Young children who stay with their families in homeless shelters face chronic challenges related to extreme poverty and acute risks from stressful events surrounding the loss of housing and move to shelter. These adversities increase the likelihood of a range of poor developmental outcomes. Consistent with the risk and resilience perspective, however, many children who experience family homelessness succeed, functioning as well or better than their non-homeless peers. As such, efforts to support resilience should consider how best to enhance protective factors, such as supportive environments within shelter settings. With data from 60 caregivers of children ages birth to 5years recruited from family shelters, we assessed caregivers' perceptions of community support as well as child and family well-being in terms of recent adverse experiences, parenting stress, access to social support, and child social-emotional functioning. Many caregivers experiencing family homelessness perceived negative aspects of the shelters where they were staying with their children. Furthermore, children whose caregivers had more negative perceptions of the shelter environment displayed worse social-emotional functioning, even when accounting for differences in parenting stress, recent family adversity, and other sources of social support. Because young children rely on their caregivers as primary resources for nurturance and support, we encourage family homelessness service providers to work in partnership with caregivers to create more inclusive and empowering practices within the shelter context. Doing so is likely to improve children's developmental outcomes and the overall well-being of the families.
