SummaryThe Clifton Assessment Schedule and the Shortened Stockton Rating Scale were administered to 38 elderly, mentally handicapped patients. Inter-rater reliability was high and the CAS was found to be a useful measure of cognitive ability. The tests measure different features of patients, but both correlated significantly with estimated levels of independence.

ABSTRACTBackground:Patients with dementia may be unable to describe their symptoms, and caregivers frequently suffer emotional burden that can interfere with judgment of the patient's behavior. The Neuropsychiatric Inventory-Clinician rating scale (NPI-C) was therefore developed as a comprehensive and versatile instrument to assess and accurately measure neuropsychiatric symptoms (NPS) in dementia, thereby using information from caregiver and patient interviews, and any other relevant available data. The present study is a follow-up to the original, cross-national NPI-C validation, evaluating the reliability and concurrent validity of the NPI-C in quantifying psychopathological symptoms in dementia in a large Brazilian cohort.Methods:Two blinded raters evaluated 312 participants (156 patient-knowledgeable informant dyads) using the NPI-C for a total of 624 observations in five Brazilian centers. Inter-rater reliability was determined through intraclass correlation coefficients for the NPI-C domains and the traditional NPI. Convergent validity included correlations of specific domains of the NPI-C with the Brief Psychiatric Rating Scale (BPRS), the Cohen-Mansfield Agitation Index (CMAI), the Cornell Scale for Depression in Dementia (CSDD), and the Apathy Inventory (AI).Results:Inter-rater reliability was strong for all NPI-C domains. There were high correlations between NPI-C/delusions and BPRS, NPI-C/apathy-indifference with the AI, NPI-C/depression-dysphoria with the CSDD, NPI-C/agitation with the CMAI, and NPI-C/aggression with the CMAI. There was moderate correlation between the NPI-C/aberrant vocalizations and CMAI and the NPI-C/hallucinations with the BPRS.Conclusion:The NPI-C is a comprehensive tool that provides accurate measurement of NPS in dementia with high concurrent validity and inter-rater reliability in the Brazilian setting. In addition to universal assessment, the NPI-C can be completed by individual domains.

This study aimed to evaluate the psychometric properties of the Elderly Mobility Scale (EMS) in an acute hospital setting. Intra-rater (n=15) and inter-rater (n=18) reliability were investigated using physiotherapists who viewed and scored video-recorded mobility assessments using the EMS on two occasions, one week apart. Latent class analysis of EMS scores showed that neither the occasion of testing (intra-rater reliability) (R2=0.0035, p=0.72), therapist (inter-rater reliability (R2=0.0051, p=1.00), years of experience (R2=0.0058, p=1.00) nor number of EMS assessments previously completed (R2=0.0048, p=1.00) had any impact on the EMS scores. The only factor which impacted on clustering was the EMS score (R2=0.8263, p=0.000). Concurrent validity was assessed by comparison with the Modified Rivermead Mobility Index (MRMI) in patients aged ≥ 55 years (n = 32) and demonstrated that EMS scores were highly correlated with the MRMI (Spearman’s ρ=0.887). Therefore intra-rater reliability of the EMS has been reported for the first time, and inter-rater reliability and concurrent validity of the EMS have been further supported and extended into a younger patient group for mobility assessment in acute hospital patients.

Idiopathic Dystonia

Background: The Dyskinesia Impairment Scale (DIS) is a new assessment scale for dystonia and choreoathetosis in children and youth with dyskinetic cerebral palsy. Today, the Burke–Fahn–Marsden Dystonia Rating Scale (BFM) is mostly used to assess dystonia in children with inherited dystonia. The aim of this study was to assess reliability and validity of the DIS in children and youth with inherited or idiopathic dystonia. Methods: Reliability was measured by (1) the intraclass correlation coefficients (ICCs) for inter-rater and test-retest reliability, as well as (2) standard error of measurement (SEM) and minimal detectable difference (MDD). For concurrent validity of the DIS-dystonia subscale, the BFM was administered. Results: In total, 11 males and 9 females (median age 16 years and 7 months, range 6 to 24 years) were included. For inter-rater reliability, the ICCs for the DIS total score and the dystonia and choreoathetosis subscale scores were 0.83, 0.87, and 0.71, respectively. For test-retest reliability, the ICCs for the DIS total score and the dystonia and choreoathetosis subscale scores were 0.95, 0.88, and 0.93, respectively. The SEM and MDD for the total DIS were 3.98% and 11.04%, respectively. The Spearman correlation coefficient between the dystonia subscale and the BFM was 0.88 (p < 0.01). Conclusions: Good to excellent inter-rater, test-retest reliability, and validity were found for the total DIS and the dystonia subscale. The choreoathetosis subscale showed moderate inter-rater reliability and excellent test-retest reliability. The DIS may be a promising tool to assess dystonia and choreoathetosis in children and young adults with inherited or idiopathic dystonia.

