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. C...

This article presents the preliminary data of the development of a Junior version of the Spanish NEO PI-R (JS NEO), suitable for teenagers from 12 to 17 years of age. From the 240 original English items, 92 were modified or reworded to some degree to make the vocabulary adequate for this age group. The psychometric properties of the JS NEO were investigated in a sample of 2,505 adolescents. Results showed that the adult NEO PI-R factor structure was replicated in the junior version of the inventory. Internal consistency and temporal stability reliabilities of the scales were adequate for most scales. Furthermore, the cross-form correlations between the junior (JS NEO) and the adult (NEO PI-R) scales indicated satisfactory construct validity of the junior version of the inventory.

Este cuestionario de 150 items evalua las cinco dimensiones y las treinta facetas del Modelo de los Cinco Factores. Las propiedades psicometricas del JS NEO-S fueron investigadas en una muestra de 2.546 adolescentes. Los resultados replicaron la estructura factorial de la version extensa (JS NEO). Las fiabilidades de consistencia interna y estabilidad temporal de las escalas, en intervalos de un mes y un ano, fueron adecuadas. Ademas, la correlacion entre las escalas de la version corta para adolescentes y la version para adultos, NEO-PI-R, indicaban un alto grado de equivalencia entre las dos formas. Asimismo, se estudio la asociacion del JS NEO con el BFQ-NA que evalua los cinco factores a nivel de las dimensiones, ya que no tiene subescalas para las facetas. Las correlaciones entre estos cuestionar...

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 ...

In consequence, how sociocultural processes are involved in explaining and understanding psychopathological manifestations is not very clearly defined (Agbayani-Siewert, Takeuchi & Pangan, 1999; Fabrega, 1995). Nevertheless, parallel to this, there has also been a growing and renewed interest in understanding the role played by culture in mental disorders in order to allow cultural aspects to be included in the conceptualization of psychopathologies, in the light of the results obtained by a large number of research studies (for a review, see Lopez & Guarnaccia, 2005). This interest in seeking to achieve the integration and interaction of biopsychosocial variables within the explanation of psychopathological behavior represented the beginning of a change of paradigm as regards the explanation of both normal and psychopathological human behavior (Mezzich, Lewis-Fernandez & Ruiperez, 2003). This change in paradigm involves accepting the fact that psychic phenomena can be explained on a molecular and cellular level, involving tissues, organs, systems, the organism, the way information is processed, the physical surroundings or the sociocultural context (Cacioppo & Berntson, 1992, 2006; Mezzich et al. , 2003; Westen, 2004).

Similarly, the deleterious impact of early traumatic experiences on depression seems to be moderated by individual genetic variability. Serotonin transporter (5-HTT) and brain-derived neurotrophic factor (BDNF) modulate the effect of childhood adversity on adult depression, although inconsistencies across studies have been found. Moreover, the gene×environment (G×E) interaction concerning the different types of childhood adversity remains poorly understood. The aim of this study was to analyse the putative interaction between the 5-HTT gene (5-HTTLPR polymorphism), the BDNF gene (Val66Met polymorphism) and childhood adversity in accounting for adult depressive symptoms.MethodA sample of 534 healthy individuals filled in self-report questionnaires of depressive symptomatology [the Symptom Check List 90 Revised (SCL-90-R)] and different types of childhood...
