Are all psychopathic individuals low-anxious?

Theorists commonly assume that true or primary psychopathic individuals experience little anxiety or neurotic conflict. This study examined the relationship between psychopathy and anxiety in 104 Caucasian and 113 African American incarcerated men using the Psychopathy Checklist—Revised (PCL—R; R. D. Hare, 1991) and multiple self-report measures to tap diverse interpretations of the anxiety construct (i.e., neuroticism, traditional definitions of anxiety, and fear). Analyses involving zero-order, semipartial, and point-biserial correlations indicate that PCL—R psychopathy and the anxiety construct are essentially independent. These findings suggest that either (a) the traditional belief that all psychopathic individuals are low-anxious is incorrect or (b) the PCL—R is not an adequate measure of primary psychopathy.

Delay of gratification in psychopathic and nonpsychopathic offenders.

Delay of gratification is a prototypical measure of self-control that merits systematic investigation in psychopaths. White male prisoners were provided with repeated opportunities to select an immediate response with uncertain reward or a delayed response with a higher rate of reward under 1 of 3 incentive conditions. Psychopaths' performance depended on their level of trait anxiety and incentive condition: Whereas low-anxious psychopaths were relatively unwilling to delay when omission of expected rewards also incurred monetary punishments, they displayed relative superior performance when the task involved rewards only. Findings complement those for passive avoidance learning in psychopaths and suggest that inhibitory self-control in low-anxious psychopaths is somewhat impaired under conditions involving a combination of monetary rewards and punishments.

Testing Damasio's somatic marker hypothesis with psychopathic individuals: Risk takers or risk averse?

Damasio and colleagues (A. R. Damasio, 1994; A. R. Damasio, D. Tranel, & H. Damasio, 1990) have theorized about a possible relationship between somatic markers and the behavior of psychopathic individuals (Ps), but, to date, there are no published data regarding the proposed relationship. The authors assessed 96 Caucasian and 71 African American male offenders using R. D. Hare's (1991) Psychopathy Checklist—Revised and used a modified version of Bechara and colleagues' (A. Bechara, A. R. Damasio, H. Damasio, & S. W. Anderson, 1994; A. Bechara, H. Damasio, D. Tranel, & A. R. Damasio, 1997) gambling task to test the hypothesis that Ps would, consistent with the somatic marker hypothesis, fail to become risk averse. Results indicated that level of anxiety, but not psychopathy, was predictive of response choices. Several limitations and implications of the study are noted.

Low-anxious, high-anxious, and repressive coping styles: Psychometric patterns and behavioral and physiological responses to stress.

A long-standing problem in stress research has been that individuals' reports of their tendencies to become anxious are often inconsistent with relevant behavioral and physiological indices. This study investigated the distinction between (a) truly low-anxious Ss, who report low trait anxiety on the Taylor Manifest Anxiety Scale and low defensiveness on the Marlowe-Crowne Social Desirability Scale, and (b) repressors, who report low anxiety but high defensiveness. These groups were compared with a moderately high-anxious one. Heart rate, spontaneous skin resistance responses, and forehead muscle tension were recorded from 40 male college students during a phrase association task. Significant differences in the 3 physiological measures as well as in 3 behavioral ones (reaction time, content avoidance, and verbal interference) all indicated that the repressors were more stressed than the low-anxious Ss despite their claims of lower trait anxiety. The high-anxious group exhibited a 3rd pattern suggesting an intermediate level of anxious responding. These data document the need to distinguish between repressors and truly low-anxious persons in research concerned with relations between self-reported anxiety and behavioral and physiological responses to stress.

Evaluating the generalizability of a fear deficit in psychopathic African American offenders.

Laboratory studies of psychopathy have yielded an impressive array of etiologically relevant findings. To date, however, attempts to demonstrate the generalizability of these findings to African American psychopathic offenders have been largely unsuccessful. The fear deficit has long been regarded as the hallmark of psychopathy, yet the generalizability of this association to African American offenders has not been systematically evaluated. In this study, we used an instructed fear paradigm and fear-potentiated startle to assess this deficit and the factors that moderate its expression in African American offenders. Furthermore, we conceptualized psychopathy using both a unitary and a two-factor model, and we assessed the constructs with both interview-based and self-report measures. Regardless of assessment strategy, results provided no evidence that psychopathy relates to fear deficits in African American offenders. Further research is needed to clarify whether the emotion deficits associated with psychopathy in European American offenders are applicable to African American offenders.

Effects of stimulation intensity on sociopathic avoidance learning.

