Assessment details for primary and secondary outcome measures

Measure	Domain	Self-report or objective	Groups Assessed	Assessment Points/Windows
Primary Outcomes
MATRICx motivators	Collaboration readiness	Self-report	Both	Baseline, EOT, 6 M, 12 M
MATRICx barriers	Collaboration readiness	Self-report	Both	Baseline, EOT, 6 M, 12 M
Transdisciplinary orientation (TOS)
Coauthor network size	Collaboration behavior	Objective (bibliometric)	Both	Pre (−21 – −4 months before EOT) and post (4–21 months after EOT)
Secondary Outcomes
IL Team/proposal formation	Process measure	Self-report	IL only	EOT
IL Pilot fund request	Process measure	Objective	IL only	∼ 6 M
IL feedback	Intervention feedback	Self-report	IL only	EOT, 6 M, 12 M
Collaboration self-efficacy	Collaboration readiness	Self-report	Both	Baseline, EOT, 6 M, 12 M
Grant submissions	Collaboration behavior	Self-report	Both	Baseline, EOT, 6 M, 12 M

6 M = 6-month follow-up; 12 M = 12-month follow-up; EOT = end of treatment; IL = Innovation Lab; MATRICx=Motivation Assessment for Team Readiness, Integration, and Collaboration; TOS = Transdisciplinary Orientation (TDO) Scale.

Collaboration self-efficacy was added after Cohort 1 completed EOT; thus, only the 2018 cohort data are presented, and the measure is considered secondary. Team/proposal formation and pilot fund request were not pre-registered, but they have been added to address comments from an anonymous reviewer.
