    BackgroundPain and mood disturbances, such as anxiety and depression, are common symptoms in gynecologic cancer. Their associations and the role of personality traits in pain adaptation during chemotherapy remain unclear. This ancillary data analysis aimed to investigate these relationships.AimTo (1) depict the temporal trend of daily pain severity; (2) evaluate dynamic associations between mood and pain; and (3) explore personality traits (neuroticism and conscientiousness) as moderators of the mood-pain relationship during chemotherapy for gynecologic cancer.MethodSymptom severity was assessed daily throughout chemotherapy, while personality, clinical, and demographic characteristics were assessed at baseline. Twenty-seven women with gynecologic cancer who completed daily symptom assessments for at least four cycles were included in the analyses.ResultsPain severity decreased slightly during chemotherapy. Multilevel modeling supported significant associations between pain and anxiety (b = 0.24, standard error [SE] = 0.06, p = .001) and depression (b = 0.30, SE = 0.08, p = .002). Time-varying effect modeling showed significant associations between anxiety and pain that initially increased and then decreased; and significant associations between depression and pain steadily decreased over the first four cycles of chemotherapy. Neuroticism moderated the association between anxiety and pain (b = 0.15, SE = 0.06, p < .05), with anxiety more strongly associated with pain in those with higher neuroticism.ConclusionsThis study highlights the dynamic nature of pain and its associations with anxiety and depression in individuals with gynecologic cancer undergoing chemotherapy. The findings have implications for understanding pain and developing tailored psychosocial symptom management interventions to prevent pain during chemotherapy.Copyright © 2023.
