Original tests for information processing speed: Normative data for greek population and clinical utility
Summary:
Information Processing Speed is defined as the time required for the successful completion of a mental task.
The purpose of this study was to standardize newly constructed tests, which assess the Information Processing Speed (IPS) as well as highlight their clinical utility.
Method. This survey involved 240 healthy participants and 33 patients with RRMS multiple sclerosis. The psychometric properties of the tests as well as their reliability and validity were tested. Raw values were distributed in norms and additional regression-based norms. Tests of anxiety, depression, overall cognitive ability, and subjective complaints of memory and attention were administered to the healthy participants to control for any effects of the aforementioned upon performance in tests. A between-subjects comparison was also made between patients and healthy controls.
Results. The Read & Visual Search tests demonstrated very good psychometric properties. Participant age influenced performance in both tests, while the educational level affected performance only in the Visual Search test. Moreover, in the Visual Search test, the overall cognitive ability and subjective complaints of attention and memory had a small effect. On the other hand, healthy controls, compared to patients, performed significantly better in both trials. The Read test found a similar performance pattern in the 16 to 49 and 50 to 70 years age groups. The Visual Search test exhibited a similar performance pattern for the 16 to 49, 50 to 69, and 70 to 80+ age groups, whereas statistically significant differences were identified in all three main education categories (9 years, 10 to 12 years, and 13+ years of education). Also, regression-based norms were created for clinical and research purposes. Stress and depression levels did not influence performance, whilst overall cognitive ability and the presence of subjective complaints regarding attention and memory problems had a small effect on the second test.
Conclusion. Our study showed that these original tests present good variability and reliability for assessing Information Processing Speed (IPS). The clinical usefulness of IPS tests was highlighted through the comparison of healthy individuals with patients diagnosed with RRMS multiple sclerosis.
