As researchers have examined the so-called "behavioral phenotypes" of different genetic mental retardation conditions, the measurement of behavior becomes increasingly important. From earlier, more global examinations of noteworthy behaviors or profiles, recent researchers have moved from reliance on a single, all-encompassing questionnaire to…

The MESSIER, a measure of social and communication skills and the Vineland Social Maturity Scale were administered to 618 severe and profoundly mentally retarded adults. The goal of the study was to establish the potential utility of the MESSIER for classifying level of intellectual disability in this group. Comparing MESSIER scores to previously…

To investigate the reliability and validity of the Yale Global Tic Severity Scale (YGTSS), 28 youth aged 6 to 17 years with Tourette's syndrome (TS) participated in the study. Data included clinician reports of tics and obsessive-compulsive disorder (OCD) severity, parent reports of tics, internalizing and externalizing problems, and child reports…

Structural equation modeling (SEM) offers a flexible method for studying the patterns of interdependence in partners' behavior, which lie at the heart of interactions and relationships. Although SEM has been applied to the study of distinguishable dyads, in which partners are distinguishable by type, such as male and female, it has rarely been…

The purpose of this investigation was to construct a theoretically driven and psychometrically sound childhood career development scale to measure career progress in fourth-through sixth-grade children. Super's nine dimensions (i.e., curiosity, exploration, information, key figures, interests, locus of control, time perspective, self-concept, and…

Researchers have a long-standing interest in better understanding why some students avoid challenging academic course work at the risk of harming their academic standing, whereas others are willing to pursue these types of challenges. The Academic Hardiness Scale (AHS) was developed to better understand characteristics that may differentiate these…

A 25-item self-report instrument was constructed to measure intrinsic motivation for academic work in the first-year student population. The instrument was based on a taxonomy of four types of intrinsic motivators: challenge, control, curiosity, and career outlook. The aim of this study was to provide reliability and validity evidence for the…

The reliability of the ACTFL Oral Proficiency Interview (OPI) has not been reported since ACTFL revised its speaking proficiency guidelines in 1999. Reliability data for assessments should be reported periodically to provide users with enough information to evaluate the psychometric characteristics of the assessment. This study provided the most…

One difficulty in monitoring the quality of family--professional partnerships has been the lack of a psychometrically acceptable and sufficiently general instrument with which to assess them. The current work describes the development of the Family--Professional Partnership Scale, which assesses parents' perceptions of the importance of and their…

The curriculum innovations in chemistry are often designed to address the important goals of improving student understanding and attitude, with assessment to determine the effects of these innovations. These analyses are psychometrically weak for several reasons, one reason being that the ability to look for the changes over time or for…

The present study investigated the transfer of induced happy and sad mood functions through equivalence relations. Sixteen subjects participated in a combined equivalence and mood induction procedure. In Phase 1, all subjects were trained in 2 conditional discriminations using a matching-to-sample format (i.e., A1-B1, A2-B2, A1-C1, A2-C2). In…

Developmental psychologists have been interested in the cognitive ability of perspective-taking for a number of years due to the apparent link between perspective-taking deficits and Autistic Spectrum Disorder. Most of the research in this area has employed the concepts and techniques of the approach commonly referred to as "Theory of Mind." The…

Documenting treatment integrity is an important issue in research and practice in any discipline concerned with prevention and intervention. However, consensus concerning the dimensions of treatment integrity and how they should be measured has yet to emerge. Advances from three areas in which significant treatment integrity work has taken…

The concept of treatment integrity cuts across a diversity of fields involved with providing treatments or interventions to individuals. In medical treatments, the concept of "treatment compliance" or "treatment adherence" is an important and problematic issue. In the field of nutrition, the concept of "dietary adherence" is important for…

End-of-course examinations are only as good as the assumptions used in designing them. What is a course's "essential" content? And what does it mean to master it? The end-of-course examinations developed by ACT are derived from assumptions that offer unique and challenging answers to these questions. This brief explains the process used to develop…
