Introduction: Smoking prevalence remains high among people with a mental illness, contributing to higher levels of morbidity and mortality. Health and community services are an opportune setting for the provision of smoking cessation care. Although family carers are acknowledged to play a critical role in supporting the care and assistance provided by such services to people with a mental illness, their expectations regarding the delivery of smoking cessation care have not been examined.Aims: To explore family carer expectations of smoking cessation care provision by four types of health services, to clients with a mental illness, and factors associated with expectations.Methods: A cross-sectional survey was conducted with carers of a person with a mental illness residing in New South Wales, Australia. Carers were surveyed regarding their expectations of smoking cessation care provision from four types of health services. Possible associations between carer expectation of smoking cessation care provision and socio-demographic and attitudinal variables were explored.Results: Of 144 carers, the majority of carers considered that smoking cessation care should be provided by: mental health hospitals (71.4%), community mental health services (78.0%), general practice (82.7%), and non-government organisations (56.6%). The factor most consistently related to expectation of care was a belief that smoking cessation could positively impact mental health.Conclusions: The majority of carers expected smoking cessation treatment to be provided by all services catering for people with a mental illness, reinforcing the appropriateness for such services to provide smoking cessation care for clients in an effective and systematic manner.
