Members regarding the three organizations was indeed given really new Italian brands of your UPPS-P Impulsive Conclusion Measure (UPPS-P; ) and also the DERS self-statement forms. Participants was indeed applied the UPPS-P additionally the DERS two to four months following the very first BPI management. All of the tips have been administered when you look at the arbitrary acquisition. The new BPI, the newest UPPS-P, together with DERS was basically translated into Italian by a couple of authors; for all steps, the new adequacy of your own Italian translations on the particular original products try controlled by English mother-language professional translators by way of back-translations.
Borderline Identification List (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.
Difficulties when you look at the Feeling Control Size (DERS)
The new DERS was thirty-six-items scale that provide a comprehensive research off total emotion dysregulation and half dozen particular dimensions: nonacceptance of bad attitude, issues stepping into mission-led routines whenever disappointed, problems controlling natural routines whenever distressed, limited usage of energetic emotion control procedures, not enough mental feeling, and you can insufficient psychological clearness. The fresh DERS possess displayed a decide to try–retest reliability and you can enough construct and you can predictive authenticity , which is firmly synchronised which have a fresh way of measuring feelings controls one of BPD people (roentgen = -.63; look for ). After that, the fresh DERS has been discovered to have an effective interior feel and sufficient create and convergent authenticity certainly teens old 11–17, in addition to the same foundation structure to that particular included in people . In the present studies, the new DERS complete get demonstrated enough internal surface from the entire test (N = 91), hinge profile search Cronbach ? = .90, and also in the newest higher-BPD classification (Cronbach ? = .89), average-BPD class (Cronbach ? = .78), and you may lowest-BPD classification (Cronbach ? = .79).
