Evidence and perspectives from Spain: Findings from research on the Spanish translation of the SIS-A and SIS-C

Abstract

[EN]The assessment of support needs has gathered much attention over the last few years in the field of intellectual disabilities, becoming a key aspect for the implementation of individualised support plans. This work is aimed to present findings from research on the Spanish adaptation of the Support Intensity Scale for Adult (SIS-A) and for Children (SIS-C) in Spain. The SIS-C adaptation process (n=814; aged 5-16) was linked to the SIS-A previously conducted (n=885; 16-64 years old). Some extra analyses were also included considering item response theory and comparisons with the ordinary support needs of sutdents without disabilities. Both SIS-A and SIS-C obtained a Cronbach's Alpha > .99; tst-retest reliability > .94 and inter-rater reliability > .80. The confirmatory factor analysis showed proof of validity based on the correlational structure of the scale. Some minor problems in the SIS-C discrimination validity were found. Given the lack of instruments to assess support needs in Spain, SIS-A and SIS-C are promising and powerful tools to facilitate the implementation of individualised support plans. However, more research is needed.
