  1. aThe Index of Relative Socioeconomic Disadvantage (IRSD) is a summary measure of economic and social conditions within a particular area/postcode (e.g., employment, fluency in English and household size). It is taken from the Census of Population and Housing: Socio-Economic Indexes for Areas (SEIFA), Cat no. 2039.0.55.001: Australian Bureau of Statistics; 2001. A low score is indicative of greater socioeconomic disadvantage
  2. bMeasures for occupation and education are from the Australian Standard Classification of Occupations (ASCO), Cat. No. 1220.0, Australian Bureau of Statistics 1997 and the Australian Standard Classification of Education (ASCED), Cat. No. 1272.0, Australian Bureau of Statistics 2001
  3. cMeasures for full-time (usually working at least 35 h per week) and part-time (usually working 1–35 h per week) are from the Australian Health Survey: Users' Guide, 2011–13, Cat. No. 4363.0.55.001, Australian Bureau of Statistics [45]
  4. dPre-injury job satisfaction is based on the stem question from the Measure of Job Satisfaction questionnaire by Traynor, M. and Wade, B. 1993
  5. eRecovery 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
  6. fCategories of income are from the Household, Income and Labour Dynamics in Australia (HILDA) Survey Wave 6 Household Questionnaire. Adjusted household income divides household income by the sum of points: 1 for the first person ≥15 years; 0.5 for each additional person ≥15 years; and 0.3 for each person <15 years. This is taken from the National Health Survey: Users’ Guide, Cat.no. 4363.0.55.001. Australian Bureau of Statistics 2004–05
  7. gBMI classification is from the Global Database on Body Mass Index, World Health Organisation
  8. hQuestions are from the Alcohol Use Disorders Identification Test: Self-Report Version (AUDIT-C) from the Drink-less program, The University of Sydney. http://sydney.edu.au/medicine/addiction/drinkless/resources.php
  9. i1 standard drink contains 12.5 ml or 10 g of alcohol according to the National Health and Medical Research Council (NHMRC), Australian Alcohol Guidelines Health Risks and Benefits, October 2001
  10. jRisk of long and/or short term harm due to alcohol consumption was assessed with the National Health and Medical Research Council (NHMRC) levels
  11. kSelf-assessed pre-injury health status is based on Question 1 from the Short Form 36, Version 2.0, (SF36v2)
