Differential Diagnosis
Worry is a common feature of almost all anxiety disorders (e.g. social phobia, panic) as well as other disorders (e.g. hypochondriasis)
GAD dx:
Worry cannot be confined to features of another disorder
*e.g. worry about having a panic attack; worry about social situation, worry about contamination
GAD Comorbidity
93% of patients with GHD are diagnosed with at least one additional disorder
46% comorbid with major depression or dysthymia
*Estimates of 50% of alcohol abusers have prior dx of GAD
GAD prevalence
3.1% of US population (6.8 million individuals)
10% – sub-threshold GAD
“worriers”
Worry Functionality
Worry is an attempt at problem solving
Given the prevalence of worry, something so widespread must of had an adaptive function
*without worry, unable to anticipate potential negative events
Information Processing Model of Anxiety
Anxiety =
Appraisal of risk/danger
+
Appraisal of coping with the risk/danger
Psychopathology of GAD
Increased risk perception
Decreased coping ability
Increased risk perception
Information processing is driven by a core sense (schema) of vulnerability
Vulnerability leads to over estimation of risk
*both probability and severity
Decreased Coping Ability
Problem-solving is impaired, overrun by anxiety
Replaced by cognitive avoidance and safety seeking behaviors
Thus – perception of coping ability is decreased
GAD as Personality Disorder
- Lifelong and chronic history of anxiety with no clear onset, or onset stemming from childhood or adolescence
- Generalized anxiety (worry) is a very common feature of normal behavior
* it is a basic psychological dimension that is present in everyone to some degree
Treatment Implications of GAD as Personality Disorder
More chronic may mean more treatment required
Ego-syntonic – is there a motivation to change?
GAD evidence-based interventions
Cognitive Restructuring
Worry Exposure
Stimulus – Control Procedures
