Development and validation of non-adherence to pulmonary rehabilitation questionnaire: a clinical tool for patients with chronic obstructive pulmonary diseases.

Abstract

OBJECTIVE Non-adherence is a serious issue among the participants in pulmonary rehabilitation program (PRP). Till date, no clinical tool is available to screen participants who will show poor adherence towards PRP. This study aimed to develop and validate a tool called "Adherence to Pulmonary Rehabilitation Questionnaire (APRQ)", a self-administered questionnaire to screen the risk of non-adherence to PRP among the patients with chronic obstructive pulmonary disease. APRQ comprises of 6 main constructs such as disease management behaviour, perceived treatment benefits, emotional factors, perceived severity of disease, barriers towards treatment and coping attitude. MATERIALS AND METHODS This was a preliminary validity study carried out in the physiotherapy department and respiratory clinic in an university teaching hospital. A total of 109 patients with average age of 58.8 ± 1 year participated in the study. The inclusion criteria for subjects were: patients diagnosed with chronic obstructive pulmonary diseases (COPD) (Stage II and III). Exclusion criteria include those COPD patients with mental problems and disabled patients. The tool was developed based on thematic analysis and in-depth interview with focus group and literature search on the factors that lead to non-adherence among the PRP's participants. Principal component analysis was carried out to examine the construct validity and content validity of APRQ. RESULTS A total of 20 items were created under 6 constructs. However, 2 items (smoking and hospital admission) were eliminated due to poor correlations. Thus, the final version of APRQ was developed and validated with 18 items. Reliability was measured using internal consistency and achieved Cronbach's Alpha of 0.762. CONCLUSIONS The findings from this preliminary study supports that APRQ may be a valid and reliable tool to screen adherence towards PRP among chronic lung disease patients.
