Is headspace making a difference to young people’s lives?

Appendix B there are a number of areas with relatively high numbers of young people at risk of a disorder. This reflects the higher population numbers in each SA1 compared to other areas within the state. These results also indicate that small areas with high levels of mental health problems are often geographically clustered, which has implications for targeted service delivery. The difference between the proportion of young people within a region at risk of a disorder and the number of young people residing in that region requires further consideration in service allocation. This is of particular relevance in areas outside of the major cities which may have a high proportion of youth with mental health problems but small population size.

Appendix B Figure B17 Estimated prevalence and number of 12–17 years at risk of a mental health disorder in Inner Sydney Table B8 displays the estimated number of young people with mental health disorders who live within 10 and 30 km of an existing, or allocated, headspace centre. As outlined above, this analysis makes use of small area estimates of likely mental health burden based on YMM survey data. These data suggest that the current allocation of headspace services produces a high level of variability in service provision across states and between metropolitan and non-metropolitan areas. In particular, although small in overall population, the Northern Territory appears to receive a lower allocation of headspace centres relative to the needs of the youth population. This is due to both socio-demographic composition of the population and the number of young people who live in rural and remote areas, which both increase the likelihood of mental health disorders and increases the distance required to travel to obtain services. These results suggest that alternative models of allocation which are based on estimated population need and population dispersion may be required to achieve more equitable mental health resource allocation. It is important to note that the current model of centre expansion prioritises allocation to areas with high levels of socioeconomic disadvantage and rural and remote areas. As these variables are correlated with mental health risk, the current model does tend to allocate centres to areas with greater mental health service need, and therefore a model using mental health prevalence data, as specified above, is likely to make a modest difference in the allocation of most centres. A comparison of allocation based on the two methods is included in Figure B19 and Figure B20. Again, it is important to note that these small area estimates of mental health risk are not proposed as an optimal method of centre allocation. Rather, the inclusion of this example aims to provide an alternative weighting methodology, which may more closely reflect mental health service demand, for consideration by the Department. The figures provided here are not actual observed counts, but are estimates which are constrained by the available data, and should be interpreted accordingly. As outlined above, the geographic definition of access impacts on the interpretation of current population coverage and remaining need. Figure B18 displays SA1s within 10- and 30 km of an existing centre. It also includes the estimated population at risk of a mental health disorder for the same region. This figure indicates that those areas with higher at risk populations tend to fall outside of the 10 km definition of geographic access; however, they are likely to be considered to have access when the 30 km definition of access is applied. This highlights the importance of the definition of access applied to the interpretation of current coverage, and the potential disparities in service delivery.
