The assessment of serious illness communication (SIC) competence has, to date, primarily utilized tools that are profession-specific and not explicitly designed using competency-based or person-centered frameworks. To address these gaps, we developed and validated a new tool, the Assessment of Clinical Encounters - Communication Tool (ACE-CT). We convened a national panel of interprofessional SIC experts to develop and validate the ACE-CT using a three-phase multi-method approach. Phase 1 focused on item development through review of existing validated tools, and a Bayesian process in which panel members assessed item quality and item-domain correlation. Phase 2 involved item refinement and preliminary validation through stimulated recall interviews using a think-aloud technique. Phase 3 consisted of psychometric analyses for which panel members used the tool to assess video-recorded standardized patient encounters from interprofessional clinicians completing a SIC professional development intervention. In Phase 1, 37 relevant items from previously validated tools were identified, of which 11 items were removed due to redundance. Through the Bayesian process, 14 items were removed and 1 item was generated. Through Phase 2, 2 items were generated, 2 items were combined into 1, and remaining items were refined to optimize measurability and understandability. In Phase 3, reliability was demonstrated through evidence of high internal consistency and moderate reproducibility, both over time and across raters. The tool was found to be responsive and have sound construct validity through evidence of congruence, convergence and credibility. Raters found the tool to be intuitive, easy to complete, and that it accurately captured their perception of the quality of communication observed. The ACE-CT provides a reliable and valid approach to assessing SIC competence among interprofessional clinicians. Through its person-centered orientation, the ACE-CT provides an opportunity to objectively assess elements of SIC that patients and families value. Show less

The 17q21.31 region with various structural forms characterized by the H1/H2 haplotypes and three large copy number variations (CNVs) represents the strongest risk locus in progressive supranuclear palsy (PSP). To investigate the association between CNVs and structural forms on 17q.21.31 with the risk of PSP. Utilizing whole genome sequencing data from 1684 PSP cases and 2392 controls, the three large CNVs (α, β, and γ) and structural forms within 17q21.31 were identified and analyzed for their association with PSP. We found that the copy number of γ was associated with increased PSP risk (odds ratio [OR] = 1.10, P = 0.0018). From H1β1γ1 (OR = 1.21) and H1β2γ1 (OR = 1.24) to H1β1γ4 (OR = 1.57), structural forms of H1 with additional copies of γ displayed a higher risk for PSP. The frequency of the risk sub-haplotype H1c rises from 1% in individuals with two γ copies to 88% in those with eight copies. Additionally, γ duplication up-regulates expression of ARL17B, LRRC37A/LRRC37A2, and NSFP1, while down-regulating KANSL1. Single-nucleus RNA-seq of the dorsolateral prefrontal cortex analysis reveals γ duplication primarily up-regulates LRRC37A/LRRC37A2 in neuronal cells. The copy number of γ is associated with the risk of PSP after adjusting for H1/H2, indicating that the complex structure at 17q21.31 is an important consideration when evaluating the genetic risk of PSP. © 2025 The Author(s).
