The reliability and convergent and divergent validity of the Ruff Figural Fluency Test in healthy young adults.

چکیده
The reliability and validity of standard and qualitative scores for the Ruff Figural Fluency Test (RFFT; Ruff, 1988) was examined in 102 healthy undergraduates. Participants (M age = 21.79; SD = 3.7; age = 80% Caucasian) were administered the RFFT and measures assessing executive functions (EF) and other cognitive domains. Inter-scorer reliability was excellent (0.9 range) for most RFFT indices. Test-retest coefficients (M interval = 7 weeks) ranged from 0.64 for the error ratio score to 0.87 for unique designs. RFFT indices correlated with Block Design performance and nonverbal measures of working memory, but were unrelated to measures of verbal fluency, verbal learning, or working memory for verbal material. RFFT novel design output correlated with most measures of EF supporting the convergent validity of this measure. In contrast, correlations between measures of EF and qualitative scores were absent or weak. RFFT score interpretation is discussed in light of relevant models of EF and directions for future research are presented.
