Mapping Gray’s BIS and BAS constructs onto Factor 1 and Factor 2 of Hare’s Psychopathy Checklist – Revised

Reinforcement sensitivity theory (RST; Gray, 1987; Gray & McNaughton, 2000) has proven to be a valuable tool for understanding psychopathy (e.g., Fowles, 1980, 1988; Newman & Malterer, 2009; Poythress et al., 2008). Recent research has linked two RST constructs, the Behavioral Inhibition System (BIS) and the Behavioral Activation System (BAS), to individuals with primary psychopathy and secondary psychopathy (Lykken, 1995; Newman, MacCoon, Vaughn, & Sadeh, 2005): Primary psychopaths manifest low BIS reactivity and secondary psychopaths manifest high BAS reactivity. In the present study, we examine the relationships between the BIS/BAS constructs and Factors 1 and 2 of the Psychopathy Checklist – Revised (PCL-R) in a sample of 472 incarcerated male offenders. Paralleling their relationships with primary and secondary psychopathy, the BIS/BAS constructs were differentially related to the two PCL-R factors. Specifically, the influence of the BIS was found to be more prominent than the influence of the BAS for Factor 1, and the influence of the BAS was more prominent than that of the BIS for Factor 2.     

Throwing more light on the dark side of psychopathy: An extension of previous findings for the revised Reinforcement Sensitivity Theory

Despite previous studies of psychopathy and the motivational systems of the Reinforcement Sensitivity Theory (RST) of personality, few have examined psychopathy in light of the revised RST model. In a large sample (N = 779) of young adults, we expand on Hughes, Moore, Morris, and Corr’s (2012) preliminary findings relating primary/secondary psychopathy to revised RST’s three systems: Flight-Flight-Freeze System (FFFS), Behavioral Inhibition System (BIS), and Behavioral Approach System (BAS). Converging results between Hughes et al. and the current study emphasize three major findings: (1) primary psychopathy is negatively related to the BIS as well as the FFFS; (2) primary psychopathy is positively related to goal-driven behavior of the BAS; and, (3) secondary psychopathy is positively related to impulsivity reflected in the BAS. The FFFS was incrementally predictive of primary but not secondary psychopathy. No evidence for a BAS × BIS interaction in psychopathy was found. Results are discussed in terms of future research directions.     

Coping mediates relationships between reinforcement sensitivity and symptoms of psychopathology

Limited research has evaluated whether coping strategies mediate the relationships between reinforcement sensitivity theory (RST) and symptoms of psychopathology. Undergraduates (n = 293) completed questionnaires assessing RST, coping, and symptoms of psychopathology. Consistent with our hypotheses, bootstrapping analyses indicated that emotion- and avoidance-focused coping mediated the relationship between high Behavioral Inhibition System (BIS) and depression, anxiety, and worry. Less problem-focused coping mediated the relationship between low Behavioral Approach System (BAS) and depression. Avoidance-focused coping mediated the effects of high BIS on drug and alcohol use whereas high BAS directly predicted alcohol and drug use. Unexpectedly, emotion-focused coping mediated the relationship between BAS and anxiety and worry. These results provide support for the hypothesis that personality variables are associated with psychopathology partially through coping.     

Throwing light on the dark side of personality: Reinforcement sensitivity theory and primary/secondary psychopathy in a student population

In a student sample, we examined two major issues in relation to primary/secondary subtypes of psychopathy and the reinforcement sensitivity theory of personality: the roles played by (a) fear (related to the fight-flight-freeze system, FFFS) and anxiety (related to the behavioural inhibition system, BIS), and (b) different aspects of the behavioural approach system (BAS). Largely consistent with Corr’s (2010a) proposal concerning the neuropsychological deficits associated with the psychoticism-psychopathy continuum, results confirmed that low BIS activity was associated with both primary and secondary psychopathy; whereas low FFFS activity was associated with only primary psychopathy. In relation to the BAS, reward sensitivity and drive were positively related to primary psychopathy; whereas Fun Seeking was negatively related to primary psychopathy but positively related to secondary psychopathy. These results represent a more nuanced picture of FFFS/BIS/BAS and dispositional psychopathy in a student sample. Specifically, they challenge the view that low BIS is preferentially associated with primary psychopathy and a high BAS is preferentially associated with secondary psychopathy. Further work is needed to confirm that these findings extend to clinical and forensic psychopathy populations.     

