Background: Those who stutter have a proclivity to social anxiety. Yet, to date, there is no comprehensive measure of thoughts and beliefs about stuttering that represent the cognitions associated with that anxiety. Aims: The present paper describes the development of a measure to assess unhelpful thoughts and beliefs about stuttering. Methods &…

The authors present the results of a validity and reliability study for the Group Leadership Effectiveness Scale (GLES). Seven consecutive semesters of data were gathered for this investigation, with 1 semester of data being reported and analyzed here. The results of the data support both validity and reliability for this instrument. A…

The measurement of physical fitness of lower limb amputees is difficult, as the commonly used ergometer tests have limitations. A combined arm-leg (Cruiser) ergometer might be valuable. The aim of this study was to establish the repeatability and validity of the combined arm-leg (Cruiser) ergometer. Thirty healthy volunteers carried out three…

The impacts of incorrect responses to reverse-coded survey items were examined in this simulation study by reversing responses to traditional Likert-format items from 700 administrators in randomly selected schools in a 7-county region in central Arkansas that were obtained from an archival dataset. Specifically, the number of reverse-coded items…

Background: The purpose of this study was to develop and test the reliability of self-report survey items designed to monitor the nonmedical use of prescription drugs among adolescents. Methods: Eighteen nonmedical prescription drug items designed to be congruent with the substance abuse items in the US Centers for Disease Control and Prevention's…

In three experiments (N = 123; 148; 28), children observed a video in which two speakers offered alternative labels for unfamiliar objects. In Experiment 1, 3- to 5-year-olds endorsed the label given by a speaker who had previously labeled familiar objects accurately, rather than that given by a speaker with a history of inaccurate labeling, even…

Disconnection from the natural world may be contributing to our planet's destruction. The authors propose a new construct, Nature Relatedness (NR), and a scale that assesses the affective, cognitive, and experiential aspects of individuals' connection to nature. In Study 1, the authors explored the internal structure of the NR item responses in a…

The impact of biotechnologies on peoples' everyday lives continuously increases. Measuring young peoples' attitudes toward biotechnologies is therefore very important and its results are useful not only for science curriculum developers and policy makers, but also for producers and distributors of genetically modified products. Despite of…

The three algorithms most frequently selected by behavior-analytic researchers to compute interobserver agreement with continuous recording were used to assess the accuracy of data recorded from video samples on handheld computers by 12 observers. Rate and duration of responding were recorded for three samples each. Data files were compared with…

In response to the shift from a system-centred care model to a person-centred support model, the Supports Intensity Scale (SIS) has been developed as an instrument to assess the support needs of persons with intellectual disabilities. The instrument is used as a tool for constructing individual support plans, as well as a tool for resource…

Background: A program of research is needed that assesses the psychometric properties of instruments designed to quantify students' achievement goal orientations to clarify inconsistencies across previous studies and to provide a stronger basis for future research. Aim: We conducted traditional psychometric and modern Rasch-model analyses of the…

The assessment of maintaining variables with the goal of developing prosocial intervention plans has become a driving force in the intellectual disabilities (ID) literature. One particularly crucial variable is whether the behavior is low or high rate and whether the challenging behavior is best characterized by self-injury or aggression. Because…

A wide range of experimental studies have provided evidence that a night of sleep may enhance motor performance following physical practice (PP), but little is known, however, about its effect after motor imagery (MI). Using an explicitly learned pointing task paradigm, thirty participants were assigned to one of three groups that differed in the…

In an effort to standardize academic application procedures, the authors developed the Standardized Letters of Recommendation (SLR) to capture important cognitive and noncognitive qualities of graduate school candidates. The SLR, which consists of seven scales, is applied to an intern-selection scenario. Both professor ratings (n = 414) during the…

Test worry and emotionality can substantially affect student performance on examinations, and research has shown the deleterious effects of untreated test anxiety. A recently developed measure, the Test and Study Attitudes Inventory (TSAI), has shown promise in the measurement of both test and study related worry and emotionality. The purpose of…
