This qualitative study examined the process families use to care for a depressed and suicidal family member at home. The grounded theory method was used for data collection and analysis. Seventeen family members were interviewed. The data revealed the basic social process of Maintaining Vigilance Through Managing, which depicts an ongoing, cyclical process that begins at a point of not knowing. Family members then move on to identifying, then gaining awareness, followed by knowing or understanding. This allows them to take action, then to proceed to watching and waiting. They then return to gaining awareness armed with new knowledge or understanding. It is at this point that the process becomes cyclical. It varies in intensity over time, depending on the level of depression and the risk for suicide. To preserve the integrity of these families, nurses must help develop strategies to guide them through this process as they care for their depressed and suicidal loved one.
