Validating multiple

While mental comorbidity is considered common in multiple sclerosis (MS), its impact is poorly defined; methods are needed to support studies of mental comorbidity.

We validated and applied administrative case definitions for any mental comorbidities in MS.

Using administrative health data we identified persons with MS and a matched general population cohort.

Administrative case definitions for any mental comorbidity, any mood disorder, depression, anxiety, bipolar disorder and schizophrenia were developed and validated against medical records using a a kappa statistic (k). Administrative data are a valid means of surveillance of mental comorbidity in MS.

Administrative data have the advantage that they are recorded during an episode and need not be recalled later.

Administrative data, however, are collected for health system management and are often inadequately validated [].

Indeed, few published case definitions for mental comorbidity have been validated, and efforts to develop and validate case definitions for depression have identified poor concordance with the CIDI Short Form [].

We aimed to validate administrative case definitions for several mental comorbidities in MS, and to describe their prevalence among persons with MS versus a matched cohort from the general population.

We hypothesized that the prevalence of depression, anxiety, bipolar disorder and schizophrenia would be higher in the MS population than in the general population.].

Since 1984, MH has maintained computerized records of health services claims, which can be linked using a unique personal health identification number (PHIN) identifying the person who received the service.
