Split Questionnaire Design for Massive Surveys

Design and Estimation for Split Questionnaire Surveys

Guide to the design and application of online questionnaire surveys

Collecting research data through traditional approaches (face-to-face, postal or telephone survey) can be costly and time consuming. The emerging data collection approach based on internet/e-based technologies (e.g. online platforms and email), is a relatively cost effective survey alternative. These novel data collection strategies can collect large amounts of data from participants in a short...

Massive Variability Surveys from Venezuela

At the Venezuela National Astronomical Observatory we are carrying out variability surveys spanning many hundreds of square degrees near the celestial equator, using an 8k x 8k CCD Mosaic Camera optimized for drift-scanning on a 1m Schmidt telescope. Among the initial efforts was a project to obtain the first moderately deep, homogeneous sample of young stars over an area of ∼ 180sqr.deg. encom...

Design and trial of a new questionnaire for occupational health surveys in companies.

In this article we present an example of our method for instrument development. This method is called the Development Cycle. It consists of four main stages: (1) defining the requirements for an instrument; (2) research, design and pilot testing; (3) implementation and (4) evaluation. An application of the Development Cycle was realized within a project for the development of a basic questionna...

Assessing reliability and validity of the Work Design Questionnaire as a tool for macro ergonomics surveys: A case study in an Iranian worker population in 2016

Background: The imbalance between job demand and controls is associated with physical and mental disorders. The Work Design Questionnaire (WDQ) is one of the newest tools for macro-ergonomics evaluation of organizations and workplaces. In this research, the reliability and validity of the Persian WDQ (PWDQ) in the evaluation of occupational accident management and safety promotion in Persian-la...
