Abstract

Objective:The prevalence of autism spectrum disorder (ASD) has increased 10-fold in the past 40 years, and disparities have been noted by race/ethnicity and socioeconomic status, prompting concern about diagnostic accuracy. Provider perceptions of ASD diagnostic accuracy are not known. We conducted a survey of providers who diagnose ASD assessing how nonclinical factors might affect ASD diagnostic rates.Methods:The mixed-mode survey was sent to the members of the Society of Developmental and Behavioral Pediatrics with clinical interest in ASD (n = 400). Respondents used a Likert-type scale to address how often they and their colleagues overdiagnosed or underdiagnosed ASD. They were also asked how families grouped by race/ethnicity, education, socioeconomic status, and urbanicity perceived an ASD diagnosis.Results:Sixty-three percent of providers completed the survey. Eight point seven percent of providers self-reported that they overdiagnose ASD at least sometimes. However, 58% of providers reported that local colleagues overdiagnose ASD at least sometimes. Seven point eight percent of providers self-reported underdiagnosing ASD at least sometimes and cited parents not wanting a diagnosis as one of the most common reasons they may underdiagnose. Providers reported that non-white and rural families were more likely to think that ASD diagnosis was "a bad thing"than "a good thing"than white and urban and suburban families, respectively.Conclusion:Providers report moderate rates of ASD misdiagnosis and perceive differences in diagnostic preferences according to family characteristics. The study results may help explain the trends and disparities in ASD diagnosis.
