Virtual reality versus computer-aided exposure treatments for fear of flying

Evidence is growing that two modalities of computer-based exposure therapies—virtual reality and computer-aided psychotherapy—are effective in treating anxiety disorders, including fear of flying. However, they have not yet been directly compared. The aim of this study was to analyze the efficacy of three computer-based exposure treatments for fear of flying: virtual reality exposure therapy (VRET), computer-aided exposure with a therapist’s (CAE-T) assistance throughout exposure sessions, and self-administered computer-aided exposure (CAE-SA). A total of 60 participants with flying phobia were randomly assigned to VRET, CAE-T, or CAE-SA. Results indicate that the three interventions were effective in reducing fear of flying at posttreatment and at 1-year follow-up; furthermore, there were no significant differences between them in any of the outcome measure. Large within-group effect sizes were found for all three treatment conditions at both posttreatment and at follow-up. The results suggest that therapist involvement might be minimized during computer-based treatments and that CAE can be as effective as VRET in reducing fear of flyin

Retos de la investigación psicológica en salud mental

The magnitude and impact of mental disorders does not correspond to the resources devoted to research and attention. Although we have made significant progress in their understanding and the efficacy of the psychological treatments, we are still far from an optimal situation. This paper focuses on one of the major issues which we consider fundamental challenges and needs in this area, the increase in research focusing on psychopathology, especially on the mechanisms and processes that explain and maintain mental disorders, as a key point for the design and development of new psychological interventions for the prevention, treatment, and promotion of mental health. The aim is to promote discussion among all stakeholders and debate on those lines we think as a priority.La magnitud y el impacto que suponen los trastornos mentales no se corresponden con los recursos que se dedican a su investigación y atención. Aunque hemos avanzado notablemente en su comprensión y en la eficacia de los tratamientos psicológicos que intentan paliarlos, estamos aún lejos de la situación óptima. Este trabajo se centra en uno de los retos y una de las necesidades que consideramos fundamentales, el incremento de la investigación focalizada en psicopatología, especialmente sobre los mecanismos y procesos que explican y mantienen estos problemas, como eje básico para el desarrollo de nuevas intervenciones psicológicas, tanto para la prevención como para el tratamiento y promoción de la salud mental. El objetivo es promover la discusión entre los agentes implicados y reflexionar sobre las líneas de trabajo que creemos prioritarias.Este trabajo ha sido financiado por el Ministerio Español de Economía y Competitividad (MINECO), a través de la Red de Excelencia PROMOSAM financiada por el MINECO (PSI2014-56303-REDT)

Spanish version of the savings inventory - Revised - Adaptation, psychometric properties, and relationship to personality variables

The factor structure, psychometric properties, and relationship with personality variables of a Spanish version of the Savings Inventory-Revised (SI-R) are investigated in a sample of 381 undergraduate students. A maximum likelihood factor analysis suggests a three-factor structure, which is similar but not identical to that of the original English version. The three factors mirror the three hypothesized domains of compulsive hoarding: acquisition, difficulty discarding, and clutter. The Spanish SI-R demonstrates acceptable high internal consistency and test-retest reliability, but its divergent validity is weaker than expected because of a significant overlap with depressive symptoms. Different SI-R factors are associated with different personality traits: Whereas the difficulty discarding dimension is predominantly associated with susceptibility to punishment, the acquisition dimension is predominantly associated with susceptibility to reward. The authors conclude that the Spanish SI-R is a promising instrument to measure hoarding symptoms

Temporal stability of obsessive-compulsive symptom dimensions in an undergraduate sample: a prospective 2-year follow-up study

The temporal stability of obsessive-compulsive symptom dimensions was studied in a nonclinical student sample. The Obsessive-Compulsive Inventory— Revised was administered twice to 132 undergraduate students during a 2-year period. There were no significant changes in symptom dimension scores between the baseline and follow-up, except for the Obsessing scale. The score of each dimension at follow-up was strongly and uniquely predicted from the score on the same dimension at baseline. The results indicate that obsessive-compulsive symptom dimensions tend to be temporally stable in nonclinical participants, replicating similar studies in clinical populations

Psychometric properties of the Spanish version of the Obsessive-Compulsive Inventory-Revised in a non-clinical sample

The psychometric properties of a Spanish version of the Obsessive–Compulsive Inventory—Revised (OCI-R) were examined in a non-clinical student sample (n = 381). A confirmatory factor analysis replicated the original six-factor structure. The total and each of the subscales of the Spanish OCI-R demonstrated moderate to good internal consistency and test-retest reliability, moderate convergent validity and good divergent validity. The Spanish version of the OCI-R retains the sound psychometric properties of the original version

Preferencias de pacientes con miedo a volar sobre tres tratamientos de exposición con ordenador

This study analyses participants' preferences regarding three computer-aided exposure treatments for fear of flying (FF): virtual reality exposure treatment assisted by a therapist (VRET), computer-aided exposure with a therapist present throughout exposure sessions (CAE-T), and self-administered computer-aided exposure (CAE-SA). Sixty participants with FF were randomly assigned to one of these treatments. At the end of a treatment, a demonstration of the other two treatment options was given and patients were asked to rate their preferences. At post-treatment, assessment data on treatment preferences were obtained from 48 participants (CAE-T n= 14; CAE-SA n= 16, and VRET n= 18). Participants favoured VRET as the most effective, the most recommended, but also they valued it as the most aversive. Attending to the specific treatment condition received by the participants, results showed that in VRET and CAE-T, participants assessed their own treatment as more preferred, more efficacious and more recommendable. Results suggest relevant features regarding the efficiency of computer-based treatments, and offer insights into improving computer-aided psychological interventions.Este estudio analiza las preferencias de los participantes sobre tres tratamientos de exposición basados en ordenador para el miedo a volar (MV): tratamiento de exposición mediante realidad virtual asistido por un terapeuta (RV), tratamiento de exposición asistido por ordenador con un terapeuta durante la exposición (CAFT-T) y tratamiento de exposición asistido por ordenador autoaplicado (CAFT-A). 60 participantes con MV fueron asignados aleatoriamente a uno de estos tratamientos. Al final del tratamiento, los participantes veían una demostración de las otras dos opciones y valoraban sus preferencias. En el post-tratamiento, la evaluación de las preferencias se obtuvo para 48 participantes (CAFT-T n= 14; CAFT-A n= 16 y RV n= 18). Los participantes valoraron la RV como la más eficaz, más recomendada, pero también como la más aversiva. Atendiendo a la condición de tratamiento recibida, en las condiciones RV y CAFT-T los participantes valoraron su propio tratamiento como el más preferido, más eficaz y más recomendable. Los resultados sugieren aspectos relevantes sobre la eficiencia de los tratamientos basados en ordenador y ofrecen ideas para mejorar las intervenciones psicológicas asistidas por ordenador.Funding for the study was provided by grants SEJ-2006-14301/PSIC, PROMETEO/2008/157 and PSI2010-17563 from the Spanish Government; Generalitat Valenciana, Conselleria de Educación Proyecto PROMETEOII/2013/003 para grupos de excelencia, and CIBER Fisiopatología de la Obesidad y Nutrición (CB06/03) is an initiative of ISC-III
