The Brief Illness Perception Questionnaire (B-IPQ) has never been used for assessing the perception of stroke patients yet in Indonesia. The validity and reliability tests of Indonesian version of B-IPQ instrument are needed to ensure this instrument is valid, reliable, and justifiable. The objective of this research was to determine the validity and reliability of Indonesian version of B-IPQ instrument for stroke patients at RSUD Soedarso Pontianak. This research was a non-experimental study using cross-sectional approach. The B-IPQ was translated using multiple translators method. Data of 30 stroke patients were taken using purposive sampling method. Respondents involved including 3 stroke inpatients and 27 stroke outpatients. Validity test was assessed using Pearson correlation (correlation score ≥ 0,3) and reliability test was assessed using Internal consistency technique (Cronbach alpha coefficient ≥ 0,7). The results showed that the correlation score in each item of instrument was > 0.3 and the Cronbach alpha coefficient of this instrument was 0.771 (> 0.7). It is concluded that Indonesian version of B-IPQ instrument is valid and reliable to assess the perception of illness for stroke patients at RSUD Soedarso Pontianak.
