Screen time among adults represents a continuing and growing problem in relation to health behaviors and health outcomes. However, no instrument currently exists in the literature that quantifies the use of modern screen-based devices. The primary purpose of this study was to develop and assess the reliability of a new screen time questionnaire, an instrument designed to quantify use of multiple popular screen-based devices among the US population.

Perceptual timing tasks are frequently applied in research on developmental disorders, but information on their reliability is lacking in pediatric studies. We therefore aimed to assess the reliabilit...
An important challenge in Parkinson's disease research is how to measure disease progression, ideally at the individual patient level. The MDS-UPDRS, a clinical assessment of motor and nonmotor impair...
To assess the convergent validity and reliability of joint angle measurements from a new video goniometer iPhone/iPad application (app) separately in adults, older and young children.
The influence of screens and technology on adolescent well-being is controversial and there is a need to improve methods to measure these behaviors. This study examines the feasibility and acceptabili...
Auditory steady-state response (ASSR) paradigms have consistently demonstrated gamma band abnormalities in schizophrenia at a 40-Hz driving frequency with both electroencephalography (EEG) and magneto...
This study will prospectively examine the effect of screen time on recovery from concussion. Patients 12 to 25 years of age presenting to the ED with a concussion will be randomized to all...
The purpose of this pilot experiment is threefold. 1. To assess the efficacy of the recruitment strategy 2. To assess the acceptability and feasibility of the outcome measurement met...
The overall aim of the study is to assess the reliability and validity of Autocad software to measure JPS in PFPS, especially: 1. To assess the intra-tester and between day reliability ...
Phantom limb pain (PLP) is experienced by 60-80% of all people who have had an amputation. This persistent pain condition can impact on independence, activities of daily living and overall...
The 3 m walk-back test is used to assess neuromuscular control, proprioception, protective reflexes, fall risk, and balance. In a study of healthy elderly adults, a 3-m walk-back test show...
Measure of the burden of disease using the disability-adjusted-life-year (DALY). This time-based measure combines years of life lost due to premature mortality and years of life lost due to time lived in states of less than full health. The metric was developed to assess the burden of disease consistently across diseases, risk factors and regions.
Screens which absorb the energy in the x-ray beam that has penetrated the patient and convert this energy into a light pattern which has as nearly as possible the same information as the original x-ray beam. The more light a screen produces for a given input of x-radiation, the less x-ray exposure and thus shorter exposure time are needed to expose the film. In most film-screen systems, the film is sandwiched between two screens in a cassette so that the emulsion on each side is exposed to the light from its contiguous screen.
Tests designed to measure intellectual functioning in children and adults.
Devices used to assess the level of consciousness especially during anesthesia. They measure brain activity level based on the EEG.
Duration of blood flow after skin puncture. This test is used as a measure of capillary and platelet function.
