WHOQOL-BREF and ASI domain scoring is a useful tool in measuring overall quality of life and levels of addiction among OST participants .
BACKGROUND Opioid substitution treatment ( OST ) can increase quality of life ( WHOQOL-BREF ) and reduce addiction severity index ( ASI ) scores among participants over time .
OST program participants have noted that improvement in quality of life is one of the most important variables to their reduction in drug use .
However , there is little systematic underst and ing of WHOQOL-BREF and ASI domain changes among OST participants in low and middle-income countries ( LMIC ) .
Staff attitudes and retention of patients in methadone maintenance programs.
A study was made of the effect of staff commitment to abstinence-oriented policies on retention of  patients in methadone maintenance . Staff working in six public methadone programs in Sydney , Australia , were surveyed in 1989 and 1992 using the  Abstinence Orientation Scale . The association of the clinics ' median Abstinence Orientation scores with the time in treatment of a r and om sample of their 1988 - 1989 admissions was summarised using Cox regression . Patients ' risk of discharge increased by a factor of three with every one unit increase in the clinics ' median Abstinence Orientation scores , ( RR 3.4 , 95 % CI 2.3 - 5.0 ) . Abstinence-oriented policies were shown to disadvantage ex-prisoners