On the basis of scores on standardized tests (e.g., the Taylor Manifest Anxiety Scale), 90 public offenders were selected to represent low, medium, and high levels of anxiety and low and high levels of sociopathy. Ss were exposed to an avoidance situation under either low, medium, or high levels of background auditory stimulation. The avoidance task allowed shock to be averted through appropriate active and passive avoidance responses in the presence of visually presented cues. Anxiety, sociopathy, and auditory stimulus intensity interacted in their effects on avoidance behavior. Primary sociopaths learned to avoid shock more effectively under conditions of higher auditory stimulus intensity, while avoidance behavior of control Ss was not affected by changes in the level of auditory stimulation.

Emotion processing in the criminal psychopath: The role of attention in emotion-facilitated memory.

The response modulation hypothesis specifies that low-anxious psychopathic individuals have difficulty processing information outside their primary attentional focus. To evaluate the applicability of this model to affective processing, the authors had 239 offenders, classified with the Psychopathy Checklist--Revised (R. D. Hare, 2003) and the Welsh Anxiety Scale (G. Welsh, 1956), perform 1 of 3 emotion memory tasks that examined the effects of emotion on memory for primary and contextual information. Regardless of anxiety level, psychopathic and control offenders demonstrated a significant and comparable memory bias for emotional over neutral words in the primary conditions. However, psychopathic individuals showed significantly less memory bias than did controls in the contextual conditions. Results indicate that the impact of emotion on memory is moderated by attentional factors. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Comparing the Developmental Trajectories of Marijuana Use of African American and Caucasian Adolescents: Patterns, Antecedents, and Consequences.

Adolescent marijuana use has tripled recently, and the once-noted race gap between African American and Caucasian adolescents in marijuana use appears to have disappeared. Yet, relatively little research has examined marijuana use among African American adolescents. In this study, we examined developmental trajectories of marijuana use among Caucasian and African American adolescents to identify whether and when differences in marijuana use appear and whether the precursors and outcomes associated with these developmental trajectories differ by race. Findings indicate that both the developmental patterns and outcomes associated with marijuana use are different for African American and Caucasian adolescents. Early-onset Caucasian and mid-onset African American adolescents experienced the greatest number of negative outcomes later in life associated with their marijuana use, suggesting that groups to target for intervention may vary by race.

Validation of depression and anxiety measures in White and Black youths: Multitrait–multimethod analyses.

The authors obtained yearly self-report, peer nomination, and teacher rating assessments of depression symptoms, anxiety symptoms, and social acceptance on 2 cohorts of African American (ns?=?139 and 184) and Caucasian school children (ns?=?328 and 339), yielding a total of 6 waves of data between 3rd and 8th grade. Confirmatory factor analyses revealed that the measures manifested significant convergent and discriminant validity in both groups. Multigroup analyses further demonstrated that the measures were equally valid across ethnic groups. Peer nomination measures of depression and anxiety symptoms were biased, however, leading to the underestimation of psychopathology in African American children and adolescents. Allowing for this bias, the authors discovered that African American children evinced more signs of depression and anxiety in Grades 3, 4, and 5 than did Caucasian children. Such differences were not significant in Grades 6, 7, and 8. No ethnic group differences emerged on the social acceptance dimension. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effect on intimal hyperplasia of dexamethasone released from coated metal stents compared with non-coated stents in canine femoral arteries

Previous studies suggest that esthetic Caucasian profiles exhibit fuller lips than the norm for their race, while esthetic African American profiles are similar to those of esthetic Caucasians. The present study was undertaken to compare the profiles of female Caucasian and African American models and their nonmodel counterparts. Four groups of 30 subjects were evaluated: Caucasian models [CM], Caucasian controls [CC], African American models [AM], and African American controls [AC]. The models' profiles were photographed from current fashion magazines, the photos were scanned, and 17 landmarks were digitized. Each profile was standardized for size and oriented along the N'-Sn' line on a Macintosh 6115CD computer. Control photographs were processed in a similar manner. Twenty-six variables were measured for each profile. Means, ranges, and standard deviations were computed along with unpaired, two-tailed Student's t-tests (p<0.05) to evaluate group differences. The results showed that for the AM and AC profiles, all but two of the 26 variable were similar. For the CM and CC profiles, eight variables demonstrated significant differences. Between-race comparisons demonstrated greater numbers of parameters that were significantly different: CM/AM with 18 and CM/AC, CC/AC, and CC/AM with 22 each. Most of the differences involved the lips. Vertical soft tissue proportions for the four groups did not follow a 40/20/40 ratio. Caucasian and African American models displayed significantly different profile characteristics. The African American models and controls showed similar profile features, whereas greater differences were observed between Caucasian models and controls. Based on our study, the African American profile currently presented in the mass media is not "Caucasian-like." In fact, it appears that Caucasian models display more ethnic features than African American models do Caucasian features, suggesting that previously held concepts of facial beauty may no longer apply.     

