The extent to which athletic pacing decisions are made consciously or subconsciously is a prevailing issue. In this article we discuss why the one-dimensional conscious-subconscious debate that has reigned in the pacing literature has suppressed our understanding of the multidimensional processes that occur in pacing decisions. How do we make our decisions in real-life competitive situations? What information do we use and how do we respond to opponents? These are questions that need to be explored and better understood, using smartly designed experiments...

OBJECTIVE: Perceived discrimination is an important risk factor for minority health. Drawing from the scholarship on multidimensionality of race, this study examines the relationships between perceived discrimination in health care and two dimensions of racial identity: self-identified race/ethnicity and perceived attributed race/ethnicity (respondents' perceptions of how they are racially classified by others). METHODS: We used Behavioral Risk Factor Surveillance System data collected in 2004-2013 and we specifically examined the data on perceived racial discrimination in health care during the past 12 months, perceived attributed race/ethnicity, and self-identified race/ethnicity...

Concept mapping served as the starting point for the aim of capturing the comprehensive structure of the construct of 'health literacy.' Ideas about health literacy were generated by 99 experts and resulted in 105 statements that were subsequently organized by 27 experts in an unstructured card sorting. Multidimensional scaling was applied to the sorting data and a two and three-dimensional solution was computed. The three dimensional solution was used in subsequent cluster analysis and resulted in a concept map of nine "clusters": (1) self-regulation, (2) self-perception, (3) proactive approach to health, (4) basic literacy and numeracy skills, (5) information appraisal, (6) information search, (7) health care system knowledge and acting, (8) communication and cooperation, and (9) beneficial personality traits...

BACKGROUND: Ankylosing spondylitis (AS) is an autoimmune rheumatic disease mostly affecting the axial skeleton. Currently, anti-tumour necrosis factor α (anti-TNF-α) represents an effective treatment for AS that may delay the progression of the disease and alleviate the symptoms if the diagnosis can be made early. Unfortunately, effective diagnostic biomarkers for AS are still lacking; therefore, most patients with AS do not receive timely and effective treatment. The intent of this study was to determine several key metabolites as potential biomarkers of AS using metabolomic methods to facilitate the early diagnosis of AS...

Developmental models of pediatric anxiety posit multiple, maladaptive parenting behaviors as potential risk factors. Despite this, a standardized means of assessing multiple of these practices (i.e., anxiogenic parenting) in a comprehensive and efficient manner are lacking. In Study 1531 parents of children 7-17 years old completed an online survey via Amazon Mechanical Turk. In Study 2, a separate community sample (N = 109; 9-17 years old) was recruited and completed a comprehensive assessment battery as part of a larger study...

BACKGROUND: The experiences of people with cancer and organ disease have been described across different dimensions of need as they approach death. Such information is lacking for frail older people approaching death, but could highlight how a palliative approach might be relevant for this population. METHODS: Cognitively intact, community dwelling adults considered to be moderately or severely frail were recruited from a medical day hospital. Those recruited nominated an informal carer and case-linked professional...

BACKGROUND: Previous studies of exercise have focused on measuring physical activity in totality using summary statistics such as metabolic equivalent score for total intensity or total energy count. OBJECTIVE: We aimed to examine the multidimensionality of leisure-time physical activity (LTPA) and to identify the specific LTPA components that were associated with cardiovascular mortality in the elderly. DESIGN AND PARTICIPANTS: The Northern Manhattan Study (NOMAS) is a multiethnic prospective cohort of elderly stroke-free individuals consisting of a total of 3298 participants recruited between 1993 and 2001, with a median follow-up of 17 years...

OBJECTIVES: To investigate the multidimensional gastrointestinal symptoms predictors of generic health-related quality of life (HRQOL) in pediatric patients with inflammatory bowel disease (IBD) from the perspectives of pediatric patients and parents. METHODS: The Pediatric Quality of Life Inventory (PedsQL) Gastrointestinal Symptoms Scales and PedsQL 4.0 Generic Core Scales were completed in a 9-site study by 260 families of patients with IBD. Gastrointestinal Symptoms Scales measuring stomach pain, food and drink limits, gas and bloating, constipation, blood in stool, and diarrhea were identified as clinically important symptom differentiators from healthy controls based on prior findings, and subsequently tested for bivariate and multivariate linear associations with overall HRQOL (Generic Core Scales)...

