This study focuses on the inferiority complex experienced in the course of life of middle-aged women in their 40s and 50s phenomenologically, and explored some coping methods in the application of art therapy to deal with inferiority complex experienced by middle-aged women. With 4 subjects in their 40s and 6 subjects in their 50s, 12 sessions of art therapy, along with pre- and post-interviews, were carried out from January 2018 to January 2019. The collected data were analyzed using the Colaizzi six-step data analysis method, which resulted in categorization by negation and positive response. The research was divided into 50 subjects, and these subjects were then further divided into six subjects, ultimately creating basically two categories of denial and positivity. These themes were derived from 105 semantic compositions made available by 401 meaningful statements from participants. In a negative response, relationships were able to bind topics with “the age at which everything would be troublesome,” work with a “lack of courage”, and love with “the prejudice on the body.” In a positive response, three thems were present: “age to start anything,” “courage to change,” and “thank you for a very special gift.” This study shows the significance in doing phenomenological research on middle-aged women’s methods of coping with inferiority complex by applying art therapy and investigating the changing process. Especially, the results are expected to help middle-aged women to cope with inferiority complex in a positive manner, to pursue superiority, to increase social interest, and to contribute to communities.
