Add to Your Psychopathology Battery to Assess Adult Clients for Personality Difficulties


The IASC is a self-report measure of an individual’s psychological functioning capacity in the areas of forming and maintaining meaningful relationships, creating a stable sense of personal identity and self-awareness, and the ability to modulate and tolerate negative affect. This instrument is particularly useful with adults who have experienced significant childhood abuse or trauma.

Features and benefits

  • Helps to identify targets for treatment, such as identity disturbance and affect regulation problems; predicts potential problems that may arise during psychotherapy; and provides clinical data to corroborate diagnoses, especially those involving dysfunctional personality traits or disorders.
  • May prove useful in the assessment of individuals with potential DSM-IV Axis II or personality-level distress or disorder, as well as those with histories of significant childhood neglect, trauma, or attachment disruption. 
  • May alert clinicians to the possibility of treatment disrupting issues (e.g., abandonment concerns, idealization-devaluation cycles, or excessive suggestibility).
  • The 63 items of the IASC are contained in a reusable item booklet. Respondents complete a separate, carbonless answer sheet that facilitates rapid scoring by hand. Each symptom item is rated according to its frequency of occurrence over the prior 6 months, using a 5-point scale ranging from 1 (Never) to 5 (Very Often).
  • The IASC requires approximately 15 to 20 minutes to complete for all but the most clinically impaired individuals. The IASC can be scored and profiled in approximately 10 minutes.
  • Seven 9-item scales
    • Interpersonal Conflicts (IC)
    • Idealization-Disillusionment (ID)
    • Abandonment Concerns (AC)
    • Identity Impairment (II)
    • Susceptibility to Influence (SI)
    • Affect Dysregulation (AD)
    • Tension Reduction Activities (TRA)
  • Normed on 620 individuals from the general population, making it an ideal component of a comprehensive assessment of adult psychopathology.
