Professionals on the about three teams have been given directly the fresh new Italian types of your own UPPS-P Impulsive Decisions Measure (UPPS-P; ) while the DERS care about-statement forms. People had been applied the fresh UPPS-P and DERS 2 to 4 months adopting the 1st BPI management. All measures was basically administered in the random purchase. This new BPI, this new UPPS-P, therefore the DERS was indeed interpreted on the Italian by two of the authors; for everybody tips, the fresh new adequacy of Italian translations to their respective brand spanking new models are subject to English mother-language professional translators compliment of right back-translations.

Borderline Identification Index (BPI)

The BPI is a 53–item self–report questionnaire based on Kernberg’s concept of borderline personality organization . It assesses a broad range of phenomenological manifestations of BPD pathology, including affectivity and identity disturbances, fear of closeness, interpersonal instability, self–harming/suicidal behavior, impulsive behavior, dissociative symptoms and psychotic symptoms. Applying a modification of the original true–false (yes/no) rating of the items , items were scored on a Likert-type scale with four levels of agreement ranging from “disagree strongly” to “agree strongly” . The BPI yields a total score that is a dimensional measure of overall BPD psychopathology (with higher scores corresponding to greater BPD psychopathology). Only the first 51 items of the BPI are summed to compute the BPI total score (which can range from 51 to 204). In adult participants, the BPI has been found to be a reliable and valid measure of BPD, with sensitivity and specificity data showing that the BPI identifies independently diagnosed patients with sufficient hit rates . Likewise, in adult participants, the BPI total score has been shown to yield good agreement with Gunderson’s DIB-R [46, 47] and DSM-III-R diagnostic criteria for BPD . Of particular relevance to this study, the BPI has also been found to be a reliable measure of BPD features in samples of adolescents . In support of the measure’s construct validity, scores on the Italian version of the BPI (Cronbach ? = .93) have been found to evidence significant associations with self-reports of childhood sexual https://datingranking.net/sexfinder-review/ abuse, r = .29, p < .001, childhood neglect, r = .33, p < .001, and emotion dysregulation (as assessed with the DERS), r = .39, p < .001, in a sample of Italian nonclinical adults (N = 431, 58.2% female, mean age = 35 ± 16).

In the present study, the Cronbach ? values of the BPI total scores were .91 and .97 in the screening sample (N = 1,157) and the three groups combined, respectively. Similar Cronbach ? values were observed for the BPI total score within each group. In the present study, a subsample of 75 adolescents (41.3% female, mean age = years, SD = 1.74) agreed to be re-administered the Italian version of the BPI one month after the first administration; the value of the test-retest reliability coefficient was good, r = .85, p < .001.

Issues inside the Emotion Regulation Level (DERS)

This new DERS was 36-item level that give an intensive review away from complete emotion dysregulation also half dozen specific size: nonacceptance out-of negative thoughts, dilemmas stepping into purpose-brought behavior when upset, dilemmas managing spontaneous habits whenever upset, restricted accessibility effective feelings regulation steps, not enough emotional feel, and you will diminished emotional quality. The DERS has presented a great test–retest reliability and you may sufficient construct and you may predictive validity , that is strongly synchronised which have an experimental way of measuring feeling controls certainly one of BPD customers (r = -.63; select ). Next, the brand new DERS has been seen getting a good internal feel and you will enough construct and you can convergent authenticity one of teens old 11–17, along with an identical basis framework to that particular included in people . In the current study, the brand new DERS total rating displayed sufficient interior structure regarding the whole shot (N = 91), Cronbach ? = .ninety, plus in this new large-BPD classification (Cronbach ? = .89), average-BPD category (Cronbach ? = .78), and low-BPD category (Cronbach ? = .79).