OBJECTIVE: There is growing recognition in psychology that wellness is more than the absence of disease and distress. Well-being has been defined in numerous ways. Two dominant models include Diener, Eunkook, Suh, Lucas and Smith's (1999) model of subjective well-being (SWB) and Ryff's (1989) model of psychological well-being (PWB). In contrast to the abundance of research investigating negative constructs and psychopathology in chronic fatigue syndrome (CFS), there has been a paucity of positive psychology studies...

PURPOSE: To assess cataract surgery outcome using the Rasch scaled Chinese version of the Catquest short-form. METHODS: The Chinese translated and culturally adapted version of the Catquest-9SF was interviewer-administered to patients, pre and post cataract surgery. Rasch analysis was performed on the baseline data to revise the Catquest. For the surgical outcome assessment, we stacked pre- and post-surgical Catquest data to demonstrate improvement in visual function scores and responsiveness of the instrument to cataract surgery...

The authors used a state-trace methodology to investigate the informational dimensions used to recognize old and conjunction faces (made by combining parts of separately studied faces). Participants in 3 experiments saw faces presented for 1 s each. They then received a recognition test; faces were presented for varying brief durations and participants made 3 responses: old/new judgments, confidence judgments, and an indication of whether each response was based on memory for a feature or in general familiarity...

BACKGROUND: HCV treatment among people who inject drugs (PWID) is low. Education programs may be suitable strategies to improve patients' knowledge about their condition and to overcome barriers to access treatment. METHODS: The Health Educational Program (HEP) consisted of patient workshops and educational videos and leaflets, and healthcare professionals' workshops. HEP was implemented at seven substance dependence treatment centers (STDC) in Portugal. The study comprised two cross-sectional evaluations conducted before and after HEP...

Fatigue is one of the most commonly reported sequelae after traumatic brain injury (TBI). This study evaluated the impact of a graduated physical activity programme on fatigue after TBI. Using a prospective randomised single-blind crossover design, 123 individuals with TBI, over the age of 18, were enrolled. Interventions included a home-based walking programme utilising a pedometer to track daily number of steps at increasing increments accompanied by tapered coaching calls over a 12-week period. Nutritional counselling with the same schedule of coaching calls served as the control condition...

G-factor models such as the bifactor model and the hierarchical G-factor model are increasingly applied in psychology. Many applications of these models have produced anomalous and unexpected results that are often not in line with the theoretical assumptions on which these applications are based. Examples of such anomalous results are vanishing specific factors and irregular loading patterns. In this article, the authors show that from the perspective of stochastic measurement theory anomalous results have to be expected when G-factor models are applied to a single-level (rather than a 2-level) sampling process...

The title reaction is involved in the formation of ammonia in the interstellar medium. We have calculated thermal rates including atom tunnelling using different rate theories. Canonical variational theory with microcanonically optimised multidimensional tunnelling was used for bimolecular rates, modelling the gas-phase reaction and also a surface-catalysed reaction of the Eley-Rideal type. Instanton theory provided unimolecular rates, which model the Langmuir-Hinshelwood type surface reaction. The potential energy was calculated on the CCSD(T)-F12 level of theory on the fly...

Empowerment-based strategies have become widely used method to address health inequities and promote social change. Few researchers, however, have tested theoretical models of empowerment, including multidimensional, higher-order models. We test empirically a multidimensional, higher-order model of psychological empowerment (PE), guided by Zimmerman's conceptual framework including three components of PE: intrapersonal, interactional, and behavioral. We also investigate if PE is associated with positive and negative outcomes among youth...

Today well-being attracts the attention of public health professionals who are looking to explore life satisfaction as a whole and its specific domains. In order to contribute in moving the measurement of subjective well-being from a primarily academic activity to the sphere of intervention, we need to assess tools to measure multidimensional well-being (MWB) adopting state-of-the-art statistical techniques. Through structural equation modelling our goal was to test a MWB model among Italian and Serbian university students and to further observe its relationships with measures of life goals' pursuing...

BACKGROUND: The widespread adoption of electronic health records allows us to ask evidence-based questions about the need for and benefits of specific clinical interventions in critical-care settings across large populations. OBJECTIVE: We investigated the prediction of vasopressor administration and weaning in the intensive care unit. Vasopressors are commonly used to control hypotension, and changes in timing and dosage can have a large impact on patient outcomes...
