The sense of touch and proprioception are critical to movement control. After spinal cord injury, these senses may be restored with direct, electrical microstimulation of the brain as part of a complete sensorimotor neuroprosthesis. The present study was designed to test, in part, the hypothesis that the cuneate nucleus (CN) of the brainstem is a suitable site to encode somatosensory information. Two rhesus macaques were implanted with microelectrode arrays providing chronic access to the CN. The monkeys were trained on an active touch oddity task to detect vibrotactile stimuli...

The automation and systemisation of the next generation of cognitive assessment approaches have the potential to change how clinicians assess and interact with patients. This may be especially pertinent in the case of delirium, as current methods often rely on the subjective opinion of clinicians and specialists, with potential for the condition to be overlooked or misdiagnosed. Currently, one of the most commonly used tests, is the clock-drawing test, which has relatively wide appeal as a cognitive screening instrument due to its clinical utility and psychometric properties...

The NCLEX-RN® was adopted by Canadian regulators in 2011 as the test which entry-level nurses must pass in order to be certified to practice. As part of their justification for adopting the exam, the Canadian regulators pointed to two studies conducted by the National Council of State Boards of Nursing (NCSBN). These studies aimed to determine the applicability of the NCLEX-RN® test plan to the Canadian testing population (NCSBN, 2014),with the NCLEX-RN® providing "a fair, valid, and psychometrically sound measurement" of nursing competencies of entry-level RNs in Ontario, Canada (NCSBN, 2012 , p...

Although widely used, the Hamilton Rating Scale for Depression (HRSD) and Hamilton Anxiety Rating Scale (HARS) discriminate poorly between depression and anxiety. To address this problem, Riskind, Beck, Brown, and Steer (J Nerv Ment Dis. 175:474-479, 1987) created the Reconstructed Hamilton Scales by reconfiguring HRSD and HARS items into modified scales. To further analyze the reconstructed scales, we examined their factor structure and criterion-related validity in a sample of patients with major depressive disorder and no comorbid anxiety disorders (n = 215) or with panic disorder and no comorbid mood disorders (n = 149)...

Aims: Large-scale epidemiological studies show a significant prevalence of gambling disorder (GD) during adolescence and emerging adulthood, and highlight the need to identify gambling-related behaviors at early ages. However, there are only a handful of screening instruments for this population and many studies measuring youth gambling problems use adult instruments that may not be developmentally appropriate. The aim of this study was to validate a Spanish version of the Canadian Adolescent Gambling Inventory (CAGI) among late adolescent and young adults and to explore its psychometric properties...

BACKGROUND: Patients with back and neck pain are often seen in primary care and it is important to provide them with tailored interventions based on risk stratification/triage. The STarT Back Screening Tool (SBT) is a widely used screening questionnaire which has not yet been validated for a population with back and/or neck pain with short duration. Our aim was to compare the concurrent validity of the SBT and the short form of the ÖMPSQ including psychometric properties and clinical utility in a primary care setting...

Recent translational research developments in Spinal Muscular Atrophy (SMA), outcome measure design and demands from regulatory authorities require that clinical outcome assessments are 'fit for purpose'. An international collaboration (SMA REACH UK, Italian SMA Network and PNCRN USA) undertook an iterative process to address discontinuity in the recorded performance of the Hammersmith Functional Motor Scale Expanded and developed a revised functional scale using Rasch analysis, traditional psychometric techniques and the application of clinical sensibility via expert panels...

Novelty-seeking tendencies in adolescents may promote innovation as well as problematic impulsive behaviour, including drug abuse. Previous research has not clarified whether neural hyper- or hypo-responsiveness to anticipated rewards promotes vulnerability in these individuals. Here we use a longitudinal design to track 144 novelty-seeking adolescents at age 14 and 16 to determine whether neural activity in response to anticipated rewards predicts problematic drug use. We find that diminished BOLD activity in mesolimbic (ventral striatal and midbrain) and prefrontal cortical (dorsolateral prefrontal cortex) regions during reward anticipation at age 14 predicts problematic drug use at age 16...

BACKGROUND: Health literacy enables effective communication, participation, and cooperation with clinicians of patients with breast cancer in healthcare processes. The European Health Literacy Survey Questionnaire (HLS-EU-Q) comprehensively assesses multiple conceptual domains of health literacy in a diverse range of health contexts. However, the HLS-EU-Q has not been validated in women with breast cancer. OBJECTIVES: We examined the psychometric properties, particularly the factorial validity, of the HLS-EU-Q in women with breast cancer...

Generalized anxiety disorder (GAD) is a mental disorder of which the main feature is persistent and impairing worry. GAD symptoms are common for women during the postpartum period and GAD prevalence rates have been reported as higher in postpartum mothers than in the general population. Currently, little psychometric evidence exists for a screening measure to detect the possible presence of diagnosable GAD for postpartum women. The purpose of this investigation was to gather psychometric information for the Generalized Anxiety Disorder Questionnaire-IV (GAD-Q-IV; Newman et al...

AIMS: We validated a Turkish language version of the urethral stricture surgery specific patient-reported outcome measure (USS-PROM) in men undergoing anterior urethroplasty. We also investigated changes in erectile function (EF) and quality of life (QoL) due to oral mucosa graft (OMG) harvesting. METHODS: The USS-PROM captures lower urinary tract symptoms (LUTS), health related QoL (HRQoL) with EQ-5D visual analogue scale (EQ-VAS). To evaluate EF and OMG morbidity, we used International Index of Erectile Function (IIEF-5) and a self-completed questionnaire, respectively...

Saskia Jaarsveld, Thomas Lachmann
This paper discusses the importance of three features of psychometric tests for cognition research: construct definition, problem space, and knowledge domain. Definition of constructs, e.g., intelligence or creativity, forms the theoretical basis for test construction. Problem space, being well or ill-defined, is determined by the cognitive abilities considered to belong to the constructs, e.g., convergent thinking to intelligence, divergent thinking to creativity. Knowledge domain and the possibilities it offers cognition are reflected in test results...
