Crisis Intervention and Mental Health Response
What this domain tests
Crisis Intervention and Mental Health Response tests your ability to recognize a behavioral health crisis, use time and communication, and apply Massachusetts civil commitment authority correctly without treating mental illness as dangerousness.
Core rules
- G.L. c. 123, section 12 allows a police officer to take a person into temporary custody and transport for evaluation when there is reasonable belief of mental illness and a likelihood of serious harm.
- Section 12 is not a criminal charge and does not require an arrest; document the specific facts supporting dangerousness.
- Crisis intervention uses active listening, a calm tone, simple language, and one speaker. Reduce stimulation and give the person space.
- Suicide risk is assessed with direct questions; remove means when lawful and safe; do not leave the person alone if risk is imminent.
- Recognize autism, dementia, traumatic brain injury, and substance intoxication as possible causes of unusual behavior.
- Collaborate with mobile crisis teams, hospital emergency departments, and family when appropriate.
Worked example
A woman stands on a bridge saying people are following her. Officers contain traffic, keep a distance, and assign one communicator. She says she wants to die. The officer asks directly about suicide and learns she has a plan. The officer takes her into protective custody under section 12 and transports her for evaluation, documenting the statements and the bridge location. Force is not used because there is no imminent threat requiring it.
Traps
Equating mental illness with violence; using section 12 without facts of dangerousness; overwhelming the person with multiple officers talking; and promising confidentiality or outcomes you cannot guarantee.
