Effects of a HAPA-based multicomponent intervention to improve self-management precursors of older adults with tuberculosis: A community-based randomised controlled trial

Objective To evaluate the effectiveness of a multicomponent intervention based on the Health Action Process Approach (HAPA) model to improve the self-management precursors of older adults with tuberculosis (TB). Methods A cluster-randomised controlled trial was conducted. Older adults with TB in the intervention communities received HAPA-based multicomponent interventions at the beginning of treatment and in the first and sixth months after treatment initiation, and those in the control communities received health education alone. Self-management precursors were measured at baseline and 1 week after each intervention. Results Among 262 randomized patients, 244 (93%) completed the trial. Compared with the control group, self-management precursor scores for the intervention group increased significantly over time (β group*time = 2.92, p group*time = 0.35, p group*time = 0.72, p group*time = 1.85, p Conclusion Compared with single health education, the HAPA-based multicomponent interventions significantly improved the self-management precursor of older adults with TB. Practice implications This HAPA-based multicomponent intervention strategy may be a promising self-management mode for the routine health care of TB patients.
