Internal Family Systems (IFS):

Internal family systems (IFS) is a psychotherapy, developed in the 1980s by psychologist Richard Schwartz, that sees the mind as a family made up of distinct subpersonalities or parts taking on healthy-to-unhealthy roles. IFS therapy intervenes when life events/trauma cause people to toward extreme roles by finding “self” and bringing parts together. IFS works well for those with marginalized identities, low self-esteem, self-criticism, or shame and can treat depression, anxiety, panic and phobias, trauma, and substance use.
