Take the Money and Run: Psychopathic Behavior in the Trust Game.

We study the association among different sources of individual differences such as personality, cognitive ability and risk attitudes with trust and reciprocate behavior in an incentivized experimental binary trust game in a sample of 220 (138 females) undergraduate students. The game involves two players, player 1 (P1) and player 2 (P2). In the first stage, P1 decides whether to trust and let P2 decide, or to secure an egalitarian payoff for both players. If P1 trusts P2, the latter can choose between a symmetric payoff that is double than the secure alternative discarded by P1, and an asymmetric payoff in which P2 earns more than in any other case but makes P1 worse off. Before the main experiment, we obtained participants' scores for Abstract Reasoning (AR), risk attitudes, basic personality characteristics, and specific traits such as psychopathy and impulsivity. During the main experiment, we measured Heart Rate (HR) and ElectroDermal Activity (EDA) variation to account for emotional arousal caused by the decision and feedback processes. Our main findings indicate that, on one hand, P1 trust behavior associates to positive emotionality and, specifically, to the extraversion's warmth facet. In addition, the impulsivity facet of positive urgency also favors trust behavior. No relation to trusting behavior was found for either other major personality aspects or risk attitudes. The physiological results show that participants scoring high in psychopathy exhibit increased EDA and reduced evoked HR deceleration at the moment in which they are asked to decide whether or not to trust. Regarding P2, we find that AR ability and mainly low disagreeable disinhibition favor reciprocal behavior. Specifically, lack of reciprocity significantly relates with a psychopathic, highly disinhibited and impulsive personality. Thus, the present study suggests that personality characteristics would play a significant role in different behaviors underlying cooperation, with extraversion/positive emotionality being more relevant for initiating cooperation, and low disagreeable disinhibition for maintaining it.

An Investigation of Five Types of Personality Trait Continuity: A Two-Wave Longitudinal Study of Spanish Adolescents from Age 12 to Age 15.

The present study investigated five types of personality trait continuity using two measurement waves of Spanish adolescents (N = 234). Personality traits were measured with the short form of the Junior Spanish NEO-PI-R (JS NEO-S) at ages 12 and 15. The results showed stability in the personality trait structure, as well as decreases in the mean levels of agreeableness and conscientiousness. The results also showed moderate rank-order consistency. Individual-level changes were more pronounced for neuroticism and conscientiousness. Approximately 90% of the participants showed ipsative consistency. The findings showed some personality trait changes occurred from age 12 to 15, but the changes were less marked than expected during this period of biological and social development. Our results also support the disruption hypothesis, as we found dips in conscientiousness and, to a lesser degree, agreeableness.

Alcohol Expectancies Mediate and Moderate the Associations between Big Five Personality Traits and Adolescent Alcohol Consumption and Alcohol-Related Problems.

Personality and expectancies are relevant psychological factors for the development of adolescent alcohol use and misuse. The present study examined their direct, mediated and moderated effects on different drinking behaviors in adolescence. Personality domains of the five-factor model, positive and negative alcohol expectancies (AEs), alcohol use during the week and the weekend, and alcohol-related problems were assessed in a sample of 361 adolescents. Different personality dimensions were directly associated with specific alcohol outcomes: Extraversion, low Conscientiousness and low Openness were associated with weekend alcohol use; low Agreeableness was related to weekday use; whereas low Agreeableness, low Conscientiousness and Extraversion were associated with alcohol-related problems. In addition, positive AEs mediated the relationship between Extraversion and alcohol use, whereas both positive and negative expectancies mediated the association between Neuroticism and alcohol consumption and alcohol-related problems. Finally, both types of expectancies interacted with Extraversion to predict alcohol problems. Our results highlight the importance of examining the complex interplay of comprehensive personality models and AEs to gain a better understanding of the development of different alcohol use and misuse patterns in adolescence.

A longitudinal examination of different etiological pathways to alcohol use and misuse.

