ICD-11 Criteria for Cyclothymic Disorder (6A62)

Cyclothymic disorder is characterised by a persistent instability of mood over a period of at least 2 years, involving numerous periods of hypomanic (e.g., euphoria, irritability, or expansiveness, psychomotor activation) and depressive (e.g., feeling down, diminished interest in activities, fatigue) symptoms that are present during more of the time than not. The hypomanic symptomatology may or may not be sufficiently severe or prolonged to meet the full definitional requirements of a hypomanic episode (see Bipolar type II disorder), but there is no history of manic or mixed episodes (see Bipolar type I disorder). The depressive symptomatology has never been sufficiently severe or prolonged to meet the diagnostic requirements for a depressive episode (see Bipolar type II disorder). The symptoms result in significant distress or significant impairment in personal, family, social, educational, occupational or other important areas of functioning.

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
