To explore the effects of community-based self-management intervention on depression, anxiety, and quality of life in high-risk populations with chronic obstructive pulmonary disease(COPD), providing scientific evidence for the formulation of community-based COPD prevention and intervention policies.

Data on sociodemographic characteristics, lifestyle, health status, and lung function were collected from 464 participants through 8 community-based self-management sessions for COPD conducted in Suzhou. Anxiety and depression were assessed using the Generalized Anxiety Disorder-7(GAD-7) scale and the Patient Health Questionnaire-9 (PHQ-9). Quality of life was assessed using the EQ-5D-3L scale (including the EQ-VAS).

The results from the PHQ-9 and GAD-7 scales indicated that, after the intervention,the proportion of participants in the mild depression (anxiety) group and moderate or severe depression (anxiety) group significantly decreased, while the proportion of participants in the normal group increased significantly (P<0.05). A significant change was also observed in the PHQ-9 scale for the group with FEV1/FVC≥70% (P=0.018). In terms of quality of life,significant differences were found in the distribution of self-care, pain/discomfort, and anxiety/depression dimensions between pre- and post-intervention in both the overall population and the FEV1/FVC≥70% group (P<0.05). Except for the FEV1/FVC<70% group in EQ-VAS analysis, significant improvements were observed in the EQ-5D-3L utility index and EQ-VAS scores in all groups (P<0.001).

Community self-management interventions can improve the psychological health and quality of life of high-risk COPD populations, with more pronounced effects in the FEV1/FVC≥70% group. This study provides support for community-based COPD intervention strategies in Suzhou.
