Binge and purge processes in bulimia nervosa: a qualitative investigation.

This study explored the nature and functions of the binge and purge processes of those who suffer from bulimia nervosa. Using a qualitative research design, the researchers conducted semi-structured interviews with eight affected women, asking them to discuss their bingeing and purging experiences. Use of an emergent data analysis method revealed participants behaviors as attempts to cope and control, to improve self-regard and social status, to regulate emotion, and to provide physiological reinforcement. Implications of the findings for clinical practice are discussed.
