Abstract

PURPOSE

Few studies have evaluated the impact of a stoma on patient quality of life because of a lack of specific validated measures. This study documents the development and initial application of a Stoma Quality of Life Scale.

METHODS

Content experts generated initial questions. Patient focus groups were conducted to ensure that the questions addressed all stoma-related issues considered important by patients. Responses from pilot groups allowed refinement to produce the final measure, the Stoma Quality of Life Scale, a 21-item questionnaire. Three scales are featured: Work/Social Function (6 items), Sexuality/Body Image (5 items), and Stoma Function (6 items). In addition, one item (scored separately) measures financial impact, one measures skin irritation, and two measure overall satisfaction. This questionnaire was administered to 100 consecutive ostomy patients, and readministered three weeks later. Reliability was assessed by using coefficient alpha for internal consistency and intraclass correlation coefficient for test-retest reproducibility. To test validity in extreme groups, scores were compared for patients with improved quality of life vs. those whose stoma worsened their quality of life. To evaluate convergent validity, we analyzed correlation of instrument scales with the SF12.

RESULTS

The Stoma Quality of Life scales demonstrated adequate test-retest reproducibility (intraclass correlation coefficient>0.8) and acceptable internal consistency (coefficient alpha approximately 0.8). The scales were capable of discriminating between patients with better and worse quality of life after stoma formation (P<0.02 for all scales). The Stoma Quality of Life scales significantly correlated (range, 0.12-0.75) with the Physical and Mental Health Composite Scale Scores of the SF-12.

CONCLUSIONS

The Stoma Quality of Life Scale demonstrates reasonable psychometric properties for measuring quality of life in patients with stomas. Further studies are needed to refine the instrument.

摘要

目的

由于缺乏经过验证的特定测量方法，很少有研究评估造口对患者生活质量的影响。本研究记录了造口生活质量量表的开发和初步应用。

方法

内容专家提出初始问题。进行患者焦点小组讨论，以确保这些问题涵盖了患者认为重要的所有与造口相关的问题。试点组的反馈使得量表得以完善，最终形成了造口生活质量量表，这是一份包含21个条目的问卷。该量表包括三个分量表：工作/社交功能（6个条目）、性/身体形象（5个条目）和造口功能（6个条目）。此外，一个条目（单独计分）测量经济影响，一个条目测量皮肤刺激，两个条目测量总体满意度。该问卷连续发放给100名造口患者，并在三周后再次发放。通过计算内部一致性系数α评估信度，通过计算组内相关系数评估重测信度。为了在极端组中测试效度，比较了生活质量改善的患者与造口使生活质量恶化的患者的得分。为了评估收敛效度，我们分析了该量表各分量表与SF12的相关性。
