Los Angeles Symptom Checklist (LASC; King, King, Leskin, & Foy, 1995).

 Los Angeles Symptom Checklist (LASC; King, King, Leskin, & Foy, 1995).

The LASC is a 43-item self-report measure assessing symptoms of PTSD in adults and adolescents.  The LASC can be used as a screening and diagnostic tool (King et al., 1995). The LASC consists of items corresponding to the DSM-IV criteria for PTSD and items assessing distress and adjustment problems. Sample items include, “Vivid memories of unpleasant prior experiences” and “Waking early in the morning.” Each item is rated on a scale from zero (“not a problem”) to four (“extreme problem”). A preliminary diagnosis of PTSD can be determined using the 17 items within the scale that correspond to the DSM-IV criteria for PTSD.  A response counts towards the preliminary diagnosis if it is rated as a 2 or higher. The LASC was designed to be administered in 10-15 minutes (Orsillo, 2001). The LASC demonstrates excellent internal consistency for both the 17 items correlated with DSM-IV criteria (α = .94) and for the total score (α = .97). For use in adolescents, the LASC has demonstrated excellent internal consistency for the 17 items associated with DSM-IV criteria (α = .90) and the total score (α = .95; (Foy et al.,1997). The LASC demonstrates convergent validity with measures of combat exposure and other measures of PTSD symptomatology (Orsillo, 2001). It has also demonstrated a 75.6% accuracy in predicting a PTSD diagnosis from a structured interview (King, 1995). The measure can be obtained via (dfoy@pepperdine.edu).

ADVOKATE: A Tool for Assessment of Eyewitness Evidence

ADVOCATE: A Tool for Assessment of Eyewitness Evidence It is a tool designed to assess the eyewitness evidence that how much it is reliable. It requires the user to respond to several statements/questions. Forensic psychologist, 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)

Diagnostic test for catatonia, the lorazepam challenge test

Benzodiazepines are the mainstay of the treatment of catatonia and are also helpful as a diagnostic probe. A positive Lorazepam Challenge Test validates the diagnosis of catatonia. After we examine the patient for signs of catatonia, 1 or 2 mg of lorazepam is administered intravenously. After 5 minutes, the patient is re-examined. If there has been no change, a second dose is given, and the patient is again reassessed (46, 78). A positive response is a marked reduction (e.g., at least 50%) of catatonic signs and symptoms, as measured with a standardized rating scale. Favorable responses usually occur within 10 min (46). If lorazepam is given intramuscularly or per os, the interval for the second dose should be longer: 15′ and 30′, respectively. Many clinicians will share the experience that a “lorazepam test” not only confirms the diagnosis of catatonia but that it also makes the underlying psychopathology apparent “by permitting mute patients to speak” (79). Analogous to the lorazepa

Classification of Depression According to the ICD-10

A first depressive episode, duration at least15 days →depressive episode (F32)  A first depressive episode, severe and rapid onset, duration less than 15 days →still depressive episode (F32) A depressive episode can be mild (2 core symptoms, 2 other symptoms from the list) (32.0) moderate (2 core symptoms, 3 or preferably 4 other symptoms) (32.1) Severe (3 core symptoms, 4 other symptoms) without psychotic symptoms (32.2) (no delusion, hallucination or stupor) Severe with psychotic symptoms (above plus either delusions, hallucinations or stupor) (F32.3) Delusions can be mood-congruent or incongruent (neutral delusions e.g. delusions of reference are considered mood incongruent. None of them count towards schizoaffective disorder unless one of the first-rank)  A mild and moderate depressive episode can be  with somatic syndrome (four or more somatic symptoms, or three very severe somatic symptoms) without somatic syndrome (three or less somatic symptoms, not severe)  A severe depressi
