Résumé
"Background: Increasing evidence suggests that delay discounting may change following effective interventions. Nonetheless, previous studies that assessed the effect of contingency management (CM) on delay discounting are scarce, and their results are mixed. The current study assessed whether CM in conjunction with a cognitive-behavioral treatment (CBT) for smoking cessation was associated with changes in delay discounting at end-of-treatment and at 6-month follow-up compared to CBT alone. Method: One hundred and sixteen treatment-seeking smokers were randomly assigned either to CM + CBT (n = 69) or to CBT alone (n = 47). Participants completed delay discounting assessments at the intake, at end-of-treatment, and at 6-month follow-up. We evaluated CM’s effect on discounting with parametric and nonparametric methods. Results: Between-group analyses showed that none of the interventions changed delay discounting from intake to end-of-treatment or to 6-month follow-up. Nonetheless, some within-group analyses showed that the CM + CBT condition evidenced some degree of reduction. Conclusions: The current results suggest that CM intervention is not robustly associated with delay discounting changes. Future studies should address treatments that may potentially change delay discounting."
