ANALYSES OF TURNING POINTS IN DATA

by

Patricia Cohen, Ph.D.
NYSPI and Department of Epidemiology
Columbia University


Abstract

What data analytic techniques will allow us to identify "turning points" in complex datasets with multiple time points? Our collection of month-level narrative data on role assumption and related variables over the transition from adolescence to adulthood was motivated, in part, by an interest in identifying individuals who had experienced a turning point in their lives. This interest was focused on a segment of my longitudinal cohort studied from average age 5 and with repeated full psychiatric assessments beginning at mean age 13.5 and currently at mean age 38. In this presentation I will cover 1) the cumulative evidence about methods improving narrative veracity that led to strong evidence of reliability in the data, 2) Sir Michael Rutter’s conceptual discussion of turning points in the lives of individuals, 3) Our initial efforts at identifying individuals with turning points in their lives, and 4) the methods covered in my forthcoming book, Applied Data Analytic Techniques for Turning Point Research.
