Radiotherapy is one of the major methods for treating cancer, but many patients undergoing radiotherapy have deep concerns about receiving radiation treatment. This problem is not generally appreciated and has not been adequately studied.
The objective of this investigation was to empirically investigate the anxieties that cancer patients feel towards radiotherapy by using questionnaires to classify and quantitatively measure their concerns. A preliminary interview to develop a questionnaire was carried out with 48 patients receiving radiotherapy to discover their anxieties about on-going treatments. Subsequently, a main study was performed using a questionnaire with 185 patients to classify their types of anxiety and to ascertain the reliability and validity of the responses. Confirmatory factor analysis was then carried out with a 17-item Radiotherapy Categorical Anxiety Scale.
Three anxiety factors were abstracted by factor analysis: (1) adverse effects of radiotherapy, (2) environment of radiotherapy, and (3) treatment effects of radiotherapy. Reliability, content validity, and concurrent validity were obtained. The adequacy of the three-factor model of anxiety concerning radiotherapy was confirmed.
A 17-item Radiotherapy Categorical Anxiety Scale was formulated to quantitatively measure the specific types of anxiety among cancer patients receiving radiotherapy.
放射治疗是治疗癌症的主要方法之一，但许多接受放射治疗的患者对接受辐射治疗深感担忧。这个问题并未得到普遍重视，也未得到充分研究。
本研究旨在通过问卷调查对癌症患者对放射治疗的焦虑进行实证研究，对其担忧进行分类和定量测量。对 48 名接受放射治疗的患者进行了初步访谈，以开发出问卷，以了解他们对正在进行的治疗的焦虑。随后，对 185 名患者进行了一项主要研究，使用问卷对他们的焦虑类型进行分类，并确定反应的可靠性和有效性。然后，使用 17 项放射治疗分类焦虑量表进行验证性因素分析。
通过因子分析得出三个焦虑因子：（1）放射治疗的不良反应，（2）放射治疗环境，（3）放射治疗效果。获得了可靠性、内容有效性和同时有效性。放射治疗焦虑的三因素模型的充分性得到了确认。
制定了一个 17 项放射治疗分类焦虑量表，用于定量测量接受放射治疗的癌症患者的特定类型的焦虑。
