The latest UPPS-P Natural Choices Level [21, 23] are a 59-product notice-statement measure made to assess five impulsivity-relevant qualities, also Bad Urgency (several points), Shortage of Premeditation (11 circumstances), Lack of Persistence (ten issues), Feelings Seeking to (a dozen products), and you will Self-confident Importance (14 circumstances). Whiteside and you can Lynam learned that the newest UPPS reveals higher level internal texture and convergent validity, and soon after studies have revealed that the latest subscales of UPPS build unique efforts to various conditions (indicating these subscales portray key factors away from impulsivity perhaps not examined various other impulsivity steps; ). In the modern investigation, Cronbach ? thinking on the complete shot was in fact .88, .84, .77, .81, and you may .ninety-five to have Bad Necessity, Shortage of Premeditation, Lack of Efforts, Feeling Trying to, and you will Confident Necessity, respectively. Cronbach ? opinions on UPPS-P bills ranged away from .71 (Sensation Trying) to help you .86 (Diminished Premeditation) from the higher-BPD category, .76 (Bad Importance) in order to .86 (Sensation Seeking) on the average-BPD category, and you will .75 (Decreased Work) so you can .83 (Not enough Premeditation) in the lower-BPD group.

Research analyses

The assumption of normal distribution of the UPPS-P scale scores and DERS total score was assessed using the Kolmogorov-Smirnov test and Shapiro-Wilks statistic; data were also graphically inspected for outlier detection. The effect of participants’ gender and age on UPPS-P and DERS scale scores was assessed in the context of two-way MANCOVA and ANOVAs, respectively, in which participants’ gender and group membership were entered as fixed factors and participants’ age was entered as a covariate; Pillai V was used as a multivariate effect size measure, whereas ? 2 was used to evaluate the effect size of the univariate F tests. In the case of the MANOVA/MANCOVA analyses, the nominal significance level (i.e., p < .05) of each univariate F test was corrected according to the Bonferroni procedure and set at p < .01. The presence of a significant difference between the high-BPD group and each of the control groups (average- and low-BPD) was tested using Bonferroni simultaneous contrasts; in the case of the UPPS-P scales, Bonferroni contrasts were performed only for those scales that showed significant F values. If no significant effects of participants' gender and age were observed, data were re-analyzed using a one-way MANOVA/ANOVA design, and planned comparisons between the high-BPD group and each of the other groups were carried out on raw mean scores. Cohen's d was used as a measure of effect size for Bonferroni contrasts.

In order to examine the unique relations between BPD group status and both DERS and UPPS-P scores, respectively (above and beyond the other), the DERS total score or relevant UPPS-P scores were included as covariates in ANCOVA designs examining between group differences in the other variable, and the significance of planned Bonferroni contrasts was re-assessed using covariate-adjusted means. In analogy with regression-based P _M statistic, for previously significant Cohen’s d values, we computed a measure of the proportion of mediated effect as the ratio of the difference between the Cohen’s d absolute value for a given contrast that was obtained without considering the effect of the covariate and the d absolute value for the same contrast that was obtained when including the covariate to the d value that was obtained without including the covariate. This measure indicates the proportion of the association between BPD features and both impulsivity and emotion dysregulation, respectively, that can be explained by the other.
