Recovery and replication of internalizing and externalizing dimensions within the personality assessment inventory

In this study, we examined the internal structure of 13 Personality Assessment Inventory (PAI; Morey, 1991, 2007) scales in a corrections sample (N = 1,099). Previous findings regarding the PAI internal structure have been somewhat inconsistent. We investigated the utility of a 2-dimensional model comprised of internalization and externalization to organize the 11 PAI clinical scales and 2 additional scales, Suicidal Ideation and Aggression. We randomly divided the sample, and a factor analysis revealed a 2-dimensional model representing internalization and externalization. Confirmatory factor analyses conducted with an independent subsample revealed acceptable fit when the model was revised to include correlated error terms between mood and anxiety disorder scales. The revised model exhibited acceptable fit when cross-validated, had better fit than a 1-dimension model, and demonstrated preliminary construct validity in relation to extratest variables.

Externalizing pathology and the five-factor model: a meta-analysis of personality traits associated with antisocial personality disorder, substance use disorder, and their co-occurrence

In this meta-analysis we examined Five-Factor Model of personality (FFM) characteristics of externalizing disorders. Two pathologies, Antisocial Personality Disorder (APD) and Substance Use Disorder (SUD), have significant levels of co-occurrence that may be due to shared personality traits. Results from 63 samples (N = 15,331) were analyzed in order to summarize and compare five-factor results for APD, SUD, and co-occurring APD/SUD. Shared and unique personality features were identified at both the domain and the facet level of the FFM. Moderation analyses indicated that sample source (clinical versus community) and diagnosis (psychopathy versus DSM-based APD) accounted for some of the variability at the domain level. Results are discussed with respect to personality and externalizing disorders.     

Neuropsychological,Cognitive, and Theoretical Considerations for Evaluation of Bilingual Individuals

As the number of bilinguals in the USA grows rapidly, it is increasingly important for neuropsychologists to be equipped and trained to address the unique challenges inherent in conducting ethical and competent neuropsychological evaluations with this population. Research on bilingualism has focused on two key cognitive mechanisms that introduce differences between bilinguals and monolinguals: (a) reduced frequency of language-specific use (weaker links), and (b) competition for selection within the language system in bilinguals (interference). Both mechanisms are needed to explain how bilingualism affects neuropsychological test performance, including the robust bilingual disadvantages found on verbal tasks, and more subtle bilingual advantages on some measures of cognitive control. These empirical results and theoretical claims can be used to derive a theoretically informed method for assessing cognitive status in bilinguals. We present specific considerations for measuring degree of bilingualism for both clients and examiners to aid in determinations of approaches to testing bilinguals, with practical guidelines for incorporating models of bilingualism and recent experimental data into neuropsychological evaluations. This integrated approach promises to provide improved clinical services for bilingual clients, and will also contribute to a program of research that will ultimately reveal the mechanisms underlying language processing and executive functioning in bilinguals and monolinguals alike.     

Vigilance, active coping, and cardiovascular reactivity during social interaction in young men.

This study of 72 undergraduate men examined the effects of two determinants of cardiovascular response-active coping and vigilance-on blood pressure and heart rate responses to social stressors. Observation of a future debate partner (i.e., vigilance) evoked larger increases in blood pressure than did observation of a less relevant person, apparently through the combination of increases in cardiac output and vascular resistance. Preparation and enactment of efforts to exert social influence (i.e., active coping) evoked heightened blood pressure and heart rate responses through increased cardiac contractility and output. Thus, both vigilance and active coping in social contexts increased cardiovascular reactivity, but apparently through different psychophysiological processes.     

Risk factors associated with eating disorders in Mexican preadolescents with normal weight

This study aimed to identify the differences in body self-esteem, general self-esteem and eating attitudes in a representative sample of children, aged 9-12 years, attending school in México DF. The logistic regression model incorporated the variables of sex, general self-esteem, BMI, age and discrepancy between the perceived image and the ideal image. Participants with an increased risk of eating disorders were girls: a) with less general self-esteem; b) BMI at the upper range of normal weight; c) greater negative discrepancy between perceived and ideal image; d) aged 11-12 years. Higher general self-esteem would act as a protector for eating disorders, while the desire for a thinner ideal body would be a risk factor.     

Spanish drivers' beliefs about speed. Speeding is a major issue of road safety

Extending and updating our knowledge concerning drivers' motivational and cognitive processes is of essential importance if we are to apply policies with long-lasting effects. This study presents data from a representative national survey analyzing the Spanish drivers' beliefs about speed, the risks of speeding, the degree of violation of speed-limits and the reasons for speeding. Results indicate that Spanish drivers rate speeding as a serious offence, yet not among the most dangerous ones. All in all, they claim to comply mostly with the speed limits. However, some interesting violation patterns emerge: observance is lower for generic speed limits according to road type (vs. specific limits shown by certain road signs), and particularly in motorways (vs. single carriageways and urban areas). Risk perception and reasons for speeding emerge as the main factors predicting the levels of speed violations reported. Results suggest that any effective intervention strategy should consider such factors, namely the link between speed, road safety, and drivers' specific reasons for speeding.     

Interpersonal responses among sibling dyads tested for BRCA1/BRCA2 gene mutations.

OBJECTIVE: The familial context plays an important role in psychosocial responses to genetic testing. The purpose of this study was to compare sibling pairs with different combinations of BRCA1/BRCA2 test results on measures of affect, interpersonal responses, and physiological reactions. DESIGN: Forty-nine sibling dyads with different combinations of BRCA1/BRCA2 test results (i.e., mixed, positive, negative) completed a questionnaire, and 35 of the dyads also participated in a laboratory-based discussion of genetic testing. MAIN OUTCOME MEASURES: The primary outcome variables included participant reports of supportive actions toward their sibling, state anger and anxiety, perceptions of sibling behavior, and electrodermal responses. RESULTS: Compared to positive and negative dyads, mixed pairs reported less friendly general support actions, noted more anger, and perceived their sibling to be less friendly and more dominant during the interactions. In comparisons between same-result (i.e., positive, negative) pairs, positive dyads reported more dominant support behaviors and perceived their sibling to be friendlier during the interactions. CONCLUSION: Data suggest that siblings who have different test results may experience more interpersonal strain than siblings who have the same test result. Future research on genetic testing and family relationships can expand upon these findings.
