Posttraumatic Growth in Radiation Medicine During the COVID-19 Outbreak

It has been reported that adversarial growth during traumatic events potentially enhances coping with sequelae. The purpose of this work was to assess posttraumatic growth (PTG) among radiation medicine staff members at the individual level as well as changes in perceptions of departmental culture after the COVID-19 pandemic.

An anonymous PTG inventory (PTGI) survey comprising 21 indicators was disseminated to all 213 members of our multicenter radiation department to measure perceptions of change in personal, interpersonal-relationship, and philosophy of life factors using principal-factor analysis. Additionally, 8 department safety-culture indicators from the National Hospital Patient Safety Culture Survey developed by the Agency for Healthcare Research and Quality were included to assess changes in department safety-culture perceptions verses a prepandemic survey. The survey was repeated 15 months later to assess longitudinal trends.

With a 56.3% survey-response rate, PTGI factor analysis yielded Cronbach's alpha values exceeding 0.90 for the 3 aforementioned PTG factors. The average growth per indicator was 2.3 (out of 5.0), which fell between small and moderate. The values were 2.4 (personal), 2.1 (interpersonal), and 1.6 (philosophy) for the 3 factors. The total PTGI score (47.7 ± 28.3 out of 105 points) was lower for masked, patient-facing, frontline workers members (41.8 ± 28.4) compared with others (53.1 ± 27.3, P value .001). For the Agency for Healthcare Research and Quality survey there was an improvement of 15% in perceptions of department safety culture, and 7 of the 8 indicators showed improvements compared with baseline. The follow-up survey demonstrated overall sustained findings, albeit with a trend toward declining PTG scores for nonfrontline workers, notably in interpersonal relationships (47.4 ± 27.0, P value .05).

A fair-to-moderate degree of PTG was observed in personal and interpersonal relationship factors whereas least growth was noted in spiritual and religious beliefs. Perceptions of department patient-safety culture improved substantially. Sustained improvements were thus perceived at the individual and department levels.
