groups.<br />
The age and sex distributions below illustrate the closeness of the groups after undertaking<br />
propensity score matching. The majority of age groupings are closely aligned between the<br />
<strong>headspace</strong> treatment group and the matched no and other treatment groups. An exception are those<br />
aged 18-19 years. A higher representation of 18-19 year olds is present in the <strong>headspace</strong> treatment<br />
group when compared <strong>to</strong> the other matched treatment groups (17% compared <strong>to</strong> 12%). This<br />
<strong>difference</strong> is statistically significant.<br />
Alignment of the proportion of males and females between the groups is very precise after<br />
propensity score matching. It is recognised that the <strong>headspace</strong> treatment survey data has a<br />
greater representation of females when compared <strong>to</strong> the overall representation in the <strong>headspace</strong><br />
administrative data (80% compare <strong>to</strong> 63%). This needs <strong>to</strong> be taken in<strong>to</strong> account when seeking <strong>to</strong><br />
generalise the results <strong>to</strong> the entire <strong>headspace</strong> clientele.<br />

As with other methods, PSM methods are also limited by an inability <strong>to</strong> account for unobserved<br />
<strong>difference</strong>s between <strong>headspace</strong> clients and others with similar observed characteristics but who<br />
remain outside the <strong>headspace</strong> program. The PSM does improve <strong>to</strong> an extent, the identification of<br />
<strong>headspace</strong> effectiveness relative <strong>to</strong> matched comparison groups.<br />
Interviews with <strong>headspace</strong> clients and staff<br />
Sample and recruitment<br />
Qualitative interviews were conducted between April and June 2013 with 50 <strong>young</strong> people who were<br />
receiving <strong>headspace</strong> services, and 25 <strong>headspace</strong> staff from 5 of the 40 operational <strong>headspace</strong><br />
centres around Australia (that is, 5 <strong>headspace</strong> staff and 10 <strong>young</strong> people per site).<br />
The fieldwork sites are not a representative sample of <strong>headspace</strong> locations around Australia. Site<br />
selection was based on a range of primary and secondary fac<strong>to</strong>rs as outlined below. The primary<br />
fac<strong>to</strong>rs focus on diversity, while the secondary fac<strong>to</strong>rs aim <strong>to</strong> minimise the burden on participant sites<br />
