Clinical profiles of adolescent personality pathology: a latent structure examination of the Semi-Structured Interview for Personality Functioning DSM-5 (STiP-5.1) in a help-seeking sample.

Background: Despite the introduction of dimensional conceptualisations of personality functioning in the latest classification systems, such as Criterion A of the Alternative Model of Personality Disorders in the DSM-5, heterogeneous clinical presentation of personality pathology remains a challenge. Relatedly, the latent structure of personality pathology as assessed by the Semi-Structured Interview for Personality Functioning DSM-5 (STiP-5.1) has not yet been comprehensively examined in adolescents.

Age dependent effects of early intervention in borderline personality disorder in adolescents.

Background: Psychological treatments for young people with sub-threshold or full-syndrome borderline personality disorder (BPD) are found to be effective. However, little is known about the age at which adolescents benefit from early intervention. This study investigated whether age affects the effectiveness of early intervention for BPD.

Is a brief screen for personality disorder clinically useful for the detection of impairment in personality functioning in adolescents?

The Standardized Assessment of Personality-Abbreviated Scale (SAPAS) has been used extensively to screen for personality disorders (PD), including adolescents. Yet, it is unclear how well the SAPAS performs in screening for impairment in personality functioning (IPF), Criterion A of the alternative model for PD (AMPD) in adolescent samples. We examined the performance of the SAPAS in detecting IPF at a diagnostic threshold for PD in the AMPD.
