  2. Definition

    Self-harm

    Self-harm is defined as non-fatal intentional self-poisoning or self-injury, regardless of motivation or intention. Events of poisoning and overdose with analgesics, although commonly implicated in suicidal behaviours, were not included as they are often accidental. We identify self-harm using all the concepts below in conjunction. These code lists are based on validated, published and comparable lists (Marchant et. al. 2020, Thomas et. al. 2014).

    Related concepts

    Self-Harm - Intentional (Aged 10+)

    This includes all forms of intentional self-harm in those 10 years of age and older, from non-suicidal self-injury through to suicide attempts, with the exception of intentional alcohol poisoning or overdose. A small number of codes do not distinguish between non-fatal and fatal self-harm descriptors. We have included these for completion's sake. Fatal events could be removed if linked to mortality records.

    Self-Harm - Undetermined Intent (Aged 15+)

    In this additional list we include events of undetermined intent for hanging, strangulation and suffocation; rifle shotgun and larger firearm discharges; other and unspecified firearm discharges; and falling and jumping from a high place in those 15 years of age and older, as they are likely unidentified self-harm events. When intent is not explicitly recorded (neither intentional nor undetermined), we include events of overdose of drug, biological substance or medicament (without further substance specification) and poisoning and overdose of antidepressants (commonly implicated in suicide) also for those 15 years of age and older, as they are also likely unidentified self-harm events.

    How to use

    To identify self-harm events, include all presentations at age 10 or older with code in Self-Harm - Intentional. Many UK National Health service and other official documents are based in this definition. However, validation studies have shown the benefit of also including presentations at age 15 or older with code in Self-Harm - Undetermined Intent (Thomas et. al. 2014).
