Diagnosis: Earlier Looking At Your Symptoms - development of a patient-centred tool to measure diagnostic delays

Study hypothesis: This pilot study aims to determine the acceptability (to patients and research nurses), feasibility and validity of a tool to measure patient and primary delays in cancer. In particular this work will:
1. Pilot the recruitment of patients with a recent and established diagnosis of one of seven specific cancers (or groups of cancers) and the administration of the tool by research nurses
2. Assess non-response bias
3. Assess and seek ways to minimize the level of anxiety that may be raised as part of the data collection process
4. Assess completion rates
5. Compare the response to the tool being administered by a research nurse with self-completion facilitated by a research nurse
Primary outcome(s): To compare the two groups in terms of overall completion rates using an intention to treat analysis

研究假设：本先导性研究旨在评估一款用于测量癌症患者相关延误与首诊医疗延误的工具的可接受性（面向患者与研究护士）、可行性与有效性。具体而言，本研究将开展以下工作：
1. 针对近期确诊7种特定癌症（或癌症群组）的患者开展先导性招募，并由研究护士完成该工具的施测
2. 评估无应答偏倚
3. 评估数据收集过程中可能引发的焦虑水平，并探索相应的缓解策略
4. 评估完成率
5. 对比研究护士直接施测与研究护士协助患者自主填写两种方式下的工具应答情况
主要结局指标：采用意向性治疗分析，对比两组患者的总体完成率
