Abstract
Aims: This study aimed to evaluate baseline-adjusted between-group differences in tuberculosis prevention knowledge and attitudes following structured, multicomponent health education in Indonesian primary care.
Materials & Methods: This nonrandomized, quasi-experimental, pretest–posttest control-group study was conducted at Lubuk Alung Health Center, Padang Pariaman, from November to December 2024. Forty registered patients with active tuberculosis were purposively recruited and nonrandomly allocated to intervention (n=20) and control (n=20) groups. The intervention consisted of a 15-20-minute structured education package integrating tuberculosis information with behavioral and household environmental risk-reduction messages. The control group received routine counseling. Knowledge was measured using 8 items scored from 1 to 3, and attitude was measured using 15 items scored from 1 to 5. Separate ANCOVA models were used to compare posttest scores between groups while adjusting for the corresponding pretest score.
Findings: Mean knowledge scores increased from 17.25±2.10 to 20.45±1.57 in the intervention group and from 16.80±2.24 to 19.80±1.58 in the control group. The baseline-adjusted difference was 0.40 points (95% CI -0.27 to 1.08), F(1,37)=1.47, p=0.233, partial η²=0.038. Mean attitude scores increased from 48.70±5.31 to 55.95±5.08 in the intervention group and from 45.20±4.07 to 49.20±3.75 in the control group. The baseline-adjusted attitude difference was 4.19 points (95% CI 2.23 to 6.16), F(1,37)=18.72, p<0.001, partial η²=0.336; HC3-robust inference remained significant (p=0.002).
Conclusion: Structured multicomponent health education is associated with improved posttest attitudes but not knowledge.
