Summary

The revised Personal Style Inventory (PSI) effectively measures sociotropy and autonomy, personality traits linked to depression vulnerability. Factor analysis confirmed its structure, with subscale modifications improving fit for clinical and nonclinical groups.

Area of Science:

  • Psychology
  • Clinical Psychology
  • Personality Psychology

Background:

  • Sociotropy and autonomy are personality dimensions associated with depression vulnerability.
  • The Personal Style Inventory (PSI) was developed to assess these traits.
  • Understanding these dimensions is crucial for depression onset, maintenance, and recurrence.

Purpose of the Study:

  • To validate the revised Personal Style Inventory (PSI).
  • To test the theoretical structure of sociotropy and autonomy dimensions using confirmatory factor analysis.
  • To assess the PSI's measurement properties in both nonclinical and major depression outpatient samples.

Main Methods:

  • Confirmatory factor analysis (CFA) was employed to evaluate the PSI's theoretical structure.

Related Experiment Videos

  • The study utilized a large nonclinical sample (n=869) and a clinical sample of outpatients with major depression (n=101).
  • Item and subscale factor structures were analyzed for representation of the theoretical model.

    • Main Results:

    • The PSI's factor structures, both at the item and subscale levels, generally represented the theoretical model well.
    • Modifications to the subscale level were necessary to achieve adequate model fit for both nonclinical and clinical participants.
    • The findings support the PSI's utility in measuring sociotropy and autonomy.

    Conclusions:

    • The revised PSI demonstrates a fair to good representation of the theoretical model for sociotropy and autonomy.
    • Subscale modifications enhance the PSI's applicability and accuracy in diverse populations.
    • The study contributes to the measurement and theoretical understanding of sociotropy, autonomy, and their relation to depression.
