Ethics approval and consent to participate

: Ethics approval to conduct this study was approved by the research ethics boards at CAMH on May 15, 2014 (#026/2014) and at Simon Fraser University on August 28, 2015 (#2014 s0263).Prospective participants completed a brief telephone screen and if it appeared that they fulfilled inclusion criteria, they were invited to attend an in-person screen assessment. At this appointment, trained study assessors provided prospective participants with written and verbal information about the study and included time for individuals to ask questions. Prospective participants were then asked to sign the consent form, which was co-signed by the assessor. Consent forms are signed to acknowledge their understanding and agreement to participant in all aspects of the study and the ability to withdraw their consent at any time.In September 2015, the Principal Investigators (SM, AC) applied for and received an ethical amendment to the original approved application to recruit participants from the existing study to participate in a 2 year genetics sub-project. A separate consent procedure and consent form was developed for this sub-project.
