Neuropsychologist since 2004, I have followed a double curriculum in research and in clinical neuropsychology. I had the chance to combine my two passions by joining the clinical research structure of the Hospices Civils de Lyon in 2011. I joined the team who developed international functional assessment tools in France, like the Vineland II. I’m a part of the Filière DefiScience team and since 2020 I have been working in the Autism Ressource Center (Lyon). My missions cover the fields of diagnosis in Neurodevelopmental Disorder, tools training, and multidimensional evaluations in intellectuals disorders.

ABSTRACT

Introduction

For populations with intellectual disability and autism spectrum disorder, it is essential to complete cognitive assessment with an adaptive behavior scale.

Objectives

To translate VABS-II from English to French and establish norms for the French population.

Methods

We used the Parent/Caregiver form in order to assess psychometric characteristics of the VABS-II and to develop norms for the French population. VABS-II comprises 4 domains, 11 subdomains, and an optional maladaptive behavior index. The French translation of the VABS-II followed standard cross-cultural translation methods. The study was performed in the Rhône-Alpes-Auvergne department comprising 12 % of France inhabitants and well representing the French general population.

Results

From 4576 VABS-II questionnaires distributed, 1707 were returned and 1654 were analyzed. The reason for exclusion was the impossibility to score one of the subdomains. From 174 questionnaires included in the test-retest, 95 were analyzed, and 79 questionnaires were excluded because 86 under 34 days, 8 > 3 months, and one participant that changed age group between test and retest. Scores based on French norms fluctuated around values based on US norms on all subdomains.

Conclusions

The French Vineland questionnaire is the single test with the adequate norms to allow identifying children with adaptive behavior difficulties. It should be used as a complement of the assessment of the intellectual quotient, according to DSM V, for the diagnosis of intellectual disabilities. It must be done in reference to the developmental and cultural standards specific to the environment in which the person is evolving.
