National Norms and Percentiles for the Pediatric Emotional Distress Scale.

We estimated norms and percentiles for the Pediatric Emotional Distress Scale (PEDS) in order to enhance its utility as a screening tool for emotional and behavioral distress following a major. The PEDS was administered to a nationally representative sample of parents of children ages 5-12 from all 50 states (N = 1,570). Approximately 15% of the parents reported a trauma/stress in the past 12 months. Results showed good internal consistency (α = .92) and concurrent validity, with significantly higher scores for the trauma/stress subsample compared to the no trauma/stress subsample. PEDS scores were also significantly higher in younger children (age 5-6) compared to older children (7-12), pointing to the need for separate clinical cut-off scores for younger versus older children. Finally, we examined the factor structure of the PEDS with results supporting a four factor solution in the trauma/stress subsample. For screening purposes, we recommend cut-off scores of 39 (ages 5-6) and 35 (ages 7-12) which correspond to the 90th percentile.

Deficits in Parent Knowledge of Behavior Management Skills is Strongly Associated with CD Symptoms but Not ODD Symptoms.

We conducted secondary analyses of existing data to examine the association between parent scores on the Knowledge of Effective Parenting Test (KEPT) and child symptoms of Conduct Disorder (CD) and Oppositional Defiant Disorder (ODD). Parent knowledge of behavior management skills and child behavior symptoms were assessed in a nationally representative sample of parents/guardians (N = 1,570) of children aged 5-12 from all 50 states. Results showed consistent and robust correlations between parent knowledge of behavior management skills and CD symptoms but not ODD symptoms. These findings suggest that parent knowledge of behavior management may be a greater risk factor for CD than ODD, with implications for taxonomy and understanding the etiology of these two disorders. We also discuss the implications of these findings for the prevention and treatment of these two disorders which are often grouped together in treatment trials.

National Norms for the Vanderbilt ADHD Diagnostic Parent Rating Scale in Children.

OBJECTIVE: To provide national norms and percentiles for both research and clinical scoring modalities of the Vanderbilt Attention Deficit/Hyperactivity Disorder (ADHD) Diagnostic Parent Rating Scale (VADPRS) for a representative sample of children ages 5-12 in the United States. METHOD: The five clinical subscales of the VADPRS were completed by 1,570 caregivers of children ages 5-12 in the United States, with children representative of the national population on key demographic variables including race, sex, ethnicity, family income, and family educational level. Descriptive statistics and measures of internal consistency of both dimensional and symptom count scoring were provided for each of the five clinical subscales of the inventory, as well as percentiles and group comparisons for select dimensional scoring subscales based on age and child sex. RESULTS: Measures of internal consistency for each subscale using both scoring modalities of the VADPRS ranged from high to acceptable. There were statistically significant differences among the different subscales for both age (ADHD hyperactivity, anxiety/depression) and sex [both presentations of ADHD, oppositional defiant disorder (ODD)] for the total sample. These differences, however, were modest in magnitude and unlikely to be clinically meaningful. CONCLUSIONS: This study enhances the research and clinical utility of the VADPRS by providing national norms and percentiles for each of its subscales. Differences between age and sex across the sample were statistically significant for two of the subscales (Hyperactivity and Anxiety/Depression) with additional subscales significant for sex alone (Inattentive and ODD), but these differences were not substantial enough to indicate a need for separate cut-offs for screening purposes.
