Cross-Cultural Preliminary Validation of a Measure of Social Vulnerability in People with Intellectual Disabilities

Background: Social vulnerability refers to the ways in which an individual is at risk of being victimised. The Test of Interpersonal Competences and Personal Vulnerability [TICPV] is an Australian assessment tool designed for adults with intellectual disabilities (ID) [Wilson et al. (1996). Vulnerability to criminal exploitation: Influence of interpersonal competence differences among people with mental retardation. "Journal of Intellectual Disability Research," 40, 8-16. https://doi.org/10.1111/j.1365-2788.1996.tb00597.x]. It aims to evaluate their social vulnerability. This study aims to conduct a preliminary cross-cultural validation of the TV-22, the French-language, enhanced and accessible version of the TICPV. Method: Twenty-nine French-speaking adults with ID answered the TV-22. The reliability and validity of this measure were assessed. Results: Performance on the test was shown to be internally consistent (Cronbach's [alpha] = 0.89; McDonald's [Omega] = 0.93), stable over time (r[subscript s](29) = 0.81, p <0.01) and a valid measure of social vulnerability. Conclusions: Results provide psychometric support for the use of the TV-22. Further research is needed to confirm these results with a larger sample.
