An evaluation of the Leeds Dependence Questionnaire

Two studies arc reported investigating the utility of the Leeds Dependence Questionnaire. In Study 1, 203 students enrolled in drug and alcohol courses at a tertiary institution were administered the LDQ along with the AUDIT, other screening measures of risk of alcohol related problems and a test of psychopathology. The outcome from this investigation showed the LDQ to have good internal consistency and reliability, to predict alcohol use even after controlling for other variables, and to be best described by a two factor solution, although a single common factor could be identified. Study 2 investigated the LDQ with a sample of juvenile delinquents. This study also found good internal consistency, and stronger support for a single factorial solution. The LDQ was able to predict increased frequency of a variety of substances abused by the delinquents. It was concluded that the scale was a Kood, brief evaluation tool.
