Combining multiple measures into a summary index ‐ a step toward more reliable measurement

The objective of the application of the Balanced Scorecard methodology in the Veterinary and supplies PA`LANTE S.P.R. OF R.L. DE C.V. In the area of production and repair of trailers is to identify exactly what should be monitored to introduce a reliable measurement strategy that provide information on performance and understand why they are giving certain results, the methodology is to align the companies towards the achievement of business strategies, through tangible objectives and indicators as it converts the vision of companies into action through a coherent set of indicators grouped into four business perspectives that are: Financial, Clients, Internal Processes and Training and Growth since this methodology suggests that these perspectives cover all the processes necessary for the proper functioning of a company. The contribution of the methodology is to determine what factors are influencing the area of production and repair of trailer that are affecting the production times considering the last three quarters of the year 2018.

Abstract Purpose To assess the test–retest reliability of the EQ-5D-5L and the reworded Quality of Life After Traumatic Brain Injury Overall Scale (QOLIBRI-OS) for the general population of Italy, the Netherlands, and the United Kingdom (UK). Methods The sample contains 1864 members of the general population (aged 18–75 years) of Italy, the Netherlands, and the UK who completed a web-based questionnaire at two consecutive time points. The survey included items on gender, age, level of education, occupational status, household annual income, chronic health status, and the EQ-5D-5L and reworded QOLIBRI-OS instrument. Test–retest reliability of the EQ-5D-5L dimensions, EQ-5D-5L summary index, EQ VAS, reworded QOLIBRI-OS dimensions and reworded QOLIBRI-OS level sum score was examined by Gwet’s Agreement Coefficient (Gwet’s AC) and Intraclass Correlation Coefficient (ICC). Results Gwet’s AC ranged from 0.64 to 0.97 for EQ-5D-5L dimensions. The ICC ranged from 0.73 to 0.84 for the EQ-5D-5L summary index and 0.61 to 0.68 for EQ VAS in the three countries. Gwet’s AC ranged from 0.35 to 0.55 for reworded QOLIBRI-OS dimensions in the three countries. The ICC ranged from 0.69 to 0.77 for reworded QOLIBRI-OS level sum score. Conclusion Test–retest reliability of the EQ-5D-5L administered via a web-based questionnaire was substantial to almost perfect for the EQ-5D-5L dimensions, good for EQ-5D-5L summary index, and moderate for the EQ VAS. However, test–retest reliability was less satisfactory for the reworded QOLIBRI-OS. This indicates that the web-based EQ-5D-5L is a reliable instrument for the general population, but further research of the reworded QOLIBRI-OS is required.

Reliable Measurement

A 19F solvatomagnetic comparison of 4-fluorophenol and 4-fluoroanisole yields a more reliable measurement of the hydrogen-bond acceptance of ionic liquids and green solvents than the solvatochromic comparison method.

The Relationship

Researchers often want to examine the relationship between a variable of interest and multiple related outcomes. To avoid problems of inference that arise from testing multiple hypotheses, one can create a summary index of the outcomes. Summary indices facilitate generalizing findings and can be more powerful than individual tests. In this article, we introduce a command, swindex, that implements the generalized least-squares method of index construction proposed by Anderson (2008, Journal of the American Statistical Association 103: 1481–1495). We describe the command and its options and provide an example based on Blattman, Fiala, and Martinez’s (2014, Quarterly Journal of Economics 129: 697–752) evaluation of a cash transfer program in Uganda.
