Validation of the French Translation of the SOSI-M

The aim of this study is to validate the French version of the SOSI-M test on healthy children as well as on children with neurodevelopmental disorders (NDDs).

Therefore, the investigators will conduct a video recording of the test administration on a group of healthy children and on a group of children with NDDs.

The research question is: Is the French translation of the SOSI-M test equivalent, in terms of functionality and expected results, to the original version for a population of healthy children and children with mild to moderate neurodevelopmental disorders?

The hypothesis is that the psychometric properties of the French version are similar to those of the original version.

Secondly, the investigators will investigate: Does the difference in socio-cultural context between healthy Belgian and Senegalese children influence the SOSI-M score?

The hypothesis is that healthy Belgian children obtain better scores compared to healthy Senegalese children.

The scores of the two groups will be compared with each other and with those obtained in previous studies. Intra- and inter-rater reliability will also be assessed.

Only the study team can determine whether someone qualifies for participation.

For the groupe of children with neurodevelopmental disorders :

Inclusion criteria

neurodevelopmental disorder (NDD)
speak french and understand instructions in French
and have not been assessed with the SOSI-M in the past 6 months.

Exclusion criteria

Severe motor/cognitive impairment
uncorrected visual/auditory impairment
cerebral palsy diagnosis

For the neurotypical children :

Inclusion criteria

speak french and understand french instructions

Exclusion criteria

diagnostic of musculoskeletal condition or neurodevelopmental or neurological condition
health condition that contraindicates taking the SOSI-M

Treatment and study plan

Administration of the French translation of the SOSI-M test.

Diagnostic Test

Filmed administration of the French translation of the SOSI-M test

We will then compare the scores of the two groups between them and with the scores obtained by other studies.

There will be two operators that will evaluate each video 2 times (3 weeks between each evaluation) in order to mesure the metrologics qualities like fidelity.

Primary outcomes

SOSI-M score

Time frame: 1 day for the filmed passation of the french version of the sosi-m test.

For the total raw score :

0 = Abnormal 64 = Normal development of the child
