Eligibility

Primary outcome measure(s)

• Gastrointestinal symptoms — Baseline and 3 months
  It will be evaluated whether there is a difference in the effects of the gluten-free-casein-free diet and the Feingold Diet on the gastrointestinal system. The evaluation will be made using the Gastrointestinal Sensitivity Index. Gastrointestinal Sensitivity Index: The GI sensitivity index assesses 0-17 points. A score of seven and above is a severe symptom in the child. The Gastrointestinal Sensitivity Index is applied by hospital personnel. It was prepared to examine children's digestive problems and their changes according to periods. The test consists of nine headings under the heading of symptoms: "Constipation, Diarrhea, Average Stool Density, Abdominal Hardness, Stool Odor, Flatulence, Abdominal Pain, Unexplained Daytime Irritability, Nighttime Awakening, and Abdominal Hardness." Each heading was matched with the answers numbered "0, 1, 2" and the sensitivity index was obtained.
• Eating behaviors — Baseline and 3 months
  It will examine whether there is a difference between the effects of the gluten-free-casein-free diet and the Feingold Diet on eating behavior. Brief Autism Mealtime Behaviors Inventory (BAMBI): It was adapted into Turkish by Meral and Fidan in 2014. The scale consists of 18 items. It consists of three subscales: limited food variety, refusal, and autism-related behavioral characteristics. Items 3, 9, 10, and 15 are reverse-scored. Each item is scored as 1 for never, 2 for rarely/rarely, 3 for occasionally/sometimes, 4 for often, and 5 for always, according to its frequency of occurrence. The BAMBI-total score and subscale scores are as follows: For the limited food variety score, the total score of items 10, 11, 13, 14, 15, 16, 17, and 18 is evaluated; for the food refusal score, the total score of items 1, 2, 4, 7 and 8 is evaluated; and for the autism-specific behavior score, the total score of items 3, 5, 6, 9 and 12 is evaluated. High scores from the total and subscales indicate
• Pediatric Quality of Life — Baseline and 3 months
  It will examine whether there is a difference between the effects of the gluten-free-casein-free diet and the Feingold Diet on quality of life. The Pediatric Quality of Life Inventory (PedsQL): The Children's Quality of Life Questionnaire (PedsQL) was developed by Varni and colleagues in 1999 to assess the health-related quality of life of children and adolescents between the ages of 2 and 18. The scale has four separate forms organized according to age group characteristics for the 2-4, 5-7, 8-12, and 13-18 age groups. The Turkish validity and reliability studies of the forms for the 5-7 age group were conducted by Üneri et al., and the Turkish validity and reliability studies of the forms for the 8-12 and 13-18 age groups were conducted by Memik et al. The scale, which has a parent-only form for the 2-4 age group, has both parent and child forms for other age groups. The scale has four subscales that question physical, emotional, social, and school-related functionality. While a fi
