The Clinical Utility of the Level of Personality Functioning Scale: A Treatment Perspective.

The Level of Personality Functioning Scale (LPFS) was introduced in DSM-5 to articulate a conceptual foundation for all types of personality psychopathology, and to provide an assessment of the severity of impairment. Constructed using universal human capacities related to self- and interpersonal functioning, the LPFS defines a continuum of 5 levels ranging from optimal functioning to extreme impairments in functioning. While there have been a growing number of empirical studies demonstrating its reliability and validity, the LPFS was designed fundamentally as an informative clinical tool, potentially useful to practitioners working in a variety of roles using diverse interventions.

Associations between borderline personality disorder symptoms and personality functioning in adolescents: A brief report.

Borderline personality disorder (BPD) is a serious mental disorder, which has been linked to a number of negative outcomes in adolescents and adults. BPD is generally linked to more severe impairments in personality functioning. The (differential) association of specific BPD symptoms with severity level, however, has not been explored yet.

Comparing the clinical utility of the alternative model for personality disorders to the Section II personality disorder model: A randomized controlled trial.

The alternative model for personality disorders (AMPD) has been extensively studied over the past decade, but to date there is no direct comparison of the clinical utility of the AMPD model relative to the Section II personality disorder (PD) model in an ecologically valid design. The current study examined the clinical utility of an AMPD-informed assessment procedure and Section II PD assessment procedure as assessed by both patients and clinicians in a randomized controlled trial. A sample of 119 patients were randomly assigned to either an AMPD or a Section II PD assessment procedure.

Head-to-head comparison of the alternative model for personality disorders and Section II personality disorder model in terms of predicting patient outcomes 1 year later.

The present study investigated the predictive validity of Criterion A and B of the Alternative Model for Personality Disorders (AMPD) compared to the DSM-5 Section II personality disorder (PD) model in predicting patient outcomes 1 year after initial assessment, in a hetero-method longitudinal design. A clinical sample of 84 participants were administered both traditional Section II and AMPD interviews by two independent interviewers. One year after assessment, disability (World Health Organization Disability Assessment Schedule 2.

Changes in the classification of personality disorders: Comparing the DSM-5 Section II personality disorder model to the alternative model for personality disorders using structured clinical interviews.

The current study examined the continuity of personality disorder (PD) diagnoses from Section II to Section III (alternative model for personality disorders [AMPD]) when using structured interviews. We investigated the continuity both in terms of stability of prevalence rates and in terms of convergent validity. A clinical sample of 189 participants were concurrently administered both Section II PD and AMPD interviews for diagnosing PD by 2 independent interviewers.

Adverse Effects of Outcome Monitoring Feedback in Patients With Personality Disorders: A Randomized Controlled Trial in Day Treatment and Inpatient Settings.

This study aimed to evaluate the differential effect of outcome monitoring feedback to therapists and to patients on outcomes in cluster B, cluster C, and personality disorder not otherwise specified (PD-NOS) patients. Day treatment patients (n = 112) and inpatients (n = 94) were randomly assigned to a feedback to therapist (FbT), feedback to therapist and patient (FbTP), or no feedback (NFb) condition. Feedback was based on weekly administrations of the Outcome Questionnaire-45 (OQ-45).
