Sensory Feeding and Parent Coaching for Children With ARFID

Condition(s) studied

Investigational drug(s) / intervention(s)

Sequential Oral Sensory (SOS) Feeding Approach: The SOS Feeding Approach is a structured, evidence-informed intervention that gradually exposes children with ARFID to food across multiple sensory dimensions, recognizing that these children often experience heightened sensitivities to textures, smells, and tastes that can trigger avoidance and distress. Unlike traditional behavioral methods that focus primarily on intake, SOS emphasizes building comfort, positive associations, and sensory tolerance before progressing to consumption. Delivered in 12 weekly 60-minute sessions by trained occupational therapists, the approach is individualized to each child's developmental stage, medical history, and swallowing safety, with foods selected accordingly. Sessions progress through a hierarchy-visual tolerance, olfactory exposure, tactile exploration, oral contact, intraoral exploration, and finally chewing and swallowing-ensuring gradual, non-coercive acceptance. By integrating sensory-motor learning with feeding, the intervention reduces m

SOS + Occupational Performance Coaching (OPC): In the combined SOS and OPC intervention, children receive a 60-minute SOS session each week for 12 weeks, immediately followed by a 30-minute OPC session with their parents. SOS targets the child's sensory tolerance and positive engagement with food, while OPC uses a semi-structured coaching format where parents set meaningful feeding goals, analyze mealtime routines, and develop sustainable strategies with the therapist. Parents implement these strategies at home and review progress in subsequent sessions, ensuring continuous feedback and adjustment. This dual approach is distinguished by its family-centered nature, empowering parents as active agents of change, and by its integration of child-focused sensory therapy with parent coaching to reinforce improvements across home and clinical settings. By addressing both sensory challenges and parent-child dynamics, the intervention aims to reduce mealtime anxiety, expand food acceptance, strengthen parental self-efficacy, and achieve mor

OPC Group: Occupational Performance Coaching (OPC) is a evidence-based, family-centered coaching intervention developed by Dr. Fiona Graham (University of Otago, NZ). OPC enables parents to identify meaningful participation goals, analyze performance barriers, and develop their own strategies to support their child's daily functioning. OPC is structured around three enabling domains: Connect (building a trusting therapeutic partnership), Structure (collaborative performance analysis and goal-directed action), and Share (facilitating reflection and knowledge exchange). Sessions are delivered in a semi-structured interview format by an occupational therapist. In this study, OPC will be delivered once weekly for 12 weeks (30-minute individual sessions). Focus areas include feeding routines, parent-child mealtime interaction, home-based implementation strategies, and parental self-efficacy. The primary outcome will be measured using the Goal Assessment Scale (GAS)

Waitlist: The 15 children on the waiting list will be selected as a control group. These children will undergo an initial assessment, and no intervention will be applied for 12 weeks. Final test measurements will be taken at the end of the 12 weeks. After the study is completed, the effective intervention method will be applied to these children in the same manner, completely independent of the study.

Study summary

This study aims to investigate the effects of the SOS approach alone, or the SOS approach plus the OPC intervention, on children's feeding problems and feeding behaviors, as well as parents' feeding attitudes and mealtime behaviors in children diagnosed with ARFID. This randomized, single-blind, controlled trial will be conducted with children aged 3-8 years who were diagnosed with ARFID by a Child and Adolescent Psychiatrist according to DSM-V criteria and referred to an occupational therapy department. Power analysis determined the sample size to be 45 children (15 per group). Participants will be assigned to three groups using computer-assisted block randomization: Group 1: Sequential Oral Sensory (SOS) Feeding Approach alone; Group 2: SOS approach plus Occupational Performance Coaching (OPC); and Group 3: Control group (standard follow-up without intervention). The study design will utilize the Consort checklist used for randomized controlled trials. Informed consent will be obtained from participants. Pre- and post-intervention assessments will be conducted on the child's feeding behaviors, food variety, and mealtime negative behaviors, as well as parental feeding attitudes, mealtime behaviors, and stress. The study concludes that feeding interventions implemented using the SOS approach will be effective in reducing food acceptance, food variety, and mealtime negative behaviors in children with ARFID. These effects are expected to be more pronounced and sustained when Occupational Performance Coaching (OPC) is added to the SOS approach. Furthermore, positive changes in parents' feeding attitudes and strengthened parent-child interactions at mealtime are anticipated. These results will contribute to the literature on the effectiveness of using sensory-based approaches and family-based counseling in combination in interventions for ARFID. They are also expected to provide an evidence-based roadmap for occupational therapists to develop holistic intervention programs when working with children with ARFID in clinical practice.

