Abstract The current investigation is a planned, systematic study of dignity as critical to understanding the experience of homelessness and improving services and programs for the homeless. Specifically, we conducted a thematic content analysis of interviews with 24 homeless men and women to identify their perception of specific environmental events that validate and invalidate dignity. In addition, we explored the impact that these events have on homeless persons. Eight types of events were identified that sustain dignity such as being cared for by staff and having resources available to meet basic needs. Eight types of events were found that undermine dignity, such as being yelled at or insulted by staff persons and having staff use rules in an excessive and arbitrary way. Two outcomes followed the sustenance of dignity including increased self-worth and motivation to exit homelessness. Three outcomes followed the undermining of dignity including anger, depression, and feelings of worthlessness. The results suggest that dignity is an important variable to consider in understanding the experience of homelessness. Policies and programs that support validating the dignity of homeless persons are encouraged. (Authors)
