Clinical Trial Summary

Addictions are among the most serious and expensive public health problems in Europe and Spain and they present high morbimortality. There is an increasing amount of studies emphasizing the role e-health for improving current treatments in mental health but research in addictions is still scarce. Over the last years, there have been several indicators that show an upward trend in the consumption of cocaine and the highly treatment-resistant patients. Objectives: 1) To evaluate whether adding a web-based cognitive behavioral therapy (CBT4CBT) to standard cocaine use disorder treatment improves treatment outcomes in a Spanish sample of patients with severe addiction 2) To explore differences between men and women in treatment response and psychopathological risk factors of treatment response. Design: Randomized clinical trial. Selection criteria: patients consecutively admitted to the inpatient treatment unit for cocaine detoxification and meet inclusion criteria. Sample: the total sample will be of 70 individuals (randomly assigned to TAU + web-based CBT4CBT (n=35) or to TAU (n=35)). Assessment: Patients will be assessed at the beginning and during inpatient treatment, before and during outpatient treatment (CBT4CBT or TAU), after outpatient treatment (CBT4CBT or TAU) and at follow ups. Treatment retention, changes on craving and related psychological variables as well as presence of benzoylecgonine in urine will be evaluated.
