Understanding attrition in the LSAC
Jul 26, 09:00
Growing Up in Australia: The Longitudinal Study of Australian Children (LSAC) was designed to provide data that enables a comprehensive understanding of children’s development within Australia’s current social, economic and cultural environment. Since 2004, two cohorts of 5,000 children and their families have been interviewed every two years. The “Baby” and “Kinder” cohorts will be interviewed for the eighth time in 2018 and will be aged 14-15 and 18-19 respectively. Response rate have declined gradually over the waves, however Wave 7 saw a significant drop in response for both cohorts. In addition, the study faces new challenges in retaining respondents as the children move into young adulthood.
This paper will present the pattern of attrition over the life of the study, as well as findings from analyses of the individual and family characteristics that impact on attrition (e.g., age, educational level). Interview process data, such as timing of first contact, number of call attempts, extent of contact with interviewer, can provide further insight and provide a more comprehensive picture of the factors that impact on study participation. This paper considers the extent this data can inform the evaluation, monitoring and management of interview processes in the LSAC context, with the view to improve participation rates.
