The aim was to assess the association between cognitive and emotional symptom representations prior to diagnosis and the length of the patient interval (i.e. the time from the first symptom is experienced until healthcare is sought) for colorectal cancer patients.
The study population included 436 newly diagnosed colorectal cancer patients. Questionnaire data were collected using the Danish Revised Illness Perception Questionnaire (IPQ-R), including cognitive and emotional symptom representations and information on the patient interval.
High score in treatment control was associated with short patient interval (PR = 0.52, 95% CI: 0.31-0.89) and high score on the timeline cyclical dimension was associated with long patient interval (PR = 2.14, 95% CI: 1.29-3.57). Hence, patients with negative beliefs about the treatability of their symptoms and patients with strong beliefs about the cyclical nature of their symptoms were more likely to have a long patient interval. Assigning blood in stool as the most important symptom significantly interacted in the association between the patient interval and the two cognitive symptom representations consequence and personal control.
The results indicate that aspects of symptom representations were associated with the patient's help-seeking.
These findings may help clinicians and public health planners shorten patient intervals.
旨在评估结直肠癌患者诊断前认知和情绪症状表现与患者间隔时间（即从首次出现症状到寻求医疗护理的时间）之间的关联。
研究人群包括436例新诊断的结直肠癌患者。使用丹麦修订版疾病认知问卷（IPQ-R）收集问卷数据，包括认知和情绪症状表现以及患者间隔时间的信息。
治疗控制方面得分高与患者间隔时间短相关（风险比[PR]=0.52，95%置信区间[CI]：0.31-0.89），时间轴周期性维度得分高与患者间隔时间长相关（PR=2.14，95%CI：1.29-3.57）。因此，对症状可治疗性持负面信念的患者以及对症状周期性持强烈信念的患者更有可能有较长的患者间隔时间。将便血视为最重要的症状在患者间隔时间与两种认知症状表现（后果和个人控制）之间的关联中存在显著交互作用。
结果表明症状表现的各个方面与患者寻求帮助有关。
这些发现可能有助于临床医生和公共卫生规划者缩短患者间隔时间。
