Rathus, Wagner, and Miller recently reported on the development and psychometric evaluation of the Life problems Inventory (LPI), a self report tool to measure Linehan's conceptualition of borderline personality disorder (BPD) as a disorder primarily of the emotion regulation system, and in particular, problems with regulation of emotions, impulses, relationships, and self. Thus, the LPI maps onto the content of her skills training component of Dialectical Behavior Therapy (DBT), with scales assessing problems addressed in DBT skills modules targeting emotion regulation, distress tolerance, interpersonal effectiveness, and mindfulness. The present study furthers the investigation of the LPI's psychometrics by examining internal consistency, test-retest reliability, convergent validity with depression, suicidality and mindfulness, and discriminant validity with social desirability in an adolescent/young adult, non-clinical, suburban college student sample (N = 99). The LPI was found to be internally consistent, stable over a two-week retest interval, and related in expected ways with clinical constructs. We discuss implications for further development and application of the LPI and its utility in a college population.Keywords: Borderline personality; Measurement; College students;
Life problemsLinehan [1][2][3] developed Dialectical Behavior Therapy as a comprehensive treatment to address the problems of women with BPD and chronic suicide-related behavior. Its success in reducing suicidal and non-suicidal self-injurious behavior (NSSI), reducing hospitalizations, and retaining patients in therapy has made it a standard treatment modality for this population, and numerous randomized clinical trials support its effectiveness [4][5][6]. In addition to these stability and safety-related variables, DBT has also resulted in increases in quality of life measures such as depression, hopelessness, suicidal ideation, social adjustment, and anger [7]. Further, DBT appears promising for adolescents [8][9][10][11][12][13] and for patients with BPD and other co-morbid problems such as substance abuse [14] and eating disorders [15].Currently used widely in outpatient and inpatient settings [10,16], DBT integrates traditional cognitive-behavioral approaches with Eastern acceptance and meditation practices [17]. DBT views individuals with BPD as experiencing core problems of emotional dysregulation that contribute to dysfunction across domains of interpersonal functioning, behavioral regulation/impulsivity, and self/cognitive regulation [1]. Therefore, in addition to individual therapy, a central modality of DBT is skills training in Emotion Regulation, Interpersonal Effectiveness, Distress Tolerance, and Mindfulness, to address capability deficits associated with these areas [2,3].Despite the many replications and extensions of DBT efficacy studies for patients with problems of regulation of emotions and behaviors, none of the many standardized measures of BPD directly and comprehensively assesses the four core problem a...
