An acceptance-based healthy lifestyle programme for community-dwelling patients with pneumoconiosis: A waitlist pilot randomised controlled trial.
The acceptance-based healthy lifestyle program may reduce psychological inflexibility and improve exercise self-efficacy in patients with pneumoconiosis, but the clinical significance of these findings remains uncertain.

This study evaluated a 6-week acceptance-based healthy lifestyle program in community-dwelling patients with pneumoconiosis. The program aimed to reduce psychological inflexibility and improve health outcomes. Significant reductions in psychological inflexibility and body weight were observed, along with improvements in exercise self-efficacy.
Abstract
<h4>Background</h4>Respiratory symptoms such as cough and shortness of breath are prevalent among patients with pneumoconiosis. These symptoms reduce their engagement in daily activities and induce psychological distress.<h4>Research question</h4>Did a 6-week acceptance-based healthy lifestyle programme reduce psychological inflexibility (primary outcome) and enhance the health outcomes among community-dwelling patients with pneumoconiosis?<h4>Study design and methods</h4>A two-arm, prospective, multicenter, waitlist pilot randomised controlled trial was conducted. Patients with pneumoconiosis were randomly assigned to either an intervention group or waitlist group at a 1:1 ratio, with intervention group receiving the programme first. The intervention consisted of four biweekly interactive sessions on integrating acceptance-based components into pneumoconiosis management. Psychological inflexibility and health outcomes were assessed at baseline, Week 6, and Week 14 by trained research assistants. A generalized estimating equations model was used to examine the effects of the intervention effect between groups.<h4>Results</h4>Eighty patients were recruited and randomly assigned to the two groups. Compared to the waitlist group, the participants in the intervention group showed significant reduction in psychological inflexibility (β = -5.83, <i>p</i> = 0.002) and improvement in exercise self-efficacy (β = 11.68, <i>p</i> = 0.007) at Week 6, and reduction in body weight (β = -1.09, <i>p</i> < 0.001) at Week 14. No significant differences were observed for other outcomes. Moderate effect size was noted on the outcomes of psychological inflexibility and exercise self-efficacy at Week 6.<h4>Conclusion</h4>The integration of acceptance-based components into pneumoconiosis management may reduce psychological inflexibility and promote engagement in exercise.
Background
This paper addresses the impact of psychological factors on health outcomes in patients with pneumoconiosis, a condition characterized by respiratory symptoms that can lead to reduced daily activity and psychological distress. Previous research has indicated that psychological inflexibility may hinder engagement in healthy behaviors. This study aims to evaluate whether an acceptance-based lifestyle program can improve psychological inflexibility and related health outcomes in this population.
Methods
A two-arm, prospective, multicenter, waitlist pilot randomized controlled trial was conducted with 80 patients diagnosed with pneumoconiosis. Participants were randomly assigned to an intervention group or a waitlist group at a 1:1 ratio. The intervention consisted of four biweekly interactive sessions focusing on acceptance-based strategies for pneumoconiosis management. Primary outcomes included psychological inflexibility and exercise self-efficacy, assessed at baseline, Week 6, and Week 14 using a generalized estimating equations model.
Results
At Week 6, the intervention group showed a significant reduction in psychological inflexibility (β = -5.83, p = 0.002) and an improvement in exercise self-efficacy (β = 11.68, p = 0.007). At Week 14, there was a significant reduction in body weight (β = -1.09, p < 0.001). Moderate effect sizes were noted for psychological inflexibility and exercise self-efficacy at Week 6, while no significant differences were observed for other outcomes.
Interpretation
The findings suggest that the acceptance-based program may have a positive impact on psychological inflexibility and exercise self-efficacy in patients with pneumoconiosis, although the effect sizes are moderate and may not be clinically meaningful. The study's limitations, including a small sample size and short follow-up duration, restrict the ability to draw firm conclusions. Further research is needed to confirm these findings and explore long-term effects.
