Teletherapy vs. In-Person Cognitive Behavioral Therapy for Generalized Anxiety Disorder

The goal of this randomized controlled trial is to compare the clinical efficacy of teletherapy versus in-person third-wave cognitive behavioral therapy (CBT) in treating generalized anxiety disorder (GAD) among young individuals aged 18-45 years in Pakistan. The main questions it aims to answer are: * Is teletherapy as effective as in-person therapy in reducing anxiety symptoms and stress? * Do therapeutic alliance, treatment adherence, and social support influence treatment outcomes differently across delivery methods? Researchers will compare the teletherapy group (remote sessions via digital platforms) and the in-person therapy group (face-to-face sessions) to evaluate differences in symptom reduction, general health improvement, and moderating factors like therapeutic alliance. Participants will: * Undergo a 8-week intervention with weekly structured third-wave CBT sessions. * Complete assessments at baseline, post-intervention, and follow-up using validated scales (e.g., Generalized Anxiety Disorder-7 \[GAD-7\], Hamilton Anxiety Rating Scale \[HAM-A\]). * Engage in modules including mindfulness, behavioral activation, and exposure therapy, adapted for their assigned delivery method. This study aims to address gaps in mental health accessibility in Pakistan by evaluating whether teletherapy can serve as a viable alternative to traditional in-person care.
