Abstract

Background

The efficacy of radiotherapy and the satisfaction of patients can be significantly improved by adequately addressing their information needs. This process is impeded by the current lack of a comprehensive tool for assessing these needs.

Objective

To develop an Information Needs Questionnaire for patients with breast cancer undergoing radiotherapy and to assess its reliability and validity.

Methods

The initial item pool for the questionnaire was developed through a literature analysis and semi-structured interviews with 12 patients with breast cancer receiving radiotherapy. The Delphi method was employed to consult 16 experts and the questionnaire content was refined based on expert feedback and item ratings to form the first draft. A pre-investigation was conducted on 30 patients with breast cancer treated with radiotherapy to refine the item expression. From March–October 2024, item analysis, factor analyses, and reliability tests were conducted on 220 patients. This study adhered to STROBE guidelines.

Results

The final questionnaire comprised 36 items. Exploratory factor analysis revealed 5 dimensions, with all item factor loading within their respective dimensions being ≥ 0.4 and no items exhibiting multiple loadings. These five factors accounted for 72.805% of the total variance. The overall content validity index was 0.980, with item-level content validity index ranging from 0.900 to 1.000. The Cronbach's α coefficient for the entire questionnaire was 0.959, and the coefficients for each dimension ranged from 0.786 to 0.958.

Conclusion

The Information Needs Questionnaire demonstrated excellent reliability and validity in patients with breast cancer undergoing radiotherapy. It can effectively guide medical staff to accurately assess the information needs of patients with breast cancer who are undergoing radiotherapy.

Relevance to Clinical Practice

Identifying the authentic informational needs of breast cancer patients throughout the entire radiotherapy process is instrumental in enabling medical staff to devise personalised and targeted information support interventions.

Patient or Public Contribution

A total of 220 participants provided perspectives on their information needs.

乳腺癌放疗患者信息需求问卷中文版的编制与验证。

背景：充分满足患者的信息需求，可以显著提高放疗的疗效和患者的满意度。由于目前缺乏评估这些需要的全面工具，这一进程受到阻碍。目的：编制乳腺癌放疗患者信息需求问卷，并对问卷的信效度进行评价。方法：对12例接受放疗的乳腺癌患者进行文献分析和半结构化访谈，形成问卷的初始题库。采用德尔菲法对16位专家进行咨询，根据专家反馈和项目评分对问卷内容进行细化，形成初稿。对30例接受放疗的乳腺癌患者进行预调查，完善项目表达。从2024年3月至10月，对220例患者进行项目分析、因素分析和信度检验。本研究遵循STROBE指南。结果：最终问卷共36个项目。探索性因子分析显示5个维度，各维度内所有项目因子加载均≥0.4，没有项目存在多重加载。这5个因素占总方差的72.805%。整体内容效度指数为0.980，项目层面内容效度指数为0.900 ~ 1.000。整个问卷的Cronbach's α系数为0.959，各维度系数为0.786 ~ 0.958。结论：信息需求问卷对乳腺癌放疗患者具有良好的信度和效度。可以有效指导医护人员准确评估乳腺癌放疗患者的信息需求。与临床实践的相关性：确定乳腺癌患者在整个放射治疗过程中的真实信息需求，有助于医务人员制定个性化和有针对性的信息支持干预措施。患者或公众贡献：共有220名参与者就其信息需求提供了观点。

期刊介绍： The Journal of Clinical Nursing (JCN) is an international, peer reviewed, scientific journal that seeks to promote the development and exchange of knowledge that is directly relevant to all spheres of nursing practice. The primary aim is to promote a high standard of clinically related scholarship which advances and supports the practice and discipline of nursing. The Journal also aims to promote the international exchange of ideas and experience that draws from the different cultures in which practice takes place. Further, JCN seeks to enrich insight into clinical need and the implications for nursing intervention and models of service delivery. Emphasis is placed on promoting critical debate on the art and science of nursing practice. JCN is essential reading for anyone involved in nursing practice, whether clinicians, researchers, educators, managers, policy makers, or students. The development of clinical practice and the changing patterns of inter-professional working are also central to JCN''s scope of interest. Contributions are welcomed from other health professionals on issues that have a direct impact on nursing practice. We publish high quality papers from across the methodological spectrum that make an important and novel contribution to the field of clinical nursing (regardless of where care is provided), and which demonstrate clinical application and international relevance.
