The purpose was to develop and validate a new instrument suitable for measuring perceived quality of life in women with breast cancer. The instrument is to be used within conventional cancer therapy as well as in complementary care, and is called the LSQ-32 (Life Satisfaction Questionnaire). The subjects were 362 women with breast cancer in all cancer stages. Cronbach's alpha reliability coefficient of the LSQ was 0.89. The construct validity was estimated by a principal component analysis. Six orthogonal factors were identified: (1) 'Quality of family relation', (2) 'Physical symptoms', (3) 'Socioeconomic situation', (4) 'Quality of daily activities', (5) 'Sickness impact' and (6) 'Quality of close friend relation'. The criterion-related validity was estimated by comparing the LSQ-32 and the EORTC QLQ-C30. The scales/items of the EORTC QLQ-C30 were represented in the LSQ-32, but the factors 'Quality of family relation' and 'Quality of close friend relation' were not found in the EORTC QLQ-C30. It was concluded that the LSQ-32 as well as the EORTC QLQ-C30 are valuable tools in the measurement of quality of life in women with breast cancer. The LSQ-32, however, also contains an existential factor.
目的是开发并验证一种适用于测量乳腺癌女性生活质量感知的新工具。该工具将用于传统癌症治疗以及辅助护理中，名为LSQ - 32（生活满意度问卷）。研究对象为362名处于所有癌症阶段的乳腺癌女性。LSQ的克朗巴哈α信度系数为0.89。通过主成分分析估计结构效度。确定了六个正交因子：（1）“家庭关系质量”，（2）“身体症状”，（3）“社会经济状况”，（4）“日常活动质量”，（5）“疾病影响”和（6）“亲密朋友关系质量”。通过比较LSQ - 32和EORTC QLQ - C30估计效标关联效度。EORTC QLQ - C30的量表/条目在LSQ - 32中有体现，但EORTC QLQ - C30中未发现“家庭关系质量”和“亲密朋友关系质量”这两个因子。得出的结论是，LSQ - 32以及EORTC QLQ - C30都是测量乳腺癌女性生活质量的有价值工具。然而，LSQ - 32还包含一个生存因素。
