In recent years, researchers have developed effective research methods using ICT, such as the experience sampling method (ESM). The main purpose of this workshop was to make a proposal about how we could make use of ESM in clinical settings targeting people with difficulties in emotion regulation. Prior to the workshop, participants experienced ESM procedures by monitoring their daily emotion regulation experiences themselves . During the workshop, participants first learned basic knowledge about ESM and emotion regulation. After that, participants were divided into two groups, and discussed approaches to make use of ESM in clinical settings. As a result, the two groups came up with ideas regarding the use of ESM in clinical settings. Both groups mentioned the importance of data feedback and data-based reflection/discussion with a professional therapist. These ideas have implications for developing a more sophisticated approach to make use of ESM in interventions targeting difficulties in emotion regulation.
