Abstract
This investigation assessed of the ability of Reinforcement Sensitivity Theory (RST), comprising the Behavioral Activation System (BAS), and Behavioral Inhibition System (BIS) to predict perfectionism. A total of 508 community participants were acquired using MTurk and completed measures of personal standards and self-evaluative perfectionism, as well as BIS and BAS. Regression analyses revealed that BAS sensitivity successfully predicted personal standards perfectionism (and to a lesser extent self-evaluative perfectionism), while BIS sensitivity successfully predicted self-evaluative perfectionism (and to a lesser extent personal standards perfectionism). BAS and BIS were robust predictors in their respective regression models, suggesting that these important perfectionism factors are successfully and jointly predicted by the BAS/BIS pre-dispositional motivation constructs.
Highlights
Reinforcement sensitivity theory (RST) proposes that certain neuropsychological processes partially govern responses to environmental stimuli, forming the basis for individual personality dispositions [7, 11, 22]
The regression results indicated that Behavioral Activation System (BAS) Drive most positively predicts perfectionistic strivings perfectionism, suggesting that the more an individual displays a basic neuropsychological urge to strive for positivity with effort, the more likely they may be to display the achievement oriented, organized and planful high perfectionistic strivings perfectionism
BAS Funseeking may be counterproductive to perfectionistic strivings perfectionism, as the regression results indicate lower tendencies to spontaneously engage in momentary positive experience may be indicative of a higher perfectionistic strivings perfectionism
Summary
Reinforcement sensitivity theory (RST) proposes that certain neuropsychological processes partially govern responses to environmental stimuli, forming the basis for individual personality dispositions [7, 11, 22]. Perfectionism has been described as a multidimensional set of behaviors and beliefs, characterized by a personal strivings factor and by a self-evaluative concerns and worries factor [20]. Using the theory of RST to explain internal responses to the perception of reward and threat related to striving for excellence and flawlessness, the role of RST mechanisms in providing partial biological underpinnings to perfectionistic personality characteristics was investigated
