Fine-Grained Assessment of Nonsuicidal Self-Injury

This chapter focuses on the use of fine-grained assessment approaches in nonsuicidal self-injury (NSSI) research. Fine-grained assessment has enabled researchers to collect near real-time information about the proximal precipitants, consequences, and correlates of NSSI; test theoretical models in ecologically valid contexts; and further our understanding of the temporal sequencing of NSSI-related events. The chapter begins by discussing the need to balance benefits against the potential costs in the context of choosing the frequency, timing, and duration of study assessments, as well as measurement strategies for NSSI and other variables. It then considers some of the unique ethical and technical challenges that are inherent within fine-grained assessment studies. The chapter also offers recommendations for maximizing participant compliance and retention, navigating technological challenges, limiting recruitment or selection biases, and implementing effective risk assessments. Finally, this chapter explores frontiers in the area of fine-grained NSSI assessment, providing recommendations for future work and summarizing potential clinical applications of these methods.
