Picky eating in children is often a major source of concern for many parents and caregivers. Picky eaters (PEs) consume limited foods, demonstrate food aversion, and have a limited food repertoire, which hinders their growth and health. These behaviours are common in children with special health care needs despite the rise in typically developing children. This leads to less attention being given to intervention programmes for typically developing children. Therefore, this scoping review aims to investigate the key concept of an existing intervention programme for PE among typically developing children, primarily on the types and approaches selected. A thorough literature search was conducted on three primary databases (PubMed, Emerald In-sight, and Web of Science) using predefined keywords. The literature was then appraised using the Joanna Briggs Institute’s guidelines and protocols, and the PRISMScR checklist. Inclusion and exclusion criteria were also specified in the screening procedure. Results showed that the majority of the interventions in these studies were single-component interventions, with the sensory approach being the type that was most frequently utilised, followed by the nutrition approach and parenting approach. Single and multiple intervention components improved the assessed outcome, with a note that other components may or may not show a similar outcome, as they were not assessed in the single-component intervention. Given the evidence that picky eating is influenced by various factors, a multi-component intervention can provide a substantial impact on future programmes. In addition, defining picky eaters using standardised tools is also essential for a more inclusive subject selection.

Nutritional status of people with intellectual disability (PWID) is always at risk and developing a dietary assessment tool is important. This study aims to test reliability (inter-rater reliability and test-retest reliability) and comparable validity (limit of agreement against a multiple pass 24-hour diet recall recorded by a professional dietitian) of a recently developed dietary assessment kit, CIDDIE Kit©, that specialised for a more dependent group of PWID, focusing on preschool aged children. The CIDDIE Kit© was given to 26 parents or caretakers of children with intellectual disabilities (ID) registered with three selected Community Based Rehabilitation Centre in the Klang Valley area. Each subject was asked to complete two sets of CIDDIE Kit© in a two-week interval session. Meanwhile, a certified dietitian conducted a 24-Hour Diet Recall among the same 26 subjects. The validity and reliability of CIDDIE Kit© were analysed using Bland-Altman method, percentage of correctly classified quartile, Intra-class Correlation Coefficient (ICC) value and Pearson’s correlation coefficient. For comparable validity test, the estimated intake from CIDDIE Kit© and Multiple Pass 24-Hour Diet Recall were considerably in agreement to each other. The test-retest reliability analysis showed significant high similarity (p < 0.001) between the estimated intake from both phases of CIDDIE Kit© where the ICC value ranged approximately 0.9 (R = 0.889 - 0.930). The inter-rater reliability analysis was significantly positive (p < 0.001) and strong correlation (indicating internal consistency), r (0.706 – 0.853). The specially designed CIDDIE Kit© can provide a considerably valid and reliable assessment.
