The specific value of the factor was 6.901 which predicted 86.262 percent of variance.Cronbach’s Alpha was calculated 0.890. Inter-rater reliability shows that the correlation between grades twice collected by the two raters, was significant and high (p˂0/0001, r=0/714). The test-retest correlation, was significant and high(p˂0/0001, r=0/876).
