Study Arms (2)

TIMCA

EXPERIMENTAL

The intervention will combine elements of motivational interviewing, cognitive and behavioral therapy and an attachment-based intervention. Sessions with both the adolescent and his parents are planned.

Other: TIMCA

Treatment as Usual

ACTIVE COMPARATOR

The comparator, an active control, will be Treatment As Usual" (TAU) group, i.e., the therapy usually practiced in the services. Given the multiplicity of investigating centers and the different treatments offered according to the patient's problems, it seems difficult to choose a single reference treatment for the control arm. Each investigating center undertakes to adopt the treatment that seems most effective and appropriate for each patient

Other: Treatment as Usual

Interventions

TIMCA is an individual therapy that will include the parents at certain points in the therapy . It will consist of two sessions of MI, two sessions of CBT, five sessions of ABI and one final session of summary to conclude the therapy.

Model Details: This will be a single-blinded, randomised, comparative therapeutic interventions, controlled trial. This is a prospective, randomized, single-blind, two-arm, parallel, multicenter study to evaluate the non-inferiority of an Integrative Therapy for Adolescent Cannabis Misuse (TIMCA) compared to the Treatment As Usual (TAU) control group using an Adaptive Group-Sequential non Inferiority Study Design. Two interim analyses are planned (when 30 and 60 subjects have completed the study). Both interventions will take place under similar conditions: 10 sessions, once a week, delivered by clinical psychologists who will be supervised.
