  • Positive Constructs in Schema Therapy

    Open AccessLoes Van Donzel, Anne‐Marie Claassen et al.ARTICLEJournal of Clinical Psychology2026

    Central to the schema therapy model is the development of early maladaptive schemas due to unmet emotional needs in childhood.

  • Sensitivity, Specificity and Interrater Reliability of a Clinical Staging Model for Personality Disorders in Older Adults

    Roel J Schepman, Roel Schepman et al.ARTICLEJournal of Personality Assessment2026

    A recent Delphi study found expert-consensus that clinical staging (CS) could provide a valid framework in the assessment of personality disorders (PDs) in older adults (Conjaerts et al., 2025). The categorical models used currently to assess PDs are poorly suited for treatment selection, in older adults even more so as age-specific factors were not considered in the development. The aim of this study was to investigate the interrater reliability…

  • Validity of the LPFS-BF 2.0 and PID-5-BF+M in Older Adults

    M Facon, Y Le Corff et al.ARTICLEJournal of Personality Assessment2026

    This study evaluates the validity of the LPFS-BF 2.0 and PID-5-BF+M in older adults, focusing on (a) factor structure, (b) measurement invariance across languages and countries, and (c) nomological network. These tools assess personality functioning and maladaptive traits based on the hybrid/dimensional approaches of personality pathology. Two samples of adults aged 65 and older were recruited: a French-speaking Canadian sample (N = 452) and a Du…

    Machteld A Ouwens, Loes Van Donzel et al.ARTICLEJournal of Personality Assessment2025

    In schema therapy early adaptive schemas (EASs) and early maladaptive schemas (EMSs) have been found to be independent but related constructs. The Young Positive Schema Questionnaire (YPSQ) was developed and validated in English to measure EASs. The present study investigated psychometric properties of the Dutch translation in a representative sample of 650 non-clinical Dutch individuals. Internal consistencies for all scales were assessed to be …
