Examined psychometric properties of Caregiver Inventory of Self-Concept (CISC) used with a largely Latino sample of 6- to 66-month-olds, and Tasks for Observation of Self-Concept (TOSC) used with 15- to 48-month-olds. Coefficient alpha and factor analysis provided evidence for test reliability and validity. Self-concept development followed…

Investigated the psychometric integrity of scores from the LibQUAL+ evaluation of perceived library service quality conducted by ARL (Association of Research Libraries). Examines score structure, score reliability, score correlation and concurrent validity coefficients, scale means, and scale standardized norms, and considers the potential of the…

This replication study continued the examination of the psychometric properties of the Foundation Practice Self-Efficacy scale (FPSE) with a sample of MSW students. As in the original study, evidence was found regarding the reliability, validity, and sensitivity to change of this measure. First, internal reliability estimates for the FPSE all…

This study examined the relationship between witness age, narrative features in testimony, and the perceived credibility of witnesses. Ninety older and young adult witnesses to a staged theft were videotaped as they freely recalled crime events. Later, participant-jurors viewed the videos and assessed the witnesses' credibility. Operational…

A series of studies extended psychometric research on the Adjustment Scales for Preschool Intervention (ASPI). The ASPI is a multidimensional measure of preschool emotional and behavioral adjustment for use within formal early childhood educational programs. These studies used a multiple method, multisource approach to provide additional evidence…

The reliability and construct validity of ratings for the Autism Behavior Checklist were examined with a sample of 198 children diagnosed with autistic disorder and conditions often confused with autism. Alpha coefficients for the five scales of the ABC as well as the Total Score were reported and the factor structure of the ABC was examined…

In recent years, ethics has become part of most tertiary biotechnology curricula. There is, however, considerable variation in the extent and manner of ethics education provided to students in different institutions. In addition, the perceived need that students and employers have regarding ethics education, and the aims and expected outcomes of…

The authors describe the preliminary development and validation of the Authenticity in Relationships Scale. An initial pool of 37 items addressing various elements of the proposed definition of "relationship authenticity" was administered to 2 independent samples of undergraduates (N = 487) who acknowledged being in a current romantic…

Many people believe in the value of outdoor experiential education opportunities such as organized camps for youth, but few instruments have been developed to measure the central youth development outcomes of camp. The purpose of this paper is to present the psychometric properties including the internal consistency and validity of scales designed…

Any programme of principal induction must find ways to respond to the diversity of its participants, in terms of their backgrounds and learning needs. New Zealand's national principal induction programme uses a self assessment of each principal's capability in the leadership of teaching and learning as one of its main sources of information about…

There is currently a lack of reliable scales with which to assess the construct of family quality of life, particularly for families who have children with disabilities. The current work presents 2 studies, including a total of 488 families with children with disabilities, which were conducted to complete the development of a scale to assess…

As item response theory (IRT) becomes popular in educational and psychological testing, there is a need of reporting IRT-based effect size measures. In this study, we show how the standardized mean difference can be generalized into such a measure. A disattenuation procedure based on the IRT test reliability is proposed to correct the attenuation…

Intraindividual variability in positive and negative affect was assessed by the positive affect (Contentment, Joy, Vigor, Love, and Excitement) and negative affect (Depression, Hostility, Anxiety, Agitation, and Social Anxiety) subscales of the state version of the Comprehensive Personality and Affect Scales (COPAS) during a 3-week period. Using…

The purpose of this study was to develop scales to assess instrumental help seeking, executive help seeking, perceived benefits of help seeking, and avoidance of help seeking and to examine their psychometric properties by conducting factor and reliability analyses. As this is the first attempt to examine the latent structures underlying the…

For a number of years, the dominant approach to measuring individual differences in how people respond to interpersonal conflict has been the dual-concerns model, which assesses five broad conflict styles said to result from one's standing on two underlying dimensions: concern for self and concern for other. This article describes the development…
