[Towards DSM 5.1. Proposals for schizophrenia.]

Area of Science:

• Psychiatry
• Clinical Psychology

Background:

• Schizophrenia affects 1% of the global population, presenting with positive and negative symptoms.
• Current diagnostic criteria in the DSM-5 aim for accuracy but are subject to ongoing research for improvement.

Purpose of the Study:

• To propose a novel diagnostic approach for schizophrenia by introducing adherence to treatment as a specifier.
• To investigate the potential benefits of differentiating schizophrenia based on treatment adherence.

Main Methods:

• The study is based on existing evidence regarding treatment adherence in schizophrenia patients.
• Hypothesizing two distinct subtypes: poor adherence schizophrenia and good adherence schizophrenia.

Main Results:

• Evidence suggests reduced relapses, rehospitalizations, and better long-term illness course in non-adherent schizophrenia patients.
• Treatment adherence significantly impacts patient attitudes, quality of life, and subjective well-being.

Conclusions:

• Introducing adherence as a schizophrenia specifier is a compelling hypothesis.
• This new classification could lead to more precise diagnosis and tailored treatment strategies for schizophrenia.
