Frequently asked questions

How did the Mental Health Act 2007 change the definition of mental disorder?
The Mental Health Act 2007 replaced the previous four categories of mental disorder with a single, broader definition. Under this new framework, mental disorder is defined as 'any disorder or disability of the mind'. This change simplified the legal criteria used to determine if a person meets the threshold for mental health intervention under the law.
What is the difference between the old treatability test and the new appropriate treatment test?
The Act replaced the old 'treatability test' with an 'appropriate treatment' test. This means that for detention or treatment orders to be valid, appropriate medical treatment must be available for the patient. The focus shifted from whether the condition could be treated to whether suitable treatment options exist for the individual's specific needs.
What new professional roles were created by the Mental Health Act 2007?
The Act created the role of the Responsible Clinician, which replaced the previous role of the Responsible Medical Officer (RMO). It also established the role of the Approved Mental Health Professional (AMHP), which replaced the Approved Social Worker (ASW). These changes were designed to clarify professional responsibilities and broaden the range of professionals involved in mental health decision-making.
How did the Act change the rights and role of the nearest relative?
The Act reformed the provisions regarding the nearest relative. It allows for the nearest relative to be displaced and replaced by the county court. Additionally, the legislation introduced independent mental health advocates (IMHAs) to support detained patients, ensuring they have access to independent support during their detention.
