Research in the U.S. developed and validated the State Self-Compassion Scale (SSCS), which measures self-compassionate reactions toward a specific negative event. The current study is aimed at developing the Japanese version of the State Self-Compassion Scale (SSCS-J) and extending previous findings in the U.S. by showing measurement invariance across sexes and demonstrating the construct validity of this scale. Across two studies (n = 596 in Study 1, n = 474 in Study 2), the bifactor exploratory structural equation modeling representation of the SSCS-J showed excellent fit in which a single global factor (i.e., self-compassion) and most of the specific factors (six subscales) were well defined. Study 1 further provided evidence for the measurement invariance across sexes. The SSCS-J was related with higher trait self-compassion and lower fear of and negative beliefs about self-compassion. In Study 2, participants who were instructed to be self-compassionate reported higher scores in the SSCS-J relative to those in the control condition. These results attest to the replicability of the factor structure of the SSCS in Japan and provide further evidence for the construct validity of this scale.

Neff et al. (2021, Mindfulness) による状態セルフ・コンパッション尺度 (State Self-Compassion Scale) の日本語版です。Studies 1 and 2で、日本語版状態セルフ・コンパッション尺度 (SSCS-J) の因子構造を確認し、他の変数との関連から妥当性を検討しました。Study 2ではNeff et al. (2021) で用いられた状態的にセルフ・コンパッションを高める実験操作 (Self-compassionate mindstate induction) を用いて、セルフコンパッション群では統制群に比べて、状態セルフ・コンパッションが高いことを示しました。SSCS-Jの項目や日本語版Self-compassionate mindstate inductionの教示は論文の電子付録に掲載しております。
