      functioning analysis of ICD-11 inventories.

AB  - OBJECTIVES: The contested categorical personality disorder (PD) criteria are not 
      well suited to inform PD diagnoses in older adults. Yet, the classification of 
      PDs is undergoing a critical transition phase with a paradigm shift to a 
      dimensional approach for diagnosing PDs. No special attention was given to the 
      expression of PDs in older age when the dimensional ICD-11 model was developed. 
      Given that PDs are highly prevalent in older adults, there is an urgent need to 
      examine if ICD-11 related instruments are able to adequately assess for PDs in 
      older adults. METHODS: The age-neutrality of ICD-11 measures was examined in a 
      sample of 208 Dutch community-dwelling adults (N = 208, M age = 54.96, 
      SD = 21.65), matched on sex into 104 younger (age range 18-64) and 104 older (age 
      range 65-93) adults. An instrument is considered not to be age-neutral if a 
      collective large level of differential item functioning (DIF) exists in a group 
      of items of an instrument (i.e., 25% or more with DIF). We therefore set out to 
      detect possible DIF in the following ICD-11 self-report measures: the 
      Standardized Assessment of Severity of Personality Disorder (SASPD), the 
      Personality Inventory for ICD-11 (PiCD), and the Borderline Pattern Scale (BPS). 
      RESULTS: DIF analyses using a non-parametric odds ratio approach demonstrated 
      that SASPD, PiCD, and BPS were age-neutral with less than 25% of items showing 
      DIF. Yet, impact of DIF at scale level, examined by way of differential test 
      functioning (DTF), indicated a DTF effect on the SASPD total score. CONCLUSIONS: 
      These results of age-neutrality of the PiCD and BPS are promising for measuring 
      ICD-11 traits and the borderline pattern. Yet, the age-neutral measurement of PD 
      severity requires further research. With a rapidly aging population, its accurate 
      assessment across the entire adult life span, including older age, is a 
      prerequisite for an adequate detection of PDs.
