The promotion of competency of nurses and other health-care professionals is a goal shared by many stakeholders. In nursing, observation-based assessments are often better suited than paper-and-pencil tests for assessing many clinical abilities. Unfortunately, few instruments for simulation-based assessment of competency have been published that have undergone stringent reliability and validity evaluation. Reliability analyses typically involve some measure of rater agreement, but other sources of measurement error that affect reliability should also be considered...

Reports an error in "Falsifiability is not optional" by Etienne P. LeBel, Derek Berger, Lorne Campbell and Timothy J. Loving (Journal of Personality and Social Psychology, 2017[Aug], Vol 113[2], 254-261). In the reply, there were two errors in the References list. The publishing year for the 14th and 21st articles was cited incorrectly as 2016. The in-text acronym associated with these citations should read instead as FER2017 and LCL2017. The correct References list citations should read as follows, respectively: Finkel, E...

A dominant paradigm in ecology is that plants are limited by nitrogen (N) during primary succession. Whether generalizable patterns of nutrient limitation are also applicable to metabolically and phylogenetically diverse soil microbial communities, however, is not well understood. We investigated if measures of N and phosphorus (P) pools inform our understanding of the nutrient(s) most limiting to soil microbial community activities during primary succession. We evaluated soil biogeochemical properties and microbial processes using two complementary methodological approaches-a nutrient addition microcosm experiment and extracellular enzyme assays-to assess microbial nutrient limitation across three actively retreating glacial chronosequences...

Best practices are currently being developed for the acquisition and processing of resting-state magnetic resonance imaging data used to estimate brain functional organization-or "functional connectivity." Standards have been proposed based on test-retest reliability, but open questions remain. These include how amount of data per subject influences whole-brain reliability, the influence of increasing runs versus sessions, the spatial distribution of reliability, the reliability of multivariate methods, and, crucially, how reliability maps onto prediction of behavior...

Explanation is a central concept in human psychology. Drawing upon philosophical theories of explanation, psychologists have recently begun to examine the relationship between explanation, probability and causality. Our study advances this growing literature at the intersection of psychology and philosophy of science by systematically investigating how judgments of explanatory power are affected by (i) the prior credibility of an explanatory hypothesis, (ii) the causal framing of the hypothesis, (iii) the perceived generalizability of the explanation, and (iv) the relation of statistical relevance between hypothesis and evidence...

Social support, in theory, should promote individual goal-pursuit. However, a growing number of studies shows that receiving support can undermine goal-pursuit. Addressing this paradox, we investigated a novel idea of the effects of how people think about their social support on their goal-pursuit. Four experiments showed that participants who were led to think abstractly (vs. concretely) about their social support showed higher intent to pursue their goal (Studies 1-3) and worked harder toward their goal (Study 4)...

BACKGROUND: Social cognition is severely impaired in schizophrenia. Emotion processing, attributional biases, and theory of mind are often impaired, as well as the understanding of shared social knowledge. So far, little is known about stereotype knowledge and endorsement in schizophrenia. SAMPLING AND METHODS: White patients with schizophrenia and matched healthy respondents reported both their personal beliefs and the predicted beliefs of other people toward Black (study 1) and Gypsy individuals (study 2)...

Quantitative ultrasound (QUS) is an inexpensive and promising tool for sensitive measurement of tendon pathology. However, few studies have reported the psychometric properties of measurements obtained using this technique for assessments of the supraspinatus tendon. The present study was undertaken to determine the variance contributed by several sources of error (participant, ultrasound operator, image analyst, analysis session) to QUS measures of the supraspinatus tendon. Transverse images of the supraspinatus tendon were captured from eleven subjects (22 shoulders) by two ultrasonographers, and each image was analyzed by two image analysts who each completed two analysis runs...

Gamma-band synchronization coordinates brief periods of excitability in oscillating neuronal populations to optimize information transmission during sensation and cognition. Commonly, a stable, shared frequency over time is considered a condition for functional neural synchronization. Here, we demonstrate the opposite: instantaneous frequency modulations are critical to regulate phase relations and synchronization. In monkey visual area V1, nearby local populations driven by different visual stimulation showed different gamma frequencies...

Although traditional economic and psychological theories imply that individual choice best scales to aggregate choice, primary components of choice reflected in neural activity may support even more generalizable forecasts. Crowdfunding represents a significant and growing platform for funding new and unique projects, causes, and products. To test whether neural activity could forecast market-level crowdfunding outcomes weeks later, 30 human subjects (14 female) decided whether to fund proposed projects described on an Internet crowdfunding website while undergoing scanning with functional magnetic resonance imaging...

