The Quinte longitudinal study

Abstract

In order to effectively prevent something, you need to know what causes it. Longitudinal research is the only way of understanding the critical junctures and precipitators that prevention efforts should be targeting--and in particular, which junctures appear earliest and thus provide the best opportunity for prevention. Longitudinal research to create an overarching etiological model of problem gambling is consistently identified as a top research need in the field. The Quinte Longitudinal Study began in 2006 with a sample of 4121 Ontario residents ages 17 to 89, including an oversample of 1056 'at risk' gamblers. These individuals have received a comprehensive annual assessment of all variables of epidemiological relevance to addictive behaviour and psychopathology (demographics; family history; physical health; gambling attitudes, gambling motivation and behavior; gambling availability; personality; stress; mental health status; social functioning and support; intelligence). No other longitudinal study of gambling comes close to the comprehensiveness and rigour of the {QLS.} The retention rate thus far achieved (94.2% after 4 years) is virtually unprecedented for large scale longitudinal research of psychopathology, and significantly enhances the scientific value of the project. Note: this project is also known as the {'Belleville} Study' and the {'Quinte} Exhibition and Raceway Impact Study'.
