STATISTICS WORKSHOP: "NEW LONGITUDINAL METHODS FOR TRAUMA RESEARCH"

As with developmental and aging research, which uses time since birth as a fundamental methodological component, research on the sequelae to trauma has a starting date, the point of exposure, from which an individual's symptoms can be mapped and profiled as a function of time. This distinguishing aspect of trauma research makes it ideal for the application of methods designed to explicate inter-individual differences in intra-individual change and thus to gain knowledge of what points in time-since-exposure symptom trajectories may be critical to understanding chronicity or recovery and most accommodating to intervention. This workshop will introduce some of the more contemporary approaches to the analysis of longitudinal data and provide references and other resource materials to aid further inquiry. The session assumes a familiarity with multiple regression and will be presented at the novice to intermediate level.
