Descriptive regression models were used to examine whether client characteristics or support experience in the defining period were associated with receipt of SHS support in the prospective study period (ongoing service use). Information on interpreting regression models is in the section Understanding factors associated with past and future support. Two models were created; a ‘client characteristic’ model (Model 1) that contained client characteristics and a ‘reasons’ model (Model 2) that supplemented these characteristics with flags for the 26 possible reasons why the client sought support during the defining study period.
Variations in state and territory specific policies and service delivery models mean that the likelihood of a client receiving services in the future varies among states and territories. Therefore, in addition to a national model, separate regression models were created for each state or territory where there was sufficient sample size (at least 3,500 clients; Figure CPO.7). The models are descriptive, that is, they are intended to describe the client variables that are associated with past or future service use without proposing or testing specific causal pathways.
The outcome variable (receipt of SHS support) was a binary measure (yes or no) and did not distinguish between clients that needed SHS services only once in the prospective study period and clients that required frequent support.
Risk ratios were created to measure the association between the use of SHS services and a set of client characteristics (see Glossary on Relative Risk for how to interpret the results).
Some bias is present in this outcome measure because some clients who required services in the future may not have been able to receive them (see the section on Bias within the SHSC longitudinal data).
The results from the client characteristic model (Model 1) demonstrates having a mental health issue in the study period had the greatest association with future SHS support (Figure CPO.7). Nationally, children that had mental health issues were 79% more likely to receive SHS support into the future.
Being an Indigenous Australian also had a strong association with future support (48% greater likelihood in the national model). This may be in part due to the social and economic disadvantages faced by Indigenous Australians and a higher prevalence of health risk factors (POA 2004, AIHW 2020).
Other factors associated with an increased likelihood of ongoing SHS support include, having experienced FDV (39% more likely) or experiencing homelessness (34%). Transitioning from custody in at least one support period (28%), presenting after leaving care (20%) and having problematic drug or alcohol issues (17%) were also associated with ongoing SHS support.
The reasons model (Model 2) demonstrates that having domestic and family violence as a reason for seeking assistance was associated with an increased likelihood of ongoing SHS support (34% greater likelihood in the national data). Financial difficulties as a reason for seeking assistance was also associated with ongoing support (33% greater likelihood).
