A college laboratory was used as the setting to test the reliability and validity of a newly designed Breast Self-Examination Proficiency Rating Instrument (BSEPRI). The instrument was tested on two groups of nursing students, one instructed prior to testing and one not. BSE proficiency was scored individually for each subject as she demonstrated the procedure on a breast simulation model. Independent sample t tests were used to compare the groups. Mean scores of the instructed group were significantly higher than mean scores of the uninstructed group on the total test and on subscales of palpation and inspection. Criterion-referenced concurrent validity was assessed by correlating palpation scores with lump detection in a silicone model. Interrater reliability using percentage agreement between raters was high on 19 out of 23 criteria. Kuder-Richardson internal reliability coefficients ranged from .67 to .74.
