This study examined the reliability and validity evidence drawn from the scores of the Spanish version of the Achievement Goal Tendencies Questionnaire (AGTQ) using a sample of 2,022 (51.1% boys) Spanish students from grades 7 to 10. Confirmatory factor analysis replicated the correlated three-factor structure of the AGTQ in this sample: Learning…

Few studies have considered whether psychological determinants of nonsmoking among college students vary by ethnicity. The authors tested the theory of planned behavior (TPB) to explain differences in nonsmoking intentions of 238 African American and 197 Caucasian college students who completed an in-class TPB questionnaire and a smoking…

Data from a randomized clinical trial comparing the relative efficacy of individual cognitive-behavioral therapy (ICBT), family CBT (FCBT), and a family-based education/support/attention control (FESA) condition were used to examine associations between in-session therapeutic techniques related to parent training (PT) and treatment outcomes. This…

The authors examined the effects of remedial mathematics on performance in university-level economics courses using a natural experiment. They studied exam results prior and subsequent to the implementation of a remedial mathematics course that was compulsory for a subset of students and unavailable for the others, controlling for background…

The overuse of Massively Multiplayer Online Role Playing Games (MMORPGs) is becoming a significant problem worldwide, especially among college students. Similar to Internet addiction, the pathological use of MMORPG is a kind of modern addiction that can affect students' lives on both a physical and a psychological level. The purpose of this study…

This study analyzed gender differences in self-regulated learning components, motivational beliefs and achievement in self-regulated online learning environment. Sample of the study consisted of 145 participants from an online programming course which is based on synchronous and asynchronous communication methods over the Internet. Motivated…

The educational aspirations of Black males in urban, suburban, and rural high schools were examined in this study, using a nationally-representative sample of respondents to the National Educational Longitudinal Study (NELS:88/00). Hierarchical linear regression analysis revealed statistically significant relationships between aspirations and SES,…

When under conditions of high demand and allostatic load, are happiness and satisfaction in four domains (family, friends, academics, recreation) influenced more by external or internal factors? Do student-athletes who lead exceedingly complicated lives report happiness as a function of athletic achievement or internal disposition? Stanford…

This longitudinal study (2001-2005) considers the impact of a freshman orientation course on the persistence of black and white students at a mid-southern university, as well its relationship with college achievement (GPA). Controlling for gender, race, high school GPA, and decided on major, logistic regression was used to assess persistence;…

Purpose: The purpose of this paper is to examine first the job responsibilities undertaken by vice-principals and second to investigate the respective contribution of each job responsibility in preparing them for the principalship. Because new principals are drawn predominantly from the ranks of vice-principals in Hong Kong, it is important to…

Well-known numerical integration methods are applied to item response theory (IRT) with special emphasis on the estimation of the latent regression model of NAEP [National Assessment of Educational Progress]. An argument is made that the Gauss-Hermite rule enhanced with Cholesky decomposition and normal approximation of the response likelihood is…

As women have entered the work force and occupational sex segregation has declined, workers experience increased contact with the opposite sex on the job. The sex mix a worker encounters on the job should affect the cost of search for alternative mates and therefore the probability of divorce. This paper uses 1990 Census data to calculate the sex…

Regression models used in the analysis of interrupted time-series designs assume statistically independent errors. Four methods of evaluating this assumption are the Durbin-Watson (D-W), Huitema-McKean (H-M), Box-Pierce (B-P), and Ljung-Box (L-B) tests. These tests were compared with respect to Type I error and power under a wide variety of error…

Inoculation messages employed in past studies have been consistently preventative. Yet, if inoculation strategies are to be used in mass media campaigns, researchers need to know what the effects will be on all audience members--not just those known to support a message sponsor's position. A 3-phase experiment was conducted involving 558…

This article applies growth curve models to longitudinal count data characterized by an excess of zero counts. We discuss a zero-inflated Poisson regression model for longitudinal data in which the impact of covariates on the initial counts and the rate of change in counts over time is the focus of inference. Basic growth curve models using a…
