The broad objective of this study was to understand the incidence and severity of aggression among sexually abused girls who were trafficked and who were then further used for commercial sexual exploitation (referred to subsequently as sexually abused trafficked girls). In addition, the impact of counseling for minimizing aggression in these girls…

In this classic introduction to educational and psychological measurement, Thorndike and Thorndike-Christ provide all of the pertinent information future professionals need to know in order to develop the skills to use test information wisely. Incorporating standard measurement concepts as they apply to both educational and psychological…

This study examined the association between female sexual offending behavioral patterns, as delineated by Sandler and Freeman's (2007) typologies, and executive functioning. The sample included all referrals for sexual offender assessments within a women's maximum/medium security prison between January 2009 and October 2009. Each subject was…

The Lothian Birth Cohort 1936 sample is in a uniquely good position to provide relevant data on social class mobility patterns over most of the last century. These participants, with known ultimate social class attainment, took a validated mental test in the Scottish Mental Survey of 1947 and were followed up at approximately age 70. Then, besides…

Background: The purpose of this study is to evaluate the relationship between brain tumour location and core areas of cognitive and behavioural functioning for paediatric brain tumour survivors. The extant literature both supports and refutes an association between paediatric brain tumour location and neurocognitive outcomes. We examined…

The Rorschach Inkblot Test has been the focus of intense controversy, significantly impacting clinicians who currently rely on Exner's Comprehensive System (CS; Exner, 2003) in clinical and forensic settings. This paper evaluates recent empirical CS research to determine whether or not it reveals lack of scientific merit as some skeptics have…

Orlando and Thissen's S-X[superscript 2] item fit index has performed better than traditional item fit statistics such as Yen' s Q[subscript 1] and McKinley and Mill' s G[superscript 2] for dichotomous item response theory (IRT) models. This study extends the utility of S-X[superscript 2] to polytomous IRT models, including the generalized partial…

This study investigates aspects of validity reflected in a large and diverse sample of published measures used in educational and psychological testing contexts. The current edition of "Mental Measurements Yearbook" served as the data source for this study. The validity aspects investigated included perspective on validity represented, number and…

A link between pre-morbid intelligence and all cause mortality is becoming well established, but the aetiology of the association is not understood. Less is known about links with cause specific mortality and with morbidity. The aim of this study is to examine the association between intelligence measured in adolescence and a broad range of health…

This study takes an individual differences' perspective on performance feedback effects in psychometric testing. A total of 105 students in a mainstream secondary school in North East England undertook a cognitive ability test on two occasions. In one condition, students received item-specific accuracy feedback while in the other (standard…

Samejima ("Psychometrika "65:319--335, 2000) proposed the logistic positive exponent family of models (LPEF) for dichotomous responses in the unidimensional latent space. The objective of the present paper is to propose and discuss a graded response model that is expanded from the LPEF, in the context of item response theory (IRT). This…

The TCU Short Forms contain a revised and expanded set of assessments for planning and managing addiction treatment services. They are formatted as brief (one-page) forms to measure client needs and functioning, including drug use severity and history (TCUDS II), criminal thinking and cognitive orientation (CTSForm), motivation and readiness for…

Ecological validity of neuropsychological assessment includes the ability of tests to predict real-world functioning and/or covary with brain structures. Studies have examined the relationship between adaptive skills and test performance, with less focus on the association between regional brain volumes and neurobehavioral function in healthy…

The author discusses the lives of Helen Bradford Thompson Woolley and M. Edith Campbell, who together shaped the legacy of the Vocational Bureau of Cincinnati. Using scientific research in controlled experimental settings allowed Woolley and Campbell to legitimize their social and vocational reform agendas and influence powerful government,…

Modern factor analysis is the outgrowth of Spearman's original "2-factor" model of intelligence, according to which a mental test score is regarded as the sum of a general factor and a specific factor. As early as 1914, Godfrey Thomson realized that the data did not require this interpretation and he demonstrated this by proposing what became…