Modification of the startle reflex in a community sample: do one or two dimensions of psychopathy underlie emotional processing?

Recent research on psychopathy has begun to explore two dimensions that possibly underlie psychopathy–one related more to emotional and interpersonal traits, and another related more to antisocial behaviors. A community sample of adults was assessed for psychopathy using Hare's (1991) Psychopathy Checklist-Revised (PCL-R). Eyeblinks elicited by startle probes were recorded while participants viewed pictures of emotionally-laden stimuli. Consistent with previous research, participants scoring high on PCL-R Factor 2 (“antisocial”) showed no affective modification of startle if they also scored high on PCL-R Factor 1 (“emotional detachment”). When the factor scores were analyzed together as continuous variables in a regression analysis, however, affective modification of startle was negatively related to Factor 1 but positively related to Factor 2. The results thus provide further support for a two-factor model of psychopathy.     

Emotion dysregulation as a partial mediator between reinforcement sensitivity and posttraumatic stress symptoms

The reinforcement sensitivity theory (RST) asserts that three brain subsystems (i.e., the Behavioral Approach System [BAS], the Behavioral Inhibition System [BIS], and the Fight–Flight–Freeze System [FFFS]) underlie individual variations seen in personality and psychopathology. Though revised by Gray and McNaughton (2000), many researchers continue to utilize the original, and now outdated, theory of reinforcement sensitivity. Additionally, while there is an abundance of research investigating the association between reinforcement sensitivity and psychopathology, the underlying mechanisms between these constructs remain largely unknown. Therefore, the aim of the current study was to test whether emotion dysregulation acted as a partial mediator between FFFS sensitivity and posttraumatic stress symptoms (PTSS) under the revised RST framework. Data was collected from 282 undergraduate students at a Midwestern university who experienced at least one potentially traumatic event. Bootstrapping was used to test the significance of the indirect effect (e.g., amount of mediation) of FFFS sensitivity on PTSS. The indirect effect was significant (2000 bootstrapped CI_95 = .11−.25), indicating that emotion dysregulation partially mediated the relationship between FFFS sensitivity and PTSS. More specifically, individuals with high FFFS sensitivity reported higher levels of emotion dysregulation, which in turn was associated with greater PTSS scores.     

An evaluation of the relationship between Gray’s revised RST and Eysenck’s PEN: Distinguishing BIS and FFFS in Carver and White’s BIS/BAS scales

Recent revisions of Gray’s reinforcement sensitivity theory (RST) have important implications for self-report measures of approach and avoidance behaviours and how Gray’s model relates to other personality models. In this paper, we examine the revised RST by comparing Carver and White’s (1994) original one-factor solution of the BIS scale with two alternative two-factor solutions separating BIS-Anxiety and FFFS-Fear. We also examine the relationships between Eysenck’s PEN and revised RST factors. Two hundred and twelve participants completed Carver and White’s BIS/BAS scales and Eysenck’s Personality Questionnaire-Revised. Confirmatory factor analyses of the original BIS scale showed that the hypothesized two-factor model of BIS-Anxiety and FFFS-Fear was the best fit to these data. Associations between the revised RST and Eysenck’s PEN were examined using path analysis. In line with theoretical predictions, Psychoticism was related to revised BIS-Anxiety and BAS, Neuroticism to revised BIS-Anxiety and FFFS-Fear, and extraversion to BAS and FFFS-Fear. Distinctions between BAS subscales and their associations to BIS, N and P were made in terms of past, present and future focus. Possible explanations for mixed findings in the literature and implications for future research are discussed.     

