Abstract

Objective: 5-point test (5PT) is a widely used measure for executive abilities that is considered a nonverbal analog for verbal fluency test. The aim of this study is to analyze normative data of 5PT in a representative sample of adults in Estonia. Method: The sample includes 421 subjects (233 women, 188 men) with mean age of 53.1 years (range 19–93) and mean education of 13.6 school years (range 4–24 years). All subjects were healthy with no reported neurologic or psychiatric complications. Subjects were presented a sheet with 5-point matrices and the task was to create as many different figures as possible in a 3 minute period using straight lines. Performance was scored by the number of different solutions generated. In addition two types of errors were also registered: perseverations (repeating previous figures) and configuration errors (drawing figures outside the 5-point matrix). Results: The effect of demographic variables was assessed with multiple regression: F(3, 416) = 88.06, p < .0000001. Age, t(416) = −11.8, p < .0000001, education, t(416) = 6.4, p < .0000001, and sex, t(416) = 2.5, p < .01, had significant effect on the number of different figures. About half of the subjects made perseverative errors (mostly only 1–2 perseverations). Configuration errors were very rare, only 14 subjects made such an error. Conclusion(s): 5PT is a useful measure of executive skills. It helps to estimate the speed and flexibility of generating novel solutions, and the ability to follow rules and monitor performance. Age, education, and sex effects should be considered when using 5PT in clinical assessment.
