Social systems, particularly family, school, and peer, are especially critical in influencing adolescents to participate in volunteer service; however, no objective measures of this construct exist. Objectives: This study examined the psychometric properties of the Family, School, and Peer Influence on Volunteerism scale (FSPV) among Chinese…

The 24-item Physics Metacognition Inventory was developed to measure physics students' metacognition for problem solving. Items were classified into eight subcomponents subsumed under two broader components: knowledge of cognition and regulation of cognition. The students' scores on the inventory were found to be reliable and related to students'…

The Barkley Deficits in Executive Functioning Scale (BDEFS), authored by Russell A. Barkley and published by Guilford in 2011, is an individually administered assessment tool that may be used to evaluate adults ages 18 to 81. The purpose of this measure is to screen those who may be experiencing executive functioning (EF) deficits in…

This study presents the validation of a French version of the Career Adapt-Abilities Scale in four Francophone countries. The aim was to re-analyze the item selection and then compare this newly developed French-language form with the international form 2.0. Exploratory factor analysis was used as a tool for item selection, and confirmatory factor…

We report the development and psychometric evaluations of a self-report instrument designed to screen for psychopathic traits among mainstream community adolescents. Tests of item functioning were initially conducted with 26 adolescents. In a second study the new instrument was administered to 150 high school adolescents, 73 of who had school…

In this article we propose a model-free diagnostic for single-peakedness (unimodality) of item responses. Presuming a unidimensional unfolding scale and a given item ordering, we approximate item response functions of all items based on ordered conditional means (OCM). The proposed OCM methodology is based on Thurstone & Chave's (1929) "criterion…

Four maltreatment items were examined from Wave III (N = 13,516) of the National Longitudinal Study of Adolescent Health. Item analysis, confirmatory factor analysis, cross-validation, reliability estimates, and convergent validity coefficients strongly supported the validity of using the four items as a unidimensional composite. Implications for…

This study describes the development and psychometric properties of the Counseling Supervisor's Behavior Questionnaire, designed to assess the specific behaviors of supervisors, which can be observed by supervisees during supervision sessions. Factor structure, construct and concurrent validity, and internal consistency reliability of the…

Many psychological scales written in the Likert format include reverse worded (RW) items in order to control acquiescence bias. However, studies have shown that RW items often contaminate the factor structure of the scale by creating one or more method factors. The present study examines an alternative scale format, called the Expanded format,…

Strength-based assessment of behaviors in preschool children provides evidence of emotional and behavioral skills in children, rather than focusing primarily on weaknesses identified by deficit-based assessments. The Preschool Behavioral and Emotional Rating Scales (PreBERS) is a normative assessment of emotional and behavioral strengths in…

Learning paths have the potential to play an important role in the way educators serve their learners. Empirical research about learning paths is scarce, particularly in a secondary education setting. The present quasi-experimental study took place in the context of a biology course involving 360 secondary school students. A 2 × 2 factorial…

The study examined distance education as a tool for human resource development for junior secondary schools in Ebonyi State, Nigeria and it adopted a descriptive survey as the design. The population of the study consists of 2,410 secondary school teachers. Stratified simple random sampling technique was used to select 690 respondents. The…

High-stakes testing is used for the purposes of providing results that have important consequences. Validity is the cornerstone upon which all measurement systems are built. This study applied the Item Response Theory principles to analyse Northwest University Kano Post-UTME Economics test items. The developed fifty (50) economics test items was…

The purpose of this study was to establish the psychometric properties of the Attitudes Toward Research scale (ATR), including the validity of the scale through confirmatory factor analysis. After slightly altering the scale by deleting 19 items, and by narrowing down the subscales to four, the fit of the model was established. The revised version…

Objective: The purpose of this study was to develop a comprehensive health literacy assessment tool for young adult college students. Participants: Participants were 144 undergraduate students. Methods: Two hundred and twenty-nine questions were developed, which were based on concepts identified by the US Department of Health and Human Services,…
