Construcción y validación de la escala de conductas sobre sexting (ECS)

ABSTRACTThe aim of this paper was to construct and validate the Escala de Conductas sobre Sexting (ECS) (by the absence of standardized procedures for evaluating behaviors related to the sending and receiving sexts -text messages or images with provocative or sexual content- through the mobile phone and social networks) (Dir, Cyders y Coskunpinar, 2013), with a sample of 985 Spanish university students. Firstly, a pilot study was made with 110 university students, showing a good internal consistency (α = .923) and allowing to execute the initial adjustments and modifications. To confirm the relationship between the items, the sample, randomly selected, was divided into two. An exploratory factorial analysis, with Varimax rotation in the first subsample, showed a significant relationship between the items and a good internal consistency (α = .922), retaining three factors that explained the 66.406% of the variance. Finally, a confirmatory factorial analysis carried out with the second subsample, revealed a good fit of the model. On the other hand, the Goodness of Fit Index (GFI) and the Adjusted Goodness of Fit Index (AGFI) offered values of .919 and .854, respectively; while the average of the Root Mean Square Error of Approximation (RMSEA) showed a value of .061. All these data lead to the conclusion that the ECS seems to be a valid and reliable scale to evaluate the sexting behaviors in this population.RESUMENEl objetivo de este estudio ha sido la construcción y validación de la Escala de Conductas sobre Sexting (ECS) (ante la ausencia de procedimientos estandarizados que permitan evaluar conductas relacionadas con el envío y recepción de sexts -mensajes de texto o imágenes con contenido provocativo o sexual- a través del teléfono móvil y de las redes sociales) (Dir, Cyders y Coskunpinar, 2013), en una muestra de 985 universitarios españoles. En primer lugar se realizó un estudio piloto con 110 estudiantes mostrando buena consistencia interna (α = .923) y permitiendo efectuar los primeros ajustes y modificaciones a la escala. Para confirmar la relación entre los ítems, se procedió a dividir la muestra, seleccionada aleatoriamente, en dos. Un análisis factorial exploratorio, con rotación Varimax sobre la primera submuestra, mostró una relación significativa entre los ítems con una consistencia interna adecuada (α = .922), reteniendo tres factores que explican el 66.406% de la varianza. Finalmente se comprobó la validez de constructo mediante un análisis factorial confirmatorio sobre la segunda submuestra, que reveló buen ajuste del modelo. Por otro lado, el índice de bondad de ajuste (GFI) y el corregido (AGFI) ofrecieron valores de .919 y .854, respectivamente, mientras que el promedio de los residuales estandarizados (RMSEA) arrojó un valor de .061.  Estos datos permiten concluir que la escala construida (ECS) parece ser un instrumento válido y fiable para evaluar las conductas de sexting en esta población.ABSTRACTThe aim of this paper was to construct and validate the Escala de Conductas sobre Sexting (ECS) (by the absence of standardized procedures for evaluating behaviors related to the sending and receiving sexts -text messages or images with provocative or sexual content- through the mobile phone and social networks) (Dir, Cyders y Coskunpinar, 2013), with a sample of 985 Spanish university students.
