Objective: The Brown Location Test (BLT) was developed to remedy some of the problems in existing visual-based memory tests. The hand version has demonstrated good psychometric properties, the ability to provide lateralization information for mesial temporal lobe epilepsy patients, and has normative data. The purpose of this study was to compare the hand administered format to the more recently developed computer administered format. Methods: We used Generalizability Theory analyses to assess the degree of variability in scores across the hand and computer versions of the test, and across alternate test forms, A and B...

BACKGROUND: Valid instruments of parenting practices related to children's physical activity (PA) are essential to understand how parents affect preschoolers' PA. This study developed and validated a questionnaire of PA-related parenting practices for Chinese-speaking parents of preschoolers in Hong Kong. METHODS: Parents (n=394) completed a questionnaire developed using findings from formative qualitative research and literature searches. Test-retest reliability was determined on a sub-sample (n=61)...

Understanding variation in allele frequencies across populations is a central goal of population genetics. Classical models for the distribution of allele frequencies, using forward simulation, coalescent theory, or the diffusion approximation, have been applied extensively for demographic inference, medical study design, and evolutionary studies. Here we propose a tractable model of ordinary differential equations for the evolution of allele frequencies that is closely related to the diffusion approximation but avoids many of its limitations and approximations...

D J Castanelli, N A Smith
Background: The learning environment describes the context and culture in which trainees learn. In order to establish the feasibility and reliability of measuring the anaesthetic learning environment in individual departments we implemented a previously developed instrument in hospitals across New South Wales. Methods: We distributed the instrument to trainees from 25 anaesthesia departments and supplied summarized results to individual departments. Exploratory and confirmatory factor analyses were performed to assess internal structure validity and generalizability theory was used to calculate reliability...

BACKGROUND: There is a need for validated and easy-to-apply behavior-based tools for assessing interprofessional team competencies in clinical settings. The seven-item observer-based Modified McMaster-Ottawa scale was developed for the Team Objective Structured Clinical Encounter (TOSCE) to assess individual and team performance in interprofessional patient encounters. OBJECTIVE: We aimed to improve scale usability for clinical settings by reducing item numbers while maintaining generalizability; and to explore the minimum number of observed cases required to achieve modest generalizability for giving feedback...

BACKGROUND: The Functional Assessment of Cancer Therapy-Leukemia (FACT-Leu) scale, a leukemia-specific instrument for determining the health-related quality of life (HRQOL) in patients with leukemia, had been developed and validated, but there have been no reports on the development of a simplified Chinese version of this scale. This is a new exploration to analyze the reliability of the HRQOL measurement using multivariate generalizability theory (MGT). This study aimed to develop a Chinese version of the FACT-Leu scale and evaluate its reliability using MGT to provide evidence to support the revision and improvement of this scale...

OBJECTIVES: This investigation tests the theory of planned behavior (TPB) as a predictor of HIV testing intention among Nigerian university undergraduate students. METHODS: A cross-sectional study of 392 students was conducted using a self-administered structured questionnaire that measured socio-demographics, perceived risk of human immunodeficiency virus (HIV) infection, and TPB constructs. Analysis was based on 273 students who had never been tested for HIV. Hierarchical multiple regression analysis assessed the applicability of the TPB in predicting HIV testing intention and additional predictive value of perceived risk of HIV infection...

Network science and engineering provide a flexible and generalizable tool set to describe and manipulate complex systems characterized by heterogeneous interaction patterns among component parts. While classically applied to social systems, these tools have recently proven to be particularly useful in the study of the brain. In this review, we describe the nascent use of these tools to understand human cognition, and we discuss their utility in informing the meaningful and predictable perturbation of cognition in combination with the emerging capabilities of neurofeedback...

In this article, we illustrate how generalizability theory (G-theory) can extend traditional assessment methods for designing, improving, and evaluating results from both objectively and subjectively scored measures of individual differences. Our illustrations include quantification of multiple sources of measurement error, derivation of unique indexes of consistency for norm- and criterion-referenced interpretations of scores, estimation of score consistency when changing a measurement procedure, and disattenuation of correlation coefficients for measurement error...

#10
Alejandro Lleras, Hengqing Chu, Simona Buetti
Perceptual Load theory states that the degree of perceptual load on a display determines the amount of leftover attentional resources that the system can use to process distracting information. An important corollary of this theory is that the amount of perceptual load determines the vulnerability of the attention system to being captured by completely irrelevant stimuli, predicting larger amounts of capture with low perceptual load than with high perceptual load. This prediction was first confirmed by Forster and Lavie (2008)...

