The current study aimed to achieve two purposes. The first was to develop a shortened version of the Gratitude-Expression Skills Scale while maintaining a level of measurement accuracy comparable to the original. The second was to investigate the relationship between gratitude-expression skills and trust in teams. A web-based questionnaire survey was conducted using a panel from a survey company, targeting individuals employed in the teams. We successfully developed a 10-item shortened version of the Gratitude-Expression Skills Scale using confirmatory factor analysis and item response theory. Additionally, hierarchical multiple regression analyses supported the hypothesis that individuals who utilize gratitude-expression skills towards their team members exhibit higher levels of trust in their teams. On the other hand, the hypothesis that trust in teams would increase with utilizing gratitude expression skills in teams with high task interdependence and ability diversity was not supported. The positive effect of gratitude expression skills on trust within teams is generally robust regardless of team characteristics. However, further research is needed for teams with high task interdependence and ability diversity.
