This doctoral project investigates the potential for call data from
Lifeline - a generalist telephone counselling and referral service in
Australia - to be used as valid and reliable social indicators of
health. It presents a detailed descriptive summary and analysis of
Lifeline's national call data. The work presents a model of generalist
telephone counselling and referral use and a new indicator of social
need, which is proposed to reflect a community's capacity to provide
social support to some of its most socially isolated residents.
