Researchers developed and validated the Japanese version of the State Self-Compassion Scale (SSCS-J). This scale measures self-compassionate responses to negative events and shows reliability across sexes and construct validity.
Area of Science:
- Psychological assessment
- Cross-cultural psychology
- Clinical psychology
Background:
- The State Self-Compassion Scale (SSCS) was previously developed in the U.S. to assess self-compassionate reactions to specific negative events.
- Cross-cultural validation of psychological measures is crucial for their reliable application in diverse populations.
Purpose of the Study:
- To develop and validate the Japanese version of the State Self-Compassion Scale (SSCS-J).
- To examine the measurement invariance of the SSCS-J across sexes.
- To provide further evidence for the construct validity of the SSCS-J.
Main Methods:
- Two studies were conducted with a total of 1070 participants (Study 1: n = 596; Study 2: n = 474).
- Bifactor exploratory structural equation modeling (Bifactor ESEM) was used to analyze the factor structure of the SSCS-J.
- Measurement invariance across sexes was tested in Study 1.
- Correlations with trait self-compassion, fear of self-compassion, and negative beliefs about self-compassion were examined.
- An experimental manipulation was used in Study 2 to assess the scale's sensitivity to self-compassion induction.
Main Results:
- The bifactor ESEM analysis demonstrated an excellent fit for the SSCS-J, supporting a single global self-compassion factor and six well-defined specific factors.
- Measurement invariance of the SSCS-J across sexes was confirmed in Study 1.
- The SSCS-J scores were positively associated with trait self-compassion and negatively associated with fear of and negative beliefs about self-compassion.
- Participants instructed to practice self-compassion reported significantly higher SSCS-J scores compared to the control group in Study 2.
Conclusions:
- The factor structure of the SSCS is replicable in Japan, supporting the validity of the SSCS-J.
- The SSCS-J is a reliable and valid measure of state self-compassion in a Japanese context.
- The findings support the cross-cultural applicability and construct validity of the State Self-Compassion Scale.
