Leeds Dependence Questionnaire

Raistrick, Bradshaw, Tober, Weiner, Allison, Healey | 1994 

A self-report instrument called the Leeds Dependence Questionnaire (LDQ) assesses the level of dependence in people with substance use disorders. The questionnaire was created by a research team at the University of Leeds in the UK and released for the first time in 1994.

The LDQ has 20 questions that look at many aspects of drug dependence, such as how much a person's drug use gets in the way of their daily lives, how strong their need is, how important the drug is to them, and how much they can control how much they use.

Usually given as a self-report questionnaire, the LDQ takes between 10 and 15 minutes to complete. The responses are evaluated from "not at all" to "always." The overall score, which reflects the intensity of the reliance, is created by adding the scores from each item.

The LDQ has been used in numerous research to evaluate the degree of dependence in people with substance use disorders and has been shown to have strong reliability and validity. The questionnaire has also been utilised in international studies and translated into several languages.

To sum up, the Leeds Dependence Questionnaire can help people with substance use disorders figure out how much they depend on a substance. It is a reliable and valid tool that gives useful information about the type and severity of addiction and can help with treatment planning and making decisions.

ICD-11 Criteria for Attention Deficit Hyperactivity Disorder (ADHD) 6A05

By
ICD-11 Criteria for Attention Deficit Hyperactivity Disorder (ADHD) 6A05 Attention deficit hyperactivity disorder is characterised by a persistent pattern (at least 6 months) of inattention and/or hyperactivity-impulsivity that has a direct negative impact on academic, occupational, or social functioning. There is evidence of significant inattention and/or hyperactivity-impulsivity symptoms prior to age 12, typically by early to mid-childhood, though some individuals may first come to clinical attention later. The degree of inattention and hyperactivity-impulsivity is outside the limits of normal variation expected for age and level of intellectual functioning. Inattention refers to significant difficulty in sustaining attention to tasks that do not provide a high level of stimulation or frequent rewards, distractibility and problems with organisation. Hyperactivity refers to excessive motor activity and difficulties with remaining still, most evident in structured situations that re...
