1. Objectifs

Intentions :
«[T]he goals of the present study were 1) to examine whether impulsivity and socio-family risk can explain the concurrent, and possibly longitudinal, links between gambling problems and depressive symptoms, and 2) to investigate possible cross-lagged links between gambling problems and depressive symptoms from adolescence to early adulthood, that may occur even when possible antecedent factors are controlled.» (p. 132)

2. Méthode

Échantillon/Matériau :
«Participants were part of an ongoing longitudinal study that started in 1984 with 1162 kindergarten boys. They attended 53 schools in economically disadvantaged areas in Montreal, Canada (Mean age = 6.02; SD = .52).» (p. 133) The final sample include 1004 boys that provided at least one of the wanted measures.

3. Résumé

To achieve their purpose, authors proposed «[…] three competing models […]: a ‘Common antecedents’ model, a ‘Direct influence’ model, and a ‘Mixed’ model. The results provided support for the Mixed model. Impulsivity, but not socio-family risk, was linked to the initial level of gambling problems and depressive symptoms in adolescence. When this common antecedent factor was controlled, the concurrent relation between gambling problems and depressive symptoms in adolescence disappeared. Once in place, however, gambling problems and depressive symptoms appeared to influence each other over time from late adolescence to early adulthood. This direct effect accounted for the concurrent relation between gambling problems and depressive symptoms in young adulthood.» (p. 135)
