Breast self-examination palpation skill: A methodological note

Abstract

A current issue in research of breast self-examination (BSE) efficacy is the competency of BSE performance. A nonverbal method for testing two palpation skills were developed. They were designed for mail surveys, or other cost-effective methods of following up subjects in a longitudinal study design. They were also designed to avoid semantics problems associated with verbal descriptions of BSE performance, as noted in earlier research of the author. These pictorial questions were included in three mail surveys of the general female population. The data were consistent across all three surveys for both the verbal and nonverbal questions of palpation skill. The diagram index of the hand part used in BSE suggested that a higher proportion of BSE practicers are using the recommended hand part than their verbal reports would indicate. However, the data from the diagram assessing the amount of pressure used for BSE were not very different from the results of the verbal questions.
