The Trauma History Screen (THS)

(Carlson et al., 2011)

The THS is a 14-item self-report measure assessing exposure to trauma in adults. The THS can be used as a screening tool. The THS has not been used with adolescents, nor does a separate adolescent version exist. The THS consists of two parts. In part one, questions probe for traumatic events (e.g., “a really bad car, boat, train or aeroplane accident”) and the number of times the event(s) occurred. Respondents indicate “yes” or “no” and the number of times the event occurred. In part two, respondents can provide further details about endorsed events (Carlson et al., 2011). This measure was designed to be administered in about 4 minutes (Carlson et al., 2011). The THS demonstrates adequate test-retest reliability over a period of one to two weeks (k = .61 -.77; Carlson et al., 2011) and concurrent validity with the Traumatic Life Events Questionnaire (TLEQ; Kubany et al., 2000). The measure is available online (http://www.istss.org/AssessmentResources/5347.htm). (Carlson et al., 2011).

ADVOKATE: A Mnemonic Tool for the Assessment of Eyewitness Evidence

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.

ICD-11 Criteria for Anorexia Nervosa (6B80)

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

ICD-11 Criteria for Schizophrenia (6A20 )

ICD-11 Criteria for Schizophrenia (6A20 ) Schizophrenia is characterised by disturbances in multiple mental modalities, including thinking (e.g., delusions, disorganisation in the form of thought), perception (e.g., hallucinations), self-experience (e.g., the experience that one's feelings, impulses, thoughts, or behaviour are under the control of an external force), cognition (e.g., impaired attention, verbal memory, and social cognition), volition (e.g., loss of motivation), affect (e.g., blunted emotional expression), and behaviour (e.g., behaviour that appears bizarre or purposeless, unpredictable or inappropriate emotional responses that interfere with the organisation of behaviour). 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
