  1. Specific Phobia: Anxiety Disorder

  2. DSM-V Diagnostic Criteria • A. Marked fear or anxiety about a specific object or situation (in children the fear or anxiety may be expressed by crying, tantrums, freezing, or clinging) • B. The phobic object or situation almost always provokes immediate fear or anxiety • C. The phobic object or situation is actively avoided or endured with intense fear or anxiety • D. The fear or anxiety is out of proportion to the actual danger posed by the specific object or situation and to the sociocultural context

  3. DSM-V Diagnostic Criteria • E. The fear, anxiety or avoidance is persistent, typically lasting for 6 months or more • F. The fear, anxiety, or avoidance causes clinically significant distress or impairment in social, occupational, or other important areas of functioning • G. The disturbance is not better explained by the symptoms of another mental disorder, including fear, anxiety, and avoidance of situations associated with panic-like symptoms or other incapacitating symptoms (as in agoraphobia); objects or situations related to obsessions (as in OCD); reminders of traumatic events (as in PTSD); separation from home or attachment figures (as in SAD); or social situations (as in social anxiety disorder)

  4. Specify if… • The code assigned is based on the phobic stimulus: • Animal (spiders, insects, dogs) • Natural environment (heights, storms, water) • Blood-injection-injury (needles, invasive medical procedures) • Situational (airplanes, elevators, enclosed places) • Other (situations that may lead to choking or vomiting; in children, loud sounds or costumed characters)

  5. Diagnostic Features • Phobic stimulus • For diagnosis, response must be different from “normal, transient fears that commonly occur in the population” • Amount of fear/anxiety experienced may vary with proximity to the phobic stimulus • Fear/anxiety may happen in anticipation of or in presence of actual stimulus

  6. Diagnostic Features • Reaction may take form as a full or limited symptom panic attacks • Fear/anxiety evoked nearly every time contact is made with phobic stimulus • Fear/anxiety often expressed different in children and adults • Immediate rather than delayed reaction when in contact with phobic stimulus

  7. Diagnostic Features • Individual actively avoids phobic stimulus (intentionally behaves in ways that are designed to prevent/decrease contact with phobic stimulus) • Avoidance behaviors are obvious or less obvious • Physiological Arousal • Amygdala and related structures

  8. SP Prevalence • 12 month community prevalence estimate for US ~7-9% • European countries 6% • Asia, Africa, Latin American countries 2-4% • Children ~ 5% 13-17 year olds 16% • Older individuals 3-5% • Females > males, 2:1 (varies across phobic stimulus)

  9. Comorbidity • Unlikely to only present SP without other psychopathology • Frequently associated with range of disorders • Increased risk for developing other anxiety disorders, depression, bipolar, substance related disorders, somatic symptom and related disorders, and personality disorders (dependent personality disorder)

  10. Course of SP • SP can occur: after experiencing or observing a traumatic event, informational transmission, unexpected panic reaction in presence of soon to be phobic stimulus • Many individuals are unable to recall the reason for onset of SP • Onset usually in early childhood, majority of cases develop before age 10, (type of SP varies onset) • Early onset is usually associated with a wax and wane pattern

  11. Risk and Prognostic Factors • Temperamental: Negative affectivity (neuroticism), behavioral inhibition • Environmental: Parental over protectiveness, parental loss & separation, physical/sexual abuse, negative or traumatic event • Genetic/Physiological: First degree relative with SP, significantly more likely to have SAME SP, individuals with blood-injection-injury show unique propensity to fainting in presence of phobic stimulus • Culture: Asians and Latinos report significantly lower rates of SP/ countries outside of US show differences in disorder • Suicide: 60% more likely to make suicide attempt w/ SP diagnosis

  12. Differential Diagnosis • Agoraphobia: If individual fears only ONE of the agoraphobia situations- Specific Phobia-Situational • Social Anxiety Disorder: If situations are feared because of negative evaluation – SAD not SP • Separation Anxiety Disorder: If situations are feared because of separation from a primary caregiver or attachment figure- Separation Anxiety Disorder • Panic Disorder: If the panic attacks only occur in response to the specific phobia stimulus- Specific Phobia

  13. Differential Diagnosis • OCD: If fear or anxiety is result of obsessions and other diagnostic criteria are met- OCD • Trauma- and stressor-related disorder: If phobia develops after traumatic event, consider PTSD, only assign SP if ALL PTSD criteria are not met • Eating disorders: If avoidance behavior is exclusively limited to avoidance of food and food-related cues, anorexia nervosa or bulimia considered • Schizophrenia spectrum and other psychotic disorders: When fear/avoidance are due to delusional thinking- SP NOT WARRANTED

  14. DSM-V Model Experience or observation of traumatic event/information transmission/ situation Suicide Parental environment: protectiveness, separation, loss, physical or sexual abuse/ neglect Phobia Stimulus: Specific object or situation Comorbidity Genetic predisposition: First degree relative risk/ amygdala and related structures Specific phobia Temperamental: Negative affectivity Behavioral Inhibition

  15. Fears are Normal • Mild fears are fairly common among children (Craske, 1997) • Infancy: children become fearful of stimuli in their immediate environment (Muris, Merckelbach, de Jong & Ollendick, 2002) • As child develops, fears start to incorporate anticipatory events and stimuli of an imaginary or abstract nature (Muris et al., 2002) • This developmental pattern is assumed to reflect everyday experiences and mediated by cognitive capacities (Muris et al., 2002)

  16. Descriptives on SP (Essau, Conradt, & Petermann, 2000) • Examined the frequency, comorbidity, & psychosocial impairment of SP and specific fears • First wave of the Bremen Adolescent Study (BJS) (northern Germany) • How frequent in 12-17 yr olds • Distribution according to sex and age • Comorbidity of other disorders • Level of impairment
