Procedure
Lesson 1 of the WCSC was provided to those randomized to this group immediately after randomization. Each subsequent lesson unlocked in succession, 24 h after lesson 1 with automated emails sent to inform participants of each lesson. Participants were encouraged to complete all 4 lessons within 4 weeks of receiving the content; however, they had access to the WCSC lessons for up to 8 weeks. At 8 weeks, the control group was given access to the WCSC. All participants received questionnaires at 4 weeks and 8 weeks post-randomization. If measures were not completed, they received up to 2 reminder emails and 1 phone call to encourage completion of the measures.
