What is the BAS and BIS scale?
According to this theory, there are two conceptually different models of motivational behavior:
BIS (behavioural inhibition system) - behavior is based on the desire to avoid punishment, to avoid unpleasant experience. High scores for the BIS scale mean increased sensitivity, fear of new experiences, a tendency to depression, anxiety and sadness.
BAS (behavioral approach system) - behavior is based on the desire for constant encouragement, rewards. People with high BAS scores are more physically and socially active, open to new experiences. Low BAS sensitivity is associated with introversion and depression.
At the same time, high BAS scores are highly correlated with risky health behaviors, including sexual activity, and addictive behaviours such as alcohol and drug use.
Online version of the Carver and White's BIS/BAS Scales
In order to measure the sensitivity to punishment and reward constructs, Carver and White developed a 24-item self-report BIS/BAS questionnaire.
