The study aimed to develop the Homophobic Bullying Scale and to investigate its psychometric properties. The items of the Homophobic Bullying Scale were created to measure high school students' bullying behaviors motivated by homophobia, including verbal bullying, relational bullying, physical bullying, property bullying, sexual harassment, and…

Statistical biases associated with single-level analyses underscore the importance of partitioning variance/covariance matrices into individual and group levels. From a multilevel perspective based on data from 21,579 students in 58 high schools, the present study assesses the multilevel factor structure of motivation and engagement with a…

The purpose of this study is to test the validity of scores on the Homework Purpose Scale using 681 rural and 306 urban high school students. First, confirmatory factor analysis was conducted on the rural sample. The results reveal that the Homework Purpose Scale comprises three separate yet related factors, including Learning-Oriented Reasons,…

The aim of this study was to develop a scale assessing high school students' self-efficacy beliefs in chemistry-related tasks and to assess psychometric properties of scores on this scale. A pilot study with a sample of 150 high school students provided initial evidence for two-factor structure of 16-item scale, named High School Chemistry…

Motivation deficits are common in high school and constitute a significant problem for both students and teachers. The Academic Amotivation Inventory (AAI) was developed to measure the multidimensional nature of the academic amotivation construct (Legault, Green-Demers, & Pelletier, 2006). The present project further examined the consistency…

The purpose of this study is to test the validity of scores on the Homework Management Scale (HMS) using 681 rural and 306 urban high school students. Based on a randomized split of the rural sample, the author first conducts exploratory factor analysis on Group 1 (n = 341) and confirmatory factor analysis on Group 2 (n = 340). The results reveal…

The psychometric properties and multigroup measurement invariance of scores on the Self-Efficacy for Self-Regulated Learning Scale taken from Bandura's Children's Self-Efficacy Scale were assessed in a sample of 3,760 students from Grades 4 to 11. Latent means differences were also examined by gender and school level. Results reveal a…

Two aspects of the reliability of multidimensional measures can be distinguished: the amount of scale score variance that is accounted for by all underlying factors (composite reliability) and the degree to which the scale score reflects one particular factor (construct reliability). Confidence intervals for composite and construct reliabilities…

Analysis of the factor structure of rankings and ratings of three sets of values illustrates how counselors use them in working with adolescents. Data were analyzed from 600 interviews with eleventh graders. The analyses of gender-related differences give counselors perspectives from which to explore the values students consider important in…

Studied the higher order factor structure of a self-control test developed by H. Grasmick and others (1993). Results for 1,966 eighth and ninth graders show that the self-control test may provide more valid measurement of the constructs it was designed to measure than previous research suggested. (SLD)

The purpose of this study was to investigate the latent structure of the Learning and Study Strategies Inventory-High School (LASSI-HS) through confirmatory factor analysis and factorial invariance models. A simple modification of the three-factor structure was considered. Using a larger sample, cross-validation was completed and the equality of…
