I am currently working on my dissertation and would like input on the best platform to use for a study that includes data collection at two points in time and is not cost prohibitive. What platform would you recommend?
An electronically distributed/collected approach is by far the most economic method for data collection (once you're past any cost outlays for the software, of course) .
The two concerns you'll need to address are:
1. If your aim is to match scores by respondent across the two occasions, you'll need some sort of identification information. This often makes getting approval from IRB committees tougher, as you're departing from anonymized measures.
2. If your query is really about, which online survey platform should I use, then have a look at this comparison summary: https://www.pcmag.com/picks/the-best-online-survey-tools
David Morse makes a great point about the use of electronic platforms--I am a heavy user of Qualtrics both in my evaluation work and my academic work.
I would like to add something about the identification method: you can have them use the first initial of their first or last name and the last four digits of their phone numbers as an identification number. This way, you're not collecting their full name or phone numbers and you're still getting a unique identifier. I've used this for multiple data collection efforts with very little resistance from IRB.
It is being suggested that quantitative research is the most accurate and meaningful for analysis. Thus surveys are common forms of quantitative data collection that could be created and completed online whilst it is convenient, accessible, and in most cases with wider coverage
Platforms applications for collecting data are:
KoboToolbox, team scope open data kit google form, and web forms which are linked to a database, making secure your data from unauthorized multilation.
