#### Title: The Effects of Acceptance and Commitment Therapy on Anxiety Symptoms in Generalized Anxiety Disorder: A Randomized Control Trial

Anxiety disorders are one of the most prevalent mental health issues worldwide, with Generalized Anxiety Disorder (GAD) being particularly challenging due to its chronic and pervasive nature. In recent years, Acceptance and Commitment Therapy (ACT) has emerged as a promising approach for treating anxiety by focusing on acceptance of internal experiences and commitment to valued actions. This study aimed to investigate the impact of ACT on anxiety symptoms in individuals diagnosed with GAD.

Participants were randomly assigned to either the ACT group or a control group receiving standard treatment for anxiety. The ACT group received 10 weekly sessions of individual therapy based on the core principles of ACT, while the control group received traditional cognitive-behavioral therapy. Anxiety symptoms were assessed before and after the intervention using standardized self-report measures.

Results revealed a significant decrease in anxiety symptoms in the ACT group compared to the control group. Participants in the ACT group reported greater acceptance of their anxious thoughts and feelings, as well as increased willingness to engage in meaningful activities despite anxiety-related discomfort. These changes were associated with improvements in overall psychological well-being and quality of life.

The findings of this study support the efficacy of ACT in reducing anxiety symptoms in individuals with GAD. The emphasis on acceptance and values-based action in ACT appears to provide a unique and effective approach to managing anxiety. Clinicians working with individuals with GAD may consider incorporating ACT techniques into their practice to enhance treatment outcomes.

#### Conclusion:

In conclusion, Acceptance and Commitment Therapy shows promise as an effective intervention for reducing anxiety symptoms in individuals with Generalized Anxiety Disorder. The focus on acceptance, mindfulness, and values-based action in ACT can lead to significant improvements in psychological well-being and quality of life. Further research is needed to explore the long-term effects of ACT on anxiety and to compare its efficacy with other established treatments for anxiety disorders.
