Effective therapeutic interventions for Australian adolescents using alcohol and/or other drugs: a scoping review

Duration of stay and rate of subsequent criminal conviction and hospitalisation for substance use among young people admitted to a short-term residential program

INTRODUCTION

This study examined the association between program duration and rate of criminal conviction and hospitalisation for substance use up to 15 years later among young people admitted to a short-term residential program for drug and alcohol use.

METHODS

Data were derived from linked administrative records of all clients referred to a modified therapeutic community for young people from January 2001 to December 2016 in New South Wales, Australia (n = 3059). Cox proportional hazards regression analyses examined the rate of conviction (separately for any offence, violent offence, non-violent offence and administrative offence) and hospitalisation for substance use, up to 15 years post-program among young people who attended treatment for 1-29 days, 30-59 days, 60-89 days and 90-120 days.

RESULTS

Thirty days or more in treatment was independently associated with a lower rate of conviction for any offence and a non-violent offence, as well as hospitalisation for substance use, while 60 days or more was associated with a lower rate of conviction for a violent and administrative offence, relative to those who spent 1-29 days in the program. Additional months in the program were also associated with reduced rates of conviction and hospitalisation, although 90-120 days appeared to confer no additional benefits than 60-89 days.

DISCUSSION AND CONCLUSIONS

At least 60 days may be the minimum duration needed for short-term, therapeutic community programs to reduce the risk of conviction across all crime types and hospitalisation for substance use.

Hospitalisation following therapeutic community drug and alcohol treatment for young people with and without a history of criminal conviction

INTRODUCTION

This study examines the association between treatment in a therapeutic community for adolescents with drug and alcohol problems on hospitalisation outcomes up to 15 years later for all clients, and separately for those with and without a history of criminal conviction.

METHOD

A quasi-experimental design was used to examine the linked administrative health and criminal justice records for all adolescents admitted to the Program for Adolescent Life Management (PALM) from January 2001 to December 2016 (n = 3059) in Sydney, Australia. ICD-10AM codes were used to designate hospitalisation outcomes as either physical injury, mental health problems, substance use disorders, or organic illness. The treatment and comparison groups were matched on factors associated with program retention, resulting in a final sample of 1266 clients. We examined the rate of hospitalisation up to 15 years posttreatment for all clients and stratified by prior conviction status using Cox regression analyses.

RESULTS

The treatment group had significantly lower rates of hospitalisation for a physical injury (HR = 0.77 [95% CI = 0.61-0.98]), mental health problem (HR = 0.62 [95% CI = 0.47-0.81]), substance use disorder (HR = 0.59 [95% CI = 0.47-0.75]), and organic illness (HR = 0.71 [95% CI = 0.55-0.92]). There was a significant interaction between treatment and prior criminal conviction status on rate of hospitalisation for physical injury, suggesting that the effect of treatment on physical injury was significantly greater for clients with a prior criminal conviction.

CONCLUSIONS

Adolescents who engage in a therapeutic community treatment program may have a long-lasting reduction in the risk of subsequent hospitalisation. This also appears to apply to those with a history of criminal conviction.
