IntroductionThe diagnosis and care of children and adolescents with neurodevelopmental disorders presents a public health crisis in China. Attention deficit hyperactivity disorder (ADHD) is one of the most frequent conditions. Many Chinese children and adolescents with ADHD are underdiagnosed and undertreated. This study aimed to evaluate the awareness and attitude parents have about ADHD, and investigated potential factors influencing ADHD medical visit status among school-aged children in Shanghai.MethodsA random cluster sampling method was used, and four primary schools in Shanghai were selected. One class was randomly selected from each grade, including students and their parents. Parents completed the Swanson, Nolan, and Pelham Version IV Questionnaire (SNAP-IV) parent form and questionnaire concerning ADHD awareness, knowledge, attitude and status of ADHD medical visit. Descriptive analysis was conducted on the overall results and logistic regression analysis was performed to explore the influencing factors of ADHD medical visit.ResultsWe received 617 valid questionnaires. There were 313 boys (50.7%) and 304 girls (49.2%), with a median age of 8 years old (p25 = 7, p75 = 9). 42.4% parents believed they had some knowledge about ADHD, and 73.5% of them thought ADHD was a neurologically based disorder or neurological condition by nature. Parental ADHD information came from the following sources: Internet/TV (n = 458, 74.2%), families/friends (n = 267, 43.2%), print publication (n = 208, 33.7%), psychiatrists/pediatricians (n = 192, 31.1%), schools/teachers (n = 186, 30.1%) and other ADHD patients (n = 48, 7.7%). When children had ADHD-like behaviors, most parents (61.5%) educated children to behave themselves, 59.1% parents tried to get help from psychiatrists/pediatricians, 55.5% of them would ask psychologist for help. In terms of the ADHD prevalence, the SNAP-IV positive screen rate was 4.3% (n = 27). Only 33.3% (9/27) of parents went to the hospital for consultation and treatment. Multivariate logistic regression model showed that parental knowledge about ADHD (OR = 13.67, 95%CI: 1.72, 144.39, P = 0.01) was significantly correlated with the medical visit. Parents with sufficient knowledge of ADHD tend to visit hospital for help when they thought their children had ADHD related symptoms.ConclusionsThe majority of parents accepted ADHD as a neurodevelopmental disorder by nature, but some parents still had certain misunderstandings about ADHD. The main source of information for parents to obtain information about ADHD was through the TV/Internet. Parents’ perceptions and knowledge were key to whether children received appropriate treatment for their ADHD. However, medical visits to address ADHD among school-aged children were still lower than expected. Government and healthcare institutes should work to improve ADHD public awareness and to help patients and their families gain access to mental health resources.