Eligibility

Primary outcome measure(s)

• Behavioral Pediatric Feeding Scale — 12 weeks
  The Behavioral Pediatric Feeding Assessment Scale (BPFAS), was adapted into Turkish , and later studied with parents of children aged 3-12 years attending preschool and primary school. The original scale consists of 35 items, 25 of which relate to the child's feeding behavior and 10 to the caregiver responsible for feeding. However, the Turkish adaptation was conducted using only the 25 items related to the child. Among these, six items are positively worded (items 1, 3, 5, 6, 9, and 16), while the remaining 19 are negatively worded. Responses are scored on a five-point Likert scale ranging from 1 (never) to 5 (always), with positively worded items reverse-scored. Parents are asked whether each item represents a problem for them. A total score above 84 indicates the presence of a feeding disorder, while reporting more than nine problematic items reflects a high number of feeding-r
• Children's Eating Behavior Questionnaire — 12 weeks
  The Children's Eating Behaviour Questionnaire (CEBQ), is a parent-reported, Likert-type questionnaire designed to assess eating behaviors in children aged 2-9 years. It includes 35 items rated on a 5-point scale (1 = never, 5 = always) and encompasses eight subscales that reflect different aspects of children's eating behaviors. Reported Cronbach's alpha coefficients for the original scale range from 0.72 to 0.91, indicating good internal consistency. The validity and reliability of the CEBQ in Turkey were examined.The scale consists of eight subscales that can be grouped into two main dimensions.
• Sensory Eating Problems Scale — 12 weeks
  The Sensory Eating Problems Scale (SEPS) was developed for children aged 3-11 years to evaluate sensory-related feeding difficulties. The scale consists of 22 items rated on a 5-point Likert scale (0 = never, 1 = rarely, 2 = sometimes, 3 = often, 4 = always) and includes six subscales: Food Texture Aversion, Single Food Focus, Vomiting, Temperature Sensitivity, Expulsion, and Overstuffing. SEPS is completed by the child's caregiver. Confirmatory factor analysis by Seiverling et al. (2019) reported χ²/df = 2.63, CFI = 0.90, and RMSEA = 0.06, supporting the six-factor model as an acceptable structure for assessing sensory feeding problems. In addition, Cronbach's alpha values for the subscales were 0.85 for Food Texture Aversion, 0.70 for Single Food Focus, 0.73 for Vomiting, 0.72 for Temperature Sensitivity, 0.71 for Expulsion, and 0.71 for Overstuffing. The Turkish validity and reliability study was conducted by Demirok et al. in children aged 3-11 years.
• Sensory Profile — 12 weeks
  The Sensory Profile, developed by Dunn and colleagues, is used to assess sensory processing abilities in children aged 3-10 years. It consists of 125 items and evaluates three main domains: Sensory Processing (6 subdomains), Sensory Modulation (5 subdomains), and Behavioral and Emotional Responses (3 subdomains). The subdomains include Auditory Processing, Visual Processing, Vestibular Processing, Tactile Processing, Multisensory Processing, Oral Sensory Processing, Sensory Processing related to Endurance and Tone, Regulation of Movement and Body Position, Regulation of Activity Level by Movement, Modulation of Sensory Input Affecting Emotional Responses, Modulation of Visual Input Affecting Emotional Responses and Activity Level, Emotional/Social Responses, Behavioral Outcomes of Sensory Processing, and Items Indicating Thresholds of Responsiveness. The Turkish validity and reliability study of the scale was conducted by Kayıhan and colleagues.
• Goal Attainment Scale (GAS) — 12 weeks
  The Goal Attainment Scaling (GAS) is widely used in patient-centered treatment approaches with no age restrictions, and it is based on the principle of collaboratively setting treatment goals between the therapist and the patient. In this study, parents are asked during the initial assessment to define five individual goals they wish to achieve throughout the therapy process. Each goal is prioritized by the parent, who also rates the perceived level of difficulty. At the post-treatment evaluation, each goal is scored on a five-point scale ranging from -2 to +2 (-2 = much less than expected outcome, -1 = somewhat less than expected, 0 = expected outcome, +1 = somewhat more than expected, +2 = much more than expected). As a performance-based measure, GAS does not require separate validity and reliability testing for the Turkish context.
