Which anxiety scale differentiates between state and trait anxiety? a. Penn State Worry Questionnaire (PSWQ) b. Beck Anxiety Inventory (BAI) c. State-Trait Anxiety Inventory (STAl) d. Social Phobia Inventory (SPIN)

The correct answer is c. State-Trait Anxiety Inventory (STAI).<br /><br />The State-Trait Anxiety Inventory (STAI) is a psychological assessment tool designed to differentiate between state anxiety and trait anxiety. State anxiety refers to the temporary emotional condition of anxiety, which can fluctuate depending on the situation. Trait anxiety, on the other hand, is a more stable and enduring characteristic of an individual, representing their general tendency to experience anxiety across various situations.<br /><br />The STAI consists of two main components: a state anxiety scale and a trait anxiety scale. The state anxiety scale measures the intensity of anxiety experienced in a specific situation at a particular moment, while the trait anxiety scale assesses the individual's general level of anxiety as a personality trait.<br /><br />By using the STAI, researchers and clinicians can gain insights into both the immediate anxiety experienced in specific situations (state anxiety) and the individual's overall predisposition to anxiety (trait anxiety). This differentiation is crucial for understanding and addressing anxiety-related issues effectively.