Distinguishing between learning and motivation in behavioral tests of the reinforcement sensitivity theory of personality

According to Gray's (1973) Reinforcement Sensitivity Theory (RST), a Behavioral Inhibition System (BIS) and a Behavioral Activation System (BAS) mediate effects of goal conflict and reward on behavior. BIS functioning has been linked with individual differences in trait anxiety and BAS functioning with individual differences in trait impulsivity. In this article, it is argued that behavioral outputs of the BIS and BAS can be distinguished in terms of learning and motivation processes and that these can be operationalized using the Signal Detection Theory measures of response-sensitivity and response-bias. In Experiment 1, two measures of BIS-reactivity predicted increased response-sensitivity under goal conflict, whereas one measure of BAS-reactivity predicted increased response-sensitivity under reward. In Experiment 2, two measures of BIS-reactivity predicted response-bias under goal conflict, whereas a measure of BAS-reactivity predicted motivation response-bias under reward. In both experiments, impulsivity measures did not predict criteria for BAS-reactivity as traditionally predicted by RST.     

BIS,BAS, and response conflict: Testing predictions of the revised reinforcement sensitivity theory

Gray’s (1970) reinforcement sensitivity theory (RST) was recently updated (Gray & McNaughton, 2000), but the changes have not received extensive empirical validation. The study tests three novel predictions of the revised RST. First, the behavioral activation system (BAS) is expected to be sensitive to both conditioned and unconditioned incentives. Second, the behavioral inhibition system (BIS) is expected to be sensitive to conflicting incentives such as between unconditioned and conditioned stimuli, and not to avoidance responses or aversive stimuli alone. Third, during approach-avoidance conflicts only, BAS is expected to moderate BIS responses to conflict such that individuals with high BAS show the strongest effect of BIS. In order to test these hypotheses, we developed a novel incentive task that crosses approach/avoidance conditioned responses to appetitive/aversive unconditioned stimuli. Conflict between unconditioned and conditioned stimuli occurred on the approach-aversive and avoid-appetitive trials. Results confirm the predictions and provide support for the revised RST.     

Psychometric Evaluation and Revision of Carver and White's BIS/BAS Scales in a Diverse Sample of Young Adults

The psychometric properties of the Behavioral Inhibition System and Behavioral Activation System (BIS/BAS) scales (Carver & White, 1994) were evaluated in a large, racially diverse sample of undergraduate students. Findings from this study indicate that the BIS/BAS scales work differently (i.e., are multidimensional and lack configural invariance) when assessing BIS and BAS in a diverse sample. Numerous model modifications were needed to obtain adequate fitting models for the total sample and individual racial groups. The findings suggest that this is due to items that assess multiple constructs differently across self-reported race categories. As part of this research, a revised version of the BIS/BAS scales was constructed that appears to be invariant across self-reported race category and simultaneously addresses the other psychometric concerns associated with the original scale. Caution should be used when applying the BIS/BAS scales as originally specified to assess behavioral inhibition and activation in a racially diverse sample. Researchers might want to use this revised version of the scale as an alternative.     

The effects of behavioral inhibition/approach system as predictors of Internet addiction in adolescents

This study aimed to determine how the Behavioral Inhibition System (BIS) and the Behavioral Approach System (BAS) affect Internet addiction in adolescents. Two hundred and eleven high school students participated in this study and completed the Young’s Internet Addiction Test (IAT), BIS/BAS scales, and several self-administered questionnaires about depression, anxiety, and impulsivity. Hierarchical regressions showed that BIS and BAS × BIS emerged as significant predictors of IAT; however, only BAS-fun seeking subscale predicted IAT among BAS related subscales. In further analyses, the BAS-fun seeking subscale was mediated by impulsivity and anxiety, and BIS was mediated by anxiety and depression. The current findings imply that BIS and BAS interdependently influence vulnerability to Internet addiction through both shared (anxiety) and different (depression and impulsivity, respectively) pathways.     

