BACKGROUND Psychometric properties include validity, reliability and sensitivity to change. Establishing the psychometric properties of an instrument which measures three-dimensional human posture are essential prior to applying it in clinical practice or research. METHODS This paper reports the findings of a systematic literature review which aimed to 1) identify non-invasive three-dimension...

BACKGROUND The prevalence of unplanned pregnancy in Saudi Arabia has not been thoroughly investigated. OBJECTIVE To conduct a psychometric evaluation study of the Arabic version of the London Measure of Unplanned Pregnancy (LMUP). METHODS To evaluate the psychometric properties of the LMUP, we conducted a self-administered online survey among 796 ever-married Saudi women aged 20-49 years, a...

Knowledge present in a domain is well expressed as relationships between corresponding concepts. For example, zoology, animal species form complex hierarchies; genomics, the different (parts of) molecules are organized groups and subgroups based on their functions; plants, molecules, astronomical objects all taxonomies. Nevertheless, when applying supervised machine learning (ML) such domains, ...

BACKGROUND Psychometric tests predict conversion of mild cognitive impairment (MCI) to probable Alzheimer's disease (AD). Because the definition of clinical AD relies on those same psychometric tests, the ability of these tests to identify underlying AD pathology remains unclear. OBJECTIVE To determine the degree to which psychometric testing predicts molecular evidence of AD amyloid patholog...

INTRODUCTION Tests of upper-extremity motor function used for people following a stroke have been described, but reliability and validity (psychometric properties) of measurements obtained with these tests have not been consistently established. This investigation was performed: (1) to review literature relative to upper-extremity motor function testing during rehabilitation following a stroke,...
