SF-36 was self-administered to a sample of 382 pulmonary tuberculosis patients receiving self-administered or directly observed types of treatment, in baseline, initial, or continuous phase of treatment. After data collection, data was cleaned, coded, and statistically analyzed using SPSS version 21.0. Results. The results of the current study highlighted a significant impact on several domains of HRQoL of pulmonary TB patients. Highest HRQoL scores had been observed for the domain of physical functioning (60.03, ±25.779) whereas lowest HRQoL scores were observed for the domain of general health (34.97, ±14.286) perceptions of TB patients followed by bodily pain (43.40, ±24.594).