Although quantitative designs are commonly used in clinical research, some studies require qualitative methods. These designs are different from quantitative methods; thus, researchers should be aware of data collection methods and analyses for qualitative research. Qualitative methods are particularly useful to understand patient experiences with the treatment or new methods of management or to explore issues in detail. These methods are useful in social and behavioral research. In qualitative research, often, the main focus is to understand the issue in detail rather than generalizability; thus, the sampling methods commonly used are purposive sampling; quota sampling; and snowball sampling (for hard to reach groups)...

The purpose of this study was to validate the already existing Racial Microaggression in Counseling Scale (RMCS) when the term 'therapist' was replaced with 'physician', thus constituting the modification as the Racial Microaggression in Medical Practice Scale (RMMPS). Racial microaggressions work at reinforcing inferior social status on a cognitive level. Unlike overt racism, messages behind microaggression are subtler and more every day. A lack of acceptance, respect, and regard emerges from interactions in medical contexts as there are layers of in-group and out-group statuses at play (e...

PURPOSE: The Myeloma Patient Outcome Scale (MyPOS) was developed to measure quality of life in routine clinical care. The aim of this study was to determine its longitudinal validity, reliability, responsiveness to change and its acceptability. METHODS: This 14-centre study recruited patients with multiple myeloma. At baseline and then every two months for 5 assessments, patients completed the MyPOS. Psychometric properties evaluated were as follows: (a) confirmatory factor analysis and scaling assumptions (b) reliability: Generalizability theory and Rasch analysis, (c) responsiveness and minimally important difference (MID) relating changes in scores between baseline and subsequent assessments to an external criterion, (d) determining the acceptability of self-monitoring...

Low concentrations of total 25-hydroxyvitamin D [25(OH)D], the principal biological measure of vitamin D status, have been associated with clinical and public health outcomes. The determination of levels under which there is an increase in the risk of disease, as well as comparisons across populations, have been difficult to establish due the large assay variability in measuring 25(OH)D. Accordingly, the Vitamin D Standardization Program (VDSP) includes the retrospective standardization of existing 25(OH)D values collected by epidemiological and clinical studies, as well as clinical trials, as one of its main objectives...

Finkel, Eastwick, and Reis (2016; FER2016) argued the post-2011 methodological reform movement has focused narrowly on replicability, neglecting other essential goals of research. We agree multiple scientific goals are essential, but argue, however, a more fine-grained language, conceptualization, and approach to replication is needed to accomplish these goals. Replication is the general empirical mechanism for testing and falsifying theory. Sufficiently methodologically similar replications, also known as direct replications, test the basic existence of phenomena and ensure cumulative progress is possible a priori...

BACKGROUND: While most psychiatric diagnoses are based on simple counts of symptoms, some symptoms may be sign of a more severe mental syndrome than others. This calls for validated estimates of the relative severity specific symptoms imply within a disorder. We focused on four diagnostic disorders: Manic Episode (ME), Major Depressive Episode (MDE), Post-traumatic Stress Disorder (PTSD) and Generalized Anxiety Disorder (GAD). Symptom-specific severity parameters were estimated, and validated by examining their association with levels of self-reported disability in daily activities over and above the number of symptoms...

BACKGROUND: Audit and feedback (AF) interventions that leverage routine administrative data offer a scalable and relatively low-cost method to improve processes of care. AF interventions are usually designed to highlight discrepancies between desired and actual performance and to encourage recipients to act to address such discrepancies. Comparing to a regional average is a common approach, but more recipients would have a discrepancy if compared to a higher-than-average level of performance...

Filipino adolescents are underrepresented in obesity research, although Filipinos are the second largest Asian-American and Pacific Islander (AAPI) subpopulation in the USA. An understanding of how well the theories of behavior change apply to Filipino and other AAPI adolescents is critical to addressing obesogenic behaviors in these groups. This study aimed to validate the transtheoretical model of behavior change (TTM) for physical activity (PA) and fruit and vegetable intake (FV) among a majority Filipino adolescent population...

Devices and programs using digital technology to foster or support behavior change (digital interventions) are increasingly ubiquitous, being adopted for use in patient diagnosis and treatment, self-management of chronic diseases, and in primary prevention. They have been heralded as potentially revolutionizing the ways in which individuals can monitor and improve their health behaviors and health care by improving outcomes, reducing costs, and improving the patient experience. However, we are still mainly in the age of promise rather than delivery...

Even though much has recently been learned about the neural representation of individual concepts and categories, neuroimaging research is only beginning to reveal how more complex thoughts, such as event and state descriptions, are neurally represented. We present a predictive computational theory of the neural representations of individual events and states as they are described in 240 sentences. Regression models were trained to determine the mapping between 42 neurally plausible semantic features (NPSFs) and thematic roles of the concepts of a proposition and the fMRI activation patterns of various cortical regions that process different types of information...
