We sought to develop and evaluate a composite memory score from the neuropsychological battery used in the Alzheimer’s Disease (AD) Neuroimaging Initiative (ADNI). We used modern psychometric approaches to analyze longitudinal Rey Auditory Verbal Learning Test (RAVLT, 2 versions), AD Assessment Schedule - Cognition (ADAS-Cog, 3 versions), Mini-Mental State(More)
The Alzheimer’s Disease Neuroimaging Initiative (ADNI) measures abilities broadly related to executive function (EF), including WAIS-R Digit Symbol Substitution, Digit Span Backwards, Trails A and B, Category Fluency, and Clock Drawing. This study investigates whether a composite executive function measure based on these multiple indicators has better(More)
The current study had two goals. The first goal was to test the mediational role of young adult personality in the relation between parental alcoholism and young adult alcoholism. The second was to examine the associations between personality and alcohol use motives and reasons to limit drinking in order to explore possible mechanisms by which personality(More)
Racial and ethnic disparities in mental health care access in the United States are well documented. Prior studies highlight the importance of individual and community factors such as health insurance coverage, language and cultural barriers, and socioeconomic differences, though these factors fail to explain the extent of measured disparities. A critical(More)
The objectives of this study were to evaluate the association between caregiver burden and preventive dental care use for children with special health care needs (CSHCN) and assess if caregiver burden explains the relationship between child- and family-level characteristics and preventive dental care use. Samples of US CSHCN ages 3-17 years with a(More)

OBJECTIVE Insufficient research has established the measurement properties of the Children with Special Health Care Needs (CSHCN) Screener. This leaves unclear whether CSHCN Screener-based estimates reliably identify CSHCN. We used classical and modern test theory to establish the CSHCN Screener's internal psychometric properties. METHODS Data came from(More)
BACKGROUND Cardiovascular disease is the leading cause of increased mortality for adolescents with advanced kidney disease. The quality of preventive cardiovascular care may impact long-term outcomes for these patients. METHODS We reviewed the records of 196 consecutive adolescents from eight centers with pre-dialysis chronic kidney disease, on dialysis(More)
BACKGROUND Multilevel models (MLM) offer complex survey data analysts a unique approach to understanding individual and contextual determinants of public health. However, little summarized guidance exists with regard to fitting MLM in complex survey data with design weights. Simulation work suggests that analysts should scale design weights using two(More)
