Conditions

Generalized Anxiety Disorder

Brief summary

The purpose of this study is to determine whether acceptance-based behavior therapy for GAD results in greater symptom reduction and increased quality of life than applied relaxation.

Interventions

16 individual psychotherapy sessions focused on psychoeducation about anxiety, anxious responding, the function of emotions, mindfulness, and problems with efforts to constrict one's emotional experience; training in mindfulness skills; practice applying mindfulness skills in daily life, including acceptance of, rather than efforts to control, internal experience; and identification of values in areas of life and practice engaging in chosen actions.

16 sessions of individual psychotherapy focused on psychoeducation about anxiety and anxious responding; training in multiple forms of relaxation; early cue detection; and practice applying relaxation in daily life.
