This was more <strong>of</strong> a problem forstudies set up as cross-sectional analyses, although even with longitudinal studies itwas still difficult to adequately control for factors that influence both and can changeover time, such as socioeconomic factors.Second, some outcomes cannot be easily converted into economic costs. Forexample, literature generally examined outcomes associated with reaching interimliteracy and numeracy standards, rather than completion <strong>of</strong> Year 12 (which can in turnbe linked to later income), or indeed to adult employment, labour force participation orearnings.Finally, different and inconsistent measures <strong>of</strong> FF and <strong>of</strong> outcomes have been appliedin past studies. The application <strong>of</strong> findings would thus result in somewhat <strong>of</strong> a mosaic<strong>of</strong> varying and overlapping definitional interpretations.Interestingly, high level trends are evident from the literature. Health outcomes appear to be most dependent on issues such as family attachment,joint family time and role modelling. These characteristics have been described mostfrequently in the literature as underlying substance abuse and psychological outcomesin children.24
