The Inventory of Depressive Symptoms and the Quick Inventory of Depressive Symptoms (IDS and QIDS)

 Rush et al., 1986; Rush, Gullion, Basco, Jarrett, & Trivedi, 1996; Rush et al., 2003).

The IDS/QIDS can be used as a screening tool; the QIDS is also appropriate to use as a diagnostic tool and to monitor symptom change over time (IDS-QIDS.org, 2013). The IDS/QIDS has not been used with adolescents, nor does a separate adolescent version exist. The IDS (30-item) and QIDS (16-item) are self- and clinician-report measures assessing depressive symptoms in adults. The briefer QIDS queries for only the nine major depressive disorder domains outlined in the Diagnostic and Statistical Manual of Mental Disorders 4th ed, Text Revision (DSM-IVTR, American Psychiatric Association, 2010), where the IDS queries for these domains as well as associated symptoms such as anxiety and irritability. Each item is rated from zero (“does not feel sad”) to three (“feels intensely sad virtually all the time”; Rush et al., 1986). The IDS is designed to be administered in 10 to 15 minutes while the QIDS takes five to seven minutes. IDS total scores range from 0 to 84. QIDS total scores range from 0 to 27. The IDS and QIDS both demonstrate good to excellent internal consistency (α = .81-.94; Trivedi, 2004). Both the IDS and QIDS demonstrate concurrent validity with the HAM-D (Hamilton, 1960; Rush et al., 1996; Rush et al., 2004). Both the IDS and the QIDS are available in many languages including English, Spanish, Danish, French, and Turkish. The measures are available online (http://www.ids-qids.org).

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

ICD-11 Criteria for Schizophrenia (6A20 )

By
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
