This study describes the rate that Medicaid encounter data on gender, race/ethnicity, and diagnosis matched information in the medical record, among a statewide sample of Medicaid children who received ongoing care for attention deficit hyperactivity disorder (ADHD), conduct disorder (CD), and major depression (MD) in outpatient specialty mental health clinics in 1998-1999. The match rate for gender was 99%; and for race/ethnicity it was 71.8%, 90.5%, and 89.7% for Caucasian, African American, and Hispanic children, respectively. Misidentified Caucasian children were more likely to be recorded as African American or Hispanic than misidentified minority children to be recorded as Caucasian. Diagnosis match rates were high (ADHD: 98%, CD: 89%, MD: 89%). If the California Department of Mental Health relied solely on Medicaid encounter data, misclassification of African American or Hispanic children as Caucasian could produce an underestimate of their service use.
本研究描述了1998 - 1999年在全州范围内接受门诊专科心理健康诊所持续治疗的注意力缺陷多动障碍（ADHD）、品行障碍（CD）和重度抑郁症（MD）的医疗补助儿童样本中，医疗补助就诊数据在性别、种族/族裔和诊断方面与病历信息的匹配率。性别的匹配率为99%；种族/族裔方面，白人、非裔美国人和西班牙裔儿童的匹配率分别为71.8%、90.5%和89.7%。被误认的白人儿童被记录为非裔美国人或西班牙裔的可能性，高于被误认的少数族裔儿童被记录为白人的可能性。诊断匹配率较高（ADHD：98%，CD：89%，MD：89%）。如果加利福尼亚州心理健康部仅依赖医疗补助就诊数据，将非裔美国儿童或西班牙裔儿童误分类为白人可能会低估他们的服务使用情况。
