evaluating the validity of sleep disturbance scale for children in attention-deficit/hyperactivity disorder

Introduction: attention-deficit/hyperactivity disorder (adhd) is prevalent in children and strongly associated with sleep disorders, emphasizing the clinical importance of diagnosing sleep disorders in these patients. here, we aimed to assess the validity of the sleep disturbance scale for children (sdsc) in children with adhd.methods: this cross-sectional study, conducted between 2020 and 2021, involved 204 children diagnosed with adhd and 202 healthy children as controls. participants were recruited using convenience sampling from schools, community centers, and pediatric clinics. demographic data were collected for all participants, and their parents completed the sdsc. the results of the two groups were analyzed and compared using the factor analysis method to examine question-answering patterns and item discrimination for adhd disorder.results: the mean total sdsc score was significantly higher in adhd patients than in controls (68.1±20.4 vs 57.3±18.2; p<0.05). adhd cases also exhibited significantly higher scores in disorders of initiating and maintaining sleep (dims) (21.6±7.5 vs 18.1±26.9; p<0.001), sleep disorder of breathing (sdb) (5.5±3.5 vs 4.9±2.5; p=0.006), the disorder of arousal (da) (5.9±4.0 vs 4.4±2.7; p<0.001), sleep-wake transition disorders (swtds) (17.8±6.6 vs 14.6±6.2; p<0.001), and sleep hyperhidrosis (shy) (4.5±3.5 vs 3.6±3.1; p=0.013) subscales. however, the area under the curve of all subscales was unsatisfactory (ranging from 0.54 to 0.63).conclusion: adhd patients displayed notably higher sdsc scores, particularly in the disorders of initiating and maintaining sleep, which exhibited the highest sensitivity. these findings emphasize the clinical relevance of using sdsc for diagnosing and addressing sleep disorders in individuals with adhd.
