Update on data archiving (6)
– Four-year panel dataset comprising 2,539 respondents who participated in all four waves of the OCJS.
– Includes derived offending, ASB and drug use variables, derived risk factor variables and original survey variables. Also five cluster variables derived as a result of latent class analysis.
– Paired transitions dataset used in the analysis of 12-month transitions between consecutive OCJS interviews.
