items representing feminine traits, and 20 filler items which are considered neutral with respect to common stereotypes. Participants ranked each item on how closely each item related to them individually. The BEM ranked each item on a scale from 1 to 7, with a lower score indicating that the item was never or seldom true, and a higher score indicating the item was often or frequently true.Sandra L. Bem (1974) administered the BSRI to two groups of college students: Stanford and Foothill Junior. She reported an internal consistency reliability coefficient in the Stanford sample (Masculinity a= .86; Femininity a= .80) and Foothill sample (Masculinity a= .86; Femininity a= .82) respectively for the Masculinity- Femininity scale. This constitutes a moderate or high reliability. Furthermore, the Stanford sample wore the BSRI twice, the second with four weeks interval from the first administration. The test- retest reliability revealed coefficients (Masculinity r= .90; Femininity r= .90), which represented a very high liability.On the validity of the studies, methods of Criterion Validity and Convergent Construct Validity were administered in her studies. She obtained the criterion validity by differentiated by the relationship on personality characteristics from masculinity and femininity between the BSRI scale and her criterions. In addition, predicting and correlating with scores on BSRI scale showed its convergent construct validity. Hence, masculinity and femininity are independent variables empirically and logically.The JPI-R, which was developed by D. N. Jackson (1994), is a revision of the original Jackson Personality Inventory. The JPI-R assesses personality variables relevant to the functioning of a person in a wide range of settings such as those involving work, educational/organizational behavior, or interpersonal situations. The JPI-R contains a total of 300 True/False items, representing 15 scales. The JPI-R's 15 s...
