Does attachment change serve as a theory-specific mediator of depression reduction in interpersonal psychotherapy versus cognitive behavioral therapy?

Key Points

• The research aims to investigate whether attachment change mediates depression reduction in two types of therapy: interpersonal psychotherapy (IPT) and cognitive behavioral therapy (CBT).
• Comparison of the effects of IPT and CBT on attachment security and depression
• Measurement of attachment security early in treatment
• Assessing depression levels before and after therapy
• Increased attachment security is linked to depression reduction across both therapies
• The change in attachment security appears to be an important process in therapy outcomes
• Attachment change is more theory-common than specific to IPT
