The Adult Mental Health Assessment Process

1. Initial Referral

Your GP usually initiates the process by referring you to local NHS services. In urgent cases, the crisis team may intervene.

2. Triage and Screening

Following the referral, NHS services will triage based on urgency and assign a mental health professional to your case.

3. Face-to-Face or Remote Consultation

During the assessment, the clinician will explore:

• Current symptoms and their duration
  
  
• Personal and family psychiatric history
  
  
• Medical conditions and medications
  
  
• Lifestyle, substance use, relationships, employment, and housing
  
  

This holistic review ensures accurate diagnosis and care planning.

4. Risk Assessment

The practitioner will assess for:

• Risk of self-harm or suicide
  
  
• Risk to others
  
  
• Vulnerability and safeguarding concerns
  
  

5. Diagnosis and Recommendations

Once the assessment is completed, the clinician may provide:

• A formal diagnosis (e.g., depression, schizophrenia, PTSD)
  
  
• Treatment recommendations including therapy, medication, or community support
  
  
• Referral to specialist services if needed
  
  

Key Components of NHS Mental Health Assessments

What Happens After the Assessment?
