The Effectiveness of Psychological Interventions for Common Mental Disorders

"The psychotherapeutic treatment will reflect the therapy practices that characterize the Danish primary sector.~Treatment: Clients are referred by their GP to receive up to 12 individual psychotherapy sessions, typically of 50-60 minutes' duration. For clients with depression and anxiety as referral reason, it is possible to get a supplementary referral by the GP ensuring 12 more sessions, totaling 24 sessions of therapy.~Procedure: Due to the Danish primary sector having relative freedom in method of choice, the psychologist carries out the psychotherapy according to the treatment principles they consider the most relevant, without clauses regarding specific models of therapy or manualization. The therapists register the therapeutic approaches and interventions used in each course of therapy on The Multitheoretical List of Therapeutic Interventions (MULTI-30)at the end of each treatment."

"Treatment: During the waiting list period, clients will not receive any psychotherapeutic treatment for their mental health issues in the Danish primary sector. However, their general practitioner may refer them to appropriate psychiatric treatment if their mental condition worsens and requires immediate treatment.~Procedure: Clients in the waiting list group will fill in questionnaires on their symptom development during the waiting period. They will complete the same set of predictor and outcome questionnaires as the psychotherapy group."
