Why Does Psychotherapy Work and for Whom? Hormonal Answers

Area of Science:

• Psychoneuroendocrinology
• Clinical Psychology
• Psychotherapy Research

Background:

• Psychotherapy effectiveness research traditionally relies on self-report measures.
• The biopsychosocial model provides a framework for integrating biological factors into mental health understanding.
• Hormonal influences on psychotherapy outcomes remain underexplored.

Purpose of the Study:

• To systematically review the literature on cortisol, oxytocin, and oestradiol in psychotherapy.
• To identify baseline hormonal predictors of psychotherapy response.
• To examine hormonal changes as indicators of therapeutic change in depression and anxiety disorders.

Main Methods:

• Systematic literature search focusing on cortisol, oxytocin, and oestradiol.
• Inclusion criteria focused on psychotherapy, depression, and anxiety disorders.
• Analysis of studies examining hormonal predictors and treatment-related changes.

Main Results:

• Cortisol's role in psychotherapy is the most established among the studied hormones.
• Both cortisol and oxytocin show implications in psychotherapy, though causality requires further evidence.
• Hormonal roles appear differential between depression and anxiety psychotherapy.

Conclusions:

• Hormones offer potential insights into individual psychotherapy effectiveness.
• Future research directions include matching psychotherapy to endocrine states.
• Hormonal manipulation may offer avenues for improving psychotherapy outcomes.
