Network analysis of psychosomatic symptoms in pharmacists during the pandemic

We explored the networks and discriminant abilities of the current Psychosomatic Symptoms Scale (PSSS) in pharmacists for future abbreviation. Ten thousand seven hundred twenty-one pharmacists participated in this study through an online investigation. We used network analysis to reveal the central and bridge symptoms between the subscales (psychological and somatic symptoms) of the PSSS. Then, we utilized item response theory (IRT) to identify discriminant abilities of the current 26-item of PSSS. Over twenty percent of the pharmacists were troubled with significant psychosomatic issues during the pandemic. Risk factors included age, lack of support, and impaired general health conditions. The network analysis revealed that "Irritability" was central to the psychological subscale and "Fatigue" was central to the somatic subscale. "Irritability-Fatigue," "Fatigue-Obsession," and "Self-injury idea-Perineum discomfort" was bridging between the somatic and psychological subscales. IRT found that "Anhedonia," "Depression," "Tightness," "Palpitations," and "Difficulty breathing" were highly discriminated. A future version of PSSS could be abbreviated according to the highlighted items, and they should also be emphasized in future psychosomatic research and targets for intervention.
