concept scale (KK. Scale). The total costs of treatment in the past year were estimated including all outpatient services used within the last year. Results: The costs of treatment amounted on average 31000 DM/year in the year before index admission and 43000 DM/year in the following year (including index admission). The costs were highly correlated with social disability (12) (p < 0.000 1) and moderately correlated with negative symptoms (t!, 12) (p < .05), but not with positive or general symptoms. Negative symptoms were highly correlated with social disability (t!, 12) (p < .01), positive and general symptoms only moderately (12) (p < .05). The t 1-12-correlation of the KK.S was pretty good with mean r = .4 in the 7 subscales. A negative correlation was found between drug confidence and the costs of treatment in the following year (p <
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
