Email: Maria.Feijoo@uab.cat Funding informaton This study was supported by the research grant “Women partcipaton in decisions and strategies on early detecton of breast cancer” (PI14/00113) from the Insttuto de Salud Carlos III and cofunded by Fondo Europeo de Desarrollo Regional (FEDER) “Una manera de hacer Europa”. This qualitatve study evaluates a decision aid that includes the benefts and harms of breast cancer screening and analyses women’s percepton of the informaton received and healthcare professionals’ perceptons of the convenience of providing it. Seven focus groups of women aged 40–69 years (n = 39) and two groups of healthcare professionals (n = 23) were conducted in Catalonia and the Canary Islands. The focus groups consisted of guided discussions regarding decision-making about breast cancer screening, and ac- ceptability and feasibility of the decision aid. A content analysis was performed. Women positvely value receiving informaton regarding the benefts and harms of breast cancer screening. Several women had difcultes understanding some concepts, especially those regarding overdiagnosis. Women preferred to share the decisions on screening with healthcare professionals. The professionals noted the lack of inclusion of some harms and benefts in the decision aid, and proposed improving the clarity of the statstcal informa- ton. The informaton on overdiagnosis generates confusion among women and contro- versy among professionals. Faced with the new informaton presented by the decision aid, the majority of women prefer shared decision-making; however, its feasibility might be limited by a lack of knowledge and attudes of rejecton from healthcare professionals.
