ObjectiveAssessment in palliative care requires a multidimensional review of physical symptoms and psychosocial concerns in a format appropriate for patients with advanced illness. In this study, we describe the initial development and validation of a structured interview for assessing common symptoms and concerns faced by terminally ill individuals.MethodWe constructed a 13-item Structured Interview for Symptoms and Concerns (SISC) based on a review of end-of-life issues and administered it to 69 patients receiving palliative care for advanced cancer. Along with the interview, each participant completed visual analog scales (VAS) addressing the same constructs. Test-retest and interrater reliability were determined, as was the concordance between interview ratings and VAS scores.ResultsOverall, the interview items had excellent interrater reliability (intraclass correlations were > 0.90) and at least moderate temporal stability (test-retest correlations ranged from 0.50 to 0.90). Concurrent validity was evident in the good concordance between interview items and VAS measures (correlations were > 0.70). The SISC was also sensitive to individual differences between subgroups of participants who did or did not meet diagnostic criteria for anxiety or depressive disorders.ConclusionsThis study demonstrates that structured interviews provide a reliable and valid approach to assessment in palliative care and may be an appropriate alternative for some research applications.
