2. Supportive resource priming: The supportive resource priming condition has the very same protocol as the resource priming condition (5 brief tandem peer tutorings). The only difference in the procedure is that the therapists are allowed to integrate a helpful significant person of the patients (such as the partners or the best friends) around session 1 and 7 to encourage and support the patient to realize their treatment plans (active integration of interpersonal resources). However, the integration of a significant other person does not touch the CBT-treatment protocol.