Approach and avoidance motivation in psychopathic criminal offenders during passive avoidance.

The authors evaluated competing theories that attribute psychopathic individuals' poor passive avoidance to a strong activating system, a weak inhibitory system, or poor modulation of behavioral activation when inhibitory cues appear. In Study 1, the continuous motor task involved a reward phase to elicit the activating system followed by a passive avoidance phase. Study 2 tested the generality of the theories by using an active avoidance phase to elicit the activating system. Heart rate and response speed results from Study 1 best supported the strong activating system and poor response modulation models in low-anxiety psychopathic offenders. Study 2 results did not clearly support any of the models. Further research is needed to determine if excessive activation by reward and poor response modulation are associated with passive avoidance deficits and other characteristics of low-anxiety psychopathic offenders.

Deficient response modulation and emotion processing in low-anxious Caucasian psychopathic offenders: Results from a lexical decision task.

The clinical and research literatures on psychopathy have identified an emotion paradox: Psychopaths display normal appraisal but impaired use of emotion cues. Using R. D. Hare's (1991) Psychopathy Checklist--Revised and the G. S. Welsh Anxiety Scale (1956), the authors identified low-anxious psychopaths and controls and examined predictions concerning their performance on a lexical-decision task. Results supported all the predictions: (a) low-anxious psychopaths appraised emotion cues as well as controls; (b) their lexical decisions were relatively unaffected by emotion cues; (c) their lexical decisions were relatively unaffected by affectively neutral word-frequency cues; and (d) their performance deficits were specific to conditions involving right-handed responses. The authors propose that deficient response modulation may underlie both the emotional and cognitive deficits associated with low-anxious psychopaths.

Unfair treatment is associated with poor sleep in African American and Caucasian adults: Pittsburgh SleepSCORE project.

Objective: To test the association between self-reported unfair treatment and objective and self-reported sleep characteristics in African American and Caucasian adults. Design: Cross-sectional study of 97 African American and 113 Caucasian middle-aged adults. Main Outcome Measures: Participants completed: (a) two-night in-home, polysomnography (PSG) sleep study, (b) sleep diaries and actigraph assessments across 9 days and nights, and (c) self-report measures of sleep quality in the past month, and daytime sleepiness in the past 2 weeks. Results: Greater unfair treatment was associated with reports of poorer self-reported sleep quality and greater daytime sleepiness, shorter sleep duration, and lower sleep efficiency as measured by actigraphy and PSG, and a smaller proportion of rapid eye movement (REM) sleep. Racial/ethnic differences were few. Exploratory analyses showed that nightly worry partially mediated the associations of unfair treatment with sleep quality, daytime sleepiness, sleep efficiency (actigraphy), and proportion of REM sleep. Conclusion: Perceptions of unfair treatment are associated with sleep disturbances in both African American and Caucasian adults. Future studies are needed to identify the pathways that account for the association between unfair treatment and sleep. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Mechanisms of change in multisystemic therapy: Reducing delinquent behavior through therapist adherence and improved family and peer functioning.

The mechanisms through which multisystemic therapy (MST) decreased delinquent behavior were assessed in 2 samples of juvenile offenders. Sample 1 included serious offenders who were predominantly rural, male, and African American. Sample 2 included substance-abusing offenders who were predominantly urban, male, and Caucasian. Therapist adherence to the MST protocol (based on multiple respondents) was associated with improved family relations (family cohesion, family functioning, and parent monitoring) and decreased delinquent peer affiliation, which, in turn, were associated with decreased delinquent behavior. Furthermore, changes in family relations and delinquent peer affiliation mediated the relationship between caregiver-rated adherence and reductions in delinquent behavior. The findings highlight the importance of identifying central change mechanisms in determining how complex treatments such as MST contribute to ultimate outcomes.

