          ABSTRACT

          Background: Intrusive memories form a core symptom of Posttraumatic Stress Disorder (PTSD). Based on concepts of visuospatial interference and memory-updating accounts, technological innovations aim to attenuate such intrusions using visuospatial interventions.

          Objective: This study aims to test the effect of a visuospatial Tetris-based intervention versus a verbal condition ( Wiki) and a never-targeted control ( no intervention) on intrusion frequency.

          Method: A randomized crossover trial was conducted including N = 38 PTSD patients who had at least 3 distinct intrusive memories of trauma. After both 2 weeks (intervention 1) and 4 weeks (intervention 2), one of the three memories was randomly selected and either the visuospatial intervention (memory reminder of a traumatic memory + Tetris) or verbal condition (reading a Wikipedia article + answering questions) was performed on their first memory in randomized order. In the week 4 session, the patient conducted the other intervention condition on their second memory (crossover). The third memory was never targeted ( no intervention). Daily occurrence of intrusions over 8 weeks was collected using a diary and analysed using mixed Poisson regression models.

          Results: Overall, there was no significant reduction in intrusion frequency from either intervention compared to each other, and to no intervention control (relative risk Tetris/ Wiki: 0.947; p = .31; relative risk no intervention/ Tetris: 1.060; p = .15; relative risk no intervention/ Wiki: 1.004; p = .92).

          Conclusions: There was no effect of either intervention on intrusions when administered in a crossover design where participants received both interventions. Design shortcomings and consequences for future studies are discussed.

          HIGHLIGHTS

          • Visuospatial interventions, including the computer game Tetris, have been studied as a potential means to decrease intrusive memories, a core feature of Posttraumatic Stress Disorder.

          • In this study, two interventions are tested in a crossover design with patients with intrusive memories after traumatic experiences.

          • There was no effect of either the visuospatial intervention or the verbal condition in this design.

          Antecedentes: Los recuerdos intrusivos constituyen un síntoma central del Trastorno de Estrés Postraumático (TEPT). Basándose en conceptos de interferencia visoespacial y capacidad de actualización de la memoria, las innovaciones tecnológicas buscan como objetivo atenuar tales intrusiones, utilizando intervenciones visoespaciales.

          Objetivo: Este estudio tiene como objetivo evaluar el efecto de una intervención visoespacial basada en el Tetris, en comparación con una condición verbal (Wiki) y un grupo control sin intervención (ninguna intervención), sobre la frecuencia de las intrusiones.

          Método: Se llevó a cabo un ensayo aleatorizado cruzado, que incluyó N = 38 pacientes con TEPT, que tenían al menos 3 recuerdos intrusivos distintivos de trauma. Después de 2 semanas (intervención 1) y 4 semanas (intervención 2), se seleccionó al azar uno de los tres recuerdos y se realizó la intervención visoespacial (recordatorio de un recuerdo traumático + Tetris) o la condición verbal (lectura de un artículo de Wikipedia + responder preguntas) realizado sobre su primer recuerdo en orden aleatorio. En la sesión de la semana 4, el paciente realizó la otra condición de intervención (cruzado), sobre su segundo recuerdo. El tercer recuerdo nunca fue intervenido (sin intervención). La ocurrencia diaria de intrusiones durante 8 semanas se recopiló mediante un diario y se analizó utilizando modelos de regresión mixtos de Poisson.

          Resultados: En general, no hubo una reducción significativa en la frecuencia de las intrusiones a partir de ninguna de las intervenciones comparadas entre sí, y tampoco con el control sin intervención (riesgo relativo Tetris/Wiki: 0.947; p = .31; riesgo relativo sin intervención/Tetris: 1.060; p = .15; riesgo relativo sin intervención/Wiki: 1.004; p = .92).

          Conclusiones: No hubo un efecto en ninguna de las intervenciones sobre las intrusiones, cuando se administraron en un diseño cruzado donde los participantes recibieron ambas intervenciones. Se discuten las deficiencias del diseño y las consecuencias para estudios futuros.

            Research electronic data capture (REDCap)--a metadata-driven methodology and workflow process for providing translational research informatics support.

            Research electronic data capture (REDCap) is a novel workflow methodology and software solution designed for rapid development and deployment of electronic data capture tools to support clinical and translational research. We present: (1) a brief description of the REDCap metadata-driven software toolset; (2) detail concerning the capture and use of study-related metadata from scientific research teams; (3) measures of impact for REDCap; (4) details concerning a consortium network of domestic and international institutions collaborating on the project; and (5) strengths and limitations of the REDCap system. REDCap is currently supporting 286 translational research projects in a growing collaborative network including 27 active partner institutions.

              The REDCap consortium: Building an international community of software platform partners

              The Research Electronic Data Capture (REDCap) data management platform was developed in 2004 to address an institutional need at Vanderbilt University, then shared with a limited number of adopting sites beginning in 2006. Given bi-directional benefit in early sharing experiments, we created a broader consortium sharing and support model for any academic, non-profit, or government partner wishing to adopt the software. Our sharing framework and consortium-based support model have evolved over time along with the size of the consortium (currently more than 3200 REDCap partners across 128 countries). While the "REDCap Consortium" model represents only one example of how to build and disseminate a software platform, lessons learned from our approach may assist other research institutions seeking to build and disseminate innovative technologies.
