Which Psychotherapy Model Should be Used in Psilocybin Treatment for Depression?

Area of Science:

• Psychiatry
• Psychology
• Pharmacology

Background:

• Depression impacts millions globally, with many cases resistant to standard treatments.
• Psilocybin-assisted psychotherapy (PAP) shows therapeutic potential for depression.
• The optimal psychotherapy model for PAP remains unclear, with varied approaches documented.

Purpose of the Study:

• To conceptualize and compare psychotherapy models used in PAP for depression.
• To review the characteristics and efficacy evidence of different PAP psychotherapy approaches.

Main Methods:

• A narrative review of interventional trials evaluating PAP for unipolar or bipolar depression.
• Searches conducted across PubMed, PsycINFO, and Google Scholar databases.

Main Results:

• Two main psychotherapy models were identified: 'Specific' (e.g., ACT, PCT) and 'Non-specific' psychological support.
• Both models value the therapeutic alliance but differ in mechanistic focus (psychological flexibility vs. 'inner-healer').
• Identified literature gaps include methodological limitations and the need for standardized reporting.

Conclusions:

• Both specific and non-specific PAP models may offer clinical relevance for depression.
• Future research should focus on standardized reporting and comparative designs to evaluate PAP models.
• Informing treatment guidelines requires further investigation into the efficacy of different PAP psychotherapy approaches.
