Abstract

Background

Personal health-related resources are essential for women with breast cancer, as these help them to maintain their own health and well-being during cancer care. Nurses play an important role in providing support to identify personal health-related resources of women during cancer treatments.

Purpose

To develop and test the psychometric properties of a new self-assessment personal health-related resources (PHRR) instrument for working-age women receiving breast cancer care.

Methods

A four-phase instrument development process was used. The data were analysed using the content validity index, content validity ratio and exploratory factor analysis. Reliability was tested using Cronbach's α coefficients.

Results

The instrument’s content validity index was 0.93. Exploratory factor analysis showed that the instrument version 3.0 comprised three main factors, 12 sub-factors and 46 items, which explained 67.4 % of the total variance in the measured variable. The instrument’s internal consistency was high, with Cronbach’s α of 0.92.

Conclusion

The instrument showed acceptable psychometric properties and was suitable for measuring PHRR in women aged 18–65 years with breast cancer. The instrument provides multidimensional understanding of the PHRR of women with breast cancer. The PHRR instrument can be used to achieve a comprehensive understanding of the personal health-related resources for women with breast cancer during cancer care. This instrument can provide information how to support women and development psychosocial support in different phases of illness.

针对患有乳腺癌的工作年龄妇女的个人健康相关资源工具的开发和心理测量测试

背景：个人健康相关资源对患有乳腺癌的妇女至关重要，因为这些资源有助于她们在癌症治疗期间保持自身的健康和福祉。护士在提供支持以确定癌症治疗期间妇女的个人健康相关资源方面发挥着重要作用。目的开发并测试一种新的工作年龄妇女接受乳腺癌护理的个人健康相关资源自我评估（PHRR）工具的心理测量学特性。方法采用四阶段仪器研制流程。采用内容效度指标、内容效度比和探索性因子分析对数据进行分析。采用Cronbach′s α系数检验信度。结果该仪器的内容效度指数为0.93。探索性因子分析表明，3.0版仪器包含3个主因子，12个子因子，46个项目，解释了被测变量总方差的67.4% %。仪器内部一致性高，Cronbach’s α为0.92。结论该仪器具有良好的心理测量性能，适用于18 ~ 65岁乳腺癌患者的PHRR测量。该工具提供了对乳腺癌妇女的PHRR的多维理解。PHRR工具可用于全面了解乳腺癌妇女在癌症治疗期间的个人健康相关资源。这一工具可以提供如何在疾病的不同阶段支持妇女和发展社会心理支持的信息。
