Recent research on informal support in senior housing has suggested that frail tenants receive limited assistance from their neighbors. Far less attention has been directed at understanding the role of healthy, independent tenants as neighborly helpers. Informal neighborly assistance among tenants in a congregate housing facility was examined to identify the types of helping behavior which occurred among tenants. In-depth, open-ended interviews with 24 tenants revealed four patterns of assistance: (1) high helpers; (2) activity helpers; (3) reciprocal helpers; and (4) non-helpers. High helpers saw themselves as helping many tenants in the complex. Activity helpers helped their neighbors by performing various activities. All activity helpers reported that their assistance was sporadic. Reciprocal helpers limited their involvement to one or two special friends. Non-helpers were respondents who had recently moved into the complex, who reported health problems which interfered with their helping, and who reported that they had never been asked to help or that their efforts to help had been rebuffed. Housing managers should be aware of the important role that activities may play in providing opportunities for helping. (NB)
