Abstract

CONTEXT

In applying good energy conservation strategies to relieve cancer-related fatigue, it is critical to first identify cancer patients who are at a high risk for poor energy conservation. However, instruments have not been developed to evaluate energy conservation strategies in an oncology setting.

OBJECTIVES

The aim of this study was to validate an instrument that cancer patients may use to evaluate energy conservation strategies to overcome cancer-related fatigue.

METHODS

The questionnaire development followed a four-phase process: 1) item generation and reduction, 2) construction, 3) pilot testing, and 4) field testing. Using relevant and priority criteria, as well as pilot testing, we developed a 25-item questionnaire. After field testing, five items were discarded. Finally, 20 items were included in the Energy Conservation Strategies Inventory (ECSI). Factor analysis, multitrait scaling analysis, and Cronbach's α were used to determine the construct validity and reliability.

RESULTS

Factor analyses of data from 140 cancer patients resulted in the ECSI, which covers activities related to planning, overcoming distractions, labor saving, burden reducing, and comfort. All subscales (Cronbach's α range, 0.69-0.78) and total scores (Cronbach's α=0.87) were found to possess acceptable internal consistency.

CONCLUSIONS

The good psychometric properties of the ECSI instrument show that it may be useful for measuring the frequency of energy conservation strategies used by cancer patients.

摘要

背景

在应用良好的能量节约策略来缓解与癌症相关的疲劳时，首先识别出那些能量节约能力较差的癌症患者至关重要。然而，目前还没有开发出用于评估肿瘤学环境中能量节约策略的工具。

目的

本研究旨在验证一种工具，该工具可供癌症患者用于评估克服与癌症相关的疲劳的能量节约策略。

方法

问卷的开发遵循了四个阶段的过程：1）项目生成和减少，2）构建，3）试点测试，4）现场测试。使用相关和优先标准以及试点测试，我们开发了一个包含 25 个项目的问卷。经过现场测试，有 5 个项目被删除。最终，20 个项目被纳入能量节约策略清单（ECSI）。使用因子分析、多特质标度分析和克朗巴赫 α 来确定结构效度和信度。
