Evaluated the psychometric properties of the Cancer Inventory of Problem Situations (CIPS), a cancer-specific survey instrument designed to assess day-to-day problems and rehabilitation needs of cancer patients. A heterogeneous group of 479 cancer patients participated in the research. The substructure of the CIPS was investigated using factor-analytic techniques. The CIPS was factored into 31 clinically useful subscales. Further analyses led to five higher order factors representing the physical, psychosocial, medical interaction, marital, and sexual problem areas characteristic of cancer and its treatment. Internal consistency of all the scales was high (mean alpha = .81). The test-retest reliability and validity of the instrument were also studied in a sample of 120 patients. Analyses of items, subscales, higher order factors, and total CIPS scores suggest excellent reliability. The pattern of correlations of the CIPS with other measures (psychological distress; physical, marital, and sexual functioning; and quality of life) provided preliminary evidence of concurrent, discriminant, and convergent validity. The CIPS appears to have sound psychometric properties and fills an important gap in the assessment of cancer patients for both clinical and research purposes.
评估了癌症问题情境量表（CIPS）的心理测量特性，这是一种针对癌症患者设计的特定调查工具，用于评估癌症患者的日常问题和康复需求。479名癌症患者组成的异质性群体参与了该研究。使用因子分析技术研究了CIPS的子结构。CIPS被分解为31个具有临床实用性的分量表。进一步分析得出五个高阶因子，分别代表癌症及其治疗所特有的身体、心理社会、医疗互动、婚姻和性问题领域。所有分量表的内部一致性都很高（平均α系数 = 0.81）。还在120名患者的样本中研究了该工具的重测信度和效度。对项目、分量表、高阶因子和CIPS总分进行分析，结果显示出极高的信度。CIPS与其他测量指标（心理困扰、身体、婚姻和性功能以及生活质量）的相关模式为同时效度、区分效度和聚合效度提供了初步证据。CIPS似乎具有良好的心理测量特性，并且在临床和研究目的的癌症患者评估中填补了一个重要空白。
