背景本研究旨在评估癌症患者一般需求评估工具（支持性护理需求调查）的表面、内容、结构效度和内部信度。共有1492名连续患者参加了澳大利亚新南威尔士州9个癌症治疗中心的外科、放射或内科肿瘤科。在1370例合格患者中，1354例（99%）同意参与，888例（65%）完成了调查。合格的同意患者接受支持性护理需求调查，在家中完成，并在7天内通过邮件返回。在结构效度评估中，主成分分析法确定了特征值大于1的5个因素，它们共同解释了总方差的64%（患者在心理、卫生系统和信息、身体和日常生活、患者护理和支持以及性方面的需求）。经过初步测试和阅读难易度测试，发现表面效度和内容效度都很高。所有5个因素为基础的量表的内部信度系数（Cronbach α）被认为是实质性的，范围从0.87到0.97。这些结果表明，支持性护理需求调查提供了一个可靠和有效的指标，全球肿瘤患者的需求。建议在进一步完善和评价后，将这一工具标准化并广泛应用。[See相关文章226-37页，本期。Cancer 2000;88：217-25.

BACKGROUND. This study aimed to assess the face, content, and construct validity and the internal reliability of a tool for assessing the generic needs of patients with cancer (the Supportive Care Needs Survey).METHODS. A total of 1492 consecutive patients attending the surgical, radiation, or medical oncology departments of 9 cancer treatment centers in New South Wales, Australia, were asked to participate. Of the 1370 eligible patients, 1354 (99%) consented to participate and 888 (65%) completed the survey. Eligible consenting patients were given a Supportive Care Needs Survey to complete at home and return by mail within 7 days.RESULTS. In the assessment of construct validity, the principal components method of factor analysis identified 5 factors with eigenvalues greater than 1, which together accounted for 64% of the total variance (patients' needs in the domains of psychologic, health system and information, physical and daily living, patient care and support, and sexuality). Face and content validity were found to be high following pilot tests and tests of reading ease. Internal reliability coefficients (Cronbach alpha) of all 5 factor-based scales were found to be substantial, ranging from 0.87 to 0.97.CONCLUSIONS. These findings suggest that the Supportive Care Needs Survey provides a reliable and valid index of the global needs of oncology patients. The standardized and widespread application of this instrument is recommended following further refinement and evaluation. [See related article on pages 226-37, this issue.] Cancer 2000;88:217-25.
