Studying Self-Fragmentation From Kohut’s Self Psychology Perspective

The main goal of the current study was to empirically study one of the central constructs in Kohut’s self-psychology—self-fragmentation. For this purpose, we constructed a new self-report scale (the Fragmented Self Inventory [FSI]) tapping fragmentations along each of the two major axes of the self—grandiosity and idealization. Across six independent samples, findings provided solid evidence on the reliability and two-factor structure of the scale. In addition, FSI scores were associated with existing scales tapping disorders of the self, self-confusion, frustration of self-object needs, pathological forms of narcissism, interpersonal difficulties, dissociative states, and impoverished mental health. Moreover, the findings of Studies 4–6 provided initial support for the incremental validity of the new scale. FSI scores made a unique contribution to pathological narcissism, mental dissociation, and mental health problems beyond the significant contribution made by existing scales. Findings were discussed from the perspective of Kohut self-psychology.
