State-Trait Anxiety Inventory (STAI): A Comprehensive Anxiety Assessment Tool

The State-Trait Anxiety Inventory (STAI) is a widely used and extensively validated self-report questionnaire, commonly employed in both research studies and clinical assessments. It effectively assesses both state anxiety (SAI) and trait anxiety (TAI). The STAI consists of two scales: SAI measures temporary anxiety experienced at a specific moment, while TAI measures general anxiety tendencies. Each scale consists of 20 items scored on a 4-point scale, with higher scores indicating higher levels of anxiety. The STAI provides reliable and valuable insights into anxiety levels among individuals aged 18 and older, offering a comprehensive assessment tool in various professional settings.
