Application of a social capital scale in older women attending public primary care clinics (r = -0,43, p < 0,01). Higher territorial roots were associated with a lower perception of social community resource availability (r = -0,42, p < 0,01). Conclusions: The social capital scores in these women were low. Their better support networks were close relationships and relatives. The sensation of solitude increased with age. (Rev Med Chile 2016; 144: 972-979)
