1. Background Approximately 80% of children with developmental disabilities have feeding problems (Field, Garland, & Williams, 2003) In comparison to typically developing peers, children with ASD have significantly greater feeding problems and eat a narrower range of food (Kozlowski, Matson, Belva, & Rieske, 2012; Schreck, Williams, & Smith, 2004) Approximately 60-90% of children with ASD exhibit feeding difficulties, such as food selectivity, food refusal, and resistance to trying new foods (Bruns & Thompson, 2011; Kerwin, Eicher, & Gelsinger, 2005) Well researched and effective interventions for children with ASD and mealtime challenges include escape extinction, reinforcement, prompting, stimulus fading, and combining or sequencing new foods with a familiar food (Volkert & Piazza, 2012) There is limited research to support interventions related to food characteristics, communication, and the physical environment Currently, there is no study that combines multiple techniques across various domains into one intervention package Purpose To determine the efficacy and social validity of a multicomponent intervention package designed to improve the acceptance of less preferred foods and/or food groups by young children with Autism Spectrum Disorder (ASD). Results Data will be collected for up to 3 behaviorally defined responses for each participant Data will be analyzed using visual data analysis strategies such as examining graphed data for level and trend Results of intervention cannot be determined as of date due to ongoing data collection Baseline data indicate that, in general: Parents are consistently not offering less-preferred foods When presented with less-preferred foods, children are not accepting the food Challenging behaviors, such as leaving the table, may be influenced by parent or sibling presence or behaviors Interobserver agreement (IOA) is 80%-100% during baseline Procedural fidelity is 100% during baseline References Provides a comprehensive view of feeding difficulties Recognizes the complexity of mealtime challenges Provides possible intervention strategies that occupational therapists can use for children with mealtime challenges Promotes occupation-based and family-centered practices Encourages occupational therapists to work in the area of mealtime challenges Fosters research in single subject research design to encourage rigorous, individualized treatment plans Bruns, D.

Review: previous evaluations, medical history, and confirm ASD diagnosis 2. Assessment: child’s performance, parent’s interactions, child’s preferences, and interview parent about mealtimes 3. Baseline Data Collection: collect data on behaviorally defined responses for parent and child during regular meals or snack sessions 4. Planning: develop individualized interventions with parent and child addressing- Food characteristics: altering target foods such as the texture or color of food, etc. Communication supports: supporting the child’s expressive and/or receptive communication such as visual supports, menus, etc. Physical environment: changing the environment in which the meals take place such as location, seating, distractors, etc. Social environment: modifying the parent/child interactions such as use of praise, prompting strategies, etc. 5. Intervention: Coaching: parent implements intervention with researcher supervision and coaching including prompting, modeling, and other support as necessary Independent: parent implements intervention without any coaching (parents transition to this phase when they have reached 80% or greater independence with implementation of intervention strategies) 6. Follow-up: reassessment and maintenance (1 time per month for 1-3 months) (Note: Interobserver agreement and procedural fidelity will be collected throughout all phases of the study) Implications for Occupational Therapy Conclusions Procedures This study addressed multiple dimensions of mealtime for children with ASD and their families. Results from initial baseline data is consistent with previous studies indicating that children with ASD eat a limited variety of foods, exhibit challenging behaviors during mealtime, or refuse to try new foods. These difficulties are important to address because they may lead to child nutritional problems and increase family stress. Prospectively, these individualized intervention packages will improve children’s mealtime behaviors. It is predicted that parents will find the intervention acceptable. Additionally, it is anticipated that parents’ prior knowledge of strategies will increase intervention acceptability and procedural fidelity. Research Design Single-subject research design (multiple baseline across participants with generalization probes) AACPDM Level of Evidence II Pre- and post-intervention assessments Participants Blake is a 6 year old boy whose food repertoire consists of 34 foods, not including snacks and desserts. Blake’s challenging mealtime behaviors include leaving the table and minimal use of utensils. Blake often times takes longer than 20 minutes to finish a meal and tantrums when presented with less-preferred foods. Craig is a 9 year old boy whose food repertoire consists of 10 foods, not including snacks and desserts. Craig’s challenging mealtime behaviors include licking food, regurgitating food, and leaving the table. Stephen is a 5 year old boy whose food repertoire consists of 22 foods, not including snacks and desserts. Stephen’s main challenging mealtime behavior is playing with food, leaving the table, and refusing to taste unfamiliar foods. When presented with less-preferred foods, Stephen cries, whines, or protests. Dominic is an 8 year old boy whose food repertoire consists of 8 foods, not including snacks or desserts. Dominic’s challenging mealtime behaviors include leaving the table, taking longer than 20 minutes to finish a meal, and overstuffing his mouth. When presented with less-preferred foods, Dominic tantrums, cries, or protests.
