Periodically, Maryland's sixth, eighth, tenth, and twelfth graders are surveyed to determine the nature, extent, and trend of alcohol, tobacco, and other drug (ATOD) use among adolescents. The "2007 Maryland Adolescent Survey (MAS)" presents the latest findings regarding ATOD use by Maryland's adolescents and compares State and local…

This study investigated changes in intellectual orientations of 4,124 California high school students who completed the Omnibus Personality Inventory. The three dependent measures of intellectual orientations were Autonomy (which measures independence of thought and judgment), Theoretical Orientation (which reflects an interest in science,…

This study probed whether or not a distinctive Down syndrome (DS) pattern could be found in the realm of vocabulary comprehension. Groups of 29 each of DS adolescents, non-DS mentally retarded (MR) adolescents, and nonretarded children were statistically matched on receptive vocabulary ability; DS and MR groups were also matched for chronological…

A component analytic method for analyzing multivariate longitudinal data is presented that does not make strong assumptions about the structure of the data. Central to the method are the facts that components are derived as linear composites of the observed or manifest variables and that the components must provide an adequate representation of…

Kohn's work on the relationship between social class and parental values was expanded by searching for value dimensions other than Kohn's self-direction/conformity construct and by investigating three aspects of social structure: immigrant status, quality of neighborhood, and housing type. Data were collected from parents of 305 9- to 11-year-old…

The relationship of multiple linear regression to various multivariate statistical techniques is discussed. The importance of the standardized partial regression coefficient (beta weight) in multiple linear regression as it is applied in path, factor, LISREL, and discriminant analyses is emphasized. The multivariate methods discussed in this paper…

Examination of whether annual book budgets have kept pace with demands compares academic library book budgets in Germany and the United States in the mid-20th century with budgets of earlier years, taking into account annual book and serial production; costs of books; and the number of courses, faculty, and students. (Author/CLB)

The many methodological contributions of Raymond B. Cattell to multivariate analysis are discussed in terms of contemporary issues in structural equation modeling. His factor analytic approach is compared with current modeling practices. A critical evaluation finds much of Cattell's work still innovative, technically advanced, and valuable to…

This study was designed to explore relations among reading skills, metareading, memory, and metamemory. Interactions among these skills were investigated as related to reading ability, operativity, and grade level. The effects of experience, operativity, and metacognition on reading and memory skills were discussed. (Author/DWH)

Examined patterns of racial identity expression for 174 black adolescent females and 111 black adolescent males. Results from the Black Racial Identity Attitude Scale reveal that black adolescents widely endorse internalization attitudes that represent a healthy, self-defined racial transcendence. Females endorsed less preencounter attitudes…

Summarizes comparisons of self-reported interest by gender and experimental condition for middle school students (n=101) who performed scientific experiments under conditions designed to vary across difficulty levels, social contexts, and scenarios of fantasy to realism. Findings indicate that boys were more attentive to aspects of experimental…

Type I error rates for Yao's, James' first-order and second-order, and Johansen's tests of equality of mean vectors for two independent samples were estimated for various conditions defined by the degree of heteroscedasticity and nonnormality. Each procedure can be seriously nonrobust with exponential and log-normal distributions. (TJH)

The purpose of this study is to provide a microanalysis of differences in adaptive functioning seen between well-matched groups of school-aged children with autism and those diagnosed as having Pervasive Developmental Disorder-Not Otherwise Specified, all of whom functioned in the mild to moderate range of intellectual impairment. Findings…

The Basic Interest Scales (BISs) of the Strong Interest Inventory (SII; Harmon, Hansen, Borgen, & Hammer, 1994) have a 35-year history. The BISs are the specific content scales of the SII, as opposed to the SII general content scales, the General Occupational Themes (GOTs), which measure the six Holland (1997) RIASEC themes. Using 17,074…

This study examines tracking--the practice of grouping students into separate classes or courses based on their prior academic achievement--at the middle-school level, and the percentage of high-achieving students in tracked and untracked schools. It focuses on Massachusetts, a leader in "reforming" tracking, and the changes that have…
