Numbing scale scores in female psychiatric inpatients diagnosed with self-injurious behavior, dissociative identity disorder, and major depression.

Female inpatients engaged in self-injurious behavior (SIB) and females diagnosed with Dissociative Identify Disorder (DID) scored higher on the Glover Numbing Scale (GNS) than female inpatients diagnosed with Major Depressive Disorder (MDD). The DID sample showed a multi-modal distribution of scores, and the MDD sample showed a bimodal distribution with a significant difference between the means of the two subgroups. An additional subsample of outpatient males diagnosed with MDD also evidenced a bimodal distribution of scores with a similar spread between the two means. Scores on the Beck Depression Inventory did not discriminate the latter two subgroups.

Vulnerability Scale scores in female inpatients diagnosed with self-injurious behaviour, dissociative identity disorder, and major depression.

For three groups of predominantly female inpatients scores on the Glover Vulnerability Scale were compared with each other and with those of a control sample. The four groups included individuals who were diagnosed with self-injurious behavior, females diagnosed with Dissociative Identity Disorder, females whose predominant diagnosis was Major Depressive Disorder, and female controls. Females with a trauma-related diagnosis (Groups 1 and 2) scored higher on the Glover Vulnerability Scale than Group 3. History of exposure to trauma or childhood abuse most clearly discriminated higher scores within the control sample. The findings highlighted the close relationship between histories of exposure to trauma and high scores on this scale. Additional analysis of these scores and those on the Glover Numbing Scale showed a close association between feelings of vulnerability and the numbing response.
