The sensory dimension of attention deficit hyperactivity disorder: a case–control study on the impact of sensory profile on daily functioning among Turkish children with ADHD

Abstract Background Sensory profile differences are commonly observed in children with Attention Deficit Hyperactivity Disorder (ADHD). This study aimed to examine the sensory profiles of children with ADHD, their impact on symptom severity, and their association with quality of life. Methods Forty-six children aged 8–10 diagnosed with ADHD and their parents (case group) and 38 age-matched controls without ADHD or other neurodevelopmental disorders (control group) participated. Psychiatric evaluations were conducted using the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children–Present and Lifetime Version (K-SADS-PL), and symptom severity was assessed using the Clinical Global Impression (CGI) Scale. Parents completed the Caregiver Sensory Profile Questionnaire, Conners’ Parent Rating Scale, and the Pediatric Quality of Life Inventory (PedsQL). Results The ADHD group had significantly higher CGI scores ( p < 0.001). PedsQL subdomains, all sensory processing measures, and sensory profile quadrant scores differed significantly between groups (all p < 0.001). CGI scores positively correlated with all sensory profile domains (all p < 0.01). The Conners’ total score correlated with all sensory processing domains and quadrants except auditory processing ( r = -0.198, p = 0.07). Sensory profile measures also showed significant correlations with physical and school functioning. Conclusions Tailored sensory-based interventions may play a critical role in reducing functional impairments in children with ADHD.
