Summary
Mobile cognitive behavioral therapy (CBT) is a cost-saving treatment for generalized anxiety disorder (GAD), improving health outcomes and reducing costs compared to traditional CBT or no intervention.
Area of Science:
- Mental Health Economics
- Digital Health Interventions
- Anxiety Disorder Treatment
Background:
- Generalized anxiety disorder (GAD) affects 3.1% of U.S. adults and is treatable with cognitive behavioral therapy (CBT).
- Digital health technologies offer potential for cost-effective GAD care delivery.
- Mobile CBT presents a novel approach to accessible mental healthcare.
Purpose of the Study:
- To develop an analysis framework for quantifying the cost-effectiveness of internet-based CBT for GAD.
- To evaluate the potential value of a new mobile-delivered CBT program for GAD through a case study.
Main Methods:
- A Markov model simulating GAD health states was developed for economic analysis.
- The study compared mobile CBT (prevention or treatment) against traditional CBT and no CBT using pilot efficacy data.
- Discounted incremental costs and quality-adjusted life-years (QALYs) were calculated over a cohort lifetime.
Main Results:
- Mobile CBT was found to be cost-saving for a cohort of 100,000 individuals with GAD.
- It resulted in significant QALY gains and substantial cost reductions compared to traditional CBT and no CBT.
- Results demonstrated robustness, with mobile CBT remaining cost-saving across most scenarios.
Conclusions:
- Mobile CBT offers a promising strategy for improving health outcomes and reducing healthcare costs for GAD.
- It may be effective as both a preventative measure and a treatment intervention.
- Further analysis with robust efficacy data is recommended, particularly regarding combination therapy with pharmacotherapy.

Generalized Anxiety Disorder (GAD) is a chronic condition characterized by excessive and uncontrollable worry that persists for at least six months, significantly interfering with daily functioning. Unlike situational anxiety, which arises in response to specific stressors, GAD often occurs without a clear cause. Individuals may experience disproportionate worry about work, health, or relationships. For instance, a person might continuously fear poor health despite normal medical evaluations or...

Social anxiety disorder, also known as social phobia, is characterized by an intense fear of social situations where one might face humiliation, rejection, embarrassment, or negative evaluation. This disorder leads individuals to avoid activities like casual conversations, public speaking, or seemingly simple tasks such as eating, signing documents, or swimming, in public settings. Its impact extends beyond discomfort, often significantly interfering with daily functioning and quality of life.

Cognitive therapy, pioneered by Aaron T. Beck in the 1960s, is a structured approach to addressing psychological distress by focusing on the influence of thoughts on emotions and behaviors. All cognitive therapies involve the basic assumption that human beings have control over their feelings, and that how individuals feel about something depends on how they think about it. Unlike psychoanalytic methods that delve into unconscious processes or humanistic approaches emphasizing...

Social psychology examines the complex interplay between individual mental processes and social interactions. Historically, the field was divided into two domains: social behavior and social cognition. Researchers focusing on social behavior analyzed actions within social contexts, such as conformity, aggression, or cooperation. Meanwhile, social cognition researchers investigated how people perceive, interpret, and mentally represent their social environments. However, modern perspectives no...

Behavior therapy incorporates diverse techniques rooted in classical conditioning principles to address maladaptive behaviors and anxiety disorders. These methods aim to reduce avoidance behaviors, foster adaptive coping mechanisms, and alter associations between stimuli and responses, making them effective in a wide range of therapeutic contexts.
