Estimating sexual knowledge of people with mild intellectual disability through a valid and reliable assessment scale: The ISK-ID.

BACKGROUND: Despite the relevance of assessing sexual knowledge in people with Intellectual Disability, there is a lack of appropriate assessment tools to measure this domain. The current study tests the psychometric properties of the new 'Inventory of Sexual Knowledge of people with Intellectual Disability' (ISK-ID). METHOD: 345 individuals with mild intellectual disability completed the ISK-ID before and after the implementation of a sexual education program. Psychometric properties of the ISK-ID were analysed according to Multidimensional Item Response Theory (MIRT). RESULTS: Its underlying factorial structure, along with parameters derived from the MIRT (item discrimination, difficulty, and participant's ability), support the use of the ISK-ID as a measure of sexual knowledge. Moreover, the ISK-ID was able to detect changes in the level of sexual knowledge resulting from educational interventions (i.e., responsiveness). CONCLUSIONS: The ISK-ID is an appropriate assessment tool to measure sexual knowledge in men and women with mild intellectual disability.

Análisis comparativo de la eficacia de un programa lúdico-narrativo para la enseñanza de las matemáticas en Educación Infantil / Comparative analysis of the efficacy of a playful-narrative program to teach mathematics at pre-school level

El objetivo de este estudio es comprobar la efectividad de un programa basado en una metodología lúdico- narrativa para consolidar los contenidos y competencias matemáticas en Educación Infantil en comparación con otras metodologías utilizadas actualmente. Para ello, se seleccionaron 100 niños de 5-6 años que fueron divididos en tres condiciones experimentales: la metodología tradicional basada en fichas de trabajo (centros de interés); una metodología que incluye elementos visuoperceptivos de estimulación temprana y manipulativos, y una metodología que incluye componentes lúdicos y narrativos. Los instrumentos de evaluación utilizados han sido una prueba criterial de matemáticas para Educación Infantil validada en nuestro contexto y el subtest de conceptos cuantitativo-numéricos de BADyG. Los sujetos fueron evaluados antes y después del curso académico a lo largo del cual trabajaron siguiendo una de estas tres metodologías. Los resultados muestran que el programa basado en componentes lúdicos y narrativos se muestra más eficaz que las otras dos condiciones metodológicas con las que se compara (p<.000***). Se analizan las implicaciones que estos resultados tienen para las prácticas instruccionales (AU)

In this paper, the effectiveness of a programme comprising several components that are meant to consolidate mathematical concepts and abilities at the pre-school level is analyzed. The instructional methodology of this programme is compared to other methodologies. One-hundred 5-6 year-old children made up the sample that was distributed in the following conditions: (1) traditional methodology; (2) methodology with perceptual and manipulative components, and (3) methodology with language and playful components. Mathematical competence was assessed with the Mathematical Criterial Pre-school Test and the subtest of quantitative-numeric concepts of BADyG. Participants were evaluated before and after the academic course during which they followed one of these methodologies. The results show that the programme with language and playful components is more effective than the traditional methodology (p<.000) and also more effective than the perceptual and manipulative methodology (p<.000). Implications of the results for instructional practices are analyzed (AU)
