The study aimed to provide information on intrusive cognitions reported by cancer patients and to investigate for the first time whether intrusive imagery is a factor in psychological morbidity.
Matched samples of anxious (n=65) and nonanxious (n=65) patients were assessed for evidence of intrusive cognitions, including memories, images, and thoughts. Patients also completed the Mini-Mental Adjustment to Cancer Scale.
Twenty-three percent of patients reported intrusive cognitions. Cognitions were frequent, uncontrollable, and associated with significant distress. Anxious patients reported significantly more of each intrusion type than nonanxious patients, and the presence of intrusive cognitions was significantly associated with maladaptive adjustment, including anxious preoccupation and helplessness-hopelessness.
Intrusive cognitions play a significant role in anxiety and adaptation to the experience of cancer. Advancing knowledge in relation to the phenomenology of intrusions and to the manner in which intrusions can be targeted with psychological treatments is an important next stage of research.
本研究旨在提供癌症患者报告的侵入性认知信息，并首次调查侵入性意象是否是心理发病的一个因素。
对焦虑患者（n = 65）和非焦虑患者（n = 65）的匹配样本进行评估，以寻找侵入性认知的证据，包括记忆、意象和想法。患者还完成了癌症心理适应简易量表。
23%的患者报告有侵入性认知。这些认知频繁出现、无法控制，并伴有明显的痛苦。焦虑患者报告的每种侵入类型都比非焦虑患者多得多，并且侵入性认知的存在与适应不良显著相关，包括焦虑性全神贯注和无助-绝望感。
侵入性认知在焦虑和癌症体验的适应中起重要作用。进一步了解侵入现象学以及如何通过心理治疗针对侵入进行干预是下一阶段重要的研究方向。