REVIEW
Peter Fonagy, Patrick Luyten, Elizabeth Allison, Chloe Campbell
This paper sets out a recent transition in our thinking in relation to psychopathology associated with personality disorder, in an approach that integrates our thinking about attachment, mentalizing (understanding ourselves and others in terms of intentional mental states) and epistemic trust (openness to the reception of social communication that is personally relevant and of generalizable significance) with recent findings on the structure of both adult and child psychopathology and resilience. In this paper - the first of two parts - we review evidence suggesting that a general psychopathology or p factor underlies vulnerability for psychopathology...

OBJECTIVE: Persistent complex bereavement disorder (PCBD) in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), has not been well studied in socioculturally diverse populations. Thus, this qualitative study examined (a) how widows in Nepal understand grief, (b) whether a local construct of PCBD exists, and (c) its comparability with the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), terminology. METHODS: Using an adapted Explanatory Model Interview Catalogue (EMIC) framework, semistructured interviews with 25 widows and 12 key informants, as well as three focus-group discussions (n = 20), were conducted between October 2014 and April 2015...

BACKGROUND AND PURPOSE: Current measures of missed nursing care employ inventories of tasks which are rated for the frequency with which each is missed. These lists have shortcomings for research and clinical evaluation. There is a need for measures with less response burden, wider generalizability, and greater sensitivity and specificity for identifying poor quality care. METHODS: We tested a single-item, global, measure using data from a large study of missed care in Australia...

Study Objectives: There is a long-standing debate about the best way to characterize performance deficits on the psychomotor vigilance test (PVT), a widely used assay of cognitive impairment in human sleep deprivation studies. Here, we address this issue through the theoretical framework of the diffusion model and propose to express PVT performance in terms of signal-to-noise ratio (SNR). Methods: From the equations of the diffusion model for one-choice, reaction-time tasks, we derived an expression for a novel SNR metric for PVT performance...

Interactions between short protein segments and phospholipid bilayers dictate fundamental aspects of cellular activity and have important applications in biotechnology. Yet, the lack of a suitable methodology for directly probing these interactions has hindered the mechanistic understanding. We developed a precision atomic force microscopy-based single-molecule force spectroscopy assay and probed partitioning into lipid bilayers by measuring the mechanical force experienced by a peptide. Protein segments were constructed from the peripheral membrane protein SecA, a key ATPase in bacterial secretion...

Schmidt decomposition is a widely employed tool of quantum theory which plays a key role for distinguishable particles in scenarios such as entanglement characterization, theory of measurement and state purification. Yet, its formulation for identical particles remains controversial, jeopardizing its application to analyze general many-body quantum systems. Here we prove, using a newly developed approach, a universal Schmidt decomposition which allows faithful quantification of the physical entanglement due to the identity of particles...

BACKGROUND: Research measuring physical activity behaviors during infancy is critical for evaluation of early intervention efforts to reduce rapid weight gain. There is little known about the physical activity patterns of infants, due in part to limited evidence for measurement procedures. This study sought to determine the minimal number of days and hours of accelerometry needed to reliably measure daily physical activity in infants using Generalizability (G) theory. METHODS: A total of 23 infants (14 F, 9 M) wore an accelerometer on the right ankle and right wrist for 7 days...

Most theories of lie detection assume that lying increases cognitive load, resulting in longer response latencies during questioning. However, the studies supporting this theory are typically laboratory-based, in settings with no specific validity in security contexts. Consequently, using virtual reality (VR), we investigated how response latencies were influenced in an ecologically valid environment of interest to security professionals. In a highly realistic airport security terminal presented in VR, a security officer asked participants yes/no questions about their belongings...

INTRODUCTION: Being able to understand other people's emotions and intentions is crucial for social interactions and well-being. Deficits in theory of mind (ToM) functioning hamper this ability and have been observed in depression and other neuropsychiatric disorders. However, results of previous research in depression have been inconclusive, possibly due to the presence of comorbid disorders and the disregarding of other modulating factors. METHODS: Thirty-eight patients with a major depressive disorder (MDD) and forty healthy matched controls were assessed with a ToM task using animated triangles...
