The Social Appearance Anxiety Scale (SAAS) was created to assess fear of overall appearance evaluation. Initial psychometric work indicated that the measure had a single-factor structure and exhibited excellent internal consistency, test-retest reliability, and convergent validity. In the current study, the authors further examined the factor,…

Evaluators are frequently asked to assess the effectiveness of school programs implemented to improve academic achievement. School connectedness has been shown to be directly related to academic achievement (McNeely, Nonnemaker, & Blum, 2002) and is therefore of interest to evaluators. The construct of school connectedness has been shown to…

Objective: This study examined test-retest reliability, internal consistency, and construct and predictive validity of the Physical Activity and Nutrition Self-Efficacy (PANSE) scale, an 11-item instrument to assess weight-loss self-efficacy among postpartum women of lower income. Methods: Seventy-one women completed the PANSE scale and…

The lack of available Spanish versions of assessment measures contributes to insufficient research and underutilization of mental health services for Latino children with Attention-Deficit/Hyperactivity Disorder (ADHD). Thus, the goal of the current study was to examine the psychometric and cultural properties of several Spanish versions of…

In this study the authors examine the effect respondent gender, victim age, and offender treatment programs have upon public attitudes towards sex offenders. A community sample of 235 participants were asked to read a hypothetical vignette involving the sexual assault of a 10-, 15-, or 20-year-old female by a 35-year-old male who subsequently…

This article examines the analysis of the psychometric properties, including the validity and reliability, of the Empathy Index (EI), a new instrument designed to measure empathy deficits of sex offenders. The EI was tested with a sample of 158 sex offenders incarcerated in North Carolina prisons. An exploratory factor analysis yielded three…

Effective teaching has long been an issue of national concern, but in recent years focus on the effectiveness of programs to produce high-quality teachers has sharpened. Long-standing achievement gaps persist despite large-scale legislative changes at the federal and state levels, and American students continue to show poorer performance on…

In a recent paper, Hessen ("Psychometrika" 70(3):497-516, 2005) introduces the class of constant latent odds-ratios models as an extension of the Rasch model for which the sum score is still the sufficient statistic for ability. In this paper the relation between both the general and the general parametric constant latent odds-ratios model and the…

We discuss properties that association coefficients may have in general, e.g., zero value under statistical independence, and we examine coefficients for 2x2 tables with respect to these properties. Furthermore, we study a family of coefficients that are linear transformations of the observed proportion of agreement given the marginal…

The association structure between manifest variables arising from the single-factor model is investigated using partial correlations. The additional insights to the practitioner provided by partial correlations for detecting a single-factor model are discussed. The parameter space for the partial correlations is presented, as are the patterns of…

Nambury S. Raju (1937-2005) developed two model-based indices for differential item functioning (DIF) during his prolific career in psychometrics. Both methods, Raju's area measures (Raju, 1988) and Raju's DFIT (Raju, van der Linden, & Fleer, 1995), are based on quantifying the gap between item characteristic functions (ICFs). This approach…

The current article reports the first attempt to test the Implicit Relational Assessment Procedure (IRAP), as a group-based measure of natural verbal relations, using both response-latency and event-related potentials as dependent variables. On each trial of the IRAP, participants were presented with 1 of 2 attribute stimuli ("Pleasant"…

There is a lack of valid and reliable low cost observational instruments to measure moderate to vigorous physical activity (MVPA) in school physical education (PE). The participants in this study were third to tenth grade boys and girls from a south Texas school district. The SAM (Simple Activity Measurement) activity levels were compared with…

This brief reviews the publicly available principal assessments and points superintendents and policy makers toward strong instruments to measure principal performance. Specifically, the measures included in this review are expressly intended to evaluate principal performance and have varying degrees of publicly available evidence of psychometric…

It is widely assumed that older adults suffer a deficit in the psychological processes that underlie remembering of contextual or source information. This conclusion is based in large part on empirical interactions, including disordinal ones, that reveal differential effects of manipulations of memory strength on recognition in young and old…
