Abstract

INTRODUCTION: Adherence to TB treatment is an important issue for TB control, with key health consequences. Identification of the factors associated with that adherence is also important. The objective of this study was to identify factors associated with adherence to tuberculosis treatment, using the health belief model (HBM). METHODOLOGY: Overall 297 TB patients were recruited to the study using the census method. All patients completed a 40-question survey form anonymously. The questionnaire was developed based on the Health Belief Model. Data collection was carried out through interviews and questionnaires, as well as observing medical records and medical cards to be used in medical performance checklists. RESULTS: The participants comprised 159 men and 138 women with an average age of 56.8 years (range 19-72 years). The results showed that the variables of perceived threat, benefits, barriers, and self-efficacy accounted for 42% of the variance in therapeutic adherence. The strongest predictor of adherence was found to be self-efficacy. CONCLUSION: HBM appears to be a suitable model in predicting therapeutic adherence in TB patients. Our results emphasize the centrality of self-efficacy in treatment adherence, that health educators should consider when developing programs to motivate patients to adhere to treatment.

  • In TB care, the Health Belief Model proposes that adherence is shaped by patients' perceived susceptibility to TB-related complications, perceived severity of the disease, perceived benefits of completing treatment, perceived barriers to taking medication regularly, cues to action, and self-efficacy in managing the regimen.

    “In the specific case of TB care, the Health Belief Model proposes that adherence is shaped by patients’ perceived susceptibility to TB-related complications, perceived severity of the disease, perceived benefits of completing treatment, perceived barriers to taking medication regularly (such as side effects, stigma, or transport costs), cues to action, and self-efficacy in managing the regimen [29”

    The Results and Discussion link TB treatment adherence to perceived threat (including seriousness and susceptibility), benefits, barriers, and self-efficacy. Our copy does not identify cues to action as an adherence factor, and it does not substantiate transport costs as a specific barrier; its Discussion instead identifies the belief that TB drugs are harmful.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
