    Abstract:
    AIMS: This study aimed to examine the relationships between gastroparesis symptom severity, illness perceptions, coping styles, quality of life (QoL), and psychological distress in patients with gastroparesis, guided by the common sense model. METHODS: One hundred and seventy-nine adults with gastroparesis (165 females, 14 males; mean age 41.82 years) completed an online questionnaire. The Gastroparesis Cardinal Symptom Index was used to measure gastroparesis symptom severity, QoL was explored using the PAGI-QOL, illness perceptions were measured using the Brief Illness Perception Questionnaire, the Carver Brief COPE scale assessed coping styles, and psychological distress was investigated using the DASS21. RESULTS: Structural equation modeling resulted in a final model with excellent fit. Gastroparesis symptom severity directly influenced illness perceptions (β = .52, p < .001) and QoL (β = .30, p < .001). Illness perceptions directly influenced maladaptive coping (β = - .64, p < .001), psychological distress (β = - .32, p < .001), and QoL (β = .30, p = .01). Maladaptive coping directly influenced psychological distress (β = .62, p < .001), which in turn had a direct influence on QoL (β = - .38, p < .001). CONCLUSIONS: The final model showed that the influence of gastroparesis symptom severity on psychological distress was fully mediated by illness perceptions, while the influence on QoL was partially mediated by illness perceptions. The study provides guidance for the development of psychological interventions targeted toward improving mediating psychological factors.
