In this study, we developed and validated the Non-Self Perspective Scale (NSPS). Non-self-perspective refers to the idea that ‘Self’ is a phenomenological experience that changes consistently depending on the prevailing conditions and it means a self-view based on Buddhist wisdom. In Study 1, NSPS was developed, and in Study 2, the reliability and validity of NSPS were verified. NSPS was developed through item selection, expert’s item evaluation, first preliminary test, cognitive interview, second preliminary test and main test. Finally, a 15-item single factor NSPS was developed. In main test, test-retest reliability was .72, which was an appropriate level. NSPS was significantly correlated with self-view-related variables such as independent/interdependent self-construal, metapersonal self and narcissistic personality disorder. NSPS was significantly correlated with practical aspects of non-self, such as mindfulness, zhongyong, compassionate love, nature relatedness and lack of tolerance for uncertainty. NSPS was significantly correlated with mental health such as depression, anxiety, subjective well-being and psychological well-being. On the other hand, NSPS showed incremental validity for the mental health indicators even after controlling for adaptive and independent self-views such as internal locus of control and self-esteem. Based on these results, discussions were conducted. Finally, implications and directions of use of NSPS were introduced and further studies were suggested.
