The purpose of this study was to clarify the relationship between two self-identities of teachers who coach athletic club activities (their sport coach identity and their teacher identity) and their degree of mental depression and to clarify the factors that formed the identity associated with depression. The participant were 157 middle school and high school teachers who coached athletic club activities (male: 128, female: 29), who completed the Brief Scale of Social Support for Workers (BSSSW; Mori and Miura, 2006), the scale support for family, the Sports Coach (teacher) Identity Scale (Yahiro and Hagiwara, 2019), the teacher identity scale (Matsui and Shibata, 2008), PHQ-9 (Muramatsu et al., 2007; Muramatsu and Kamijima, 2009). The reliability and validity of every scale were confirmed by Cronbach’s alpha and confirmatory factor analysis. The result of this research indicated that the teacher self-identity demonstrated a relationship with depression. In addition, multiple regression analysis showed that support from family demonstrated a relationship with teacher identity and the BSSSW didn’t demonstrate a relationship with teacher identity. This study finds that receiving support from family forms the teacher identity and forming a teacher identity could prevent depressive tendencies.
