## Abstract

Behavioral researchers are concluding that conventional group-based analyses often mask meaningful individual differences and do not necessarily map onto the change processes within the lives of individual humans. Hayes et al. (2018) have called for a renewed focus on idiographic research, but with methods capable of nuanced multivariate insights and capable of scaling to nomothetic generalizations. To that end, we present a statistical technique we believe may be useful for the task: the dynamic p-technique. The dynamic p-technique can accommodate multivariate longitudinal data and may be used to conduct single-subject and group-level analyses. After introducing the dynamic p-technique, we provide several examples of how it may be used in practice by presenting the step-by-step analyses of single-subject daily-diary dataset wherein we examined the day-to-day associations between ADHD difficulties and psychotropic medication. Although it has been underutilized by behavioral researchers, we believe p-technique analyses are particularly well-suited to model personal dynamics with nuance and within context and allow researchers to inductively build from idiographic patterns to nomothetic trends.
