Generalized anxiety disorder (GAD) is a common, chronic disorder. Cognitive behavioral therapies, including acceptance-based behavior therapy, have been found to be effective; however, many people do not receive or persist in treatment. Barriers to treatment for GAD include shame and stigma about symptoms, lack of access to quality information about GAD and treatment, logistics (e.g., cost and time), positive beliefs about symptoms (e.g., my worry is helpful), and contextual, systemic, and cultural factors (e.g., racism-related stress and other forms of discrimination). While some of these barriers need to be addressed at the systemic level, we provide specific recommendations for clinicians to increase engagement in treatment for people with GAD, including collaborative case formulation, developing a strong culturally responsive therapeutic alliance, values clarification, addressing situational and contextual stressors in treatment, cultural adaptations, and flexibility in treatment to address stigma, avoidance, unrealistic expectations for therapy, fear of uncertainty, and sociocultural barriers to engagement.
