In Brief Objective Although research has been conducted on how nurse staffing levels affect outcomes, there little investigation into the health-related productivity of nurses is related to quality care. Two major causes worker presenteeism (reduced on-the-job as a result health problems) are musculoskeletal pain and mental issues, particularly depression. This study sought investigate extent which or depression (or both) in RNs affects their work self-reported care considered associated...

Abstract Kadilar and Cingi [Ratio estimators in simple random sampling, Appl. Math. Comput. 151 (3) (2004), pp. 893–902] introduced some ratio-type of finite population mean under sampling. Recently, [New ratio using correlation coefficient, Interstat 4 (2006), 1–11] have suggested another form by modifying the estimator developed Singh Tailor [Use known coefficient estimating mean, Stat.

Randomized response technique (RRT) surveys are designed to secure honest answers sensitive questions. In this study, we consider the important issue of measurement error (ME). While non-response, a common culprit for survey inaccuracy, is lesser in RRT studies because they conducted through face-to-face interviews, particular significance. models generally more complex than other methods, sometimes requiring that respondents follow ordered instructions, draw cards from decks, and/or perform...

Gupta et al. [2] used a Randomized Response Technique (RRT) to propose several estimators for finite population variance of sensitive study variable using auxiliary information. In this paper, we modify those by the more efficient form RRT, namely, Optional (ORRT). Performance proposed is evaluated unified measure respondent privacy and estimator efficiency. We also estimate sensitivity level variable.

Aim To determine if younger and older hospital employed nurses have differences in their self-reported health, health related productivity quality of care. Background An understanding age cohort may assist nurse managers the potential care concerns staff. Method A cross-sectional survey design was utilised. There were 1171 usable surveys returned (47% response rate). Nurses over 50 made up 26% respondents. Result Older had a higher body mass index (BMI), mental well-being, pain scores, 12%...

In this study we propose an improved mean estimator for a sensitive variable under simple random sampling using Optional RRT models when measurement errors are present. We discuss two scrambling options and compare the square error (MSE) of proposed with some commonly used estimators. Both theoretical empirical results show superiority over existing Models evaluated both respect to efficiency respondent privacy.

Abstract Following Searls (1964), we propose an estimator for estimating the finite population variance. This is combination of Singh et al. (1973), and Prasad (1992) estimators has improvement over (1992), several other under certain conditions. Validity proposed examined by using seven numerical examples.

Sousa et al. and Gupta suggested ratio regression-type estimators of the mean a sensitive variable using nonsensitive auxiliary variable. This article proposes exponential-type one two variables to improve efficiency estimator based on randomized response technique. The expressions for squared errors (MSEs) bias, up first-order approximation, have been obtained. It is shown that proposed are more efficient than existing estimators. gain in over has also with simulation study by real data.

This study tested whether days on campus, financial access through a meal plan, and health consciousness were associated with number of meals that college students obtained from fast food restaurants.In April 2013, all currently enrolled in plan invited to participate an online survey (N = 1,246). Students asked report the total eaten past week where they them.Negative binomial regression was used, it found restaurants positively negatively consciousness. An association between campus not...

Social Desirability Bias (SDB) often leads to low response rate or worse, untruthful responding during face-to-face surveys involving sensitive questions. Randomized Response Technique (RRT) is used circumvent SDB by allowing respondents provide a scrambled response. However, if do not trust the RRT model, significant bias can still be introduced in estimates. Yet, none of quantitative models currently account for respondents' lack trust. We propose an Optional Enhanced Trust (OET) model...
