Scale Analysis

The BIS/BAS (Behavioral Inhibition System/Behavioral Activation System) questionnaire is a tool used in psychology to measure an individual’s tendency to avoid or to be activated by different stimuli or situations. The BIS/BAS-24 consists of 24 items referring to three different subsystems.

Purpose

The purpose of this scale is to measure an individual’s tendency to react to threats, dangers, and negative situations (BIS), as well as the tendency to seek positive stimuli and opportunities for reward (BAS). Ongoing research applications of the questionnaire aim to understand the personality traits related to these systems and their impact on various aspects of behavior and psychological functioning. With its help, researchers and clinicians can better understand how different response tendencies affect an individual’s behavior and experience.

Scale Calibration

The BIS/BAS-24 scale consists of 24 items referring to three different subsystems:
Behavioral Inhibition System (BIS): This system is responsible for the perception of and reaction to threats, dangers, and negative situations. Individuals who score high on this system tend to be more cautious, anxious, and avoidant of risks.
Behavioral Activation System (BAS): This system is responsible for seeking and reacting to positive stimuli and opportunities for reward. Individuals who score high on this system tend to be more optimistic, adventurous, and reward-seeking.
