Psychiatry: core clinical skills
Psychiatric interview & mental state examination
The psychiatric interview and mental state examination (MSE) are how a psychiatrist gathers a full history and systematically examines a person's current mental state. They are the single most important clinical skill in psychiatry.
Depth by stage, Pre-U → Consultant (details)
What is it?
A psychiatric assessment usually takes much longer than a typical medical history. It covers the presenting problem, past psychiatric and medical history, family history, personal history from birth onwards, substance use, forensic history, previous personality and current social situation.
The mental state examination is a structured description of what the psychiatrist observes and elicits during the interview: appearance and behaviour, speech, mood and affect, thought form and content, perception, cognition and insight. Risk to self and others is assessed throughout.
Good interviewing is a skill of both structure and warmth: building trust, asking about sensitive topics such as suicide, sexuality or abuse, and adapting to the patient's language, culture and level of distress. In Malaysia this often means interviewing in Bahasa Malaysia, English or another language, sometimes with an interpreter, and involving family appropriately.
Why does a psychiatrist need it?
Almost every diagnosis and treatment decision in psychiatry rests on a well-conducted interview and MSE. They are also the core of clinical examinations (long case, OSCE and CASC), medico-legal reports and emergency decisions under the Mental Health Act.

Common questions
Why is a first psychiatric appointment so long?
Because the psychiatrist needs a full picture of the person's life, health, family and current state, not just the symptoms. This often takes an hour or more and sometimes needs information from family as well.
Is asking about suicide risky?
Research and clinical experience show that asking directly and calmly about suicidal thoughts does not plant the idea. It usually brings relief and allows proper help to be arranged.
