A chart to illustrate the score distribution of CISS
See chart above: The green bars indicate the CISS score distribution of outpatient drug users who were mostly maintained on methadone (e.g., 32 subjects scored 9, the mode score).
Brief description
This group consisted of 243 drug users (160 male, 83 female) who accounted for 96% of all clients appearing on the register of the Royal Free drug service.
Their mean age was 37.0 years (sd = 7.9, range = 17 - 56).
Their mean period since treatment entry was 872.3 days (sd = 774.1, range = 0 - 3124).
Most were poly-drug users, 96% were primarily opiate users and 90% were being prescribed opioids (methadone) by the service.
CISS total scores were normally distributed, the mean was centrally located and there was no floor or ceiling effect.
One standard deviation either side of the mean indicated a score range of 6 to 12 as being of average problem severity for this type of sample.
