Assessing pathology in the separation-individuation process by an inventory. A preliminary report

Area of Science:

• Developmental Psychology
• Clinical Psychology
• Psychopathology

Background:

• Growing evidence links early separation-individuation disturbances to adult psychopathology.
• Borderline personality disorder (BPD) is a key condition associated with these developmental disruptions.
• Clinical observations have described manifestations of these disturbances in adulthood.

Purpose of the Study:

• To develop and validate an inventory assessing adult manifestations of separation-individuation disturbances.
• To determine if the inventory can differentiate individuals with BPD from a control group.
• To provide a quantitative measure for pathological outcomes of early developmental processes.

Main Methods:

• Development of a novel inventory based on established clinical theories of separation-individuation.
• Administering the inventory to subjects meeting DSM-III criteria for BPD.
• Comparing inventory scores between the BPD group and a random university employee control group.

Main Results:

• Subjects with borderline personality disorder (BPD) achieved significantly higher scores on the separation-individuation disturbance inventory compared to the control group.
• Preliminary data suggest the inventory is a promising tool for assessing adult psychopathology related to this developmental phase.
• The findings support the hypothesis linking early developmental issues to adult personality disorders.

Conclusions:

• The developed inventory shows preliminary validity in assessing adult manifestations of separation-individuation process pathology.
• The study supports the connection between early developmental disturbances and adult borderline personality disorder.
• Further research is recommended to establish the inventory's full psychometric properties and refine scoring.
