Impact of Tuberculosis Prevention Therapy Policies on Quality of Life Among Patients in Surakarta, Indonesia

Tuberculosis (TB) is a chronic infectious disease that affects millions of people worldwide. This article aims to examine the impact of TB prevention therapy policies on social support, medication adherence, personal stigma, and quality of life among TB patients in Surakarta, Indonesia. This is a quasi-experimental study using a pretest–posttest design involving 88 TB patients who visited the primary health centre in Mojosongo Village, Surakarta, Indonesia, from March to October 2023. This study employed a purposive sampling approach, specifically targeting TB patients attending primary health centres. Participants completed the Tuberculosis-Related Stigma Scale, Morisky Medication Adherence Questionnaire, Family Support Questionnaire, and World Health Organization Quality of Life–BREF (WHOQOL–BREF) questionnaire before and after the intervention. The study design included one-group pretest–posttest. Data analysis was performed using SPSS 22.0, applying independent samples t-test for mean comparisons and Pearson correlation coefficient to examine relationships between scale scores. The results showed a significant average difference between pretest and posttest scores on stigma, social support, medication adherence, and quality of life (QOL) for the experimental group (p = 0.0001), as well as stigma for the control group (p = 0.0001). There were also significant mean differences between the experimental group and the control group on stigma, medication adherence, and QOL (p = 0.0001). In addition, Pearson correlation showed a significant relationship between TB prevention therapy policies on stigma, medication adherence, and QOL (p = 0.0001). The findings of this study show that TB preventive therapy policies have a positive effect on social support, medication adherence, personal stigma, and quality of life for TB patients.
