 Participant drop-out: Consistent with an intention-to-treat approach, participants who drop out will be asked to continue to participate in the study assessments. To assess participant adherence, we will measure the number of times participants access the self-help manual website and the number of minutes they spend on each module. The number of eligible individuals who: decline to participate, are randomized, begin the study, or drop out of the study and the week at which this occurs will be recorded.
