Data from seven assessment points over 18 months, at 3-month intervals, were used. The two outcomes were assessed at all points.  \nThis is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made.  \n© 2023 The Authors.

MachineLearning techniques were used to detect latent patterns of change and identify the most important predictors.  \nResults: Five trajectories were identified for each outcome: stably high, high with fluctuations, recovery, deteriorating/delayed response, and stably poor well-being (chronic distress). Psychological factors (i.e., negative affect, coping, sense of control, social support), age, and a few medical variables (e.g., symptoms, immunerelated inflammation) predicted patients' participation in the delayed resp","cbCaigaGs2oezURx","https://ap.wps.com/l/cbCaigaGs2oezURx","pdf",716327,1,9,"English","en",105,"# Abstract\n## Objective\n## Methods\n## Results\n## Conclusions\n# Background\n## Breast cancer distress over time\n## Dynamic trajectories of adaptation","[{\"question\":\"What is the study’s main objective?\",\"answer\":\"To describe distinct well-being and anxiety/depression symptom trajectories over 18 months after breast cancer diagnosis and identify predictors for those trajectories.\"},{\"question\":\"How was the study conducted and analyzed?\",\"answer\":\"A cohort of 474 women was assessed at seven time points over 18 months.
