Classification
Exploratory: Unruptured Cerebral Aneurysms and Subarachnoid Hemorrhage (SAH)
Short Description of Instrument
Description: The paper-and-pencil form of the 5-Point Test (5-PT) is a widely used test of brain functioning. The test makes demands on different neuropsychological domains – planning, cognitive flexibility and divergent thinking. The 5-PT’s usefulness as a clinical test has been demonstrated for both neurological and psychiatric disorders. The influence of different demographic variables has been discussed in the literature. In particular, age and education level appear to affect performance on the 5-PT. The present test is based on proven experimental paradigms for measuring divergent thinking as an aspect of the executive functions. It can be used to assess neuropsychological deficits and prepare for therapeutic intervention.
Comments/Special Instructions
In the 5-PT the participant is given sheets of paper on which 40 squares, each consisting of a fixed pattern of five symmetrically arranged dots, are printed. The participant is asked to produce as many different designs as possible by connecting the dots in each square with one or more straight lines within two minutes. The participant is given the following instructions:
 
“There are a number of squares, each containing five dots, on the sheet of paper in front of you. I want you to draw as many designs as possible within the next two minutes by connecting two or more dots with straight lines. Not all dots per square have to be used. Please do not repeat any designs or draw lines that do not connect dots.”
 
After the demonstration of two possible designs by the examiner, the participant is asked to begin with the task. Repetitions of designs (perseverative errors) and production of designs with lines that failed to connect dots (rule violations) are regarded as errors. The number of unique designs and the number of both perseverative errors and rule violations are scored for each minute.
Scoring
The main variables describe the total number of patterns produced, the number of correct patterns and perseveration errors. The number of strategies used, the error rate and the percentage of correctly worked items are also reported.
Rationale/Justification
The 5-PT tests a number of neuropsychological domains that are regarded at risk in patients following SAH. Due to a recent publication by Tucha et al., 2012, normative data is available in n=635 healthy adults up until the age of >69 years, thus covering the age range of SAH patients. For these reasons, the Swiss national standard of neuropsychological assessment after SAH includes the 5-PT.
