An Adaptation, Extension and Pre-Testing of an Interactive Decision Aid for Men Diagnosed with Localized Prostate Cancer in Iceland: A Mixed-Method Study.

In this study an interactive decision aid (DA) for men diagnosed with localized prostate cancer was adapted, extended and pre-tested. The DA's prototype was based on a literature review and other empirically tested DAs. Semi-structured interviews with 12 men (age 65-80) diagnosed with localized prostate cancer were conducted to get feedback on content, usability, and the DA's layout. The interviews were analyzed using thematic analysis and themes were identified using deductive and inductive coding. Participants found the accessibility of the information and the explicit values clarification tool helpful. Four themes were identified: (1) usability and design, (2) content and knowledge, (3) deciding factors of decision-making, and (4) social support. Participants valued receiving extensive and realistic information on surgery/radiation therapy side effects and getting unbiased presentations of treatment options. Following the thematic analysis, the DA was revised and tested in a survey among 11 newly diagnosed prostate cancer patients (age 60-74). The participants valued the DA and found it helpful when making a treatment decision, and all reported that they would recommend it to others making a prostate cancer treatment decision. The DA is currently being tested in a randomized clinical trial (RCT). This is the first DA developed for prostate cancer patients in Iceland and if the results of the RCT show that it is more effective than standard care in assisting newly diagnosed patients with their treatment decision, the DA can be easily translated and adapted to cultures similar to Iceland such as the Nordic countries.

[Views of Icelandic women towards genetic counseling - and testing of BRCA2 mutations].

Introduction The aim of this study was to explore the attitudes of Icelandic women towards existing genetic information, genetic counseling and genetic testing for BRCA mutations which dramatically increase risk for aggressive cancers. Materials and methods Women attending the cancer prevention clinic in Reykjavik, capital of Iceland, from October 12th until November 20th 2015 received an invitation to participate. Participation involved answering a short online questionnaire about background, family history of cancer as well as attitudes towards genetic counseling, BRCA testing and preventive use of such information. Descriptive statistics and chi-square tests were used to describe differences in attitudes towards those questions between subgroups of women. Results 1129 women (69% response rate) answered the questionnaire. Mean age was 47 years (span 21-76 years). Around half (47%) had heard fairly much about the mutations. Independent of family history of cancer, the majority of women were positive towards receiving genetic counseling (79%) and to undergo genetic testing (83%) for BRCA mutation with younger women being more interested than older women. On the other hand, only 4% of the women had already received genetic counseling and 7% undergone genetic testing. Women with family history of cancer were more knowledgeable about BRCA mutations (p<0.0001) and were less afraid of the consequence of being a mutation carrier (p<0.0001) compared to those with little or no family history. Regardless of family history, half (49%) worried that results from genetic testing could influence their health insurance. Almost all, or 97% of the women, were positive or very positive toward using existing genetic information obtained through scientific work, to inform affected indi-viduals of their mutation status. Conclusion Icelandic women are positive towards genetic counseling and testing for BRCA mutations although half of them worry that a positive result might affect their health insurance. Nevertheless, almost all women believe that existing genetic information should be used to inform carriers for preventive purposes.
