EMDR Therapy in Young Children, a Double-blinded Randomized Controlled Trial

diagnostic of 13 pathologies, such as post Traumatic stress disorder (PTSD) or others stress related disorders, Anxiety related disorders, and associated disorders. This tool as 517 items. This scale doesn't work on numerical values (there is no min, max or cut scores), this scale makes it possible to confirm or invalidate the presence of symptoms necessary for establishing diagnoses on Diagnosis and Statistical Manual of Mental Disorders (DSMV) criteria.

symptoms of anxiety is measure by Preschool Anxiety Scale (PAS) The PAS is a heteroevaluation (for parents or the main care figure) to assess symptomatology of anxiety in children aged 3 to 6 years. This tool has 34 items, based on a 5-points Likert scale, each item is scored from 0 to 4, the PAS has a score ranging from 0 to 112. To interpret this questionnaire, T-scores must be used. T-Scores enable the comparison of a child scores against norms from an equivalent age and gender group from a representative normative sample.

symptoms of parental distress and parent-child dysfunctional interaction is performed by Parental Stress Index Screening Form (PSI-SF). The "Parental Stress Index Short Form" is a self-assessment intended for the child's parent The PSI-SF has 36 items from the original 120-item PSI and based on a 5-points Likert scale, each item is scored from 1 to 5, the PSI-SF has a score ranging from 36 to 180. Percentile scores are used to interpret the scores.

Scores at or above the 85th percentile are considered high (normal range : 15th-80th percentile)

measure of symptoms of PTSD by Young Child Post-traumatic Stress Disorder Checklist.

This scale aims to screen for post-traumatic stress disorder symptoms in children aged 1 to 6 years old, by evaluating traumatic exposures (13 items), symptoms presented by the child (23 items) and his level of impairment or functional impairment (6 items). Items 14 to 36 relate to symptoms of PTSD and are based on a 5-points Likert scale, each item is scored from 0 to 4, the YCPC has a score ranging from 0 to 92. The diagnosis Cutoff is at 26 or more for items 14-36, it indicates a "probable diagnosis" of PTSD. Items 37 to 42 study functional impairment. These items scores can be added together to form a disability score, but they are not used in the PTSD symptom score

pathologic behaviors are measured by Child Behavior Checklist " (CBCL) ;

The Child Behavior Checklist assesses anxiety, depression, emotional dysregulation, sleep disorders, attention problems, withdrawal behavior, and aggressive behavior. This list of items initially used with children aged 6 to 18 has been adapted for preschoolers. The study plans to use the preschool form (CBCL/ 1.5-5) for children aged 3 years to 5 years and 11 months, and the original CBCL for children aged 6 years to 6 years and 11 months.

The Checklist is based on a 3-points Likert scale, each item is scored from 0 to 2, the CBCL has a score ranging from 0 to 230.

To interpret this questionnaire, T-scores must be used.

use of French version of the Wechsler Preschool and Primary Scale of Intelligence ; only the subtests: Picture naming - for children ages 3 to 6 years ; Matrix - for children ages 4 to 6 years; Pictures Memory - for children ages 3 to 3 years and 11 months; Spatial Memory (Zoo location)- for children ages 3 to 6 years;

The Wechsler Preschool and Primary Scale of Intelligence (WPPSI) is a cognitive assessment of children aged 2 years and 6 months to 7 years and 7 months. The 4th revision makes it possible to take into account the major stages of the child's cognitive and neurological development. Only subtests that show how the child develops certain major cognitive functions will be administered

cognitive functioning (executive functioning) measure by french test of Executive Function Assessment Battery for Preschoolers named " La batterie d'évaluation des fonctions exécutives pour enfants d'âge préscolaire " (BEFEX-P) version 4.0 - (Monette & Bigras, 2017)

This evaluation includes two independent tests: a Stroop test adapted to the child, and a tracing tracks. The Stroop fruit is an evaluation of inhibition and flexibility functions in preschool children which is practiced in verbal condition.

Trace tracing is a cognitive task that allow the evaluation of executive functions (inhibition and flexibility) in preschool children.

cognitive functioning (autobiographical memory) measure with french test of Autobiographical Memory Evaluation Task named " Tâche d'Evaluation de la Mémoire Autobiographique " (TEMA ; Deplus, de Romree, & Van Broeck, 2013)

The TEMA assessment evaluates the functioning of autobiographical memory in preschool children (children from 3 years to 5 years and 11 months). This test makes the child do exercises to produce autobiographical memories.
