Measuring Process and Outcome in CALM
This chapter considers the qualitative and quantitative evidence base for Managing Cancer and Living Meaningfully (CALM) and the role of relevant, validated measures in substantiating its effectiveness and informing its clinical practice. The early qualitative evidence for the benefit of CALM is reviewed and the challenges inherent in generating meaningful quantitative results in an advanced cancer population are described. An important component of the early work on CALM included the development and validation of measures to assess relevant outcomes in this population. This resulted in development of new measures of distress related to death and dying and of perceived clinical benefit from CALM, and of modified measures for attachment security, quality of life, and treatment integrity. The results of a large randomized controlled trial (RCT) demonstrating the effectiveness of CALM are presented and the unique value of measures of treatment process and treatment integrity are described. Finally, the clinical utility of outcome and process measures in terms of guiding CALM therapy is considered.
