Background Atypical visual behaviors are highly prevalent in children with autism spectrum disorder (ASD), yet validated instruments to quantify these symptoms remain limited. This study aimed to develop and validate the Visual Behavior Questionnaire (VBQ) for the assessment of visual symptoms associated with ASD. Methods Parents of 93 children with clinically confirmed ASD (aged 4–12 years) and 100 typically developing controls completed a 15-item pilot Visual Behavior Questionnaire. The questionnaire was refined and psychometrically evaluated using Rasch analysis. Discriminative ability, validity, and test–retest reliability were subsequently assessed. Results Rasch refinement yielded an 8-item instrument with ordered response categories, satisfactory model fit, and no gender-based DIF. Person reliability was 0.83 and item reliability 0.93, supporting adequate discrimination and stable item hierarchy. Unidimensionality was supported by residual principal component analysis. Targeting revealed a floor effect (−1.68 logits), reflecting limited representation of high symptom severity. ROC analysis showed excellent discrimination between the ASD and control groups within this sample (AUC = 0.951), with a preliminary optimal cutoff score of ≥ 7. The VBQ correlated significantly with MEM and NPC values and showed excellent repeatability (ICC = 0.980). Conclusion The VBQ demonstrates strong psychometric performance and provides a brief tool for identifying visual symptoms associated with ASD. External validation, including longitudinal studies, is needed before its utility for monitoring and clinical management can be established.
