Psychological Distress in Australian Onshore and Offshore Immigration Detention Centres from 2014-2018

This study examines the impact of length of detention and location of detention on psychological distress amongst Australian immigration detainees. This study employs a repeated measures cross-sectional study, utilising Australian government data from 2014 to 2018 that relied on the Kessler-10 (K10) to measure psychological distress. There were 21,703 assessments conducted which included 15,264 assessment onshore over a 5 year period and 6439 assessments offshore over a 3 year period. The mean overall K10 score onshore was 18.85, while offshore it was 24.37. K10 scores increased with length of time detained both onshore and offshore, with K10 scores offshore generally higher at each time point. The results of this study add to a growing body of evidence that suggests that length of time detained and particularly offshore detention has a substantial impact on mental health.
