A new approach to clustering eating disorder patients: assessing external validity
and comparisons with DSM-IV diagnoses
A new approach to clustering eating disorder patients: assessing external validity
and comparisons with DSM-IV diagnoses
Introduction: This study assessed the external validity of four statistically distinct clusters identified in a
sample of eating disorder patients, derived from eating disorder features, attachment and coping styles. It
also compared clusters with DSM-IV diagnoses.
Methods: Eating disorder psychopathology, attachment, coping, mood, health status and general functioning
were measured in 165 patients.
Results: The ‘mild eating disorder group’ reported significantly lower levels of functional impairment
compared with the ‘insecure generalised eating disorder’ group, and significantly higher levels of social
functioning, vitality and general mental health compared with the ‘passive/avoidant restrictors’ and
‘insecure generalised eating disorder’ groups. These latter groups reported significantly higher levels of
depression compared with the ‘bulimic’ and ‘mild eating disorder’ groups. Compared with DSM-IV diagnoses,
clusters were more clearly differentiated on a wide range of features, including mood and health status as
well as eating disorder features, attachment and coping.
Conclusions: Findings provide preliminary support for the external validity of the clusters. Future research
might extend this work by investigating the clusters in relation to recovery, relapse and treatment response.

Abstract
Introduction: This study assessed the external validity of four statistically distinct clusters identified in a
sample of eating disorder patients, derived from eating disorder features, attachment and coping styles. It
also compared clusters with DSM-IV diagnoses.
Methods: Eating disorder psychopathology, attachment, coping, mood, health status and general functioning
were measured in 165 patients.
Results: The ‘mild eating disorder group’ reported significantly lower levels of functional impairment
compared with the ‘insecure generalised eating disorder’ group, and significantly higher levels of social
functioning, vitality and general mental health compared with the ‘passive/avoidant restrictors’ and
‘insecure generalised eating disorder’ groups. These latter groups reported significantly higher levels of
depression compared with the ‘bulimic’ and ‘mild eating disorder’ groups. Compared with DSM-IV diagnoses,
clusters were more clearly differentiated on a wide range of features, including mood and health status as
well as eating disorder features, attachment and coping.
Conclusions: Findings provide preliminary support for the external validity of the clusters. Future research
might extend this work by investigating the clusters in relation to recovery, relapse and treatment response.
