Notes that while relational-cultural theory (RCT) was initially developed to understand women's psychological experience, it is increasingly being used to gain a better understanding of all human experience, including men's experience. Special attention is being paid to examining the importance of difference, particularly difference informed by imbalances of power and privilege. RCT is the foundation for a growing body of research on depression, trauma, eating disorders, substance abuse, chronic illness, mother-daughter relationships, and lesbian relationships, as well as issues of racism, sexism, heterosexism, classism and a multitude of other psychological and social problems. Topics discussed here include a relational paradigm of development, RCT therapy and practice, and a relational-cultural reframing of resilience.
