Players throughout the three groups have been applied actually the fresh new Italian sizes of UPPS-P Impulsive Choices Level (UPPS-P; ) therefore the DERS worry about-statement surveys. Players have been applied the latest UPPS-P and the DERS 2 to 4 months pursuing the initially BPI government. Every actions was basically administered inside the random order. The fresh BPI, the newest UPPS-P, together with DERS was indeed translated to the Italian by two of the authors; for everyone tips, the fresh new adequacy of your Italian translations to their respective amazing systems are subject to English mother-tongue top-notch translators thanks to straight back-translations.
Borderline Identification Collection (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 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.
Trouble from inside the Feelings Control Scale (DERS)
New DERS try thirty six-product measure giving a comprehensive investigations away from overall emotion dysregulation along with half a dozen particular size: nonacceptance of bad ideas, problems entering mission-brought practices when disturb, issues managing natural behaviors whenever disturb, minimal use of effective feelings control measures, diminished emotional sense, and you may decreased emotional clarity. The DERS features showed good test–retest reliability and you may enough create and predictive legitimacy , that is firmly coordinated having an experimental measure of feelings control certainly one https://datingranking.net/luxy-review/ of BPD patients (r = -.63; find ). Next, this new DERS has been found to own an excellent inner surface and you may enough build and convergent legitimacy certainly teenagers old eleven–17, in addition to an identical basis construction to that particular included in grownups . In the current data, new DERS complete get showed adequate interior surface regarding whole decide to try (N = 91), Cronbach ? = .90, plus the newest large-BPD classification (Cronbach ? = .89), average-BPD category (Cronbach ? = .78), and reduced-BPD group (Cronbach ? = .79).
