The present study aimed to identify profiles of women diagnosed with breast cancer 18 months postdiagnosis based on a combination of risk and protective factors. Additionally, the study aimed to examine various potential early predictors at 3 and 6 months postdiagnosis to determine their association with the identified profiles at 18 months postdiagnosis. The sample of the study consisted of 499 women with breast cancer from four oncology centers located in Finland, Portugal, Italy, and Israel. Women completed self-report questionnaires at three time points postdiagnosis: 3, 6, and 18 months. The measures utilized included the Hospital Anxiety and Depression Scale, the Posttraumatic Stress Disorder Checklist for Diagnostic and Statistical Manual of Mental Disorders, fifth edition, the Distress Thermometer, a single item assessing self-efficacy, the Positive and Negative Affect Schedule, a single item of bounce-back ability, and the Posttraumatic Growth Inventory. Four profiles were identified: Resilience, High distress, Moderate distress, and Bouncing back coupled with distress. The primary predictors across all profiles were anxiety and depression, followed by posttraumatic growth, posttraumatic stress, self-efficacy, and bounce-back ability. This study highlighted that the challenges associated with breast cancer begin at the time of diagnosis and persist beyond the completion of treatment. Early provision of psychosocial support may facilitate improved positive adjustment 18 months postdiagnosis. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

本研究旨在基于风险和保护因素的组合，识别出确诊乳腺癌后18个月女性患者的特征性档案。此外，该研究还试图在确诊后的3个月和6个月时确定各种潜在早期预测指标，以评估它们与确诊后18个月时所识别档案之间的关联。这项研究的样本包括来自芬兰、葡萄牙、意大利和以色列四个肿瘤中心的499名乳腺癌女性患者。参与者在诊断后的三个时间点完成了自评问卷：3个月、6个月和18个月。使用的测量工具包括医院焦虑抑郁量表（Hospital Anxiety and Depression Scale）、《精神疾病诊断与统计手册》第五版创伤后应激障碍检查表（Posttraumatic Stress Disorder Checklist for Diagnostic and Statistical Manual of Mental Disorders, fifth edition）、痛苦温度计（Distress Thermometer）、自我效能单题评估、正负情绪量表（Positive and Negative Affect Schedule）、弹回能力单题评估以及创伤后成长问卷（Posttraumatic Growth Inventory）。研究确定了四个特征性档案：韧性型（Resilience）、高压力型（High distress）、中等压力型（Moderate distress）和具有弹性的压力型（Bouncing back coupled with distress）。所有特征性档案的主要预测指标是焦虑和抑郁，其次是创伤后成长、创伤后应激反应、自我效能以及弹回能力。这项研究表明，乳腺癌相关的挑战从诊断时刻开始，并且在治疗结束后持续存在。早期提供心理社会支持可能会促进患者在确诊后的18个月时更好地调整状态。（PsycInfo数据库记录（c）2025 APA，保留所有权利）。
