Revised Reinforcement Sensitivity Theory: Implications for psychopathology and psychological health

We examined the utility of revised Reinforcement Sensitivity Theory (r-RST) in comparison with original Reinforcement Sensitivity Theory (o-RST) in further understanding psychopathology and well-being. In line with theory, we found o-BIS to be a non-specific predictor of anxiety and stress whereas r-BIS and r-FFFS scales were predictors of anxiety and stress. Consistent with the joint systems hypothesis, depression was associated with r-BIS, but only when r-BAS was low. The r-BAS, low o-BIS and low r-Freeze were the only predictors of psychological well-being. These findings suggest that r-BAS as we measured it reflects more functional approach behaviour than measures of o-BAS. Further, while o-BIS appears to be associated with broad negative affective states, the parsing of r-BIS from fear potentially provides r-RST with a more refined understanding of psychopathology and reduced well-being.
