Internal (Factorial) Validity of the ANAM using a Cohort of Woman High-School Soccer Players

Introduction Computerized neuropsychological testing is a cornerstone of sport-related concussion assessment. Female soccer players are at an increased risk for concussion as well as exposures to repetitive head impacts from heading a soccer ball. Our primary aim was to examine factorial validity of the Automated Neuropsychological Assessment Metrics (ANAM) neuropsychological test battery in computing the multiple neurocognitive constructs it purports to measure in a large cohort of interscholastic female soccer players. Methods Study participants included 218 interscholastic female soccer players (age = 17.0±0.7 year; mass = 55.5±6.8 kg; height = 164.7±6.6 cm) drawn from a large (850+) prospective database examining purposeful heading from four area high schools over a 10-year period. The ANAM-2001 measured neurocognitive performance. Three methods were used to identify integral constructs underlying the ANAM: (a) exploratory factor analysis (EFA), (b) first-order confirmatory factor analysis (CFA), and (c) hierarchical CFA. Results Neuropsychological phenomena measured by the ANAM-2001 were best reproduced by a hierarchical CFA organization, composed of two lower level factors (Simple Reaction Time, Mental Efficiency) and a single, general composite. Although the ANAM was multidimensional, only the composite was found to possess sufficient construct dimensionality and reliability for clinical score interpretation. Findings failed to uphold suppositions that the ANAM measures seven distinct constructs, or that any of its seven tests provide unique information independent of other constructs, or the composite, to support individual interpretation. Conclusions Outcomes infer the ANAM possesses factorial-validity evidence, but only scores from the composite appear to sufficiently internally valid, and reliable, to support applied use by practitioners.

Pengaruh Kesehatan Mental, Keaktifan Berorganisasi dan Prestasi AkademikTerhadap Tingkat Pemahaman Moderasi Beragama

This research is quantitative research with the design of research hypothesis testing studies aimed at analyzing, describing, and obtaining empirical evidence of a pattern of relations between two or more variables, both correlational (correlation), causality and comparatively (comparative). This research aims to seek direct influence and indirect influence between mental health, active organization and academic achievement of students (independent variables) with the level of understanding of religious moderation (variable dependent). Samples in the study of 86 people. The method of collecting data used for mental health variables is to use a validated mental efficiency test from an official institution/hospital/a credible psychologist. While the learning achievement variables are taken from the student learning documentation. The active variables of the organization and the level of understanding of religious moderation are the poll methods. The poll used is a closed poll that has provided the answer. Test the significance of the influence of variables independent of the dependent variables simultaneously using the F test and partially using the T test.

The secret of quick thinking: The invention of mental speed in America, 1890–1925

In the early 20th century, mental speed became a dominant measure of intelligence in the United States. For both cultural and technical reasons, this had not always been the case. For 19th-century Americans, quickness of speech and thought often signified lack of self-discipline. Unlike with other objects of temporal measurement and rationalization such as factory work, little scientific or popular consensus existed over how to clock the invisible phenomenon of thought. The cultural and scientific ascent of mental speed thus poses an unsolved historical problem: how and why did Americans adopt this new ideal of intelligence? This essay offers an answer in the introduction and popularization of a new and controversial practice: the timed test. The first timed tests did not so much formalize an existing conception of mental efficiency as establish a new one, using one of the key tools of measurement available to experimental psychology, the mechanical time-keeper. Initially frustrated in their efforts to correlate their subjects' laboratory-measured reaction time with socially recognized achievements such as academic grades, psychologists in the late 1890s borrowed a still-obscure concept from stenography and telegraphy: words per minute. At first, few scientists or members of the public equated reading, speaking, writing, and listening rate with intelligence. Only after American educators, military recruiters, and vocational guidance experts began to adopt timed testing in the 1910s for administrative convenience did mental speed begin to indicate intelligence and knowledge. What began as a way to test minds efficiently evolved almost inadvertently into a test of their efficiency.

Hygienic assessment of handicapped adolescents vocational training conditions: problems and optimization opportunities

In a number of occupations, there is a shortage of labor force that can be filled with economically active part of the population, including people with disabilities (handicapped, HC). Unfortunately, observance of hygienic requirements in the context of HP adolescents vocational training has not been studied sufficiently: most scholars have researched only the conditions of teaching healthy adolescents. This study aimed to examine the HC adolescents vocational training conditions and develop measures to improve their working conditions with pathologies factored in. We examined adaptation potential, anxiety level, mental efficiency, sick rate and personal well-being assessment in HC adolescents (n = 120) aged 16–18, not impaired intellectually, studying sewing equipment operation, shoe repairs in the boarding scool. In the context of the study, we applied Smirnov hygiene criteria, Giessen Symptom Questionnaire, Spielberger's Test Anxiety Questionnaire, Sivkov scale, correction tables, Baevsky adaptation index. For the purposes of statistical analysis, we used parametric (Student t-test) and non- parametric (Mann–Whitney) criteria. The Spearman's correlation coefficient helped determine interrelationship of the studied parameters. We identified the following key adverse hygienic factors that have a significant impact on the students' health: intense character of labor performed, insufficient artificial lighting, noise level above the norm, high content of organic solvents and dust in the workshop's air. The timetable of the boarding school was also found to be inefficient. The results of this study allowed developing and introducing a software program to automatically compile the school's timetable with the aim to improve psychosomatic health of the students and halve the number of health-related complaints.

Enhancing health leadership performance using neurotherapy

The discovery of neuroplasticity means the brain can change, functionally, in response to the environment and to learning. While individuals can develop harmful patterns of brain activity in response to stressors, they can also learn to modify or control neurological conditions associated with specific behaviors. Neurotherapy is one way of changing brain functioning to modify troubling conditions which can impair leadership performance, through responding to feedback on their own brain activity, and enhancing optimal leadership functioning through learning to maximize such cognitive strengths as mental efficiency, focus, creativity, perseverance, and executive functioning. The present article outlines the application of the concept of optimal performance training to organizational leadership in a healthcare context, by describing approaches to neurotherapy and illustrating their application through a case study of a health leader learning to overcome the neurological and emotional sequelae of workplace stress and trauma.
