Psychological Therapy for Gaming Disorder

Gaming is a common leisure activity, both for children and adult, and while it is generally a positive experience for most, it can lead to problems for some individuals. There is currently a lack of knowledge of when video gaming becomes a problem and why, and there is a lack of evidence-based interventions for treating Gaming disorder. This pilot study aims to evaluate a new treatment manual for Gaming Disorder, which consists of modules based on cognitive behavioral therapy and family therapy. The therapy can be provided as individual therapy to the patient, to relatives, or as family therapy involving both the patient and their relatives. This study is an effectiveness trials and will follow all-patients at the clinic who will be offered the treatment.

The hypothesis is that the manual-based psychotherapy for Gaming Disorder will result in a reduction of Gaming Disorder symptoms and psychological distress, as well as an improvement in daily functioning.

About this study

This study is a part of the clinical work at Gamingprojektet Maria Malmö, which is an outpatient clinic for patients with problematic gaming or Gaming Disorder. The clinic is focused on young people over 13 years of age and adults with problematic gaming or who meet the diagnosis of Gaming Disorder.

The study will aim to evaluate a new treatment that has been developed and are offered at Gamingprojektet Maria Malmö for patients with a problematic gaming behavior or Gaming Disorder. Before starting the treatment, they will undergo a semi-structured interview about their gaming habits, motivation for playing, demographic information, gambling, social habits, family climate, physical health, and psychiatric comorbidity. This is combined with self-assessment questionnaires on mental health, social media habits, alcohol use, drug use, gambling, emotion regulation, and everyday functioning. They will be offered a psychological treatment that combines Cognitive behavioral therapy (CBT) and Family therapy (FT). At each session, they will answer short questions about their well-being, how much they have played in the past week, and how much their well-being is related to their gaming. After completing the treatment, the patients will undergo the same semi-structured interview and questionnaires as pre-treatment. Three months after the treatment has ended, they will be called for a follow-up, where they will complete questioners about symptoms of Gaming disorder and psychological wellbeing. The study is conducted fully integrated into regular clinical practice, which allows for the feasibility and possibilities for implementation to be studied directly in connection with the study and in relation to treatment outcomes.
