Reliability, validity, and sensitivity of the Chinese Life Attitude Self-rating Questionnaire for Breast Cancer.
Rationale, aims and objectives: Psychometrics of the Chinese Life Attitude Self-rating Questionnaire for Breast Cancer (LASQ-BC) has not yet been conducted in a larger sample of women with breast cancer. This study aimed to examine the reliability, validity, and sensitivity of the LASQ-BC in Chinese mainland female breast cancer patients.
Method: This is a cross-sectional study. Reliability was determined by Cronbach's α and Guttman split-half coefficient. Convergent and discriminant validity were evaluated via item-subscale and item-total score correlations. Factorial validity was estimated using a principal component analysis with varimax rotation. Sensitivity was identified via Cohen's effect size (ES) and an independent sample t-test between the new and recurrent cases. Multiple linear regression analysis was used to further examine sensitivity of the LASQ-BC under the influence of newly diagnosed breast cancer (yes vs. no).
Results: A total of 429 patients completed the questionnaire. Cronbach's α of the LASQ-BC was 0.96, ranging from 0.86 to 0.92 for the four subscales (i.e., choice and responsibility, life meaning, benevolence, and life experiences). The Guttman split-half coefficient was 0.90. The hypothesised item-subscale and item-total score correlations were higher than the critical value of 0.50. Four factors were extracted from the 23 items, explaining 69.29% of the total variance. Eligible ES (range: 0.38-0.48) was found in the four subscales and total score between the new and recurrent cases (independent sample t-test), and under the influence of newly diagnosed breast cancer (yes vs. no; multiple linear regression analysis).
Conclusion: The Chinese LASQ-BC has acceptable reliability, validity, and sensitivity in women with breast cancer of mainland China. It can be used to female breast cancer patients as an invaluable metric and a crucial instrument for assessing and discerning those grappling with a suboptimal life attitude, and in gauging the efficacy of psychological interventions tailored to enhance this perspective.
期刊介绍：
The Journal of Evaluation in Clinical Practice aims to promote the evaluation and development of clinical practice across medicine, nursing and the allied health professions. All aspects of health services research and public health policy analysis and debate are of interest to the Journal whether studied from a population-based or individual patient-centred perspective. Of particular interest to the Journal are submissions on all aspects of clinical effectiveness and efficiency including evidence-based medicine, clinical practice guidelines, clinical decision making, clinical services organisation, implementation and delivery, health economic evaluation, health process and outcome measurement and new or improved methods (conceptual and statistical) for systematic inquiry into clinical practice. Papers may take a classical quantitative or qualitative approach to investigation (or may utilise both techniques) or may take the form of learned essays, structured/systematic reviews and critiques.
