This study examines the level of acceptance of a robot within the elderly. ’Does more knowledge of a robot lead to a higher level of acceptance?’ Scenarios based on assistive technologies have been developed for this study. These scenarios provided knowledge to the two groups which were defined as Group A and Group B. The difference between the groups was the order in which the experiment was c...

The current study aimed at exploring the knowledge and beliefs of men aged forty years and over towards prostate cancer screening and early detection in three Arab countries. The field work was conducted in three countries; Saudi Arabia, Egypt and Jordan, during the period February through December 2011. Our target population were men aged 40 years and over. It was a population-based cross sect...

Context: Psychosocial exposures commonly show large variation over time and are usually assessed using multiitem Likert indices. A construct requiring a five-item Likert index could possibly be replaced by a single visual analogue scale (VAS). Objective: To: a) evaluate validity and relative reliability of a single VAS compared to previously validated Likert based items and indices measuring th...

Likert items and scales are often used in human subject studies to measure subjective responses of subjects to the treatment levels. In the field of human-robot interaction (HRI), with few widely accepted quantitative metrics, researchers often rely on Likert items and scales to evaluate their systems. However, there is a debate on what is the best statistical method to evaluate the differences...

To the Editor: I read with interest the recent article by Baker regarding the value of normalizing resident evaluation scores to eliminate individual faculty evaluator bias. Without unduly undermining the importance of this study, I have concern about the statistical handling of Likert scores. Likert scores were used to create individual faculty member mean scores, faculty score standard deviat...

Dipping my toe into the water of educational research, I have recently used Likert-type rating scales to measure student views on various educational interventions. Likert scales are commonly used to measure attitude, providing a range of responses to a given question or statement . Typically, there are 5 categories of response, from (for example) 1 1⁄4 strongly disagree to 5 1⁄4 strongly agree...

OBJECTIVE We investigated elementary school children's ability to use a variety of Likert response formats to respond to concrete and abstract items. METHODS 111 children, aged 6-13 years, responded to 2 physical tasks that required them to make objectively verifiable judgments, using a 5-point response format. Then, using 25 items, we ascertained the consistency between responses using a "go...

The current study investigates the optimum number of response categories for Likert type scales under item theory (IRT). data was collected from university students attend to mainly faculty medicine and education. A form “Social Gender Equity Scale” developed by Gozutok et al. (2017) prepared, which had 3, 5 7-point categories. graded model (GRM) used calibrations. results have revealed that us...

In assessments of attitudes, personality, and psychopathology, unidimensional scale scores are commonly obtained from Likert scale items to make inferences about individuals' trait levels. This study approached the issue of how best to combine Likert scale items to estimate test scores from the practitioner's perspective: Does it really matter which method is used to estimate a trait? Analyses ...
