Leeds Dependence Questionnaire (LDQ)<\/strong><\/h2>\n

Recommended\u00a0frequency: Every 4\u00a0weeks
\n<\/em><\/p>\n

Summary<\/span><\/strong><\/h2>\n

The Leeds Dependence Questionnaire is a 10-item, self completion questionnaire designed to measure dependence upon a variety of substances. The LDQ has been shown to be understood and valid with people struggling with both alcohol and substance use.\u00a0The questionnaire was designed to be sensitive to change over time and to be sensitive through the range from mild to severe dependence.<\/p>\n

Psychometric Properties of the LDQ<\/span><\/strong><\/h2>\n

The initial validation study of the LDQ reported estimates of concurrent, discriminant and convergent validities, which are thought to be satisfactory. A principal components analysis produced a single factor accounting for 64% of the variance. Cronbach’s alpha was 0.94 and test-retest reliability was found to be 0.95.\u00a0The creators of the scale recommend using dependence as a continuous data variable.<\/p>\n

Other studies have shown the LDQ to have considerable promise as a brief, psychometrically sound, measure of substance dependence useful across a variety of substances, that has clinical and research utility.<\/p>\n
