RSVs were carefully trained to monitor dyads' reactions. If either member of the dyad reacted in a persistently negative manner to the intervention, the activity was discontinued. RSVs were taught to look for depression in the following ways: look for a saddened face, crying, shaky voice, statement from the caregiver that the care recipient seems depressed (e.g., downtrodden, sad, blue). The LIFE Volunteer Interventionist Manual includes "Feelings Checks" in which the RSVs ask, "How does talking about these memories make you feel?" The average treatment fidelity score achieved by RSVs during training was 89.8%.
