The fear of illness progression is common amongst those with chronic illnesses including cancers, and contributes to high psychological morbidity. Research in Asia on such fears however, is limited by a paucity of validated measurement instruments. Amongst the many available instruments, the Fear of Progression Questionnaire has a high quality rating, an important consideration in its selection. This study developed a simplified Mandarin version of the Fear of Progression Questionnaire - Short Form (FoP-Q-SF), and validated the English and Mandarin versions for use in Chinese populations.
The translation to a simplified Mandarin version was through a forward-backward translation with emphasis on conceptual and cultural equivalence. Cancer survivors (N = 341) completed a self-report questionnaire, the Fear of Progression Questionnaire - Short Form, other measures of fear of progression, depression, anxiety, and quality of life. Reliability and criterion validity were assessed, and the factor-structure was replicated with a confirmatory factor analysis.
The Fear of Progression Questionnaire - Short Form demonstrated high internal and test-retest reliability. Criterion validity was also demonstrated through convergent, concurrent and discriminant validity. The factor structure was supported and replicated. The goodness-of-fit indices of the original model indicated some misfit, which could be adequately addressed by freeing five parameters in the error covariance matrix, without changing the one-factor structure.
The Fear of Progression Questionnaire - Short Form is a reliable and valid measure of fear of progression applicable to a mixed-cancer survivor population in Singapore. The simplified Mandarin version of the questionnaire will be useful in other parts of Asia and for Chinese migrants in the West, further extending the use of this questionnaire.
在患有慢性病(包括癌症)的人群中,对疾病进展的恐惧很常见,这会导致较高的心理发病率。然而,亚洲在这方面的研究受到缺乏经过验证的测量工具的限制。在众多可用的工具中,进展恐惧问卷(Fear of Progression Questionnaire)具有较高的质量评级,这在其选择中是一个重要考虑因素。本研究开发了进展恐惧问卷-简化简体中文版(Fear of Progression Questionnaire - Short Form,FoP-Q-SF),并验证了英语和简体中文版在中文人群中的适用性。
通过正向-反向翻译,重点关注概念和文化等效性,将简化简体中文版翻译成中文。癌症幸存者(N=341)完成了一份自我报告问卷,即进展恐惧问卷-简化简体中文版、其他进展恐惧测量、抑郁、焦虑和生活质量。评估了信度和效标效度,并通过验证性因素分析复制了因子结构。
进展恐惧问卷-简化简体中文版表现出较高的内部和重测信度。效标效度也通过收敛、同时和判别效度得到证明。该因子结构得到支持和复制。原始模型的拟合优度指数表明存在一些不拟合,可以通过在误差协方差矩阵中释放五个参数来充分解决,而不会改变单因素结构。
进展恐惧问卷-简化简体中文版是一种可靠且有效的进展恐惧测量工具,适用于新加坡的混合癌症幸存者人群。该问卷的简化简体中文版将在亚洲其他地区和西方的中国移民中有用,进一步扩展了该问卷的使用。
