An exponential effect persistence model for intensive longitudinal data.

ABSTRACT: We develop an effect persistence model for intensive longitudinal data under a general assumption of an exponential loss of association between exposure and outcome over time. The working model proposed may be useful for understanding the complexity of phenomena for which subjects can be repeatedly exposed to an intervention or a naturally occurring event, while, the effect of any one exposure is expected to diminish over time. Under the main assumption, we specify a semilinear model with extensions to generalized linear models. These methods are motivated by, and applied to, data from a study of adolescent exposure to prosmoking advertisement in which the impact of prosmoking media exposure on young adults' susceptibility to smoking is assessed along with the decay of the effect over time
