Specific phobia

Specific phobia is the most circumscribed anxiety diagnosis, and the exam tests whether you keep it circumscribed: one feared object or situation, out-of-proportion fear, and exposure as the first-line treatment.

Criteria at exam depth. Marked fear or anxiety about a specific object or situation (flying, heights, animals, receiving an injection, seeing blood). The object or situation almost always provokes immediate fear, and it is actively avoided or endured with intense fear. The fear is out of proportion to the actual danger and sociocultural context, persists typically six months or more, and causes clinically significant distress or impairment. It is not better explained by another disorder (for example, avoidance in agoraphobia, trauma reminders in PTSD, obsessions in OCD, separation in separation anxiety disorder, social situations in social anxiety). In children, fear may appear as crying, tantrums, freezing or clinging. Specify the stimulus: animal, natural environment (heights, storms, water), blood-injection-injury, situational (airplanes, elevators, enclosed places), and other (such as choking or vomiting). Many clients have more than one.

Blood-injection-injury type is distinctive: instead of a sustained fight-or-flight response, many clients have a vasovagal reaction, with heart rate and blood pressure rising briefly and then dropping, which can cause fainting. Applied tension (tensing large muscles to raise blood pressure) is used with exposure for this type, and fear of medical procedures can lead clients to avoid needed care.

Hinge differentials.

• Agoraphobia: fear across two or more situation types because escape or help may be unavailable.
• Social anxiety disorder: fear is of evaluation, not of the object itself.
• PTSD: fear and avoidance tied to a traumatic event with intrusion and arousal symptoms.
• OCD: avoidance driven by obsessions (e.g., contamination).
• Separation anxiety disorder: fear centers on separation from attachment figures.
• Panic disorder: attacks are unexpected, not triggered only by the phobic cue.
• Developmentally normal fears: common in young children, transient and not impairing.

On the NCMHCE. The counselor assesses the specific stimulus, the avoidance pattern and its cost (missed medical care, career limits), and asks about fainting history before any exposure work. First-line treatment is exposure therapy: building a fear hierarchy and progressing through graded in vivo exposure, with imaginal or virtual reality exposure when in vivo is impractical; one-session treatment is an option for some phobias. Systematic desensitization pairs relaxation with the hierarchy. Medication is not first-line for specific phobia. Consider cultural meaning: some fears are culturally sanctioned and not out of proportion within that context.

Clinical Pearl: One circumscribed fear, out of proportion, six months, avoided or endured with dread; treat with graded exposure. Blood-injection-injury fear can cause fainting, so pair exposure with applied tension.
