Abstract

The current study evaluated the convergent validity of the PEAK-E short assessment versus the PEAK-E long assessment, to determine if the short form version of the assessment would be just as effective in identifying potential skill deficits as the long form version. This assessment will extend on the current PEAK literature and will indicate in the results the validity between the PEAK-E long assessment and the short assessment. In the current study twenty-four participants were assessed using both the long assessment and the short assessment. The researchers performed both the PEAK-E long assessment and the short assessment with each participant and then a Pearson’s correlation was conducted to determine the convergent validity of the two measures. The results of the current study lend support to the validity of the PEAK-E long and short assessment tool. These results suggest that the PEAK-E short assessment captures many of the same skills and abilities as the long assessment scores, and that the two assessment produce similar results. The results show a strong positive correlation between the PEAK-E short assessment and the PEAK-E long assessment.
