Abstract

In terms of tuberculosis cases, Indonesia is second only to India. Successful outcomes in the treatment of tuberculosis depend on patient compliance with their prescribed medication. The MARS (Medication Adherence Report Scale) questionnaire can be used to assess medication adherence in tuberculosis patients. The researchers in this study set out to see if the MARS questionnaire was sufficiently valid and reliable to be used with TB patients in Indonesia. Descriptive quantitative analysis using a cross-sectional design was employed for this study. The MARS survey was the instrument used for this study. Sixty tuberculosis patients from the Lamongan District Health Center met the inclusion criteria and made up the sample size of 70. Sampling with the help of a planned strategy. Apply the Pearson Product Moment correlation test to the questionnaire to see if it is reliable. The Cronbach alpha coefficient was used to determine the questionnaire's reliability in this study. According to the data, the r count correlation value was higher than the r table value of 0.2542. The Cronbach Alpha Coefficient obtained from the reliability analysis was 0.486. The results of the validity and reliability tests indicated that the Indonesian translation of the MARS questionnaire was a valid and reliable tool for gauging the degree to which tuberculosis (TB) patients took their prescribed medications as directed. Adherence should be measured with a reliable questionnaire or instrument to ensure accurate results

Abstract

Tuberculosis (TB) is one of the infectious diseases that needs to be watched out for in Indonesia. TB affects the quality of life of patients, such as physical, social, emotional, functional and spiritual factors. Valid instrument measurements are needed to determine the quality of life of TB patients. FACIT-TB is a questionnaire used as a measurement of quality of life in TB patients. The purpose of this study was to determine the validity and reliability of the Indonesian version of the FACIT-TB questionnaire as a valid questionnaire. This study used a quantitative method with a sample of 110 respondents at the Lamongan Regional Health Center. The results obtained were tested using the Pearson correlation test to determine its validity while for reliability it was seen with the Cronbach alpha value. The results of the validity test were declared valid with the requirement that the calculated r value > r table. The results of all FACIT-TB questionnaire questions were declared valid. The results of the reliability test used the Cronbach alpha value with the entire domain value > 0.6. Therefore, the Indonesian version of the FACIT-TB questionnaire is a valid and reliable measurement of quality of life for TB patients. Quality of life must be measured with a valid questionnaire or instrument to obtain accurate results.
