“…Studies that attempt to measure the amount of social capital in someone's life, for example, assume that the presence of social capital alone is positive (Kawachi, Kennedy, Lochner, & Prothrow-Stith, 1997;Kawachi, 1999;Lochner et al, 1999). Putnam (2000), Coleman (1990), Portes (2000), and others contend that social capital also can have a negative component, preventing individuals from accessing needed resources, depleting limited time and energy, and introducing destructive behaviors (Corcoran & Adams, 1997;Roschelle, 1997;Antonucci, Akiyama, & Lansford, 1998). Savage and Russell (2005), for example, studied homeless co-morbid women who suffered traumas, and found that a "small but definite" portion of the women's support networks also abused them, caused trauma, and facilitated their drug use.…”
