Within-person worry and negative tension: secondary analysis of openESM dataset 0001

Abstract

This record contains the analysis code, results table, and README for a secondary analysis of openESM dataset 0001 (Fried, Papanikolaou & Epskamp, 2022; Clinical Psychological Science, doi:10.1177/21677026211017839). The data come from an ecological momentary assessment study of 80 undergraduate psychology students at Leiden University in March 2020, with four prompts per day for 14 days. The analysis uses 79 participants with EMA data and 3,938 answered prompts. It examines whether worry predicts negative tension within persons, and whether same-day lagged associations between worry and tension remain after controlling for prior scores of the outcome. Measures refer to the past three hours and are rated on a 1 to 5 scale. Concurrent worry predicted tension within persons (γ = 0.350, 95% CI [0.325, 0.374], autoregression controlled). Lagged cross-effects were positive without autoregressive control and negative with it, in both directions, so they are not interpreted as carryover. Random-slope models converged. The record includes the R script (fried_covid_lag_analysis.R), the results table (lag_results.csv), and a README with the cleaning rules, sample flow, and software versions. The raw data are available from openESM under CC BY 4.0.
