Prevalence of mood disorders and utility of the PRIME-MD in patients undergoing radiation therapy. Academic Article uri icon

Overview

abstract

  • PURPOSE: To validate a short, structured interview procedure that allows practicing oncologists to quickly and reliably identify mood disorders in their patients, and to estimate the prevalence and types of mood disorders in a radiation therapy patient setting, noting relationships between mood disorders and patient characteristics. METHODS: Consecutive, eligible adult patients from the practices of two radiation oncologists were administered the Primary Care Evaluation of Mental Disorders (PRIME-MD) by the treating physician. A subset of these patients was also evaluated with the SCID, administered by trained mental health care personnel. Agreement between the two instruments was examined using the kappa statistic. Prevalence of mood disorders was determined from the PRIME-MD. The significance of relationships between patient characteristics and mood disorders was examined by chi-square and ANOVA analysis, and subsequently by multivariate logistic regression analysis. RESULTS: One hundred twenty-two patients were studied. Fifty-three of these were administered the SCID. Agreement between the two instruments was very good (kappa = 0.70). A diagnosis of a depressive or anxiety disorder by the PRIME-MD was made in 59 of the 122 patients (48%, 95% confidence interval = 39%, 58%). Multivariate analysis showed that a diagnosis of a depressive mood disorder was significantly related to pain intensity and prior history of depression. CONCLUSION: We have demonstrated the validity and feasibility of the PRIME-MD administered by oncologists in making diagnoses of mood disorders. The prevalence of mood disorders in our set of patients undergoing a course of RT was nearly 50%. Future studies should describe the natural history of these disorders, and determine optimal intervention strategies.
