Social Phobia Inventory

Overview

The Social Phobia Inventory (SPIN) is a 17-item self-rated scale specifically designed to assess social anxiety disorder (social phobia) in adolescents and adults. It evaluates three primary domains of the disorder: fear, avoidance, and physiological arousal experienced in social or performance situations over the past week.

Developed to address the need for an efficient and valid screening tool, the SPIN has proven itself through robust psychometric properties. Research shows it effectively distinguishes between individuals with and without social phobia, accurately measures symptom severity, and is sensitive to changes in symptoms over time. It demonstrates good test-retest reliability and internal consistency, ensuring consistent and cohesive measurement of social anxiety.

The SPIN's design facilitates ease of use in clinical and research settings, allowing for self-administration and making it accessible for various applications. It correlates well with other established measures of social anxiety, supporting its validity, and has been instrumental in understanding prevalence, severity, and treatment outcomes of social anxiety disorder.

Its practicality extends to monitoring treatment progress, providing clinicians and researchers with a comprehensive tool to assess the impact of social anxiety on individuals' daily lives. Widely adopted due to its reliability and utility, the SPIN continues to play a crucial role in both diagnosing social anxiety disorder and advancing research in mental health.
