Summary
This study assessed the Ruff Figural Fluency Test
Area of Science:
- Neuropsychology
- Cognitive Assessment
Background:
- The Ruff Figural Fluency Test (RFFT) is a cognitive assessment tool.
- Evaluating the interrater reliability of the RFFT is crucial for its consistent application.
Purpose of the Study:
- To examine the interrater reliability of the Ruff Figural Fluency Test (RFFT).
- To investigate scoring accuracy improvements with practice.
- To determine if RFFT performance correlates with scoring accuracy.
Main Methods:
- 124 college students completed the RFFT and scored multiple test protocols.
- Interrater reliability was calculated for unique designs, design perseverations, and error ratios.
- Scoring accuracy was analyzed in relation to practice and RFFT performance.
Main Results:
- High interrater reliability was found for unique designs (.93).
- Moderate reliability was observed for design perseverations (.74) and error ratios (.66).
- Participants demonstrated improved scoring accuracy with practice, and better RFFT performance correlated with higher scoring accuracy.
Conclusions:
- The RFFT demonstrates good to excellent interrater reliability, particularly for unique designs.
- Practice enhances scoring accuracy for the RFFT.
- Individuals with higher RFFT performance tend to be more accurate raters, suggesting a link between cognitive ability and scoring proficiency.
