Aim: The study was conducted to adapt the Questionnaire of Tendency to Breast Reconstruction after Mastectomy to Turkish and evaluate its cultural adaptation, validity, and reliability.

Material and Method: This methodological study was conducted through face-to-face interviews with patients who underwent mastectomy surgery in two hospitals in Erzurum Province. The study population consisted of the patients who underwent a mastectomy in the relevant hospitals between April 2016 and September 2018 and had at least six months after surgery. The study sample consisted of 118 patients who met the inclusion criteria in the specified population and agreed to participate in the study between these dates. “Personal Information Form” and “Questionnaire of Tendency to Breast Reconstruction after Mastectomy” were used to collect data. Language, content and construct validity and internal consistency reliability, and test-retest reliability were evaluated to determine whether the questionnaire is a valid and reliable measurement tool.

Results: Firstly, the language validity of the questionnaire was provided through translation- back translation, and then its content validity was provided by making the necessary corrections in accordance with expert opinions. As a result of the exploratory factor analysis, it was determined that the questionnaire showed a four-factor structure, and the factor loadings of all items were over 0.40 and within the appropriate range. The Cronbach’s alpha coefficient of the questionnaire was found to be 0.84 for the overall questionnaire, 0.83 for the main factors subscale, 0.82 for the second factors subscale, 0.63 for minor barriers subscale, and 0.82 for factors causing fear subscale.

Conclusion: The study results indicated that the questionnaire has a similar structure to the original version and can be used in Turkey. The questionnaire was considered a valid and reliable tool.
