Breast self-examination by young women: II. Characteristics associated with proficiency.

Studying a stratified random sample of university women (n = 869) we investigated the correlates of proficiency (i.e., the correctness or competence) of breast self-examination (BSE). A 19-item BSE quality index score was developed based on the recommended steps a woman should perform when doing the exam in the three BSE positions. A comprehensive set of independent variables including knowledge, attitudes and perceptions, personal characteristics, and environmental factors were studied. While proficiency scores for both undergraduates and graduates were relatively low, the mean score for graduates was significantly higher than for undergraduates. This study corroborates the few recent studies that indicate that frequency of performance is not highly correlated with proficiency (relationships were r = .14 and .04, respectively, for undergraduate and graduate women). Bivariate and multivariate regression analyses demonstrate that the relevance of such factors varies by age (undergraduate and graduate). Results of the regression model indicate that the skill knowledge variable regarding time of month BSE should be performed, awareness of BSE, perceived effect of cancer detection, and perceived benefit of BSE were predictors of more proficient practice for undergraduates. Knowledge of time of month to do BSE and mammogram as a detection technology and discussion of BSE with others were important for graduate women. The independent variables examined accounted for 22 percent and 30 percent of the variance, respectively, for undergraduate and graduate women.(ABSTRACT TRUNCATED AT 250 WORDS)
