Development of the "Belief of Affective Perspective-Taking Ability Scale"

This study aimed to develop the Belief of Affective Perspective-Taking Ability Scale (BAPTAS). The belief of affective perspective-taking ability is defined as the tendency of individuals to believe people are generally capable of taking others' perspectives and imagining others' emotions, and we developed 17 items for BAPTAS. The participants in the study comprised 151 university students, who answered the BAPTAS, Experience of Receiving Empathy Scale (ERES), perspective-taking tendency, Interpersonal Trust Scale (ITS), and UCLA loneliness scale in Japanese (ULS-J). Thus, 13 items were constructed, and the scores of BAPTAS showed a normal distribution (M = 4.52, SD = 0.97). BAPTAS is positively related to ERES, a perspective-taking tendency and ITS, and it is negatively related to ULS-J. The relations between BAPTAS and other scales correspond to our previous expectations. We discussed both the potential contribution of BAPTAS to perspective-taking and empathy research and the need to examine its validity experimentally. Our hypothesis was supported, and the validity and reliability of BAPTAS were confirmed.
