Specific Phobia Questionnaire (SPQ)
Also known as: SPQ
The Specific Phobia Questionnaire (SPQ) is a brief self-report measure assessing fear, avoidance, and distress related to specific phobic objects or situations (e.g., heights, spiders, flying, blood-injection-injury). Developed by Osman and colleagues in the 1990s, the SPQ captures the cognitive, behavioral, and physiological dimensions of specific phobia in a concise format. It is useful in clinical screening, diagnosis, and treatment monitoring for diverse phobias.

When to use it
The SPQ is indicated for screening and assessing specific phobias across age groups (typically adolescents and adults). It is useful in pre-treatment evaluation to quantify phobic severity, constructing exposure hierarchies, monitoring response to cognitive-behavioral or exposure-based interventions, and research examining phobia mechanisms. Less suitable for children under 8 or those with severe cognitive impairment. Not appropriate for agoraphobia, social anxiety, or generalized anxiety—use disorder-specific measures for these.
Strengths & limitations
- Brief and easy to administer; rapidly assesses phobic fear, avoidance, and distress.
- Multidimensional structure captures cognitive, behavioral, and physiological facets of phobia.
- Sensitive to exposure therapy and systematic desensitization; reliably tracks improvement.
- Applicable to diverse phobias (heights, animals, blood-injection-injury, flying, water, etc.) with consistent psychometric performance.
- Directly informs exposure hierarchy construction based on subscale elevations and specific item content.
- Generic format means items may not precisely match a patient's unique phobic content (e.g., a person with fear of escalators may find generic 'heights' items less relevant).
- Does not assess functional impairment (e.g., missed work or social activities due to phobia); high scores must be contextualized with disability assessment.
- Modest test–retest reliability (r = 0.65–0.75) suggests state-level fluctuation, especially pre-exposure or in avoidance contexts.
- Does not distinguish between specific phobia subtypes (animal, natural environment, blood-injection-injury, situational); subtype-specific measures are more precise.
Frequently asked
How is a specific phobia different from normal fear?
Normal fear is adaptive, proportional to actual threat, and manageable via coping strategies. Phobic fear is intense, disproportionate, persists despite safety (the plane lands safely but fear returns), and drives avoidance that narrows life opportunities. A person with specific phobia often recognizes the fear as excessive yet feels unable to control it. SPQ scores 60+ typically indicate phobia rather than normative fear.
What is the most effective treatment for specific phobia?
Exposure therapy (systematic desensitization or in vivo exposure combined with response prevention—not escaping or using safety behaviors) is the gold standard. Cognitive-behavioral therapy adds cognitive restructuring and anxiety management skills. Virtual reality exposure is effective for some phobias (flying, heights). Pharmacotherapy (benzodiazepines) provides short-term relief but does not resolve the phobia.
Can I use SPQ for multiple phobias (e.g., both heights and flying)?
If multiple specific phobias exist, administer SPQ separately for each (or use modified versions with phobia-specific content). Treat them sequentially: start with the phobia causing greatest distress or functional impairment, then address others. Some patients experience 'mastery' from one exposure treatment (e.g., conquering flying) that facilitates approach to other phobias.
How long does exposure therapy take?
Specific phobias often respond rapidly to exposure. Many patients show 30–50% improvement in 4–8 weeks of weekly therapy. Some phobias (e.g., blood-injection-injury phobia, flying phobia) may respond in 1–2 intensive sessions. Maintenance work continues post-treatment (ongoing exposure to prevent relapse) for 3–12 months.
