03 Behavioral Health Assessment
Learn how to conduct a respectful behavioral health assessment, describe mental status, respond to safety concerns, and document findings and follow-up.
Purpose and scope
A brings together the patient’s account, relevant history, observed behavior, a focused , and risk . It helps identify immediate safety or medical needs, guide care, and establish a baseline for reassessment. A result signals whether further evaluation may be needed; it is not, by itself, a diagnosis or a complete risk assessment.
The patient’s report is important, but it may be incomplete or affected by distress, cognition, intoxication, or other factors. When symptoms are new, fluctuate, or occur with changes in consciousness or attention, assess for possible acute medical causes.
Interview and information gathering
Begin by introducing your role, explaining the purpose of the interview, and using a calm, respectful, nonjudgmental manner. When possible, speak with the patient in a private, quiet setting. Start with open-ended questions, such as “What has been most difficult for you lately?”, then use direct questions to clarify. Allow time for answers, reflect the patient’s words, and check your understanding.
Use a : explain what you are doing, ask permission when appropriate, offer choices, and avoid pressing for unnecessary details. Consider the patient’s language, culture, developmental level, disability, and preferences. Use a qualified interpreter when needed rather than relying on a companion for sensitive assessment.
Gather information about the concern and its context, including:
Presenting concern: onset, duration, frequency, severity, triggers, recent changes, and effects on daily functioning.
Mood and symptoms: depression, anxiety, irritability, sleep, appetite, energy, concentration, elevated mood, unusual perceptions, and changes in thinking or behavior.
Safety and stressors: thoughts of self-harm or suicide, thoughts of harming others, recent losses or conflict, abuse or exploitation, and whether the patient feels safe where they live.
Health and treatment history: prior mental health concerns, hospitalizations, self-harm or suicide attempts, current and past treatment, medications, medical conditions, pain, and family history when relevant.
Substance use: substances used, amount, frequency, last use, and related effects. Consider intoxication or withdrawal as possible contributors to current symptoms.
Strengths and supports: coping strategies, trusted people, cultural or spiritual resources, responsibilities, and reasons for living.
With appropriate consent and within applicable rules, from records or trusted supports can help clarify the history.
Describing the
The (MSE) is a structured description of the patient’s presentation during the interview. Record what you observe and what the patient reports, and avoid treating a single observation as a diagnosis.
Assess and describe the following elements:
Appearance and behavior: grooming, dress, eye contact, posture, cooperation, psychomotor activity, and notable behaviors. Use neutral descriptions.
Speech: rate, volume, rhythm, fluency, and amount. For example: “Speech rapid and difficult to interrupt.”
Mood: the patient’s own description of their emotional state, preferably in their words.
Affect: observable emotional expression, including range, intensity, stability, and whether it is consistent with the conversation.
Thought process: how ideas are organized and connected, such as linear, tangential, or difficult to follow. Include a brief example if useful.
Thought content: main concerns, unusual beliefs, preoccupations, hopelessness, and thoughts of suicide, self-harm, or harming others. Ask directly about safety rather than inferring it from appearance.
Perception: reported or observed hallucinations or other unusual sensory experiences. Ask what the patient experiences and whether it affects safety.
Cognition: alertness, attention, orientation as appropriate, and memory or concentration concerns. Interpret findings in context.
Insight and judgment: the patient’s understanding of their situation and ability to consider consequences or make decisions relevant to care and safety.
For example: “Patient is awake and cooperative, with limited eye contact. Speech is soft and slowed. Describes mood as ‘down’; affect is constricted. Thought process is linear. Reports difficulty sleeping and denies current thoughts of suicide or harming others. Attention is sustained during interview.” This documents findings without assigning a diagnosis.
Risk and safety response
Ask directly and plainly about safety. For suicide risk, clarify whether thoughts are present now or have occurred recently, and ask about their frequency and intensity; any plan, intent, access to means, or preparatory behavior; and any previous attempts or self-injury. Also explore relevant stressors, substance use, supports, and risk and protective factors. Asking directly is part of assessment, not a substitute for clinical judgment.
Use validated and assessment tools when appropriate, but do not rely on a score alone to determine disposition. A positive screen should lead to a more focused safety assessment by a trained clinician, following the organization’s protocol and the tool’s instructions. Risk can change, so reassess after significant changes in symptoms, circumstances, or care setting.
The organizes this work into identifying risk and protective factors, suicide inquiry, determining risk and intervention, and documenting the plan. If the patient reports current suicidal thoughts or other signs of immediate danger, stay with the patient, promptly notify the responsible clinician, and initiate the facility’s emergency safety procedures. Arrange urgent evaluation as indicated; do not leave the patient alone while urgent help is being organized. NIMH’s adult outpatient guidance calls for urgent evaluation when a patient reports current thoughts of killing themselves.
Ask about possible abuse, neglect, or exploitation privately and sensitively when safe to do so. Record the patient’s words and objective findings, avoid leading questions, and follow organizational procedures and applicable reporting requirements. If there is a credible, immediate threat to the patient or another person, act promptly under local policy.
Documentation and follow-up
Document promptly, clearly, and objectively. Distinguish observation from interpretation, and include only details actually assessed and actions actually completed.
Include:
Context: date and time, setting, who was present, and relevant limits to the assessment, such as the need for an interpreter.
Patient report: presenting concern, relevant symptoms and history, and direct quotations for important statements.
Observed findings: MSE elements, behavior, and relevant physical or functional observations.
Risk assessment: tool and result; direct findings about ideation, plan, intent, access, and past behavior; risk and protective factors; and the clinical rationale for next steps. Do not document only “safe” or “no risk.”
Actions and response: notifications, consultation, safety measures, referrals, education, and the patient’s response or stated understanding.
Plan: disposition, follow-up arrangements, and reassessment needs. Document any declined care and the actions taken in response.
For example: “At 14:10, patient stated, ‘I’ve thought about not waking up,’ but denied current intent or a plan. Reports a prior attempt approximately two years ago; details reviewed. Identified sister as a support and agreed to speak with the clinician today. Responsible clinician notified at 14:18; safety assessment and follow-up plan initiated per protocol.” SAFE-T guidance emphasizes documenting risk level and rationale, interventions, and follow-up.
