Introduction: High drop-out rates in substance-use disorders patients (SUDP) require identifying early predictors of treatment outcome.
Objective: To investigate the relationship between executive functioning and treatment adherence in SUDP.
Method: Thirty-nine outpatients were evaluated at the initiation of a cognitive-behavioral treatment (CBT) in executive functions, including: updating (Letter-Number Sequencing; LNS), inhibition (Stroop Task) and shifting (Reversal Learning Task). A measure of self-reported craving was taken. Logistic regression analyses were used to explore the predictive capability of executive functions over treatment adherence in a 2 month follow-up.
Results: Greater score in LNS was the best predictor of treatment adherence (B=0.094; p=0.022). No other executive functions, nor craving, could predict this variable.
Conclusions: Updating seems to be a critical skill to cope with the high cognitive demands of CBT. Patients with alterations in this executive function could benefit from a specific neuropsychological rehabilitation, improving adherence to treatment for SUDP.
