This article presents a theoretical and practical intervention aimed at demonstrating the intervention process from Cognitive-Behavioral Therapy, through a clinical case study of a 36-year-old patient whose reason for consultation was suffering a panic attack, because of her Generalized Anxiety Disorder.In the development of the evaluative process, a variety of tools were used, including semi-structured interviews, the IDARE questionnaire, the YSQ, and therapeutic activities.A treatment plan was designed, which focused on a group of techniques and tasks that allowed to show that cognitive-behavioral therapy was effective in reducing the patient's initial distress as the initial symptoms decreased, confidence increased, and more adaptive coping strategies were acquired, improving her interpersonal relationships.josha.org
