What This Measures
Two fundamental motivational systems shape how you approach the world:
BIS (Behavioral Inhibition System) — Makes you pause, scan for danger, and proceed with caution. Sensitive to punishment and threat cues.
BAS (Behavioral Activation System) — Pushes you toward goals, rewards, and opportunities. Sensitive to positive signals.
Everyone has different sensitivities in these systems. Some people have a stronger BIS (more cautious, prone to worry), others a stronger BAS (more impulsive, reward-driven).
Carver & White developed the BIS/BAS scales in 1994 to measure these two motivational systems. Researchers have used them extensively in psychology studies.
Dimensions
- BIS (7 items) — Sensitivity to threat, punishment, and negative outcomes
- BAS Drive (4 items) — Goal pursuit intensity and persistence
- BAS Fun Seeking (4 items) — Desire for novelty and immediate rewards
- BAS Reward Responsiveness (5 items) — Emotional reactivity to positive events
Scoring
Each item uses a 4-point scale (1=very true, 4=very false). Items 2 and 22 are not reverse-scored; all others are reverse-scored (5 - raw). Each dimension score is the mean of its items (range 1-4).
