Translation and cultural adaption of the decisions module for colorectal cancer screening into a Swedish version – the SCREESCO questionnaire

Abstract

Objectives: Colorectal cancer (CRC) is suitable for population screening due to its high incidence and the recognizable and treatable prephase, and the present study is part of the larger study; Screening for Swedish Colons (SCREESCO). In Sweden, there is, to our knowledge, no questionnaire assessing shared decision making (SDM) with regard to CRC screening and, therefore, the aim of the study was to translate and culturally adapt the CRC screening module of the National Survey of Medical Decisions (DECISIONS) into a Swedish context.

Material and methods: A qualitative design inspired by guidelines based on methods for cross-cultural adaptation of questionnaires was used. In addition, focus group discussions, individual interviews and think-aloud (TA) sessions were performed.

Results: Of the 54 items included in the original DECISION survey, 32 were excluded, 22 were modified, and three were added as a result of the qualitative study. How the health care organization communicated and CRC screening knowledge was communicated were found to be the most important cultural differences between Sweden and the USA. The final questionnaire consists of 24 items.

Conclusion: The process of translation and cultural adaptation of the CRC screening module of the DECISIONS survey resulted in the removal and modifying of a considerable number of items. The major rationale for the removal and modifying of items can be explained by the different cultural traditions between Sweden and the USA when communicating with the health care system regarding screening participation and how CRC screening information and knowledge is communicated.
