The Autism Spectrum Quotient (AQ) has been developed to measure the degree to which an adult with normal intelligence has autistic traits. In this paper it is evaluated for its potential as a screening questionnaire in clinical practice on one hundred consecutive referrals to a diagnostic clinic for adults suspected of having Asperger Syndrome or…

Recent psychometric results [Mem. Cogn. 29 (2001) 745] have supported a distinction between mental abilities that require a spatial transformation of a perceived object (e.g., mental rotation) and those that involve imagining how a scene looks like from different viewpoints (e.g., perspective taking). Two experiments provide further evidence for…

This study evaluated the psychometric properties of the Tourette's Disorder Scale-Parent Rated (TODS-PR), a 15-item parent-rated instrument that assesses a range of common symptoms seen in childhood Tourette's Disorder (TD) patients including tics, obsessions, compulsions, inattention, hyperactivity, aggression, and emotional disturbances.…

The present study was conducted to determine whether combining the results of multiple actuarial risk scales increases accuracy in predicting sex offender recidivism. Multiple methods of combining 4 validated actuarial risk scales--the Violence Risk Appraisal Guide, the Sex Offender Risk Appraisal Guide, the Rapid Risk Assessment for Sexual…

The authors applied contemporary methods from the evaluation literature to measure implementation in a residential treatment program for adolescent substance abuse. A logic model containing two main components was measured. Program structure (adherence to the intended framework of service delivery) was measured using data from daily activity logs…

One theoretical feature that makes item response theory (IRT) models those of choice for many psychometric data analysts is parameter invariance, the equality of item and examinee parameters from different examinee populations or measurement conditions. In this article, using the well-known fact that item and examinee parameters are identical only…

This paper examines the applicability of the learning organization concept and its measurement in a Chinese context. Based on the theoretical framework proposed by Watkins and Marsick (1993, 1996, 1997), this paper identifies the differences in seven of the Dimensions of Learning Organization Questionnaire (DLOQ) between traditional state-owned…

Direct observation plays an important role in the assessment practices of school psychologists and in the development of evidence-based practices in general and special education. The defining psychometric features of direct observation are presented, the contributions to assessment practice reviewed, and a specific proposal is offered for…

Curriculum-based measurement (CBM) procedures have been developed to assess mathematics computation (M-CBM). Recent research has demonstrated that the psychometric characteristics of measurement outcomes vary as a function of administration procedures. This study examined the effect of an alternate set of procedures to construct more consistent…

Objective/Method: The Sexual Abuse of Males Perceptions Scale (SAMPS) is a measure designed to assess an individual's personal and projected social perceptions of myths about the sexual abuse of boys and men. Myths are rigid, stereotypical beliefs that invalidate the experiences and minimize the profound effects of sexual abuse on boys and men.…

The class test is one of the important school practices which construct and convey to the pupils the predominant conception of ability and the related psychometric notion of individuality represented by the school. The aim of this study was to examine how the class test is actually "taught" to children--what sorts of elements the teacher…

The No Child Left Behind Act of 2001 includes requirements for annual state science assessments in elementary, middle, and high school. These assessments must be aligned with state academic content and achievement standards and involve multiple measures, including measures of higher-order thinking and understanding. This article addresses the…

Responsiveness to intervention (RTI) is being proposed as an alternative model for making decisions about the presence or absence of specific learning disability. We argue that many questions about RTI remain unanswered, and that radical changes in the proposed regulations are not warranted at this time. Since many fundamental issues related to…

The product of mental health counseling, unlike that of most professions, remains invisible to most people, leaving counselors vulnerable in a competitive market. The author argues that clinicians should recognize the value of, understand, and begin using outcome measures in their work. Research focusing on critical problems in psychotherapy…

The emergence of minimally intrusive techniques for collecting biological data creates a case for the inclusion of these data into bullying research models. This integration would produce a more comprehensive understanding of the problems and better direct intervention and prevention techniques, which are currently based primarily on self-report,…
