This study examines the risk for alcohol and other drug (AOD) problems resulting from alcohol plus marijuana use compared to alcohol-only use. Data are from telephone interviews with 1113 randomly selected college students attending two large urban universities in the southwestern United States. Alcohol and marijuana users (dual users) were more…

Using cluster analysis to combine specific adaptive measures related to mastery motivation (intrinsic motivation, self-adequacy, and locus of control), a total of 654 high school students were placed into distinct adaptive motivation groups. Mean scores on a variety of self-reported and peer-reported measures of interpersonal, intrapersonal, and…

This study describes the career exploratory behaviors of high school and college students and offers a typology of users of a Web-delivered computer career guidance application. Access to the records of 87,293 high school and college students allowed for the identification and replication of three emergent types of users: a general browser, a…

The purpose of this study was to assess the level of parental satisfaction with services of a child development center and to evaluate the physician-parent dimensions of communication. A total of 90 parents to children with disability ranging in age from 6 months to 6 years participated in the study (84% response rate). Attitudes regarding…

Cudeck and Browne (1983) proposed using cross-validation as a model selection technique in structural equation modeling. The purpose of this study is to examine the performance of eight cross-validation indices under conditions not yet examined in the relevant literature, such as nonnormality and cross-validation design. The performance of each…

National Longitudinal Survey of Youth and census data are used to examine the effect of both individual- and contextual-level determinants on Latinas' transition to first marriage (n = 745). Hypotheses derived from 4 leading theories of marriage timing are evaluated. Discrete-time event-history models that control for clustering within Labor…

This study examined kindergarten, first-grade, and second-grade teachers' intended and reported classroom use, as well as perceptions and knowledge of reading strategies and methods, before and after their participation in a 120-hour professional development workshop. A cluster analysis was conducted on the teachers' (N = 33) responses to a…

Individuals with autistic spectrum disorders (ASDs) often experience, describe and exhibit unusual patterns of sensation and attention. These anomalies have been hypothesized to result from overarousal and consequent overfocused attention. Parents of individuals with ASD rated items in three domains, "sensory overreactivity",…

This study recognizes that the teaching methodology is crucial and attempts to investigate the effect two…

The purpose of the study was to determine the typical teaching methods used in upper secondary physics in Finland and Norway and how students would like to study physics. Moreover, the further aim of seeing how certain background variables may explain students' desire to study their chosen specialist subject, physics or social science…

Valid measurement of physical activity is important for studying the risks for morbidity and mortality. The purpose of this study was to examine evidence of construct validity of two similar single-response items assessing physical activity via self-report. Both items are based on the stages of change model. The sample was 687 participants (men =…
