Background/Description
The Florida Obsessive Compulsive Inventory (FOCI), developed by Wayne K. Goodman in 1994, is a brief self-report screening tool designed to assess the presence and severity of obsessive-compulsive disorder (OCD) symptoms. Published in Psychological Assessment (1994), the FOCI consists of two parts: a 20-item Symptom Checklist (yes/no endorsement of common obsessions/compulsions) and a 5-item Severity Scale rated 0–4 (higher = greater severity). Total scores range from 0–20 (checklist) and 0–20 (severity), often combined or used separately, with a cutoff ≥8 on severity or ≥6 symptoms suggesting OCD.
The FOCI takes ~5 minutes to complete and is used in clinical psychiatry, psychology, and research for rapid OCD screening. Validated with ~100–200 OCD and non-OCD patients (mean age ≈ 18–50 years, mixed gender, U.S.-based), it correlates with the Yale-Brown Obsessive Compulsive Scale (Y-BOCS, r ≈ 0.70–0.85).
Administration, Scoring and Interpretation
- Obtain the FOCI from Goodman (1994) or Psychological Assessment, ensuring ethical permissions.
- Explain to participants (adults 18+ with suspected OCD) that the inventory screens OCD symptoms, emphasizing confidentiality and voluntary participation.
- Administer the 25-item self-report scale in clinical or research settings, with patients endorsing symptoms and rating severity.
- Estimated completion time is ~5 minutes.
- Ensure a supportive environment; provide mental health resources (e.g., referrals) and adapt for accessibility (e.g., large print) if needed.
Reliability and Validity
The FOCI demonstrates strong psychometric properties (Goodman, 1994). Internal consistency is high (Cronbach’s alpha ≈ 0.80–0.90). Test-retest reliability is strong (r ≈ 0.80–0.90 over weeks). Convergent validity is supported by correlations with the Y-BOCS (r ≈ 0.70–0.85). Discriminant validity is evidenced by differentiation from anxiety/depression scales. Sensitivity (80–90%) and specificity (80–90%) are high at cutoffs. The FOCI reliably screens OCD. Pairing with the Y-BOCS or OCI-R enhances comprehensive assessment.
