Specificity of interpersonal sensitivity to non-melancholic depression

Scores of 69 remitted depressed patients were compared to control subjects on the Interpersonal Sensitivity Measure (IPSM). The patients were categorised into melancholic and non-melancholic sub-groups according to DSM-III criteria. Differences between the depressives and controls were detected but were principally the result of high IPSM scores being returned by the non-melancholic depressives. Melancholic depressives did not differ from the controls in their IPSM scores, supporting the proposition that this depressive sub-type is not associated with a vulnerable personality style.
