title: The Toronto Breast Self-Examination Instrument (TBSEI): its development and reliability and validity data.
abstract: The Toronto Breast Self-Examination Instrument (TBSEI) was developed out of the need for a self-administered survey that is reliable and valid. This article describes the development of the TBSEI, its dimensions, and reliability and validity data to support its continued use. To analyze the reliability and validity properties of the three TBSEI scales, we surveyed 729 Toronto, Ontario women. The TBSEI was found to have good face and content validity, internal consistency reliability (0.91, 0.69, 0.85), and test-retest reliability (0.89). Age norms for each of the three scales are also provided. These results are consistent with previous research findings in breast cancer and breast self-examination research.
