Determinants of transmission prevention behavior among TB patients in Surabaya

Who

The study involved 144 tuberculosis (TB) patients receiving care at three primary healthcare centers. Participants were selected using simple random sampling. No further demographic characteristics (e.g., age, sex) were specified.

What

The study examined determinants influencing TB transmission prevention behavior, focusing on patient knowledge, supportive behavior, and medication adherence.
Results showed that most participants had good knowledge, supportive behavior, medication adherence, and TB transmission prevention behavior. Multiple linear regression analysis demonstrated that all three factors significantly influenced TB transmission prevention behavior (p < 0.05). Each one-point increase in:

• Knowledge increased prevention behavior by 0.667 points

• Supportive behavior increased prevention behavior by 0.370 points

• Medication adherence increased prevention behavior by 0.720 points

The authors concluded that improving patient education, community support, and adherence to treatment is essential for effective TB control.

When

Not specified.

Where

The study was conducted in Surabaya, Indonesia, across three primary healthcare centers.

Why

The research aimed to identify key factors influencing TB transmission prevention in order to help prevent and reduce TB cases, addressing a critical gap in patient-level behavioral determinants of TB control.

How

An observational cross-sectional study design was used. Data were collected through questionnaires and individual interviews. The questionnaire assessed four domains: TB knowledge, supportive behavior, medication adherence, and transmission prevention behavior. Instrument reliability was tested using Cronbach’s alpha, showing acceptable to high reliability (α = 0.611–0.879). Variables were categorized into predefined levels (poor, moderate, good) to aid interpretation. Multiple linear regression analysis (α < 0.05) was applied to evaluate the effects of independent variables on TB transmission prevention behavior.
