Assessing Self-Definition and Relatedness in Level of Personality Functioning.

The two polarities model (TPM) of personality organizes psychological assessment and psychotherapy and connects to personality disorder diagnosis using the DSM-5 Alternative Model for Personality Disorders (AMPD). The authors developed scales assessing the TPM from an existing self-report measure for level of personality functioning (LPF), a core component of the AMPD. Iterative content analyses of the LPF measure yielded scales for Autonomy and Communion corresponding to dimensions of the TPM. The scales were refined via internal consistency analyses using a measure of psychological attachment and studied in development and validation samples. Associations with relevant external criteria were explored in a series of multiple regressions. The new content-based LPF scales were illustrated with a case vignette. Although the new Autonomy/Communion scales await further validation prior to clinical use, initial evidence suggests that they may bridge the nomological nets of the TPM and AMPD and potentially offer clinical utility in assessment and treatment planning.

Unifying treatment for mild anxiety and depression in preadolescence.

Anxiety disorders in children and adolescents are prevalent and, if left untreated, can lead to comorbid psychological disorders, substance use, poor socioemotional functioning, and academic and occupational underachievement. Subthreshold presentations of anxiety in youth could become problematic if overlooked, resulting in the aforementioned negative outcomes. Thus, it is important to treat such presentations, including with evidence-based treatments such as cognitive-behavioral therapy (CBT). However, because of not meeting the diagnostic criteria for which many CBT protocols were developed, subthreshold presentations of emotional problems could be an especially good match for transdiagnostic treatments like the Unified Protocol for Children (UP-C). Few studies have addressed this application of the UP-C to subthreshold emotion disorders; thus, this study aimed to preliminarily examine in a systemic case analysis (a) the efficacy of the UP-C for a preadolescent patient with mild anxiety/depression, and (b) the clinical utility of assessing both nomothetic and idiographic outcomes. Pre-post and time series outcome data demonstrated significant decreases in symptoms of depression, irritability, and negative reactions to events and significant increases in emotion identification and ownership of emotions. A network analysis of time series data described dynamics between parent and child ratings as well as the importance of child-rated anxiety and parent ratings of child's ownership of emotions. This case study provides evidence for the efficacy of the UP-C with a preadolescent who displayed subclinical symptoms of an emotional disorder. Furthermore, this case study demonstrates the usefulness of nomothetic and idiographic assessments for treating psychological disorders in youth.

Comparative Content Analysis of Self-Report Scales for Level of Personality Functioning.

Content validity analyses of eight self-report instruments for assessing severity of personality disorder (PD), also known as Level of Personality Functioning (LPF), were conducted using the conceptual scheme of the Alternative Model for Personality Disorders (AMPD; APA, 2013). The item contents of these eight inventories were characterized for the LPF constructs of Identity (ID), Self-Direction (SD), Empathy (EM), and Intimacy (IN) along with the pathological personality trait domains of Negative Affectivity, Detachment, Antagonism, Disinhibition, and Psychoticism. Severity of pathology (SV) reflected in item content was also rated. Raters demonstrated robust agreement for AMPD and SV constructs across instruments. Similarity between instrument AMPD construct profiles was quantified by intraclass correlations (ICC). Results showed the instruments were generally similar in AMPD-construct coverage, but some important differences emerged. The subscales of the instruments also were characterized for the degree to which they reflect the four LPF (ID, SD, EM, IN) domain constructs. Collectively, these content validity comparisons clarify the equivalence of instruments for AMPD constructs and the relative proportions of construct coverage within instrument subscales. These results can inform future research with LPF self-report instruments and guide clinicians in selecting an LPF-related instrument for use in practice.
