Mentor Support Provisions Scale: Measure dimensionality, measurement invariance, and associations with adolescent school functioning.

Mentoring relationships can have important effects on adolescents' psychosocial and academic outcomes; however, the transactions within mentoring relationships that may account for impact on psychosocial and academic outcomes are not well understood. This study investigated the psychometric properties of the Mentor Support Provisions Scale (MSPS), a tool for assessing the types of support that mentors provide. Exploratory factor analyses and confirmatory factor analyses were used to determine measure dimensionality.

Effect of Trajectories of Friends' and Parents' School Involvement on Adolescents' Engagement and Achievement.

In a sample of 527 academically at-risk youth, we investigated trajectories of friends' and parents' school involvement across ages 12-14 and the joint contributions of these trajectories to adolescents' age 15 school engagement and academic achievement. Girls reported higher levels of friends' and parents' school involvement than boys. Both parents' and friends' school involvement declined across ages 12-14.

Effects of Extracurricular Participation During Middle School on Academic Motivation and Achievement at Grade 9.

We investigated the effect of participating in two domains of extracurricular activities (sports and performance arts/clubs) in Grades 7 and 8 on Grade 9 academic motivation and letter grades, above baseline performance. Participants were 483 students (55% male; 33% Euro-American, 25% African American, and 39% Latino). Propensity score weighting controlled for potential confounders in all analyses.

Effect of school belonging trajectories in grades 6-8 on achievement: Gender and ethnic differences.

This study investigated the association between trajectories of school belonging across grades 6-8 and academic achievement in grade 8 in an ethnically diverse sample of 527 academically at-risk adolescents. Students reported annually on school belonging. Reading and math achievement were assessed at grade 5 (baseline) and grade 8.

Latino Students' Transition to Middle School: Role of Bilingual Education and School Ethnic Context.

Participants were 204 academically at-risk Latino students recruited into a study when in first grade and followed for 9 years. Using piecewise latent growth curve analyses, we investigated trajectories of teacher-rated behavioral engagement and student-reported school belonging during elementary school and middle school and the association between trajectories and enrollment in bilingual education classes in elementary school and a change in school ethnic congruence across the transition to middle school. Overall, students experienced a drop in school belonging and behavioral engagement across the transition.

Learning-related skills and academic achievement in academically at-risk first graders.

Using an academically at-risk, ethnically diverse sample of 744 first-grade children, this study tested a multi-method (i.e., child performance measures, teacher ratings, and peer ratings) measurement model of learning-related skills (i.

Effect of retention in elementary grades on grade 9 motivation for educational attainment.

This study investigated the effect of grade retention in elementary school on students' motivation for educational attainment in grade 9. We equated retained and promoted students on 67 covariates assessed in grade 1 through propensity score weighting. Retained students (31.

Effect of peer nominations of teacher-student support at individual and classroom levels on social and academic outcomes.

This longitudinal study examined the prospective relations between 713 elementary students' individual peer teacher support reputation (PTSR) and a measure of the classroom-wide dispersion of peer nominations of teacher support (Centralization of Teacher Support) on students' peer relatedness (i.e., peer acceptance and peer academic reputation) and academic motivation (i.

Assessment of adolescents' motivation for educational attainment.

The Adolescent Motivation for Educational Attainment Questionnaire is a 32-item questionnaire (we drew 20 items from 3 subscales of the Educational Motivation Questionnaire; Murdock, 1999) that was developed to measure multiple potential dimensions of adolescents' motivation to complete high school and enroll in post-secondary education, including competence and effort beliefs; perceived value of education; and peer, teacher, and parent support for educational attainment. We assessed a multiethnic sample (N = 569) of low-achieving students who started 1st grade together in 1 urban and 2 small city school districts. Participants were assessed over 2 consecutive years (Grades 8 and 9 given prior grade retention, or Grades 9 and 10 if not retained).

Effect of retention in elementary grades on transition to middle school.

The authors investigated the effects of retention in grades 1 to 5 on students' reading and math achievement, teacher-rated engagement, and student-reported school belonging in middle school. From a multiethnic sample (N=784) of children who scored below the median on a test of literacy in grade 1, an average of 75 students subsequently retained in grades 1 to 5 were matched with an average of 299 continuously promoted students on the basis of propensity to be retained in the elementary grades. A total of 20 imputed datasets were analyzed, all of which showed good balance across the 67 baseline covariates used to calculate propensity scores.
