Abstract

Objective: The Cancer Dependent Quality of Life (CancerDQoL) questionnaire asks about the impact of cancer and its treatment on individuals' quality of life (QoL). This study evaluates the psychometric properties of the CancerDQoL in a UK sample.

Methods: Patients (n = 159) with a range of cancers, recruited from Barts Health NHS Trust and Barts Maggie's Centre, completed self-administered questionnaires: CancerDQoL, EQ-5D-VAS (health status), EORTC-QLQ-C30 (predominantly health symptoms/functioning) and W-BQ16 (well-being). Based on the pre-existing -DQoL template and Item Library (Bradley), the CancerDQoL includes 23 cancer-specific life-domain items and four overview items.

Results: Exploratory factor analysis revealed a 22-item, single-factor solution. Internal consistency was excellent (α = 0.94). Cancer negatively impacted all life domains: 'feelings about future' had the most negative mean weighted (by importance) impact (WI) score. 'Physical abilities' WI scores were ranked 12th. CancerDQoL Average Weighted Impact (AWI) scores were more strongly correlated with the Cancer-dependent QoL overview item than with the General QoL or General Health overview items. As expected, the EQ-5D-VAS and EORTC-QLQ-C30 correlated together more strongly than with CancerDQoL AWI scores.

Conclusions: The CancerDQoL is the first individualised questionnaire measuring the impact of cancer and its treatment on QoL. The CancerDQoL AWI score is related to, but different from, measures of health status/functioning and well-being. Eleven CancerDQoL life-domains were more negatively impacted/important than physical abilities which is a major focus of the EQ-5D and EORTC-QLQ-C30. By revealing aspects of life most impacted by cancer and its treatment, efforts can be prioritised to improve QoL for people with cancer.

癌症依赖性生活质量（CancerDQoL）问卷的心理计量学评估：癌症及其治疗对生活质量影响的个性化测量。

调查目的癌症相关生活质量（CancerDQoL）问卷调查癌症及其治疗对个人生活质量（QoL）的影响。本研究评估了英国样本中 CancerDQoL 的心理测量特性：方法：从巴兹健康NHS信托基金会和巴兹玛吉中心招募的各种癌症患者（n = 159）填写了自填问卷：CancerDQoL、EQ-5D-VAS（健康状况）、EORTC-QLQ-C30（主要健康症状/功能）和W-BQ16（幸福感）。基于已有的-DQoL模板和项目库（Bradley），CancerDQoL包括23个癌症特定生活领域项目和4个概述项目：探索性因子分析显示了一个由 22 个项目组成的单因子解决方案。内部一致性非常好（α = 0.94）。癌症对所有生活领域都产生了负面影响：对未来的感受 "的平均加权（按重要性）影响（WI）得分最为消极。身体能力 "的 WI 分数排在第 12 位。癌症生活质量平均加权影响（AWI）得分与癌症相关生活质量概述项目的相关性比与一般生活质量或一般健康概述项目的相关性更强。不出所料，EQ-5D-VAS 和 EORTC-QLQ-C30 的相关性比 CancerDQoL AWI 分数更强：结论：CancerDQoL 是第一份测量癌症及其治疗对 QoL 影响的个性化问卷。CancerDQoL AWI得分与健康状况/功能和幸福感的测量相关，但又有所不同。与身体能力（EQ-5D 和 EORTC-QLQ-C30 的主要关注点）相比，CancerDQoL 的 11 个生活领域受到的负面影响更大/更重要。通过揭示癌症及其治疗对生活影响最大的方面，可以优先改善癌症患者的生活质量。

期刊介绍： Psycho-Oncology is concerned with the psychological, social, behavioral, and ethical aspects of cancer. This subspeciality addresses the two major psychological dimensions of cancer: the psychological responses of patients to cancer at all stages of the disease, and that of their families and caretakers; and the psychological, behavioral and social factors that may influence the disease process. Psycho-oncology is an area of multi-disciplinary interest and has boundaries with the major specialities in oncology: the clinical disciplines (surgery, medicine, pediatrics, radiotherapy), epidemiology, immunology, endocrinology, biology, pathology, bioethics, palliative care, rehabilitation medicine, clinical trials research and decision making, as well as psychiatry and psychology. This international journal is published twelve times a year and will consider contributions to research of clinical and theoretical interest. Topics covered are wide-ranging and relate to the psychosocial aspects of cancer and AIDS-related tumors, including: epidemiology, quality of life, palliative and supportive care, psychiatry, psychology, sociology, social work, nursing and educational issues. Special reviews are offered from time to time. There is a section reviewing recently published books. A society news section is available for the dissemination of information relating to meetings, conferences and other society-related topics. Summary proceedings of important national and international symposia falling within the aims of the journal are presented.
