Abstract: This paper explores the effects of cognitive-behavioral therapy (CBT) on anxiety symptoms in patients with generalized anxiety disorder (GAD). A total of 50 participants were recruited and randomly assigned to either an experimental group receiving 12 sessions of CBT or a control group. Results showed that the experimental group had significant reductions in anxiety symptoms compared to the control group. These findings suggest that CBT can be an effective treatment for GAD patients.

Introduction: Generalized anxiety disorder (GAD) is a highly prevalent mental health condition characterized by excessive and uncontrollable worry. Cognitive-behavioral therapy (CBT) has been demonstrated as an effective treatment for anxiety disorders, including GAD. However, there is a need for further exploration of the effects of CBT on GAD symptoms.

Method: Participants were recruited through a mental health clinic and screened for inclusion criteria. A total of 50 participants were included in the study and randomly assigned to either an experimental group (n=25) receiving 12 weekly sessions of CBT or a control group (n=25). Participants completed self-report measures of anxiety symptoms at baseline and at the end of the intervention period.

Results: Analyses revealed significant reductions in anxiety symptoms in the experimental group compared to the control group (t=3.12, p<.05). There were no significant differences in anxiety symptoms between the groups at baseline (t=.56, p>.05).

Conclusion: The results of this study support the effectiveness of CBT as a treatment for anxiety symptoms in patients with GAD. Clinicians should consider CBT as a viable treatment option for their patients with GAD. Future research should investigate the long-term effects of CBT on GAD symptoms and explore potential moderators of treatment response.
