The long and short of it: The impact of Apprehended Domestic Violence Order duration on offending and breaches

By Adam Teperski and Stewart Boiteux

AIM To examine whether longer apprehended domestic violence orders (ADVO) are associated with changes in domestic violence (DV) offending and ADVO breaches. METHOD A dataset of 13,717 defendants who were placed on an ADVO after a DV incident between January 2016 and April 2018 was extracted from the NSW Bureau of Crime and Statistics and Research’s ADVO database. This included 10,820 defendants subject to a final 12-month order, and 2,897 defendants subject to a final 24-month order. We utilised an entropy balancing matching approach to ensure groups of defendants subjected to differing ADVO lengths were comparable and implemented an event study analysis to examine quarterly differences in offending outcomes in the three years after the start of the order. In doing so, we were able to examine relative differences in offending in the first 12 months (where both groups were subject to an ADVO), the second 12 months (where only the 24-month ADVO group were subject to an ADVO), and the third 12 months (where neither group were subject to an ADVO). RESULTS In the 12 to 24 month period, where ADVOs with a longer duration were active and shorter ADVOs were not, longer ADVOs were associated with increased breach offending and decreased DV offending. Specifically, in the 5th, 6th and 7th quarters after the beginning of a final order we observed 3.4 percentage points (p.p.), 4.1 p.p., and 2.3 p.p. increases in defendants breaching their ADVO, respectively. When considering baseline rates of breaching, this represents relative increases of 79% to 161%. In the 5th, 6th, and 7th quarters after the beginning of a finalised order, longer ADVOs were associated with respective 1.8 p.p., 2.0 p.p., and 3.1 p.p. decreases in DV offending, reflecting relative decreases in DV offending by 41% to 59%. We find no group differences in DV offending or breaches in the subsequent 12 months, when ADVOs for both groups had expired. While the study examined multiple factors related to both longer ADVO length and offending, we cannot exclude the possibility that unobserved factors may be influencing our results. CONCLUSION Relative to 12-month ADVOs, 24-month ADVOs were associated with an increase in the probability that an offender breaches the conditions of their ADVO, and a decrease in the probability that an offender commits a proven DV offence.
