An acceptance-based healthy lifestyle programme for community-dwelling patients with pneumoconiosis: A waitlist pilot randomised controlled trial.
Abstract
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. 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? 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. 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, p = 0.002) and improvement in exercise self-efficacy (β = 11.68, p = 0.007) at Week 6, and reduction in body weight (β = -1.09, p < 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. The integration of acceptance-based components into pneumoconiosis management may reduce psychological inflexibility and promote engagement in exercise.
Clinical relevance
Does a 6-week acceptance-based healthy lifestyle programme, compared with a waitlist control, reduce psychological inflexibility and improve health outcomes in community-dwelling patients with pneumoconiosis? __SNAPSHOT__ {"studyDesign":"Two-arm, prospective, multicenter, waitlist pilot randomised controlled trial","setting":"Community-dwelling setting; multicenter (specific country and institutions not reported in the supplied abstract, though contextual literature suggests Hong Kong)","sampleSize":"n=80 (intervention: 40, waitlist control: 40; 1:1 allocation ratio)","population":"Community-dwelling adults with a confirmed diagnosis of pneumoconiosis experiencing respiratory symptoms (cough, dyspnoea) and associated psychological distress; further inclusion/exclusion criteria not reported in the supplied abstract","intervention":"A 6-week acceptance-based healthy lifestyle programme consisting of four biweekly interactive group sessions integrating acceptance-based components (consistent with Acceptance and Commitment Therapy principles) into pneumoconiosis self-management","comparator":"Waitlist control (participants received the programme after the assessment period, at Week 6)","primaryOutcome":"Psychological inflexibility, assessed at baseline, Week 6, and Week 14 using a validated instrument (specific instrument not named in the supplied abstract)","followUp":"14 weeks (assessments at baseline, Week 6, and Week 14)","fundingSource":"Not reported in the supplied abstract"}
Key findings
The supplied abstract is truncated prior to reporting quantitative outcome data; therefore, no primary outcome effect sizes, confidence intervals, p-values, or NNT/NNH can be reported or calculated. The abstract indicates that 80 patients were recruited and randomly assigned in a 1:1 ratio. The sentence describing between-group results for the intervention arm is cut off ('Compared to the waitlist group, the participants in the intervention group s—'). Secondary health outcomes were assessed but their results are similarly unreported in the available text. Adverse events were not described in the supplied abstract. A generalised estimating equations (GEE) model was pre-specified as the primary analytic approach. No quantitative findings can be presented without risk of fabrication.
Practice implications
IMPORTANT LIMITATION: Only a truncated abstract was available for this summary; the results section is incomplete. It is therefore impossible to determine whether the primary outcome (psychological inflexibility) was significantly reduced, whether any secondary health outcomes (e.g., quality of life, symptom burden, physical function, anxiety, depression) were improved, or whether effect sizes are clinically meaningful. What can be inferred from the design: this was an appropriately framed pilot RCT in a clinically underserved population—pneumoconiosis patients experience progressive, irreversible lung fibrosis with no disease-modifying pharmacotherapy, making symptom management and psychological resilience high-priority targets. The waitlist design ensures all participants ultimately receive the intervention, which is ethically appropriate but limits long-term comparative follow-up. The 14-week total observation window is short for a chronic progressive disease. The multicenter design enhances potential generalisability within the study population. Until the complete results are available, no practice-informing conclusions should be drawn from this study. Clinicians should seek the full-text publication directly. __LIMITATIONS__ 1. Abstract truncation: quantitative results are unavailable for critical appraisal, making assessment of efficacy, safety, and clinical significance impossible at this time. 2. Pilot RCT: explicitly designated as a pilot study; likely underpowered to detect definitive treatment effects and not designed to establish efficacy. 3. Small sample size (n=80): limits precision of effect estimates and subgroup analyses. 4. Waitlist design: precludes blinding of participants to group assignment, introducing performance and detection bias; the waitlist group's awareness of delayed access may affect psychological outcomes. 5. Short follow-up (14 weeks): insufficient to assess durability of effects in a chronic, progressive, incurable disease. 6. Surrogate/patient-reported primary outcome: psychological inflexibility is a process variable rather than a clinical endpoint (e.g., hospitalisation, mortality, lung function decline); its relationship to hard outcomes in pneumoconiosis has not been established. 7. Trained research assistants conducted assessments, but blinding of assessors is not confirmed in the abstract. 8. Generalisability: community-dwelling patients may not represent those with more severe disease or functional limitation; specific ethnicity, disease stage, and comorbidity data not reported. 9. Funding source not reported; potential conflicts of interest cannot be assessed. __BOTTOM_LINE_CATEGORY__ low_certainty __BOTTOM_LINE__ This multicenter waitlist pilot RCT evaluated a 6-week acceptance-based healthy lifestyle programme targeting psychological inflexibility in community-dwelling pneumoconiosis patients, but the abstract was truncated before quantitative results were reported, precluding any assessment of efficacy or clinical significance. Clinicians should access the full published text before drawing any clinical conclusions. This study addresses a genuine unmet need in an irreversibly progressive occupational lung disease, and if adequately powered confirmatory trials demonstrate meaningful and durable benefit, the approach could inform psychological and behavioural components of pneumoconiosis rehabilitation programmes.
