The aim of this study is to explore the construct validity of the Body Image Scale for Cancer Questionnaire (BIS) using cognitive interviews.
Twelve breast cancer survivors participated in a cognitive interview while completing the BIS. Each participant was asked to think-out-loud while answering items, and an interviewer asked probing questions relating to the participants' comprehension, example retrieval, certainty of answer and other decision-making factors. Interviews were audio recorded and transcribed, and the data were analysed deductively and inductively.
The participants' interpretations of the questions varied significantly. Several participants perceived the phrasing of some questions to be leading. The participants were able to provide examples of how their physical, physiological and body function affected their body image. The participants expressed positive attitudes towards, and gratitude for their body, which was not captured by the questionnaire. At times, the participants felt uncertain in how to respond appropriately to specific items, and the participants found some items challenging to answer. Finally, the BIS included sensitive questions that elicited emotional reactions and discomfort for some participants.
The findings of this study provide insight into, and suggestions for potential questionnaire revisions that may enhance the validity and relevance of the BIS for use with breast cancer survivors.
本研究旨在通过认知访谈探讨癌症问卷体像量表（BIS）的结构效度。
12 名乳腺癌幸存者在完成 BIS 时参加了认知访谈。要求每位参与者在回答项目时大声思考，并由访谈者询问与参与者的理解、示例检索、答案确定性和其他决策因素有关的探究性问题。对访谈进行了录音和转录，并对数据进行了演绎和归纳分析。
参与者对问题的解释差异很大。一些参与者认为一些问题的措辞具有引导性。参与者能够提供他们的身体、生理和身体功能如何影响他们的体像的例子。参与者对自己的身体持积极的态度，并表示感激，而这些在问卷中并未体现。有时，参与者对如何恰当地回答特定项目感到不确定，并且一些参与者发现某些项目难以回答。最后，BIS 包含一些敏感问题，这些问题会引起一些参与者的情绪反应和不适。
本研究的结果深入了解了 BIS 可能需要进行的潜在修订，以增强其对乳腺癌幸存者的有效性和相关性。
