Abstract :Background and aims: The current study aimed to evaluate the psychometric properties of a Turkish version of The Nine Item Avoidant/Restrictive Food Intake Disorder Screen Parent Report insert ignore into journalissuearticles values(NIAS-PR);, which measures the avoidant/restrictive food intake disorder insert ignore into journalissuearticles values(ARFID); symptoms by parents. NIAS-PR includes three subscales picky eating, poor appetite/limited interest in eating, and fear of aversive consequences from eating. Also, our secondary aim was to assess the relationship between ARFID-related eating behaviours and emotional-behavioural symptoms of children and parents\` psychological status. Methods: The NIAS-PR was translated into Turkish with standard procedures. Two hundred sixty-eight children insert ignore into journalissuearticles values(133 girls, 49.6%; mean age 8.62, age range from 2 to 18 years); and parents insert ignore into journalissuearticles values(175 mothers, 65.2%); were included in the study. The factor structure was confirmed using confirmatory factor analysis insert ignore into journalissuearticles values(CFA);. The results were compared to the validated Turkish Children’s Eating Behavior Questionnaire insert ignore into journalissuearticles values(CEBQ); to determine the convergent validity. Internal consistency insert ignore into journalissuearticles values(Cronbach alpha coefficient); analysis was used to determine the reliability of the NIAS-PR. Results: The current study provided evidence for the validity of the translated Turkish version of the NIAS-PR in the pediatric population. The three-factor structure of the NIAS—Picky eating, Appetite, and Fear—was replicated in the Turkish NIAS-PR. The NIAS-PR subscales showed the expected patterns of correlations with the CEBQ subscales. The reliability of the Turkish version of NIAS-PR proved to be satisfactory insert ignore into journalissuearticles values(total Cronbach\`s alpha=0.90); in the pediatric population insert ignore into journalissuearticles values(2-18 years);. Conclusions: This study demonstrated a good internal consistency of the Turkish version of the NIAS-PR. We confirmed the three-factor structure of the Turkish version of NIAS-PR. NIAS-PR is a brief, reliable instrument for ARFID research in Turkish children and adolescents. The NIAS-PR is developed as a screening questionnaire, so health professionals should use it to investigate ARFID-related eating behaviours further. It is worth mentioning that deepening these eating symptoms with clinical interviews is necessary.
