300.02 Generalized Anxiety Disorder

Diagnostic Features-

The essential feature of Generalized Anxiety Disorder is excessive anxiety and worry (apprehensive expectation), occurring more days than not for a period of at least 6 months, about a number of events or activities (Criterion A). The individual finds it difficult to control the worry (Criterion B). The anxiety and worry are accompanied by at least three additional symptoms from a list that includes restlessness, being easily fatigued, difficulty concentrating, irritability, muscle tension, and disturbed sleep (only one additional symptom is required for children) (Criterion C). The focus of the anxiety and worry is not confirmed to features of another Axis I disorder such as having a Panic Attack (as in Panic Disorder), being embarrassed in public (as in Social Phobia), being contaminated (as in Obsessive Compulsive Disorder), being away from home or close relatives (as in Separation Anxiety Disorder), gaining weight (as in Anorexia Nervosa), having multiple physical complaints (as in Somatization Disorder), or having a serious illness (as in Hypochondriasis), and the anxiety and worry do not occur exclusively during Post-traumatic Stress Disorder (Criterion D). Although individuals with Generalized Anxiety Disorder may not always identify the worries as "excessive", they report subjective distress due to constant worry, have difficulty controlling the worry, or experience related impairment in social, occupational, or other important areas of functioning (Criterion E). The disturbance is not due to the direct physiological effects of a substance (i.e., a drug of abuse, a medication, or toxin exposure) or general medical condition and does not occur exclusively during a Mood Disorder, a Psychotic Disorder, or a Pervasive Developmental Disorder (Criterion F).

The intensity, duration, or frequency of the anxiety and worry is far out of proportion to the actual likelihood or impact of the feared event. The person finds it difficult to keep worrisome thoughts from interfering with attention to tasks at hand and has difficulty stopping the worry. Adults with Generalized Anxiety Disorder often worry about everyday, routine life circumstances such as such as possible job responsibilities, finances, the health of family members, misfortune to their children, or minor matters (such as household chores, car repairs, or being late for appointments). Children with Generalized Anxiety Disorder tend to worry excessively about their competence or the quality of their performance. During the course of the disorder, the focus of worry may shift from one concern to another.
