Adequacy of Medical Treatment Among Older Persons With Schizophrenia

This study used Krause's model of illness behavior in later life to examine factors associated with adequacy of medical treatment in a racially diverse sample of older patients (age 55 and over) with schizophrenia. In a cross-sectional community study, 119 persons were identified from a sample of 198 persons with schizophrenia age 55 or older who developed the disorder before age 45; for comparison, 57 persons were identified from a group of 113 without the disorder. The groups were compared for treatment of one or more of four common medical disorders. Thirteen independent variables were inserted into Krause's model for the comparisons. A dependent variable was created to indicate whether persons received medication treatment for all of their medical disorders (high-treatment group). Significant differences were found between the schizophrenia and control groups in the proportion receiving treatment for the four physical conditions (.61 versus .83, respectively, p=.004). By logistic regression, four of 13 variables for the schizophrenia group were significantly associated (p
