Psychological distress, health beliefs, and frequency of breast self-examination

Although monthly breast self-examination (BSE) is recommended for early breast cancer detection, most women do not comply. Few studies have examined the impact of psychological distress on BSE frequency. Recent research suggests that it may be particularly important to examine the role of distress in the recently identified phenomenon of BSE overperformance (>1/month). One hundred thirty-five healthy women with and without family histories of breast cancer completed sociodemographic, health belief general and cancer-specific psychological distress, and BSE frequency questionnaires. The central finding of the study was that BSE underperformance and overperformance had two distinct sets of predictors: health beliefs, specifically barriers against BSE and low confidence in BSE performance, were related to BSE underperformance, while higher levels of psychological distress, particularly cancer-specific intrusive thoughts, were related to BSE overperformance. Findings underscore the need to evaluate BSE under- and overperformance separately and to develop problem-specific interventions to increase compliance with monthly BSE.
