ICD-11Criteria for Body-Focused Repetitive Behaviour Disorders (6B25)

Body focused repetitive behaviour disorders are characterised by recurrent and habitual actions directed at the integument (e.g. hair-pulling, skin-picking, lip-biting), typically accompanied by unsuccessful attempts to decrease or stop the behaviour involved, and which lead to dermatological sequelae (e.g., hair loss, skin lesions, lip abrasions). The behaviour may occur in brief episodes scattered throughout the day or in less frequent but more sustained periods. The symptoms result in significant distress or significant impairment in personal, family, social, educational, occupational or other important areas of functioning.

6B25.0      Trichotillomania

Trichotillomania is characterised by recurrent pulling of one’s own hair leading to significant hair loss, accompanied by unsuccessful attempts to decrease or stop the behaviour. Hair pulling may occur from any region of the body in which hair grows but the most common sites are the scalp, eyebrows, and eyelids. Hair pulling may occur in brief episodes scattered throughout the day or in less frequent but more sustained periods. The symptoms result in significant distress or significant impairment in personal, family, social, educational, occupational or other important areas of functioning.

Inclusions:              

  • Compulsive hair plucking

Exclusions:             

  • Stereotyped movement disorder with hair-plucking (6A06)

6B25.1      Excoriation disorder

Excoriation disorder is characterised by recurrent picking of one’s own skin leading to skin lesions, accompanied by unsuccessful attempts to decrease or stop the behaviour. The most commonly picked sites are the face, arms and hands, but many individuals pick from multiple body sites. Skin picking may occur in brief episodes scattered throughout the day or in less frequent but more sustained periods. The symptoms result in significant distress or significant impairment in personal, family, social, educational, occupational or other important areas of functioning.

Inclusions:              

  • Skin picking disorder

Exclusions:             

  • Stereotyped movement disorder (6A06)
  • Acute excoriation of skin (ME62.9)
  • Chronic excoriation of skin (ME63.7)

6B25.Y                   Other specified body-focused repetitive behaviour disorders

6B25.Z                    Body-focused repetitive behaviour disorders, unspecified

  6B2Y                   Other specified obsessive-compulsive or related disorders

  6B2Z                   Obsessive-compulsive or related disorders, unspecified

ADVOKATE: A Mnemonic Tool for the Assessment of Eyewitness Evidence

By
ADVOKATE: A Mnemonic Tool for Assessment of Eyewitness Evidence A tool for assessing eyewitness  ADVOKATE is a tool designed to assess eyewitness evidence and how much it is reliable. It requires the user to respond to several statements/questions. Forensic psychologists, police or investigative officer can do it. The mnemonic ADVOKATE stands for: A = amount of time under observation (event and act) D = distance from suspect V = visibility (night-day, lighting) O = obstruction to the view of the witness K = known or seen before when and where (suspect) A = any special reason for remembering the subject T = time-lapse (how long has it been since witness saw suspect) E = error or material discrepancy between the description given first or any subsequent accounts by a witness.  Working with suspects (college.police.uk)

ICD-11 Criteria for Anorexia Nervosa (6B80)

By
ICD-11 Criteria for Anorexia Nervosa (6B80) Anorexia Nervosa is characterised by significantly low body weight for the individual’s height, age and developmental stage that is not due to another health condition or to the unavailability of food. A commonly used threshold is body mass index (BMI) less than 18.5 kg/m2 in adults and BMI-for-age under 5th percentile in children and adolescents. Rapid weight loss (e.g. more than 20% of total body weight within 6 months) may replace the low body weight guideline as long as other diagnostic requirements are met. Children and adolescents may exhibit failure to gain weight as expected based on the individual developmental trajectory rather than weight loss. Low body weight is accompanied by a persistent pattern of behaviours to prevent restoration of normal weight, which may include behaviours aimed at reducing energy intake (restricted eating), purging behaviours (e.g. self-induced vomiting, misuse of laxatives), and behaviours aimed at incr

Psychomotor disturbances, including catatonia, may be present. Persistent delusions, persistent hallucinations, thought disorder, and experiences of influence, passivity, or control are considered core symptoms. Symptoms must have persisted for at least one month in order for a diagnosis of schi
