Should you use Likert or VAS for EMA research?
In a new paper led by @jmbh.bsky.social & Alberto Jover, we assigned n~160 in a 2 week study to either
📏1-7 Likert or
🎚️1-100 Visual Analogue Scale
and compared results using Bayesian multilevel models.
Brief thread with results.🧵

1/ VAS (compared to Likert) showed - higher within-person means - higher lag-0/1 correlations - lower within-person skew & response frequencies of exact 0s. Most effects weak. Detailed plots per item & category available in the paper, I'll show the means as an example:

Interesting study! Did you take a look at careless responding and response tendencies? It might be harder to do things like straightlining in VAS than in likert. I have to say this changed my understanding of the topic, since I was tought there isn't much of a difference. Are there moderators?

We developed a non-evaluative personality inventory using ideas like these. Unfortunately haven't followed up. www.researchgate.net/profile/Erik...
