Examination of daily-level associations between posttraumatic stress disorder symptoms and COVID-19 worries.

OBJECTIVE

Stressors and worries related to the COVID-19 pandemic have contributed to the onset and exacerbation of psychological symptoms such as posttraumatic stress disorder (PTSD). Using a microlongitudinal framework, we uniquely investigated bidirectional associations between daily-level PTSD symptoms and COVID-19 worries.

METHOD

Data from 42 trauma-exposed university students ( = 22.67 ± 5.02, 86.7% female) were collected between March and August 2020. Participants completed daily surveys for 10 days to assess PTSD symptom severity and COVID-19 worries. Multilevel regression was conducted to examine both lagged and simultaneous models of daily person-centered mean PTSD symptom severity predicting COVID-19 worries, and vice-versa.

RESULTS

Days with greater COVID-19 worries were associated with greater same-day ( = .53, = .19, = .006) and next-day ( = .65, = .21, = .003) PTSD symptom severity. Additionally, days with greater PTSD symptom severity were associated with greater same-day COVID-19 worries ( = .06, = .02, = .006).

CONCLUSIONS

COVID-19 worries may influence same-day and next-day PTSD symptoms, and PTSD symptoms may influence same day COVID-19 worries. Findings substantiate the interplay between ongoing stress related to the COVID-19 pandemic and posttrauma symptoms and support therapeutically targeting COVID-19 stress in PTSD treatments to potentially impact posttrauma symptoms.
