Participant timeline. Potential participants will be assessed for eligibility through an initial assessment of depressive symptoms. The initial assessment phase consists of administration of the PHQ-9 and a short screening telephone interview. Subsequent assessments consist of all the instruments presented in the Outcome measures section. After the initial assessment, the participants meeting inclusion criteria will be randomly assigned to one of the two conditions: immediate online intervention condition (Group 1) or the delayed-intervention condition (wait-list) (Group 2).
