Using self-determination theory to predict self-management and HRQoL in moderate-to-severe COPD

Objective: Chronic Obstructive Pulmonary Disease (COPD) is a long-term condition that detrimentally affects health-related quality of life (HRQoL), with self-management proposed as an effective treatment. Using self-determination theory (SDT), this research explored psychological need satisfaction, frustration, and behavioural regulation to explain indicators self-management.Design Main Outcome Measures: Cross-sectional, questionnaire-based methods in people on pulmonary rehabilitation waiting-list. 72 participants completed SDT, HRQoL, knowledge questionnaires. Path analyses investigated the ability SDT concepts predict HRQoL.Results: Chi-square tests found no significant differences (χ2(13, N=72) = 16.7, p > 0.05) between just – over-identified models, multiple measures suggested acceptable fit data. Relatedness frustration positively predicted controlled autonomy relatedness satisfaction autonomous regulation. The associations other needs different types were not statistically significant. Both strongly HRQoL (35% variance explained) (22% explained).Conclusion: can more self-determined regulation, knowledge, provide framework for researchers healthcare professionals develop future health interventions COPD. Greater needed understand basic contexts.
