The Two-Item Self-Esteem Scale (TISE) is a well-established short scale for assessing state and trait self-esteem. This study explored the test-retest reliability of the TISE-State and TISE-Trait with a sample of 135 Japanese university students at two time points (2 weeks apart). Participants completed the TISE-Trait and the Rosenberg's Self-Esteem Scale for assessing trait self-esteem. Subsequently, we assessed their state self-esteem for academic and interpersonal hypothetical events with both the TISE-State and a modified state version of the Rosenberg's Self-Esteem Scale. The test-retest reliability of the TISE-Trait (r = .77) and the TISE-State (academic: r = .83, interpersonal: r = .71) was confirmed. The same results were shown for the state and trait version of Rosenberg's Self-Esteem Scale. The study findings suggest that the TISE could be a reliable short scale for assessing both state and trait self-esteem.
