14.1 Registered Report Example

Barrett et al., in prep

What access did you ALREADY have to the data?

How will you test your hypotheses? What will you take as evidence of support?

Being specific in defining ROIs/COIs etc. is essential! (and difficult)

Contingency plans - “what happens when…”

14.2 Exploratory Analyses?

Can be discussed at Stage 1 where they are necessary to justify study variables or procedures that are included in the design exclusively for exploratory analysis.

14.3 Things you can do now

• Create an OSF account/profile if you don’t already have one
• Create an OSF project for your ABCD study
• Choose a template and start drafting a pre-registration
• Start drafting a registered report
