Objective:
This study aimed to determine whether the ISQ can be used to assess immune status in daily clinical practice in Indonesia by translating the questionnaire into Bahasa and analyzing its validity and reliability.
Methods:
The ISQ was translated both forward and backward by a professional translator fluent in both English and Bahasa. In this study, a cross-sectional study design was used, and Pearson's correlation test and Cronbach's Alpha calculation were used to perform the validity and reliability test. The questionnaire is valid if the computed R-value exceeds the R table value. Furthermore, it will also be considered reliable if Cronbach's Alpha value is greater than 0.60.
Result:
The computed R-value for each item is greater than the R table value (0.361), implying that all items in the questionnaire are valid. The Cronbach's Alpha value of 0.706 demonstrates that the questionnaire is reliable.
Conclusion:
The ISQ is a reliable and valid questionnaire, which can be used in Bahasa to assess patients' perspectives about their immune status.
