Objectives. This descriptive-correlational study aims to determine the extent of socio-cognitive characteristics, perceived barriers and the factors contributing to treatment adherence among PTB patients.

Methods. A survey was administered to PTB patients registered under the Directly Observed Treatment Short Course (DOTS) program of Binan and Cabuyao, Laguna.  Records review and key informant interview were also utilized to determine adherence rates.

Results. There were 184 PTB patients who participated in the study. Knowledge on PTB and its treatment and perceived threat of PTB was high, and perceived barriers to PTB treatment is low; but the respondents were uncertain on the perceived benefits of PTB treatment adherence.  Perceived social support towards PTB treatment adherence was high, opportunity and time costs were low, and accessibility to PTB treatment services was high.  Adherence to daily medication taking was reported by 98.4% of the respondents and 78.3% of these had the intention to complete the duration of PTB treatment.  The level of knowledge on PTB and its treatment, and social support from the community, and treatment partners were the most significant predictors of PTB patients’ adherence to treatment.

Conclusion. The adherence rate of the PTB patients to their treatment was high, and the extent of knowledge on PTB and its treatment was the greatest influencing factor towards PTB patients’ adherence to treatment.
