The primary aim of this proposal is to enhance the diagnostic framework for schizophrenia by integrating two theoretical models:

• DIKWP Model: A hierarchical framework consisting of Data, Information, Knowledge, Wisdom, and Purpose.

• Four Spaces Framework: Comprising Conceptual Space, Cognitive Space, Semantic Space, and Conscious Space.

By incorporating these models, the proposal seeks to:

• Supplement Existing Criteria: Enhance the depth and breadth of assessment without replacing established diagnostic guidelines such as DSM-5 and ICD-11.

• Promote Holistic Understanding: Recognize the complex interplay of biological, psychological, social, and cultural factors in schizophrenia.

• Facilitate Personalized Care: Tailor interventions to individual needs, promoting recovery and improved quality of life.

The integration addresses several key aspects:

• Complexity of Schizophrenia: Acknowledges that schizophrenia is multifaceted, requiring a multidimensional assessment approach.

• Dynamic Nature of Diagnosis: Emphasizes that diagnosis is not a static event but a continuous process involving data transformation and adaptation.

• Ethical and Cultural Sensitivity: Ensures that diagnostic practices respect patient autonomy, cultural beliefs, and ethical considerations.

• Scope: The proposal is intended for clinicians, researchers, and academics interested in advancing the diagnostic process for schizophrenia.

• Limitations: It is a theoretical framework that requires empirical validation and should not be applied clinically without further research and consensus.

This proposal is for educational and academic discussion purposes. It does not replace existing diagnostic criteria and should not be used as a standalone diagnostic tool in clinical practice. Clinical application should adhere to established guidelines and regulatory requirements.

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), provides the following criteria for diagnosing schizophrenia:

• Criterion A: Characteristic Symptoms

  Two (or more) of the following, each present for a significant portion of time during a one-month period (less if successfully treated). At least one must be (1), (2), or (3):

1. Delusions

2. Hallucinations

3. Disorganized Speech (e.g., frequent derailment or incoherence)

4. Grossly Disorganized or Catatonic Behavior

5. Negative Symptoms (e.g., diminished emotional expression or avolition)

• Criterion B: Social/Occupational Dysfunction

  For a significant portion of the time since the onset, one or more major areas of functioning such as work, interpersonal relations, or self-care are markedly below the level achieved prior to onset.

• Criterion C: Duration

  Continuous signs of disturbance persist for at least six months. This six-month period must include at least one month of symptoms (or less if successfully treated) that meet Criterion A.

• Criterion D: Schizoaffective and Mood Disorder Exclusion

  Schizoaffective disorder and depressive or bipolar disorder with psychotic features have been ruled out.

• Criterion E: Substance/General Medical Condition Exclusion

  The disturbance is not attributable to the physiological effects of a substance or another medical condition.

• Criterion F: Relationship to Autism Spectrum Disorder or Communication Disorder

  If there is a history of these disorders, additional diagnosis of schizophrenia is made only if prominent delusions or hallucinations are also present.

The International Classification of Diseases, Eleventh Revision (ICD-11), outlines the following for schizophrenia:

• Core Symptoms:

• Persistent delusions

• Hallucinations

• Thought disorder (disorganized thinking)

• Experiences of influence, passivity, or control

• Disorganized behavior

• Negative symptoms

• Duration:

  Symptoms must be present for at least one month.

• Exclusions:

• The diagnosis should not be made if the symptoms are better explained by mood disorders, substance use, or medical conditions.

• Subtypes:

  ICD-11 does not specify subtypes but allows for specifiers such as acute, first-episode, multiple episodes, or continuous.

The DIKWP model provides a hierarchical framework for understanding the transformation of raw data into purposeful action. In the context of schizophrenia diagnosis, it offers a structured approach to assessment and intervention.

Final Remarks

This detailed proposal offers a comprehensive framework for the diagnosis of schizophrenia, integrating the DIKWP model and Four Spaces framework to enhance traditional criteria. By considering data transformation processes, cognitive functions, language use, and ethical considerations, clinicians can achieve a more nuanced understanding of the disorder.

The implementation of this framework requires multidisciplinary collaboration, cultural sensitivity, and adherence to ethical standards. While promising, it is essential to validate this approach through empirical research and professional consensus before widespread clinical adoption.
