- Examination of inter-trial reliability and relations among parameters of the successive choice reaction test using extremities
It is imperative to evaluate the ability to perform tumble avoidance actions, including stepping and putting one's hand out quickly. This study aimed to examine the inter-trial reliability and relations among parameters of the successive choice reaction test using extremities. The sample comprised 30 young men. They were required to touch or step quickly from a standing posture onto the seat located on the table before them in response to instructions given on a omputer screen. The instruction tempo was 40bpm. Three patterns of instruction included combined patterns using one's right and left hands as well as one's right and left feet three times. Three trials were conducted for each of the patterns. The sum of the sixtouch and six-step reaction time was used as an evaluation variable, namely, choice reaction time in one trial. The repeated measure results of one-way ANOVA revealed significant differences among the means of the three trials in each pattern. Hence, the intra-class correlation coefficient (ICC) between two approximate values with no significant differences was found in the three trials, with an ICC of 0.90 or more. Employing the mean of two approximate values as the representative value, the correlation coefficient (r) among the times of the three patterns and the total time of the three patterns (a total scale) was calculated. The results revealed r was 0.70 or more among the patterns and 0.9 or more between the total scale and each pattern. In conclusion, the reliability of the newly developed continuous successive choice reaction test was high in the three patterns. Moreover, the relations among the three patterns were high. The three patterns also had a high relation with the total scale. Therefore, it may be concluded that the three patterns measure the same ability.