IntroductionDelirium is characterized by the rapid onset of symptoms which fluctuate, with an altered level of consciousness, global disturbance of cognition, perceptual abnormalities and evidence of a physical cause (DSM-IV-R, 2002).AimTo review the characteristics and psychometric properties of thirteen Delirium scales available in research and clinical practice.MethodsMEDLINE database was used to identify the delirium scales in use (1990–2010), using the keywords: delirium, confusion, questionnaires, scales, severity and screening. Only validation studies were included. Exclusion criteria were children and alcohol/drug delirium assessment scales. This study included seven screening scales: Confusion Assessment Method, Intensive Care Delirium Screening Checklist, Delirium Symptom Interview, NEECHAM Confusion Scale, Cognitive Test for Delirium, Delirium Observation Screening, Nursing Delirium Screening Scale and seven severity scales: Delirium Rating Scale, Memorial Delirium Assessment Scale, Confusional State Evaluation, Delirium Severity Scale, Delirium Index and Delirium-O-Meter.ResultsThe majority of scales were based on the Diagnosis Statistical Manual Criteria as well as on a review of selected symptoms of Delirium informed by systematic clinical observation and formal brief assessment of mental status. In most of the studies, for psychometric analysis, the inter-rater reliability and validity with severity of Delirium assessment and cognitive screening tests were used.ConclusionBearing in mind the recent review studies included, we can conclude that CAM is the most widely used instrument for delirium assessment.

SYNOPSISThe Psychogeriatric Assessment Scales (PAS) provide an assessment of the clinical changes seen in dementia and depression. Principal components analysis and latent trait analysis were used to develop a set of scales to summarize these clinical changes. There are three scales derived from an interview with the subject (Cognitive Impairment, Depression, Stroke) and three from an interview with an informant (Cognitive Decline, Behaviour Change, Stroke). Results are reported on the reliability and validity of these scales using data from clinical samples in Sydney and Geneva and a population sample from Canberra. The scales were found to have excellent validity when judged against clinical diagnoses of dementia and depression and could distinguish Alzheimer's from vascular dementia. Cut-off points were developed to indicate correspondence between scale scores and clinical diagnoses. Percentile rank norms were developed from the Canberra population sample. The PAS is easy to administer and score and can be used by lay interviewers after training. It is intended for application both in research and in services for the elderly.

ABSTRACTBackground: The field of geriatric medicine has identified a need for an evaluative tool that can rapidly quantify global cognitive ability and accurately monitor change over time in patients with a wide range of impairments. We hypothesized that the development of an adaptive test approach to cognitive measurement would help to meet that need. This study aimed to provide evidence for the interpretability of scores obtained from a novel, adaptive approach to cognitive assessment, called the Geriatric Rapid Adaptive Cognitive Estimate (GRACE) method.Methods: An adaptive method for cognitive assessment was developed using data from 185 patients referred for geriatric cognitive assessment, and pilot tested in an additional 137 patients. Correlations between test scores and between rank orders of patients were computed to examine the reliability and validity of cognitive ability scores obtained by (1) administering test questions out of their usual order, (2) administering only a subset of questions, and (3) administering questions adaptively using simplified selection rules based on the most difficult question passed.Results: Cognitive ability scores obtained with the GRACE method correlated highly with the Montreal Cognitive Assessment (MoCA) scores (r = 0.93) and ranked patients similarly in order of ability (r > 0.87). A simplified adaptive testing algorithm for pencil-and-paper assessment demonstrated moderately high correlations with scores obtained from administering the full set of MMSE and MoCA items as well as the MoCA items alone.Conclusions: Scores from the GRACE method can be obtained easily in 5–10 minutes, reducing test burden. The resulting numeric score quantifies cognitive ability, allowing clinicians to compare patients and monitor change in global cognition over time. The adaptive nature of this method allows for evaluation of persons across a broader range of cognitive ability levels than currently available tests.

ABSTRACTBackground: Neuropsychiatric symptoms (NPS) affect almost all patients with dementia and are a major focus of study and treatment. Accurate assessment of NPS through valid, sensitive and reliable measures is crucial. Although current NPS measures have many strengths, they also have some limitations (e.g. acquisition of data is limited to informants or caregivers as respondents, limited depth of items specific to moderate dementia). Therefore, we developed a revised version of the NPI, known as the NPI-C. The NPI-C includes expanded domains and items, and a clinician-rating methodology. This study evaluated the reliability and convergent validity of the NPI-C at ten international sites (seven languages).Methods: Face validity for 78 new items was obtained through a Delphi panel. A total of 128 dyads (caregivers/patients) from three severity categories of dementia (mild = 58, moderate = 49, severe = 21) were interviewed separately by two trained raters using two rating methods: the original NPI interview and a clinician-rated method. Rater 1 also administered four additional, established measures: the Apathy Evaluation Scale, the Brief Psychiatric Rating Scale, the Cohen-Mansfield Agitation Index, and the Cornell Scale for Depression in Dementia. Intraclass correlations were used to determine inter-rater reliability. Pearson correlations between the four relevant NPI-C domains and their corresponding outside measures were used for convergent validity.Results: Inter-rater reliability was strong for most items. Convergent validity was moderate (apathy and agitation) to strong (hallucinations and delusions; agitation and aberrant vocalization; and depression) for clinician ratings in NPI-C domains.Conclusion: Overall, the NPI-C shows promise as a versatile tool which can accurately measure NPS and which uses a uniform scale system to facilitate data comparisons across studies.
