Suicidal Ideation Trajectories - A Latent Profile Analysis

In young and middle-aged adults, suicidal ideation is an important predictor of prospective suicide attempts, but its predictive power in late life remains unclear. In this study, we used Latent Profile Analysis (LPA) in a cohort of depressed older adults to identify distinct ideation profiles and their clinical correlates and test their association with risk of suicidal behavior longitudinally.

As the lead data analyst and the third author of this project, I performed Latent Profile Analysis, Analysis of Variance (ANOVA), and χ2 tests using R. To provide a more comprehensive view of our results, I depicted the clinical characteristics using radar plots and represented long-term changes in suicidal ideation with time-series data spanning 2500 days.
