Beck Depression Inventory BDI 1 and 2

Beck Depression Inventory BDI 1 and 2

Commonly Used Clinical Scales 

Beck Depression Inventory

The Beck Depression Inventory created by Aaron T. Beck is a 21-question multiple-choice self-report inventory, one of the most widely used psychometric tests for measuring the severity of depression.

In its current version, the BDI-II is designed for individuals aged thirteen and over and is composed of items relating to symptoms of depression such as hopelessness and irritability.

Versions

There are three versions of the BDI

  1. Original BDI, first published in 1961.

  2. Revised in 1978 as the BDI-1A

  3. the BDI-II published in 1996. 

The BDI is widely used as an assessment tool by health care professionals and researchers in a variety of settings.

The BDI-II was developed in response to the American Psychiatric Association's publication of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, which changed many of the diagnostic criteria for Major Depressive Disorder. Participants were asked to rate how they have been feeling for the past two weeks, as opposed to the past week as in the original BDI.

The BDI-II contains 21 questions, each answer being scored on a scale value of 0 to 3. Higher total scores indicate more severe depressive symptoms. The standardized cutoffs used differ from the original:

0–13: minimal depression

14–19: mild depression

20–28: moderate depression

29–63: severe depression.

BDI-II is positively correlated with the Hamilton Depression Rating Scale with a Pearson r of 0.71. The test was also shown to have a high one-week test-retest reliability (Pearson r =0.93) and high internal consistency (α=.91).

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
