Summary
This study found that REDCap can be used for factorial design surveys (FDS) with a workaround. The "copy-and-hide" method proved feasible, offering quasi-automation and efficient labor-time for survey creation.
Area of Science:
- Health Informatics
- Survey Methodology
- Clinical Research Software
Background:
- Factorial design surveys (FDS) are valuable for complex research.
- REDCap is a widely used survey platform in research.
- REDCap's limitations in randomization and automation pose challenges for FDS implementation.
Purpose of the Study:
- To evaluate the feasibility of utilizing REDCap for creating factorial design surveys.
- To develop and assess a workaround for REDCap's lack of native randomization and automation in FDS.
Main Methods:
- A template survey was constructed with all necessary vignettes.
- A "copy-and-hide" workaround was implemented, duplicating the template for each survey instance and selectively hiding content.
- REDCap configuration time was recorded for a set of 42 surveys.
Main Results:
- The "copy-and-hide" workaround was successfully implemented, enabling the creation of factorial design surveys in REDCap.
- The configuration process for 42 surveys took approximately three hours.
- This approach provided a form of quasi-automation and demonstrated reasonable labor efficiency.
Conclusions:
- REDCap can be adapted as a platform for factorial design surveys through creative workarounds.
- The developed "copy-and-hide" method is a feasible and time-efficient strategy for implementing FDS in REDCap.
- Future enhancements may involve leveraging REDCap's Data Dictionary and integrating other survey software for improved functionality.

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Factorial Analysis is an experimental design that applies Analysis of Variance (ANOVA) statistical procedures to examine a change in a dependent variable due to more than one independent variable, also known as factors. Changes in worker productivity can be reasoned, for example, to be influenced by salary and other conditions, such as skill level. One way to test this hypothesis is by categorizing salary into three levels (low, moderate, and high) and skills sets into two levels (entry level...

01:27Introduction to Surveying, Plane Surveying and Geodetic Surveys

Surveying is the art and science of mapping the earth's surface. It involves measuring distances, angles in horizontal or vertical directions, and levels to understand the shape and size of land features. Surveying techniques are essential for various tasks, such as identifying the levels of a land area with reference to a specific point, and mapping undulations and water bodies.There are two main types of surveying: plane surveys and geodetic surveys. Plane surveys assume the earth is flat,...

Surveys are essential for marking property boundaries near water bodies. Different types of surveys are defined, each with its own function. Land surveys mark the property boundaries, while route surveys determine the position of properties on nearby highways. Topographic surveys create maps by capturing the three-dimensional features of the land. Hydrographic surveys focus on the shapes of underwater areas and the movement of streams through the properties. Mine surveys determine the relative...

01:28Survey Safety

Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

01:19Errors and Mistakes in Surveying
637
Errors and mistakes in surveying refer to inaccuracies in measurements and data recording. The errors are deviations from the actual value caused by human sensory limitations, equipment flaws, or environmental effects. These errors are typically unintentional and can result from the inherent imperfections in the instruments used, atmospheric conditions, or the observer’s inability to perceive exact measurements. On the other hand, mistakes are caused by the surveyor's lack of...
