High congruence was found among the mortality of public mental health clients in eight states as indicated by multiple standardized measures of mortality. The higher risk of death among these clients compared with the general populations of their states using the AADRs and SMRs are consistent with conclusions of other research. Most importantly, the findings in this study show that results are similar in several states. In all eight states, public mental health clients have higher AADRs and higher relative risks of dying as shown by SMRs considering age and sex. Even though the magnitude of AADRs and SMRs vary by state and year, the results show strong similarities. CDC's National Vital Statistics Reports (11-18) and work by other researchers show differences in mortality and leading causes of death among state populations and years. Some interstate differences in mortality measures reported in this article might be attributed partially to differences among state populations. Therefore, in this study, mortality statistics were calculated and compared between mental health clients in each state and the general populations within the state during the same year.
