The HILDA Survey Four Years On

What is the association between wealth and mental health?

“…In Wave 3 of the SoFIE study, 83% of the original sample members were re-interviewed,20 which, combined with the household response rate at Wave 1 of 77%, gives an estimated effective response rate of 64%. However, the attrition within the SoFIE study is low compared with other population-based longitudinal panel surveys 42 43. Selection bias might arise in our analyses if, on average across the strata of all variables included in the modelling, there was a different wealth–mental health association among those eligible but not included.…”

“…In wave 3 of the SoFIE study, 83% of the original sample members were re-interviewed [76], which combined with the household response rate at wave 1 of 77% gives an estimated effective response rate of 64%. However, the attrition within the SoFIE study is low compared with other population-based longitudinal panel surveys [77,78]. Selection bias might arise in our analyses if individuals drop out of the survey in a non-random manner (i.e., the more unhealthy may be more likely to decline to participate in follow-up years).…”

Data Survey: The HILDA Survey: Progress and Future Developments

“…As described in previous data survey articles in this journal (Wooden, Freidin and Watson 2002;Watson and Wooden 2004), the Household, Income and Labour Dynamics in Australia (HILDA) Survey is Australia's first and only large-scale, nationally representative household panel survey. Like all longitudinal surveys, the main purpose of the HILDA Survey is to identify changes in the behaviour of the sample units being observed (in this case, residents of a representative sample of private households) and, where possible, to quantify the magnitude of those changes.…”
