Interpersonal Psychotherapy is a short-term evidence-based treatment with a foundation in Attachment Theory. The premise behind IPT is that human beings are social creatures and when affected by mental health issues, they tend to withdraw from social contact and/or tend to become less effective at communicating their needs. The focus of this treatment is identifying social supports and improving interpersonal functioning.
There is evidence that IPT is effective for treating mood disorders, anxiety disorders, eating disorders within a wide age range, from adolescents to the elderly. It is also a useful technique for building the communication skills of couples that engage in a high degree of conflict (i.e. for those separating and/or those hoping to stay together).
