School climate is increasingly recognized by scholars and policymakers as a crucial factor associated with students' educational experiences. Hence, practitioners endeavor to equitably measure and improve school climate to promote favorable student academic and behavior outcomes. Unfortunately, school climate research is fragmented, and a…

By the end of the kindergarten, students are expected to possess early academic skills as well as the social maturity to be successful in first grade. Students leaving kindergarten without these readiness skills are sometimes held back in first grade or referred for a special education evaluation in later grades if they fail to make adequate…

We examined internal consistency and test-retest reliability of a measure of dispositional optimism, the Life Orientation Test-Revised, in 121 opiate-dependent patients seeking methadone treatment. Internal consistency was adequate at baseline (alpha = 0.69) and follow-up (alpha = 0.72). Low socioeconomic status and being on disability were…

This study examined the gender-related differential predictive validity of five subscales of the Institutional Integration Scale (IIS) with regard to college student withdrawal. Differential functioning of the IIS across genders was assessed using an item response theory (IRT)-based framework of differential item and test functioning. The results…

This study investigates community-level prediction of adolescent substance use and problem behaviors using ratings by community leaders to assess the effects of four risk factors on levels of drug use and problem behaviors. Three questions are examined: (a) Can psychometrically sound measures of community leader perceptions of risk factors in…

The objective of this study was to develop a screen assessing domains in at-risk and substance-using adolescents. The Adolescent Domain Screening Inventory (ADSI) consists of four subscales: school, family, community, and individual or peer. A convenience sample of 6,661 youths was employed. Analyses included concurrent criterion validity, known…

A study involving the construction and administration of Black and White intelligence test forms to 386 Blacks and 386 Whites indicated that Blacks did not perform significantly better on the Black test form, suggesting differences in Black special education placement rates are not affected by underrepresentation in the test development group.…

This study investigated the differential validity of the Wide Range Intelligence Test, which is a new, brief measure of ability. Participants (N = 744) ranged in age from 5 through 85 years (M = 26.7 years, SD = 21.4 years) and varied by the demographic variables of gender, race/ethnicity (Anglo, African American, Hispanic), and education level…

This study was undertaken to shed light on problems concerning the construction and use of a common test battery for various South African population groups. Specifically, the psychometric suitability for use with Indian and Black pupils, of the Junior Aptitude Tests (JAT), which were standardized for White pupils in Standard 7 was studied. The…

School readiness assessment is a prominent feature of early childhood education. Because the construct of readiness is multifaceted, we examined children's patterns on multiple indicators previously found to be both theoretically and empirically linked to school readiness: social skill, interactions with parents, problem behavior, and performance…
