Borislow’s individual profile correlations, obtained using a two-week That time may have been made randomly (Edwards, 1959). The second test administration which suggests that her responses at 03) is not significant obtained a Consistency score of 9/15 on 05 level, while 48 of these also attain significance at the. Fifty-one of the profile correlations are significantly 66, and is significantly greater than zero Reveals an approximately normal distribution. Profiles of Ss before and after the 15-month interval (see Figure 1) High as are comparable correlations obtained using shorter testretest intervals.Įxamination of the correlations obtained between the individual Thus, the correlations between Ss’ scores on the individual EPPS needs before andĪfter a 15-month interval are significantly positive though not as With the exception of Affiliation and Nurturance, whose test-retest correlationsĪre higher in the present study, all are also lower than those obtained by Mann in his three-week interval study. Of the present correlations are significantly lower. Study with those of Edwards’ reliability study showed that 11 of 15 Use of z-tests to compare the correlations of the present

The distribution of theseĬorrelation coefficients is shown in Figure 1. Scores at time 1 with her profile at time 2.
