Behavioral Activation and Behavioral Inhibition Scales (BIS/BAS Scales)

This questionnaire assesses personality and behavior, and consists of two scales: The Behavioral Inhibition System (BIS) and the Behavioral Approach System (BAS) scale. The BIS scale is designed to measure individual differences in the tendency to experience negative emotions and to avoid threatening or aversive situations. The BAS scale is designed to measure individual differences in the tendency to approach and pursue positive goals and rewards. Research has shown that individual differences in BIS and BAS scores can be related to various aspects of well-being and mental health. For example, research has found that individuals who score higher on the BAS scale tend to have higher levels of well-being and are more likely to report positive affect and life satisfaction. On the other hand, individuals who score higher on the BIS scale tend to be more reactive to stress and may be more vulnerable to negative affect and mental health problems such as anxiety and depression.
