Insight, the law and psychiatry: Going round in circles or playing nice?

Area of Science:

• Psychiatry
• Mental Health Law
• Clinical Psychology

Background:

• Insight is a key aspect of psychosis, influencing clinical outcomes.
• The construct of insight is debated, particularly in medicolegal contexts regarding involuntary treatment.
• Lack of insight is often used to justify involuntary treatment and admission.

Purpose of the Study:

• To review arguments on using insight as evidence in involuntary treatment and hospital admission cases.
• To clarify the role of insight in healthcare decision-making capacity.
• To guide clinicians and legal practitioners on the beneficial use of insight in discussions.

Main Methods:

• Narrative review of the insight construct in clinical psychiatry and medicolegal settings.
• Analysis of case material, including a specific case from the England and Wales Court of Protection (CoP).

Main Results:

• Insight is often cited for non-compliance and diagnosis rejection, but can involve circular reasoning.
• Criticism exists regarding the definition and use of insight in legal settings (e.g., by NICE).
• Understanding insight clarifies how psychosis impairs capacity, potentially necessitating care without consent.

Conclusions:

• Insight is frequently discussed in psychopathology and medicolegal arguments.
• Practitioners must define insight clearly and explain its relation to mental capacity, especially in expert testimony.
• Poor insight is integral to psychosis, closely linked to lack of capacity and should not be treated separately.
