- Brief Summary
Food selectivity is a common challenge among children with Autism Spectrum Disorder (ASD), with significant impacts on their nutrition and well-being. The main purpose of this study is to promote children's active participation in mealtime routines and encourage experimentation with new foods through an approach that emphasizes joy and serenity during mealtimes. The study will involve children with ASD between the ages of 4 and 10 years, of both sexes. Food selectivity will be assessed through interviews with parents and the use of specially created cards.
The protocol will include 45-minute sessions, twice a week, for a total of 48 sessions. During these sessions, two plates, a list of foods previously agreed upon with the parents, and the foods needed for each session will be used. The sessions will take place in an environment called "Home Lab"a specially set up as if it were a kitchen to reproduce a home atmosphere.
- Detailed Description
Food selectivity training is divided into three steps. Step 1- Pairing in the kitchen. Propose highly enjoyed activities to the child in the kitchen. Criterion for moving to step 2: Child stays in the kitchen to play for 5 minutes for 3 consecutive sessions.
Indicate the minutes of playing in the kitchen.
Step 2 Food selectivity training is divided into three steps. Step 1- Pairing in the kitchen. Propose highly enjoyed activities to the child in the kitchen. Criterion for moving to step 2: Child stays in the kitchen to play for 5 minutes for 3 consecutive sessions.
Indicate the minutes of playing in the kitchen. Step 2 At the beginning of the session prepare two identical plates, in each plate there will be 6 foods, arranged in the same way. Place them on the table in the kitchen.
Training
* Transition living room (carpet) - kitchen (table)
* The child is participating in a welcome game with the operator;
* the operator waits 30 sec for the child to spontaneously interact with him: he approaches, stands up and tries to take the operator's hand
* Immediately afterwards, the operator accompanies the child to the kitchen.
* If the child does NOT spontaneously interact with the operator within 30 sec then says, "Let's go."
* If the child does NOT follow the operator's prompt within 30 sec, the operator repeats the prompt once. If the child does not follow the prompt the session will be postponed until the next day.
* NB: If the latter situation occurs (the child does not follow the prompt and therefore the session is postponed) note what happened.
* Procedure
* the operator sits next to the child(ren);
* the operator interacts with the food, without eating it (e.g., touches it, smells it ...).
* During the session, the operator maintains a positive expression, talks about general topics not related to food.
* the practitioner does NOT give any prompt to the child to taste or eat the food.
* The child can walk away at any time. Criterion for moving to stage 3: Child remains seated with plate in front of him/her for 30 sec without emitting problem behaviors for 3 consecutive sessions.
Indicate the time (seconds) in which the child remains sitting with the plate in front of him without stress.
Step 3 - Shaping
- At the beginning of the session prepare two identical plates, in each plate there will be 6 foods, arranged in the same way. Place them on the table in the kitchen.
* Operator inserts comments about the food (e.g., "these carrots are delicious").
* The operator prepares a small container with small pieces with the child's favorite food. The favorite food should only be available at the shaping stage. The container with the favorite food must be out of the child's reach but must be visible to him. The favorite food should not be in the saucer, even in stage 2.
* The caregiver observes any food-related behavior of the child (for example: looks at it, touches it ...). If the child emits any food-related behavior the operator immediately reinforces by praising it and giving it a piece of the favorite food.
The operator defines the target behaviors to be reinforced.
* If the child does not emit any target behavior for more than 15 sec, the operator selects a different target behavior.
* If the child shows any negative emotion at any time during the session, the operator immediately changes the target behavior. To encourage the emergence of different behaviors, the practitioner will differentially reinforce the child's responses. The experimental group will conduct the protocol activity in pairs, and the control group individually.

- Primary Outcome Measures
Name Time Method inventory of food preferences The test need approximately 20 minutes The food preference inventory includes a list of foods that is submitted to the parent. Asked how often the food is consumed by the child and family
Brief Autism Mealtime Behavior Inventory (BAMBI) The test need approximately 10 minutes the Bambi measures food selectivity, disruptive behavior, food refusal and rigidity at mealtime
The 18-item Brief Autism Mealtime Behavior Inventory (BAMBI) is a parent-report questionnaire that was created to identify mealtime habits unique to kids with ASD.
The BAMBI is rated on a Likert scale of 1 to 5, where 1 represents "never" occurring behavior during mealtime and 5 represents "always" occurring behavior. For four of the items that rate constructive mealtime behaviors, reversed scoring is applied. The sum of the 18 elements is used to create the total frequency score, with higher scores indicating more issues with behavior during meals.general assessment checklist The test need approximately 15 minutes the general assessment includes a personal data sheet, the section relating to nutrition and therefore to the dietary regime, the type of selectivity and dysfunctional behaviours. Finally there is the adaptive functioning card relating to autonomy during meals.
