Abstract

This research was born from the purpose of developing and testing "Maya," a virtual assistant designed to support the early detection of Generalized Anxiety Disorder (GAD). In this context, we understood early detection not merely as a technical diagnosis, but as a vital opportunity to identify red flags and thought patterns before anxiety became overwhelming for the patient, thus creating a bridge toward professional help.

To bring this tool to life, we merged psychology and technology in a profound way. We integrated the foundations of Cognitive Behavioral Therapy (CBT) through dialogues that guided users in questioning their own thoughts, serving as a safe space for digital self-reflection. Furthermore, the ability of GPT-3.5 models to identify symptoms was no mere coincidence; it was based on a semantic analysis logic capable of recognizing the "language of anxiety." The model successfully interpreted specific linguistic markers, such as constant rumination and the tendency to imagine catastrophic scenarios, translating these natural expressions into clear clinical indicators.

The evaluation process was a shared experience between technology, a clinical psychology expert, and 50 individuals who interacted with the assistant. The results were deeply human: the System Usability Scale (SUS) reached 84%, reflecting an excellent reception. Most importantly, 96% of users felt their symptoms were understood with accuracy, while 98% found comfort and guidance in the suggested coping strategies. ultimately, "Maya" proved to be a warm and accessible support resource, focused on emotional education and preventive triage, always aiming to complement the specialist's work, never to replace it.