Juvenile rheumatoid arthritis in African Americans

OBJECTIVE: To examine racial differences in disease expression in African American and Caucasian children with pauciarticular and polyarticular juvenile rheumatoid arthritis (JRA). METHODS: A retrospective chart review was conducted of 35 African American and 137 Caucasian children with pauciarticular and polyarticular JRA. RESULTS: African American children were significantly older than Caucasian children at the time of presentation. This was true both for the group as a whole and for each of the disease onset subtypes. African American children were less likely to have positive antinuclear antibody tests than Caucasian children. This finding paralleled a low incidence of uveitis in African American children. African American children were also more likely to have IgM rheumatoid factors (detected by latex agglutination) than Caucasian children. This was true even for African American children with pauciarticular JRA. CONCLUSION: There are significant phenotypic differences between African American and Caucasian children with JRA.     

Predictive validity of automatic self-associations for the onset of anxiety disorders.

Negative self-cognitions are assumed to play an important role in the onset of anxiety disorders. Current dual-process models emphasize the relevance of differentiating between more automatic and more deliberate self-cognitions in this respect. Therefore, this study was designed to test the prognostic value of both deliberate and automatic self-anxious associations as a generic vulnerability factor for the onset of anxiety disorders between baseline and 2-year follow-up. To test the disorder specificity of negative self-associations, we also measured self-depressed associations. Self-report measures of depressive symptoms, anxiety symptoms, neuroticism, and fearful avoidance were included as covariates. Healthy controls (n = 593), individuals who had depression (n = 238), and individuals remitted from an anxiety disorder (n = 448) were tested as part of the Netherlands Study of Depression and Anxiety. Deliberate self-anxious associations predicted the onset of anxiety disorders in all groups. Automatic self-anxious associations showed predictive validity only in individuals remitted from an anxiety disorder or in currently depressed individuals. Although deliberate self-depressed associations were related to the onset of anxiety disorders as well, automatic self-depressed associations were not. In the (remitted) patient groups, only deliberate self-anxious associations showed independent predictive value for the onset of anxiety disorders together with self-reported fearful avoidance behavior. In the healthy controls, only a composite index of negative emotionality (depressive or anxiety symptoms and neuroticism) showed independent predictive validity. This study provides the first evidence that automatic and deliberate self-anxious associations have predictive value for the future onset of anxiety disorders.

Using the SWAP-200 with novice psychodynamic clinicians: Is it reliable, useful, and non-biased?

Eight-one first-year doctoral students in a psychodynamic program completed the SWAP-200 on a standardized case to determine the usefulness of the instrument with novice clinicians and to assess race-based differences in diagnostic outcome. The test case represented either a Caucasian or an African American woman who had either a masochistic or an obsessive–compulsive character style. Results revealed that the SWAP-200 was able to detect differences between the obsessive and masochistic cases in theoretically consistent ways. Although the SWAP-200 was useful with novice clinicians, the results revealed that the African American patient was rated as having greater narcissistic and antisocial features than the Caucasian patient. The Caucasian patient was rated as having greater avoidant, dependent, and depressive features compared to the African American patient. Implications of the findings and recommendations for training and future research are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Examining the relationship between current attachment status and freely recalled autobiographical memories of childhood.

This study investigated the relationship between individual differences in attachment and the free recall of childhood memories. Specifically, it focuses on how attachment anxiety and attachment avoidance, using the Experiences in Close Relationship Scale self-report, relate to the affective quality and the presence of caregivers in memories from childhood. Participants were 79 undergraduate and masters students attending a northeast university. Participants completed a memory task designed to elicit freely recalled memories from childhood. They then rated the affective valence (positive/negative) and intensity of each memory, and identified memories in which caretakers were present. Attachment avoidance was related to recalling more negative memories involving caretakers and was negatively related to the average intensity of memories involving caretakers. The results support and extend previous research suggesting that affect regulation strategies employed by individuals high in attachment anxiety and high in attachment avoidance are linked to differences in how information about the past is recalled.

Do gender differences in help avoidance vary by ethnicity? An examination of African American and European American students during early adolescence.

The present research examined whether the nature of gender differences varies by race for two types of academic engagement in the classroom (help avoidance and voice with the teacher) in a sample of early adolescents (N = 456; 55% female, 60% African American and 40% European American) making the transition to middle school. Growth curve analyses indicated that help avoidance increased over time, voice remained stable, and achievement declined. In line with hypotheses based on cultural variations in the female role, there were no gender differences in help avoidance for African American students, whereas for European American students, girls were lower in help avoidance than were boys. For African American students, there were no gender differences in voice with the teacher, whereas for European American students, girls were higher than were boys. These group differences were present at all 3 waves. For all students, increases in help avoidance negatively predicted changes in achievement, whereas increases in voice positively predicted achievement. Results underscore the importance of examining gender and ethnicity together to understand academic adjustment during early adolescence. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
