Objective:

To adapt and validate the Five-Factor Obsessive–Compulsive Inventory–Short Form (FFOCI-SF) for use in a Swedish adult population, including individuals with and without eating disorder psychopathology.

Approach:

• Participants and Procedure: Participants were recruited online in Sweden through various channels, including social media and psychiatric clinics. A total of 395 individuals completed the questionnaire battery, with 152 in the eating disorder group and 243 in the non-clinical comparison …
• Measures: The FFOCI-SF, a 48-item instrument assessing 12 maladaptive personality facets related to OCPD, was utilized alongside other established measures.

Key Findings:

• The study evaluated item-level properties and internal consistency of the FFOCI-SF.
• The hypothesized 12-factor structure was tested for empirical refinements.
• Measurement invariance across eating disorder and non-clinical groups was assessed.
• Group differences in FFOCI-SF scores were compared at both latent and observed-score levels.
• Intercorrelations among the facets and convergent and discriminant validity were examined.

Interpretation:

The study addresses the lack of a validated Swedish measure for OCPD traits, particularly in populations with eating disorders.

Limitations:

• The study's sample may not fully represent the broader Swedish population.
• The reliance on self-reported measures may introduce bias.

Conclusion:

The adaptation and validation of the FFOCI-SF for Swedish populations is necessary for accurate assessment of OCPD traits.
