The mental state examination (MSE) is a structured way of observing and describing a patient’s current state of mind, under the domains of appearance, attitude, behaviour, mood, affect, speech, thought process, thought content, perception, cognition, insight and judgement. Show
The purpose of the MSE is to obtain a comprehensive cross-sectional description of the patient’s mental state, which when combined with the biographical and historical information of the psychiatric history, allows the clinician to make an accurate diagnosis and formulation. Below is a framework that demonstrates the type of information that the mental state examination hopes to gather.

Opening the consultationWash your hands and don PPE if appropriate. Introduce yourself to the patient including your name and role. Confirm the patient’s name and date of birth. Ask the patient if they’d be happy to talk with you about their current issues. You might also be interested in our OSCE Flashcard Collection which contains over 2000 flashcards that cover clinical examination, procedures, communication skills and data interpretation. AppearanceThe appearance of the patient may provide some clues as to their lifestyle, current mental state and ability to care for themselves. Observe the patient’s general appearance:
BehaviourA patient’s behaviours may provide insights into their current mental state. Engagement and rapportNote if the patient appears engaged in the consultation and if you are able to develop a rapport with them. Note if they appear distracted or if they appear to be engaging with hallucinations (e.g. replying to auditory hallucinations in schizophrenia). Eye contactObserve the patient’s level of eye contact and note if this appears reduced or excessive. Facial expressionObserve the patient’s facial expression (e.g. relaxed, angry, disengaged). Body languageObserve the patient’s body language which may appear threatening (e.g. standing up close to you) or withdrawn (e.g. curled up or hands covering their face). Note any evidence of exaggerated gesticulation or unusual mannerisms. Psychomotor activityObserve for any evidence of psychomotor abnormalities:
Abnormal movements or posturesNote any abnormal movements or postures:
SpeechAssess the patient’s speech to identify abnormalities which may indicate underlying mental health issues. Rate of speechPay attention to the patient’s rate of speech:
Quantity of speechNote the quantity of the patient’s speech:
Tone of speechNote the tone of the patient’s speech:
Volume of speechNote the volume of the patient’s speech. Fluency and rhythm of speechNote the fluency and rhythm of the patient’s speech for abnormalities:
Mood and affectMood and affect both relate to emotion, however, they are fundamentally different. Affect represents an immediately expressed and observed emotion (e.g. the patient’s facial expression or overall demeanour). Mood represents a patient’s predominant subjective internal state at any one time as described by them. Affect is what you observe and mood is what the patient tells you. MoodA patient’s mood can be explored by asking questions such as:
Examples of mood states
AffectTo assess affect you need to observe the patient’s facial expressions and overall demeanour. Apparent emotionObserve the apparent emotion reflected by the patient’s affect, examples may include:
Range and mobility of affectRange and mobility of affect refer to the variability observed in the patient’s affect during the assessment. Abnormalities may include:
Intensity of affectA patient’s intensity of affect may be described as:
Congruency of affectNote if the patient’s affect appears in keeping with the content of their thoughts (known as congruency). A patient sharing distressing thoughts whilst demonstrating a flat affect or laughing would be described as showing incongruent affect. Incongruent affect is typically associated with schizophrenia. ThoughtThought can be described in terms of form, content and possession. Thought formThought form refers to the processing and organisation of thoughts. Speed of thoughtsPatient’s may demonstrate abnormally fast (i.e. racing) or abnormally slow thought processing. Flow and coherence of thoughtsIn healthy individuals, thoughts flow at a steady pace and in a logical order. However, in several mental health conditions, the flow and coherence of thoughts can become distorted. Abnormalities of thought flow and coherence include:
Thought contentAbnormalities of thought content can include:
Some examples of questions which can be used to screen for thought content abnormalities include:
Thought possessionAbnormalities of thought possession include:
Some examples of questions which can be used to screen for thought possession abnormalities include:
PerceptionPerception involves the organisation, identification and interpretation of sensory information to understand the world around us. Abnormalities of perception are a feature of several mental health conditions. Abnormalities of perception include:
Some examples of questions which can be used to screen for perceptual abnormalities include:
CognitionCognition refers to “the mental action or process of acquiring knowledge and understanding through thought, experience, and the senses”. Cognition can be impaired as a result of mental health conditions and their treatments. Throughout the process of performing a mental state examination, you will develop a vague idea of the patient’s cognitive performance including:
A formal assessment of cognition can be achieved through a variety of different validated clinical tests including:
Insight and judgementInsightInsight, in a mental state examination context, refers to the ability of a patient to understand that they have a mental health problem and that what they’re experiencing is abnormal. Several mental health conditions can result in patients losing insight into their problem. Some examples of questions which can be used to assess insight include:
JudgementJudgement refers to the ability to make considered decisions or come to a sensible conclusion when presented with information. Judgement can become impaired in several mental health conditions leading to poor decision making. You may get some idea of the patient’s judgement abilities as you move through the mental state examination, but you can also specifically assess judgement by presenting the patient a scenario such as:
Sensible judgement in this situation would involve leaving the house immediately wherever possible and calling the fire department. A patient with impaired judgement may suggest ignoring it. Closing the consultationAsk the patient if they have any questions or concerns that have not been addressed. Thank the patient for their time. References
