In today’s investigation, tall category consequences was in fact seen both for raw and you can ages-corrected DERS complete results (come across Table 1), hence informed me more or less forty five% of DERS overall rating variance
e., p < .01), with Pearson r values of .66, .41, .33, .35, and .60 (all p s < .005) for the correlations between the DERS total score and Negative Urgency, Lack of Premeditation, Lack of Perseverance, Sensation Seeking, and Positive Urgency, respectively. No significant differences were observed among the three groups in the r values for the correlations between the DERS total score, and Negative Urgency, ? 2 (2) = 1.21, p > .50, Lack of Premeditation, ? 2 (2) = 0.25, p > .80, Lack of Perseverance, ? 2 (2) = 0.79, p > .50, Sensation Seeking, ? 2 (2) = 1.79, p > .40, and Positive Urgency, ? 2 (2) = 0.45, p > .50. According to the Box M test, the variance-covariance matrices of the UPPS-P scales were homogeneous across the three groups, M = , F = 1.09, p > .30. According to the hierarchical regression model, the hypothesis of slope parallelism across the three groups for the participants’ age effect on the UPPS-P scales could not be rejected, min. R 2 alter = .00 (Lack of Premeditation), max. R 2 change = .02 (Lack of Perseverance), all p s > .50. Results of the Two-way MANCOVA did not show any significant effect of participants’ age, Pillai V = .08, p > .40, or gender, Pillai V = .12, p > .20, on the five UPPS-P scale scores; the gender-by-group interaction was also not significant, Pillai V = .20, p > .20. Rather, a significant multivariate group effect on the UPPS-P scale scores was observed, Pillai V = .48, p < .001. Raw mean scores and SD s for the UPPS-P scales in the high-BPD, average-BPD, and low-BPD groups, respectively, as well as univariate F tests and ? 2 values, are listed in Table 1. The nominal significance level (i.e., p < .05) of each F test was corrected according to the Bonferroni procedure and set at p < .01; according to univariate F tests based on one-way ANOVAs, significant group effects could be observed only for Negative Urgency and Positive Urgency scales; overall group differences accounted for roughly 40% and 50% of the variance in Negative Urgency and Positive Urgency scale scores, respectively.
Raw and age-adjusted mean scores and SD s for the DERS in the three groups are listed in Table 1. DERS total score variance was homogeneous across the three groups, Levene’s F (2, 88) = 2.08, p > .10; hierarchical regression models did not reveal any significant group-by-age interaction in the relationship between the DERS total score and participants’ age, thus supporting the hypothesis of slope parallelism across the three groups. The two-way ANCOVA results showed a significant and substantial group effect on the DERS total score, F (2, 84) = , p < .001, ? 2 = .46, with no significant effect of participants' gender, F (1, 84) = 0.04, p > .80, ? 2 = .00, or group-by-gender interaction, F (2, 84) = 1.97, p > .80, ? 2 = .05. 64, p < .05, ? 2 = .06.
However, a serious, albeit poor aftereffect of participants’ ages with the DERS overall score are observed, F (1, 8cuatro) = 4
Thus, six Bonferroni contrasts were computed in order to test the significance of the differences in mean scores on Negative Urgency, Positive Urgency, and DERS total scores between the high-BPD group and both the average-BPD and low-BPD groups, respectively. The nominal significance level (i interracial dating central support.e., p < .05) of each contrast was corrected according to the Bonferroni procedure and set at p < .0083. Scores on both the Negative Urgency and Positive Urgency scales significantly discriminated the high-BPD group from both the low-BPD and average-BPD groups (see Table 1). Interestingly, the between group differences in Positive Urgency remained significant even when controlling for the variance associated with Negative Urgency, F (2, 87) = 5.78, p < .005, ? 2 = .14, with the high-BPD group evidencing significantly higher Positive Urgency mean scores than both the low-BPD group, Bonferroni t = 3.40, p < .005, d = 0.88, and average-BPD group, Bonferroni t = 2.29, p < .025, d = 0.59. Conversely, the between group differences in Negative Urgency did not remain significant when controlling for the variance associated with Positive Urgency, F (2, 87) = 1.50, p > .20, ? 2 = .04.
