Background/Objectives: Avoidant/Restrictive Food Intake Disorder (ARFID) frequently co-occurs with Autism Spectrum Disorder (ASD), yet its detection and assessment remain challenging. This study aimed to analyze terminology and professionals&rsquo: views on features and indicators related to ARFID among Spanish professionals working with autistic individuals, identifying potential gaps and training needs. Methods: A cross-sectional study was conducted with 194 professionals (62 speech therapists, 62 psychologists, and 70 occupational therapists) from different regions of Spain, who completed a 13-item questionnaire on their familiarity with terminology, definitions, and features they consider indicative to ARFID. Descriptive analyses and chi-square tests were applied to explore interprofessional differences. Results: Significant differences emerged across disciplines (p <: 0.001). Psychologists showed greater familiarity with DSM-5 diagnostic criteria (78%), while speech-language therapists (72%) and occupational therapists (69%) more frequently endorsed sensory, oromotor, and behavioral features as relevant. Across all groups, 61% reported uncertainty about ARFID diagnostic criteria, and only 34% reported familiarity with validated assessment tools. Conclusions: Spanish professionals working with ASD populations demonstrate heterogeneous and generally limited understanding of the features they associate with ARFID, with discipline-specific approaches to assessment. These findings provide initial evidence in Spanish-speaking contexts and underscore the need for structured training and validated Spanish-adapted instruments to support early and accurate ARFID identification.
