<p>This paper reports the development and validation of a state self-esteem scale based on the Two-Item Self-Esteem Scale (TISE). Participants completed the state self-esteem scale in hypothetical scenarios. The criterion-related validity was confirmed owing to the significantly higher TISE score in a positive situation than in a negative situation for both achievement and affiliation scenarios. The concurrent validity was confirmed by the positive correlations between the TISE and a modified state Rosenberg self-esteem scale. The internal consistency of the TISE was also confirmed. Results showed that the TISE was a useful tool in assessing state self-esteem.</p>