Gray's Reinforcement Sensitivity Model and Child Psychopathology: Laboratory and Questionnaire Assessment of the BAS and BIS

The Behavioral Approach System (BAS) and Behavioral Inhibition System (BIS) are widely studied components of Gray's sensitivity to reinforcement model. There is growing interest in integrating the BAS and BIS into models of risk for psychopathology, however, few measures assess BAS and BIS functioning in children. We adapted a questionnaire measure and reaction time task from adult studies to assess the BAS and BIS in a sample of 9-12 year olds (N = 63; 42% female). A continuous performance task was also administered to assess physiological correlates of the BAS and BIS. Factor analysis supported 3 subdimensions of the BAS (Drive, Reward Responsivity, and Impulsivity/Fun seeking), and one dimension of the BIS (sensitivity to punishment). Results supported the utility of the questionnaire measures and reaction time task as assessments of BAS and BIS functioning. Moreover, these measures were associated with internalizing and externalizing problem behavior as expected. High levels of impulsivity/fun seeking, but not drive or reward responsivity, were associated with high levels of externalizing problems, whereas high levels of sensitivity to punishment were associated with high levels of internalizing behavior problems. The relation between physiological indices and caregiver reports of the BAS, BIS, and problem behavior were complex and not consistent with expectation.     

Responsiveness to Threat and Incentive in Bipolar Disorder: Relations of the BIS/BAS Scales with Symptoms

Over the past 10 years, theorists have suggested that bipolar disorder symptoms result from increases and decreases in the activity of the Behavioral Activation or Facilitation System (BAS or BFS) and the Behavioral Inhibition System (BIS). These neurobehavioral systems are thought to determine the intensity of affective and behavioral responses to incentives and threats. This study examined cross-sectional and prospective associations of self-reported BIS and BAS with mania and depression in a sample of 59 individuals diagnosed with Bipolar I disorder. Depression was tied to BIS, pointing to the importance of sensitivity to threats in depression. However, links between BIS and depression appeared state-dependent. BAS subscales did not correlate with manic symptoms in a state-dependent manner; however, BAS (total scale and reward responsiveness subscale) predicted relative intensification of manic symptoms over time. Thus, evidence suggests that BAS sensitivity may constitute a vulnerability to mania among persons diagnosed with bipolar disorder. Discussion focuses on the integrative potential of the BIS/BAS constructs for linking psychosocial and biological research on bipolar disorder.     

Two subtypes of psychopathic violent offenders that parallel primary and secondary variants

Although psychopathy usually is treated as a unitary construct, a seminal theory posits that there are 2 variants: Primary psychopathy is underpinned by an inherited affective deficit, whereas secondary psychopathy reflects an acquired affective disturbance. The authors investigated whether psychopathy phenotypically may be disaggregated into such types in a sample of 367 prison inmates convicted of violent crimes. Model-based cluster analysis of the Revised Psychopathy Checklist (PCL-R; R. D. Hare, 2003) and trait anxiety scores in the psychopathic subgroup (n = 123; PCL-R > or = 29) revealed 2 clusters. Relative to primary psychopaths, secondary psychopaths had greater trait anxiety, fewer psychopathic traits, and comparable levels of antisocial behavior. Across validation variables, secondary psychopaths manifested more borderline personality features, poorer interpersonal functioning (e.g., irritability, withdrawal, poor assertiveness), and more symptoms of major mental disorder than primary psychopaths. When compared with the nonpsychopathic subgroup (n = 243), the 2 psychopathic variants manifested a theoretically coherent pattern of differences. Implications for etiological research and violence prevention are discussed.     

Validating a distinction between primary and secondary psychopathy with measures of Gray's BIS and BAS constructs

Investigators commonly distinguish between primary and secondary psychopathy (H. Cleckley, 1976; D.T. Lykken, 1995), though there is a lack of consensus regarding the best means to achieve this distinction. To address the validity of using R. D. Hare's (2003) Psychopathy Checklist and the G. Welsh (1956) Anxiety Scale for this purpose, the authors used 2 measures of J. A. Gray's (1987) behavioral inhibition system/behavioral activation system (BIS/BAS). Following D. T. Lykken (1995) and D. C. Fowles (1980), the authors hypothesized that primary psychopathy would be associated with a weak BIS and a normal BAS, whereas secondary psychopathy would be associated with a strong BAS and a normal BIS. Results for primary psychopathy were as predicted. Results for secondary psychopathy clearly supported the strong BAS prediction but provided mixed support for the normal BIS prediction.     

