Mental Health INtervention With Digital APPlications (MIND-APP): Randomized Controlled Researcher Blinded Trial Evaluating the Effectiveness of the Tankevirus and Grubl Mental Health Apps (MIND-APP)

1 juni 2026 bijgewerkt door: Kim Rand, University Hospital, Akershus

App-Based Mental Health Interventions for Anxiety and Depression: Protocol for the MIND-APP Randomized Controlled Trial

The MIND-APP trial is a 3-arm randomized controlled trial (1:1:1 allocation) conducted fully remotely via a bespoke smartphone research platform. A total of 1000 Norwegian residents aged 16 years or older with mild to moderate symptoms of anxiety and/or depression will be recruited through national digital outreach. Coprimary outcomes are changes in anxiety (Generalized Anxiety Disorder-7) and depression (Patient Health Questionnaire-9) scores from baseline to postintervention (2-4 weeks). Secondary outcomes include health-related quality of life (EQ-5D-5L), quality-adjusted life years accrued over 6 months, functional impairment (Work and Social Adjustment Scale), health care resource use, and adverse events. Incremental cost-effectiveness ratios for Tankevirus and Grubl relative to placebo will be estimated from the perspective of public health services.

Placebo-vergelijker: Placebo app
The placebo / sham app will have structural elements largely matching Tankevirus and Grubl; providing a programme of approximately 2 weeks. The app will present information on attention control training as a method for reducing problems with anxiety and depression. While attention control training can be effective for this purpose, the app will only provide very brief (a few minutes) of daily attention-demanding miniature games, that are expected to have zero or negligible impact on anxiety or depression. Full details on the placebo arm setup including screenshots etc. will be provided alongside the registered report publication.

Tijdsspanne
The difference in GAD-7 score for anxiety symptoms between baseline and post-intervention for participants with mild to moderately severe self-reported problems with anxiety at baseline (GAD-7 score => 5)
Tijdsspanne: From baseline (first day) until first post-intervention measurement (approximately 2 weeks)
The Generalized Anxiety Disorder-7 (GAD-7) is a 7-item self-report scale developed to assess the severity of generalized anxiety disorder symptoms. It is widely used as a brief screening and outcome measure for anxiety in clinical practice and research. Measured at baseline, postintervention, and at 3- and 6-month follow-up. Items are scored 0 to 3 (total score 0 to 21). Cutoffs: 5 (mild), 10 (moderate), and 15 (severe). Change measured in participants reporting at least mild problems at baseline (GAD-7 >= 5).
From baseline (first day) until first post-intervention measurement (approximately 2 weeks)
The difference in PHQ-9 score for depression symptoms between baseline and post-intervention for participants with mild to moderately severe self-reported problems with anxiety at baseline (PHQ-9 score => 5)
Tijdsspanne: From baseline (first day) until first post-intervention follow-up (approximately 14 days)
The Patient Health Questionnaire-9 (PHQ-9) is a 9-item self-report instrument designed to assess depressive symptom severity based on Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria. It is a commonly used tool for depression screening and monitoring treatment outcomes in research and practice. Items are scored 0 to 3 (total score 0 to 27). Cutoffs: 5 (mild), 10 (moderate), 15 (moderately severe), and 20 (severe). Measured at baseline, postintervention, and at 3- and 6-month follow-up.

QALY accrual as measured using the EQ-5D-5L
Tijdsspanne: From baseline to 6 month follow up, linear interpolation
The EQ-5D-5L, developed by the EuroQol Group, measures HRQoL across 5 domains (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) with 5 severity levels. It is extensively used in clinical trials, health economics, and QALY calculations. The Norwegian EQ-5D-5L tariff will be used. Delta QALYs will be calculated using interpolation over the 6-month observation period. Utility values for QALY calculation will use the Norwegian EQ-5D-5L value set. Measured at baseline, postintervention, and at 3- and 6-month follow-up.
From baseline to 6 month follow up, linear interpolation
Change in functional impairment as measured using the WSAS
Tijdsspanne: Baseline to post-treatment, 3 months, 6 months
The Work and Social Adjustment Scale (WSAS) is a 5-item self-report scale developed to measure functional impairment attributable to a specific health problem across work, home management, social and private leisure activities, and relationships. It is frequently used to quantify disability in mental health research and evaluate treatment impact. Scores range from 0 to 40; higher scores indicate greater impairment. A score >20 indicates moderately severe or worse impairment. Measured at baseline, postintervention, and at 3- and 6-month follow-up.
