Preregistration of Investigations for the 2019 SSC Survey

This post is about the 2019 SSC Survey. If you’ve read at least one blog post here before, please take the surveyif you haven’t already. Please don’t read on until you’ve taken it, since this post could bias your results.

1. Can we confirm or disconfirm different corn-eating profiles of algebraists vs. analysts?

2. Can we replicate the study showing that people who eat more beef jerky are more likely to be hospitalized for bipolar mania?

3. Are there differences in side effects among SSRIs? (to be limited to people taking an SSRI one month or more, will be looked at both effect by effect, and with a lumped-together side effect index where each mild effect counts as 1 point and each severe effect as 3 points)

4. Is there a difference in people’s efficacy ratings for SSRIs (SSRI Effectiveness, SSRI Overall) depending on whether the person was taking the SSRI for depression vs. for anxiety?

5. What percent of people coming off SSRIs experience discontinuation symptoms? Are there differences among different agents? (main analysis to be limited to people who were taking an SSRI at least a few months, discontinued with a gradual taper lasting at least a few weeks, and were not cross-tapering onto any other psychiatric medication).
