- To explore the heterogeneity within eating disorders concerning personality, eating behaviors, and emotional expression.
- To evaluate recent research supporting distinct subgroups within the eating disorder spectrum.
Summary:
- The paper reviews literature attempting to define eating disorder subgroups, considering variations in personality, eating behaviors, and emotional expression.
- Current research, informed by the DSM-II-R, reinforces the distinction between patients with restrictive eating patterns and those experiencing bulimic episodes.
- This differentiation is supported by observed differences in clinical presentation and underlying psychological factors.
Impact:
