Note: N = 893. Clusters are based on Ward’s method using squared euclidean distance metric. PTGI = Posttraumatic Growth Inventory. CDS = COVID-19 Disability Scale. SHAI = Shortened Health Anxiety Inventory. PHQ-4=Patient Health Questionnaire – 4. CSS = COVID Stress Scales. DAN = Danger and Contamination Fears. XEN = Xenophobia Scale. SEC = Socioeconomic Consequences Scale. CHE = Checking and Reassurance Seeking Scale. TSS = Traumatic Stress Symptoms Scale. Positive values on the change scores indicate increasing scores. Negative values on the change scores indicate decreasing scores.

One-way between subjects ANOVAs were bootstrapped with 2500 samples using 99.9 % CIs. Omnibus F-tests results were as follows: F(3, 889) = 67.0, p < .001, η_p² = .18 for PTGI; F(3, 889) = 164.8, p < .001, η_p² = .34 for CDS; F(3, 889) = 48.9, p < .001, η_p² = .14 for SHAI change; F(3, 889) = 41.4, p < .001, η_p² = .12 for PHQ change; F(3, 889) = 375.5, p < .001, η_p² = .56 for CSS change; F(3, 889) = 167.3, p < .001, η_p² = .36 for DAN change; F(3, 889) = 93.9, p < .001, η_p² = .24 for XEN change; F(3, 889) = 111.3, p < .001, η_p² = .27 for SEC change; F(3, 889) = 76.3, p < .001, η_p² = .21 for CHE change; F(3, 889) = 117.1, p < .001, η_p² = .28 for TSS change. Pairwise comparisons were conducted using Games-Howell’s post hoc test due to unequal group sizes and, in some cases, unequal variances.