Evaluating the construct validity of psychopathy in black and white male inmates: three preliminary studies

Although Black inmates represent almost half the population of United States prisons and have been included in several studies of psychopathy, there appear to be no published studies to date addressing the validity of the psychopathy construct in Black inmates. Three studies were conducted to assess the validity of the construct in Black male inmates using Hare's Psychopathy Checklist (PCL). In Study 1, we examined the internal structure of the PCL and the relation of checklist scores to several constructs relevant to psychopathy. We observed differences between Blacks and Whites in the distribution of psychopathy scores, in the relation of psychopathy to measures of impulsivity, and in the congruence of the underlying factor structure of the PCL. In Study 2, Black psychopaths were found to manifest a pattern of passive avoidance deficits similar but not identical to that reported for White psychopaths in Newman and Kosson's study. Study 3 demonstrated that psychopaths of both races receive more criminal charges in a wider variety of offense categories than do nonpsychopaths. The psychopathy construct appears tentatively applicable to Blacks, although its components may be somewhat different than for Whites.     

Response perseveration in psychopaths: Interpersonal/affective or social deviance traits?

In order to clarify the role of the two broad components of psychopathy (interpersonal/affective and social deviance; R. D. Hare, 2003) in explaining maladaptive response perseveration in psychopaths, as well as the role of reflection after punished responses in this deficit, the authors administered a card perseveration task to 47 Spanish male inmates assessed using the Hare Psychopathy Checklist-Revised (PCL-R; R. D. Hare, 1991). Hierarchical regressions showed that psychopaths' maladaptive perseveration (more cards played and less money earned) was uniquely predicted by the social deviance features of psychopathy (PCL-R Factor 2)--particularly by its impulsive and irresponsible lifestyle facet (PCL-R Facet 3)--and not by its interpersonal/affective features (PCL-R Factor 1). Moreover, perseveration was related to a lack of reflection both after punishment and after reward feedback. The authors' results, in conjunction with previous evidence indicating perseverative deficits in several impulse control disorders, suggest that response perseveration may not be specific to psychopathy but rather is associated more generally with the externalizing dimension of psychopathology.     

The childhood experiences of psychopaths: a retrospective study of familial and societal factors.

We compared the childhood experiences of criminal psychopaths with those of criminal nonpsychopaths, to examine whether differences in either the type or intensity of adverse experience in childhood could be identified. One hundred and five prisoners, 50 psychopaths, and 55 nonpsychopaths were assessed with the Psychopathy Checklist-Revised (PCL-R) and Childhood Experience of Care and Abuse (CECA) semistructured interviews. Both assessment measures have been demonstrated to be reliable and valid instruments. File information from both adult and child services provided corroborative material. Factor analysis of the childhood experience variables revealed two distinct factors, familial and societal, both of which were highly correlated with adult psychopathy scores. These findings suggest that the experiences psychopaths have in childhood influence adult outcome.     

Psychopathy and malingering of psychiatric disorder in criminal defendants

Because the use of deception is an important clinical characteristic of psychopathy, there is intuitive appeal to the idea that psychopathy and malingering are associated. There is, however, very little research showing that psychopaths are more likely to malinger. We classified a sample of criminal defendants as high, moderate, or low in psychopathy, based on PCL-R scores, and compared their scores on indices typically used to detect malingering on the MMPI-2, the PAI and the SIRS. The high psychopathy group scored significantly higher on the MMPI-2 F and F-K; the PAI NIM, and the SIRS, but not the MMPI-2 Fb, F(p), or the PAI RDF or Mal, lending some support for the DSM-IV recommendation that malingering should be considered whenever there is a diagnosis of antisocial personality disorder. Logistic regression analysis (LGA) revealed that Factor I but not Factor II of the PCL-R significantly discriminated malingerers from nonmalingerers with 75% correct classification. However, receiver operating characteristic (ROC) analysis revealed that psychopathy ratings had poor sensitivity and specificity in the detection of malingering. Calculation of the percentages of those exceeding accepted cut-offs on each of the malingering measures revealed that a high percentage of severe psychopaths did not attempt to feign psychiatric disorder. The results suggest that psychopathy is not a clinically useful indictor of malingering. The results are discussed in terms of confirmatory bias and the impact such a bias could have on the evaluation of criminal defendants.
