This study aims to identify relationships between the level of powerlessness and social support for the elderly women. The participants were 205 community-dwellers who aged over 60 years. Data were collected by the face-to-face interview from summer 2001. Scores for powerlessness and social support were 66.4 out of 95 and 45.3 out of 80, respectively. The social support showed significant relations with both emotional and self-esteem support in the powerlessness. Furthermore, it was found that social support including emotional support had been the most important factor to influence on powerlessness. The findings suggested that those with social support may be more likely to have a psychosocial wellbeing in elderly women. Thus, it is necessary to assess their social support network in the context of their family, as this is a factor strongly linked to the powerlessness.
