This study examined the content and construct validity, internal consistency reliability, and test-retest of the Indonesian version of the Self-Efficacy of Sleep Hygiene Inventory-Revised (SESHI-R) instrument. This quantitative study was conducted with psychometric tests using a cross-sectional design. The cultural translation and adaptation were conducted through the stages of forward translation, synthesis, backward translation, expert review, pilot testing, and validity and reliability tests. The content validity was measured using Aiken’s V. The construct validity was measured using Pearson Product Moment and factor analysis. The internal consistency reliability was measured using Cronbach’s alpha, and the test-retest used paired t-test. The content validity test showed an Aiken’s value of 0.75 to 1. The construct validity test proved that all items were valid. The factor analysis gave 18 valid items (factor loading >0.5) with 6 factors formed (Eigen value >1). The internal consistency reliability test showed a Cronbach’s alpha value of 0.894 (>0.7). The test-retest had a value of 0.747. This study showed the Indonesian version of SESHI-R has good content validity, construct validity, internal consistency reliability, and acceptable test-retest. Therefore, it can be used to assess the self-efficacy of sleep hygiene behavior among adolescents from 15 to 19 years old in Indonesia.
