  The purpose of the present research was to develop a scale to measure the skill of expressing gratitude. In Study 1, items for the scale were selected from an analysis of the results from 2 questionnaires completed by university students, and the reliability, content validity, and criterion-related validity of the Gratitude-Expression Skills Scale (GSS) were confirmed. In Study 2, a longitudinal study with university students demonstrated the test-retest reliability and predictive validity of the scale. Study 3 used a role-playing method. The participants were 60 university students (23 men, 37 women). The results demonstrated the criterion-related validity of the scale. These results provide empirical evidence for the validity of the Gratitude-Expression Skills Scale. The scale is different from existing conventional scales assessing the gratitude trait.
