Enhancing Depression Literacy and Reducing Stigma in Adolescents Through Social Media

Depression is one of the most common mental disorders worldwide, with a prevalence of up to 7.5% in children and adolescents. In connection with the COVID-19 pandemic, a meta-analysis found an increase in clinically relevant depressive symptoms to 25.2% in children and adolescents. At the same time, adolescents who experience mental health crises are reluctant to seek help and only 12% of adolescents with clinically relevant depressive symptoms seek professional treatment. The main barriers for young people to seek professional help include low knowledge of mental disorders/low mental health literacy and social factors such as the fear of stigmatization. Mental health literacy (MHL) is defined as "how to prevent mental disorders, recognition of when a disorder is developing, knowledge of help-seeking options and treatment available, knowledge of effective self-help strategies for milder problems, and first aid skills to support others who are affected by mental health problems". It has been found that increased depression literacy can reduce depressive symptoms in adults and improve help-seeking for depression. Stigma in the context of mental health is a multidimensional concept that encompasses several domains. For many people living with mental illness, stigma is a significant contributor to a wide range of negative outcomes, including delayed help-seeking, hopelessness, diminished self-esteem, reduced quality of life and poorer clinical outcomes. Many of these negative effects have also been found in young people with mental health problems. Therefore, improving MHL and reducing the stigmatization of mental illness are two important starting points that can serve as targets for interventions. Improved MHL goes hand in hand with better knowledge about seeking help and less stigmatization of mental illness. The vast majority of adolescents in western countries, such as the US and Germany, have access to digital devices, such as smartphones, 97% of young people in the U.S. (13-17 years) state that they use social media and 45% say that they are online almost all the time. Along with this, young people are more likely to ask health questions, including mental health questions, online than through other channels. However, to date, few digital psychoeducational interventions for depression in adolescents have been developed and evaluated. In order to meet this need for action in a contemporary manner that attracts youth, the web-based project "ich bin alles" (English: "I am everything"; www.ich-bin-alles.de) was launched in September 2021 with an associated social media presence. The "ich bin alles" project provides comprehensive evidence-based and age-appropriate information on depression and mental health in youth via social media (such as Instagram). The aim of this study is to investigate in a randomized controlled trial whether educating adolescents via Instagram is an effective and accepted method to inform about depression and mental health. In more detail, the effects of targeted communication of content via Instagram on (1) information regarding the appearance, causes, and development of depression, (2) stigma towards depression, and (3) help-seeking behaviour are investigated. It is examined whether this communication of information leads to an increase in depression literacy, a reduction in stigma, and an increase in the intention to seek help and whether these changes are maintained over three months. Furthermore, the acceptance of the content will be investigated. In this study, participants will be randomly assigned to either an experimental group (EG) or an active control group (CG). Participants assigned to the EG will be asked to regularly consume "ich bin alles" Instagram content over the period of four weeks. The CG will be asked to regularly view content from an Instagram channel from the field of education created by a public broadcaster (https://www.instagram.com/terrax/) over the same time period. Before the reception of the content (pre), after four weeks (post), and at a three months follow-up, participants will fill out questionnaires via an app ("m-Path"), with each assessment lasting approx. 30 minutes. At each assessment point, participants simultaneously receive a push notification via the app to complete the questionnaire. The pre-assessment is intended to check the eligibility criteria and record demographic data such as gender, highest educational qualification, and current employment/education status. The primary outcome measures (depression literacy, intention to seek help, stigma) are assessed at pre, post, and follow-up. After 4 weeks, the post assessment will take place, during which acceptance is also tested in addition to the primary outcome measures. After another 3 months, the follow-up assessment is scheduled. During the four-week intervention period, Ecological Momentary Assessment will be used to ask adolescents a few short questions every day about their mood and their use of the Instagram channel via the m-Path app.
