Florida Obsessive-Compulsive Inventory and Children's Florida Obsessive Compulsive Inventory: A reliability...

Area of Science:

• Psychometrics
• Clinical Psychology
• Neuroscience

Background:

• The Florida Obsessive Compulsive Inventory (FOCI) and its pediatric version (C-FOCI) are utilized for assessing obsessive-compulsive disorder (OCD) symptoms.
• Reliability generalization meta-analysis is crucial for evaluating the consistency of these measurement tools across diverse studies.

Approach:

• A reliability generalization meta-analysis was performed on 23 independent samples for the FOCI and 20 for the C-FOCI.
• Kuder-Richardson 20 (KR-20) and Cronbach's alpha were employed to calculate average reliability coefficients.
• Moderator analyses investigated factors influencing score heterogeneity, including coefficient source, study focus, and sample size.

Key Points:

• The FOCI Symptom Checklist yielded an average KR-20 of 0.826, and Symptom Severity an average alpha of 0.882.
• The C-FOCI Symptom Checklist showed an average KR-20 of 0.740, and Symptom Severity an average alpha of 0.794.
• Study characteristics like coefficient source, study focus, and sample size influenced reliability estimates.

Conclusions:

• The FOCI and C-FOCI exhibit strong reliability, supporting their use in clinical practice.
• Their brevity and ease of administration make them effective tools for OCD screening.
• These findings underscore the utility of the FOCI and C-FOCI in both research and clinical settings for evaluating obsessive-compulsive symptomatology.
