  1. aParticipation status ‘yes’ was measured using the information recorded in variables - work status at six, 12 and 24 months and the SF36, Physical Component Score (PCS) at six, 12 and 24 months respectively
  2. ** P < 0.01, *P < 0.05, NS not significant
  3. bThe measure for occupation is from the Australian Standard Classification of Occupations (ASCO), Cat. No. 1220.0, Australian Bureau of Statistics 1997. See Table 1, Occupational skill level for all categories
  4. cCategories of income are from the Household, Income and Labour Dynamics in Australia (HILDA) Survey Wave 6 Household Questionnaire. Income is before tax (AUD) and excluding number of people in household
  5. dRecovery expectations was based on two measures from a large Canadian study of injured workers with soft tissue injuries by Cole et al. (2002) due to the lack of validated measures