BACKGROUND: Sher, Grekin, and Williams (2005) pointed out the existence of 4 main etiological, but not mutually exclusive, models that might explain the development of alcohol use and misuse. The aim of the present study was to explore 3 of these 4 pathways in which psychological (personality and drinking motives) and environmental (child maltreatment) variables may play a relevant role: positive affect regulation, negative affect regulation, and deviance proneness. METHODS: Three hundred and fourteen young adults in the 18 to 29 year age range completed different personality, alcohol use, and child maltreatment questionnaires at Time 1. Five years later, they responded to drinking motives, antisocial behavior, alcohol use, and alcohol-related problems questionnaires. RESULTS: The path analyses showed that emotional abuse predicted negative emotionality, which, in turn, prospectively predicted alcohol-related problems through coping-with-depression drinking motives (negative affect regulation). Emotional neglect predicted lesser positive emotionality, and physical abuse predicted unconscientious disinhibition personality characteristics. In turn, these 2 broad personality domains predicted drinking at weekends at Time 2 through enhancement drinking motives (positive affect regulation). Finally, physical neglect predicted disagreeable disinhibition, and both disinhibition domains directly predicted antisocial behavior 5 years later which, in turn, predicted drinking at weekends, drinking on weekdays, and alcohol-related problems (deviance proneness). CONCLUSIONS: The findings describe the specific role of distal (maltreatment and personality) and more proximal (antisocial behavior and drinking motives) variables in the different pathways involved in the development of alcohol use and misuse.

Spanish adaptation of the expectancy questionnaire (EQ) about alcohol effects in adolescents / Adaptación española del Cuestionario de Expectativas (EQ) sobre los efectos del alcohol en adolescentes

Background: Alcohol-related expectancies are especially relevant in relation to alcohol consumption during adolescence. The main aim of this study was to adapt and translate into Spanish (Castilian) the Expectancy Questionnaire (EQ), and to study its psychometric properties in adolescents. Method: The sample was composed of 514 adolescents (57.20% female, mean age = 15.21; SD = .63) who completed the EQ and the alcohol consumption questionnaire AIS-UJI. Results: Confirmatory factor analysis indicated that an eight-factor model, grouped into two general factors of positive and negative expectancies, had acceptable fit indices. Cronbach’s alphas ranged from .75 to .96. Finally, the structural equation model showed that positive expectancies were positively related to alcohol use, whereas negative expectancies were negatively related to drinking. Conclusions: Results showed that the Spanish version of the EQ for adolescents is a valid and reliable questionnaire to measure expectancies about alcohol effects (AU)

Antecedentes: las expectativas sobre los efectos del alcohol es un factor especialmente relevante en el consumo de alcohol en la adolescencia. El objetivo del presente trabajo fue adaptar y traducir al castellano el Cuestionario de Expectativas (EQ), y estudiar sus propiedades psicométricas en adolescentes. Método: la muestra estuvo compuesta por 514 adolescentes (57,20% chicas, edad media 15,21; DT = ,63) que cumplimentaron la versión española del EQ y el cuestionario de consumo de alcohol AIS-UJI. Resultados: el análisis factorial confirmatorio mostró que un modelo jerárquico de ocho factores agrupados en dos factores generales de expectativas positivas y negativas presentaba índices de ajuste aceptables. Los alfas de Cronbach de las escalas fueron de ,75 a ,96. Finalmente, el modelo de ecuaciones estructurales mostró que las expectativas positivas se relacionaron positivamente con el consumo de alcohol y las expectativas negativas lo hicieron en sentido opuesto. Conclusiones: los resultados del presente trabajo indican que la versión española del EQ es un cuestionario fiable y válido para la evaluación de las expectativas sobre los efectos del alcohol en adolescentes (AU)

Assessing the five factors of personality in adolescents: the junior version of the Spanish NEO-PI-R.

This article presents the development of a junior version of the Spanish (Castilian) NEO Personality Inventory-Revised (JS NEO) suitable for adolescents aged 12 to 18 years. The psychometric properties of the new JS NEO were investigated using two samples of 2,733 and 983 adolescents in Spain. The results showed that the adult NEO-PI-R factor structure was replicated with the junior version of the inventory and that the reliabilities of the scales were adequate. The cross-form correlations between the junior and the adult versions of the questionnaires indicated good equivalence indices. Furthermore, a joint factor analysis of the JS NEO and the Big Five Questionnaire-Children (BFQ-C) provided additional evidence for the construct validity of the JS NEO.

Childhood abuse, the BDNF-Val66Met polymorphism and adult psychotic-like experiences.

BACKGROUND: The well-established relationship between childhood adversity and psychosis is likely to involve other factors such as genetic variants that can help us to understand why not everyone exposed to adverse events develops psychotic symptoms later in life. AIMS: We investigated the influence of childhood abuse and neglect on positive and negative psychotic-like experiences in adulthood and the potential moderating effect of the BDNF-Val66Met polymorphism. METHOD: Psychotic-like experiences and childhood adversity were assessed in 533 individuals from the general population. RESULTS: Childhood abuse showed a strong independent effect on the positive dimension of psychotic-like experiences (ß = 0.16, s.e. = 0.05, P = 0.002). Furthermore, this association was moderated by the BDNF-Val66Met polymorphism (ß = 0.27, s.e. = 0.10, P = 0.004). CONCLUSIONS: Individuals exposed to childhood abuse are more likely to report positive psychotic-like experiences. Met carriers reported more positive psychotic-like experiences when exposed to childhood abuse than did individuals carrying the Val/Val genotype. Therefore, the observed gene-environment interaction effect may be partially responsible for individual variation in response to childhood abuse.

