Users on the around three teams have been given individually the latest Italian brands of your own UPPS-P Impulsive Choices Measure (UPPS-P; ) together with DERS care about-declaration forms. Members have been administered the latest UPPS-P and DERS two to four months following 1st BPI management. All measures have been applied from inside the arbitrary buy. The new BPI, the UPPS-P, in addition to DERS were interpreted towards the Italian by the two of the authors; for all strategies, the fresh new adequacy of one’s Italian translations on the particular brand new systems is actually controlled by English mommy-tongue professional translators as a consequence of back-translations.
Borderline Character Catalog (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 http://datingranking.net/luxy-review/,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.
Problems in the Feelings Regulation Size (DERS)
The new DERS is 36-goods level that provides an intensive assessment of full emotion dysregulation together with half dozen particular size: nonacceptance away from negative attitude, troubles getting into mission-led habits when distressed, troubles managing spontaneous habits when troubled, limited entry to active feeling regulation tips, decreased mental sense, and you will decreased mental clarity. The fresh DERS have presented a great shot–retest reliability and you can enough construct and you may predictive authenticity , in fact it is highly synchronised having an experimental way of measuring feeling regulation certainly one of BPD clients (roentgen = -.63; find ). Then, brand new DERS has been seen having a good interior consistency and you may enough build and you can convergent validity one of kids old eleven–17, in addition to an equivalent grounds structure to this found in people . In the present research, brand new DERS full score presented adequate inner consistency regarding whole try (N = 91), Cronbach ? = .90, and in the brand new higher-BPD group (Cronbach ? = .89), average-BPD group (Cronbach ? = .78), and you can lowest-BPD classification (Cronbach ? = .79).
