BACKGROUND: Previous research has reported lower treatment rates for externalizing disorders among non-Western children as compared to Western children. Ethnic differences in parental detection may be an explanation for this discrepancy. AIMS: In a cross-sectional study among the four largest ethnic groups in the Netherlands, namely Dutch, Moroccan, Turkish and Surinamese, we examined the influence of ethnicity on parental detection of behavioural disorders. METHOD: A total of 270 children (aged 6-10 years) and their parents were interviewed regarding psychiatric disorders and socio-demographic data. Sensitivity and specificity were calculated by using standard definitions, with adjustment for parental educational level. RESULTS: Sensitivity to detect any externalizing disorder and ADHD in particular was significantly lower among Moroccan and Surinamese parents when compared to Dutch parents. Sensitivity to detect ADHD tended to be lower among Turkish parents. Specificity to detect any externalizing disorder was higher among Moroccan and Turkish parents. Specificity to detect ADHD was higher among Moroccan parents and tended to be higher among Turkish parents. CONCLUSIONS: The detection rate of externalizing disorders is markedly lower among non-Dutch parents than among Dutch parents. This finding emphasizes the importance of taking parents' cultural context into account when appraising their report on possible externalizing disorders in their children.
To assess the validity of ADHD in children with mental retardation, we applied Robins and Guze's [Robins, E., and Guze, S.B. (1970). Establishment of diagnostic validity in psychiatric illness: Its application to schizophrenia. American Journal of Psychiatry, 126, 983-987.] criteria for determining the validity of a psychiatric disorder. We review the literature describing clinical correlates, family history, treatment response, laboratory studies, course, and outcome of children with ADHD and mental retardation. Although clearly an area in need of further research, there is preliminary evidence to suggest that ADHD is a valid psychiatric condition in children with mental retardation. Nevertheless, without knowing the base rates of ADHD symptoms in the mental retardation population, the positive predictive power and negative predictive power of ADHD symptoms in this population remain an open question. In addition to assessment of base rate symptoms, future research should consider what diagnostic algorithm may best be applied to the diagnosis of ADHD in mental retardation.
BACKGROUND: In most cases of Fetal Alcohol Spectrum Disorder (FASD), the pathognomonic facial features are absent making diagnosis challenging, if not impossible, particularly when no history of maternal drinking is available. Also because FASD is often comorbid with Attention Deficit Hyperactivity Disorder (ADHD), children with FASD are frequently improperly diagnosed and receive the wrong treatment. Since access to psychological testing is typically limited or non-existent in remote areas, other diagnostic methods are needed to provide necessary interventions. OBJECTIVES: To determine if a characteristic behavioural phenotype distinguishes children with FASD from typically developing children and children with ADHD and use this information to create a screening tool for FASD diagnosis. METHODS: Parents and caregivers completed the Child Behavior Checklist (CBCL), a well-established standardized tool for evaluating children's behavioural problems. Results from 30 children with Fetal Alcohol Syndrome or Alcohol-Related Neurodevelopmental Disability, 30 children with ADHD, and 30 typically developing healthy children matched for age and socioeconomic status with FASD were analyzed. Based on our previous work, 12 CBCL items that significantly differentiated FASD and control groups were selected for further analyses. Stepwise discriminant function analysis identified behavioural characteristics most strongly differentiating groups and Receiver Operating Characteristics (ROC) curve analyses determined sensitivity and specificity of different item combinations. RESULTS: Seven items reflecting hyperactivity, inattention, lying and cheating, lack of guilt, and disobedience significantly differentiated children with FASD from controls. ROC analyses showed scores of 6 or higher on these items differentiated groups with a sensitivity of 86%, specificity of 82%. For FASD and ADHD, two combinations of items significantly differentiated groups with high sensitivity and specificity (i) no guilt, cruelty, and acts young (sensitivity = 70%; specificity = 80% (ii) acts young, cruelty, no guilt, lying or cheating, steals from home, and steals outside (sensitivity = 81%; specificity = 72%). These items were used to construct a potential FASD screening tool. CONCLUSIONS: Our findings identifying the behavioural characteristics differentiating children with FASD from typically developing children or children with ADHD have the potential for development of an empirically derived tool for FASD tool to be used in remote areas where psychological services are not readily available. This technique may speed up diagnosis and intervention for children without ready access to formal assessments.