Drinking motives in clinical and general populations.

AIMS: This paper had three aims: (1) to validate a Spanish adaptation of the Modified Drinking Motives Questionnaire-Revised (M DMQ-R), (2) to explore the relationship of each drinking motive with different patterns of alcohol use, and (3) to compare the drinking motives of moderate drinkers, heavy drinkers, and alcohol abusing/dependent individuals. METHODS: Two studies were carried out. In Study 1, a sample of 488 participants completed the M DMQ-R and a self-report scale of alcohol consumption in order to study the factor structure and different indices of reliability and validity of the Spanish M DMQ-R. In Study 2, we compared the drinking motives of moderate and heavy drinkers from Study 1 and an additional sample of 59 clinical drinkers. RESULTS: The M DMQ-R demonstrated sound reliability and validity indices. Coping-with-anxiety, social, and enhancement motives predicted higher alcohol use on weekends, but only coping-with-anxiety and social motives were related to consumption on weekdays. Furthermore, moderate drinkers had the lowest scores for all motives, whereas alcohol-dependent participants obtained the highest scores for negative reinforcement drinking motives. CONCLUSION: The Spanish M DMQ-R is a reliable and valid measure of drinking motives and has potential for assisting with treatment planning for problem drinkers.

Adaptación para adolescentes de la versión española del NEO PI-R(JS NEO) / Junior version of the Spanish NEO PI-R (JS NEO)

Este artículo presenta los primeros datos del desarrollo de la versión española para adolescentes, entre 12 y 17 años, del NEO PI-R (JS NEO). Noventa y dos de los 240 ítems fueron modificados con el fin de adaptar el vocabulario de los mismos a este grupo de edad. Las propiedades psicométricas del JS NEO han sido investigadas en una muestra de 2.505 adolescentes. Los resultados muestran cómo la estructura factorial encontrada con el NEO PI-R para adultos se replica en la versión junior. Las fiabilidades de consistencia interna y estabilidad temporal de las escalas fueron adecuadas en la mayor parte de los casos. Además, la correlación entre las escalas de las versiones para adultos (NEO PI-R) y adolescentes (JS NEO) muestran que la versión para adolescentes presenta una validez de constructo adecuada

The use of VR in the treatment of panic disorders and agoraphobia.

Panic disorder with agoraphobia (PDA) is considered an important public health problem. The efficacy of cognitive-behavioral therapy (CBT) for PDA has been widely demonstrated. The American National Institute of Health recommended Cognitive-Behavioral programs as the treatment of choice for this disorder. This institution also recommended that researchers develop treatments whose mode of delivery increases the availability of these programs. Virtual Reality based treatments can help to achieve this goal. VR has several advantages compared with conventional techniques. One of the essential components to treat these disorders is exposure. In VR the therapist can control the feared situations at will and with a high degree of safety for the patient, as it is easier to grade the feared situations. Another advantage is that VR is more confidential because treatment takes place in the therapist's office. It is also less time consuming as it takes place in the therapist's office. Considering the wide number of situations and activities that agoraphobic patients use to avoid, VR can save time and money significantly. Another advantage in treating PDA using VR is the possibility of doing VR interoceptive. VR could be a more natural setting for interoceptive exposure than the consultation room because we can elicit bodily sensations while the patient is immerse in VR agoraphobic situations. Finally, we think that VR exposure can be a useful intermediate step for those patients who refuse in vivo exposure because the idea of facing the real agoraphobic situations is too aversive for them. In this chapter we offer the work done by our research team at the VEPSY-UPDATED project. We describe the VR program we have developed for the treatment of PDA and we summarize the efficacy and effectiveness data of a study where we compare a cognitive-behavioral program including VR for the exposure component with a standard cognitive-behavioral program including in vivo exposure and with a waiting list control condition. Our findings support the efficacy and effectiveness of VR for the treatment of PDA.

Clinically significant virtual environments for the treatment of panic disorder and agoraphobia.

The aim of this work is the description of virtual environments designed to apply exposure therapy in the treatment of panic disorder and agoraphobia. The program allows the simultaneous exposure to two different kinds of stimuli usually avoided by panic disorder and agoraphobia sufferers (external and interoceptive). The characteristics of the virtual environments are described, as well as the target behaviors that can be simulated with these virtual environments.
