The scale consists of a total of 13 items to determine breast cancer awareness, including symptoms (11 items), frequency of breast examination (1 item) and breast cancer age (1 item).

Incorrect answers are worth 0 points. Scoring is between 0-3. Cronbach's alpha value of the scale was found to be 0.89. As the score obtained from the scale increases, breast cancer awareness increases (Baş and Ursavaş, 2022).

The alpha value of the general knowledge dimension was .60; The alpha value of the treatability subscale was found to be .62 and the total of the scale was found to be .71 (Stager, 1993). The scale was adapted to Turkish by Başak (2015). Başak is the sub-dimension and total Cronbach's alpha coefficient of the scale; .65, .50 for General Knowledge, Treatability, and Scale Total scores, respectively. and found .67.
