Yet we do not know whether, or to what extent, item properties among male offenders vary throughout adulthood. With a combined sample of PCL-R data on offenders from Canada and the United States (N = 4,820), we measured item properties for offenders in age groups of Early (18-30 years old), Middle (31-49 years old), and Late (50+ years old) adulthood. Nine items showed differential item functioning across age group comparisons. Among the Early group, the PCL-R Interpersonal and Affective traits were most informative for measuring the latent trait of psychopathy. Among the Late group, the PCL-R Lifestyle and Antisocial items were most informative for the latent trait. These differences in item information illustrate how psychopathy manifests in male offenders throughout adulthood. It is estimated that in 2050 one quarter of the population in Europe will be aged 65 years and older. Although the added value of a palliative care team is emphasized in the literature, the impact of the palliative care team on the symptom burden in older non-cancer patients is not yet well established. To structurally measure symptoms and to investigate whether proactive consultation with a palliative care team results in improvement of symptoms. This study has a prospective comparative design. Older patients, admitted to a Dutch University Medical Centre for who a health care professional had a negative response to the Surprise Question, were selected. In period one, 59 patients completed the Utrecht Symptom Diary (USD) at day one of admission and after 7 days. In period 2 (n = 60), the same procedure was followed; additionally, the palliative care team was consulted for patients with high USD-scores. Significant improvement on the USD Total Distress Score (TSDS)
