Does early emotional distress predict later child involvement in gambling?

OBJECTIVE Younger people are engaging in gambling, with some showing excessive involvement. Although a consequence of gambling could be anxiety and depression, emotional distress could be a precursor to gambling involvement. This could reflect developmental proneness toward problem behaviour. We assessed whether early emotional distress directly influences later gambling or if it operates through an indirect pathway. METHODS Using a prospective longitudinal design, an intentional subsample of children from the 1999 kindergarten cohort of the Montreal Longitudinal Preschool Study (Quebec) from intact families were retraced in 2005 for follow-up in Grade 6. Consenting parents and children were separately interviewed. Key child variables and sources included kindergarten teacher ratings of emotional distress and impulsivity and self-reported parent and child gambling. RESULTS Higher levels of teacher-rated emotional distress in kindergarten significantly predicted a higher propensity toward later gambling behaviour. Impulsivity, a factor often comorbidly present with emotional distress, completely explained this predictive relation above and beyond potential child- and family-related confounds, including parental gambling. CONCLUSIONS Children with higher levels of emotional distress at kindergarten were more inclined toward child gambling behaviour in Grade 6. The influence of early emotional distress completely vanished when behaviours reflecting impulsivity were considered when predicting later child gambling behaviour. The relation between emotional distress and child gambling involvement in children was thus explained by its comorbidity with early impulsivity. This study does not rule out the possibility that emotional distress could become a correlate or consequence of excessive involvement in gambling activities at a later developmental period.
