleep n=2) were considered as important across all groups concerning: 1. disease management, 2. targeting behavioural factors, and less commonly 3. adapting the social/physical environments. There were few areas of dissonance between groups.

Conclusion: Important to our Delphi participants is a multifactorial approach to improve PA, SB and sleep. Recognising and addressing important factors may provide a basis for developing interventions to improve these behaviours long-term.

Notes for potential reviewers

  • Volunteering is not a guarantee that you will be asked to review. There are many reasons: reviewers must be qualified, there should be no conflicts of interest, a minimum of two reviewers have already accepted an invitation, etc.
  • This is NOT OPEN peer review. The review is single-blind, and all recommendations are sent privately to the Academic Editor handling the manuscript. That said, if the manuscript is accepted for publication then the reviewer reports can be optionally signed and made public (see below).
  • What happens after volunteering? It may be a few days before you receive an invitation to review with further instructions. You will need to accept the invitation to then become an official referee for the manuscript. If you do not receive an invitation it is for one of many possible reasons as noted above.

  • PeerJ does not judge submissions based on subjective measures such as novelty, impact or degree of advance. Effectively, reviewers are asked to comment on whether or not the submission is scientifically and technically sound and therefore deserves to join the scientific literature. Our Peer Review criteria can be found on the "Editorial Criteria" page - reviewers are specifically asked to comment on 3 broad areas: "Basic Reporting", "Experimental Design" and "Validity of the Findings".
  • Reviewers are expected to comment in a timely, professional, and constructive manner.
  • Until the article is published, reviewers must regard all information relating to the submission as strictly confidential.
  • When submitting a review, reviewers are given the option to "sign" their review (i.e. to associate their name with their comments). Otherwise, all review comments remain anonymous.
  • Each time a decision is made by the Academic Editor, each reviewer will receive a copy of the Decision Letter (which will include the comments of all reviewers).
  • If the article is accepted, then the authors are given the option to reproduce the reviewer reports, and their full revision history, alongside their finally published article. In those instances, the comments of the reviewers will be made public (although reviewers' names will never be revealed unless the reviewer opted to sign their review, as noted above).
