Consequences of daily self-weighing: a pilot study in higher-weight women with a history of breast cancer.

Abstract

Self-monitoring weight is commonly recommended for higher-weight women with a history of breast cancer, despite evidence demonstrating potentially negative psychological consequences of frequent self-weighing. The extent to which higher-weight women with breast cancer experience emotional and behavioral consequences in response to daily self-weighing is unknown. In this pilot study, women (n = 51) with a history of breast cancer in a behavioral weight management program completed a weeklong daily diary protocol. Participants were asked to self-weigh every morning and report on subsequent weight-related shame and guilt, and end-of-day engagement in compensatory exercise, diet, and purging behaviors. Women reported higher levels of guilt on days when their body weight was higher than usual, and when there was more discrepancy between their current vs. goal weight. Additionally, women engaged in higher levels of compensatory diet behavior on days when they experienced more weight-related guilt than usual. Based on these preliminary findings, daily self-weighing may be associated with harmful emotional and behavioral consequences among higher-weight women with a history of breast cancer.
