aims to map out the connectivity between anxiety, depression and pain symptoms amongst Chinese AYA cancer patients from the perspective of a network model. Methods: Two hundred and eighteen AYA patients, aged between 15 and 39 years at diagnosis; completed the Patient Health Questionnaire (PHQ), Generalized Anxiety Disorder (GAD), and McGill Pain Questionnaire-Visual Analogue Scale (MPQ-VAS). Network analyses were performed. Results: In all, 38.07% (95% CI = 31.58– 44.57%) of the participants reported depression, 30.73% (95% CI = 24.56– 36.91%) reported anxiety, and 14.22% (95% CI = 9.55– 18.89%) reported current pain. The generated network illustrated that anxiety, depression and pain community were well connected. In the network, "having trouble relaxing" (GAD4, node strength = 1.182), "uncontrollable worry" (GAD2, node strength = 1.165), and "sad mood" (PHQ2, node strength = 1.144) were identified as the most central symptoms, while "uncontrollable worry" (GAD2, bridge strength = 0.645), "guilty" (PHQ6, bridge strength = 0.545), and "restlessness" (GAD5, bridge strength = 0.414) were the key bridging symptoms that connected different communities. Conclusion: Anxiety, depression and pain symptoms are highly interactive with each other. Alleviating AYA cancer patient's excessive worries might be helpful in improving the patient's co-occurring anxiety, depression and pain symptoms. [ABSTRACT FROM AUTHOR]
