This study aims to analyse and compare social personal network and life satisfaction in family carers of demented and non-demented elderly. The sample comprises 99 participants: 52 care of a demented elderly and 47 of a non-demented one. Social personal network was studied by a questionnaire designed from Social Personal Network Analysis Instrument. Life satisfaction was evaluated by the Portuguese version of Satisfaction With Life Scale. Main findings suggest: both sub-samples have small and mainly primary social personal networks; technical support is the less represented function; life satisfaction is generally low for both sub-samples, nevertheless lower among those who care for a demented elderly; family carers of a demented elderly with smaller social personal networks are less satisfied with life. These results emphasize the importance of psychosocial interventions centred on the personal network, developing additional support sources.
