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.

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.

ABSTRACT The issue of this article concerned the discussion about tools frequently used tools for assessing neuropsychiatric symptoms of patients with dementia, particularly Alzheimer's disease. The aims were to discuss the main tools for evaluating behavioral disturbances, and particularly the accuracy of the Neuropsychiatric Inventory - Clinician Rating Scale (NPI-C). The clinical approach to and diagnosis of neuropsychiatric syndromes in dementia require suitable accuracy. Advances in the recognition and early accurate diagnosis of psychopathological symptoms help guide appropriate pharmacological and non-pharmacological interventions. In addition, recommended standardized and validated measurements contribute to both scientific research and clinical practice. Emotional distress, caregiver burden, and cognitive impairment often experienced by elderly caregivers, may affect the quality of caregiver reports. The clinician rating approach helps attenuate these misinterpretations. In this scenario, the NPI-C is a promising and versatile tool for assessing neuropsychiatric syndromes in dementia, offering good accuracy and high reliability, mainly based on the diagnostic impression of the clinician. This tool can provide both strategies: a comprehensive assessment of neuropsychiatric symptoms in dementia or the investigation of specific psychopathological syndromes such as agitation, depression, anxiety, apathy, sleep disorders, and aberrant motor disorders, among others.

Background: In health-care settings, the use of the Neuropsychiatric Inventory-Nursing Home (NPI-NH) may not always be consistent with the authors’ guidelines, which affects its reliability. To avoid this bias, a diary version of the NPI (NPI-Diary) was developed. Aims: This study aimed to evaluate the psychometric properties (internal consistency and reliability) of the NPI-Diary, and examined its convergence with the NPI-NH. Methods: Two raters administered the NPI-NH and NPI-Diary to 40 participants with Alzheimer’s disease, selected randomly from a hospital’s weekly turnover. Results: The NPI-Diary exhibited adequate internal consistency (total: α = 0.581) and test-retest reliability (total: ρ = 0.711; p < 0.01). The interrater reliability values (ICC) for the NPI-NH and NPI-Diary differed significantly (Total: NPI-NH ICC = 0.506, NPI-Diary ICC = 0.879; Frequency: NPI-NH ICC = 0.51, NPI-Diary ICC = 0.798; Severity: NPI-NH ICC = 0.491, NPI-Diary ICC = 0.809). The convergent validity between the two inventories was also significant (total: ρ = 0.48; p < 0.01). Conclusions: The NPI-Diary showed more appropriate validity and reliability compared to the NPI-NH, when administered in a highly variable sample, as is generally the case in the current health-care setting.

Purpose – The UKU side effect rating scale for adults with intellectual disabilities (UKU-SERS-ID) was developed to detect side effects among patients with intellectual disabilities (ID). The purpose of this paper is to examine the reliability and face validity of the UKU-SERS-ID. Design/methodology/approach – UKU-SERS-ID comprises 35 items. In total, 22 patients with ID were included from two specialized services for adults with ID and comorbid mental illness. All patients were rated on three different occasions by three clinicians; two nurses and one medical doctor. Reliability was estimated with Cohen’s κ. A focus group discussed the face validity of the items comprising the UKU-SERS-ID. Findings – Respectively ten (nurse-nurse scores) and eight (nurse-doctor scores) items were considered difficult to score due to low prevalence of the symptoms. For the other items the reliability was acceptable. Through discussion in a focus group, with the reliability scores in mind, only one of the items of the UKU-SERS-ID was discarded. Practical implications – The authors have developed a feasible side effect instrument for clinical practice. It is easy to score and relevant regarding important side effects. Originality/value – The UKU-SERS-ID seems to be a feasible tool. Further investigations are mandatory in order to gain knowledge about distribution and phenomenology of side effects from psychotropic medication for individuals with ID.

Purpose The purpose of this paper is to assess whether the Adult Attachment Projective (AAP) Picture System is a reliable and face valid measure of internal working models of attachment in adults with intellectual disabilities (ID). Design/methodology/approach The AAPs of 20 adults with ID were coded blind by two reliable judges and classified into one of four groups: secure, dismissing, preoccupied, or unresolved. Inter-rater reliability was calculated using κ. Six participants repeated the assessment for test-retest reliability. Two independent experts rated ten cases on the links between the AAP analysis and the clinical history. Findings There was significant agreement between AAP judges, κ=0.677, p<0.001. Five out of six participants showed stability in their classifications over time. The majority of expert ratings were “good” or “excellent”. There was a significant inter-class correlation between raters suggesting good agreement between them r=0.51 (p<0.05). The raters’ feedback suggested that the AAP had good clinical utility. Research limitations/implications The inter-rater reliability, stability, face validity, and clinical utility of the AAP in this population is promising. Further examination of these findings with a larger sample of individuals with ID is needed. Originality/value This is the first study attempting to investigate the reliability and validity of the AAP in this population.

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.

The current study was conducted with the aim of examining the confirmatory factor structure of the revised Persian version of self-compassion rating scale among a group of male prisoners of Sepidar prison of Ahvaz. One hundred and seventy-eight male prisoners were selected using convenient sampling method among male prisoners and completed RPVSC and GHQ-11-item. The confirmatory factor analysis confirmed 6 factors. The Cronbach’s α coefficient for the entire scale was .91, for the 6 factors was from .77 to .92 and its convergent validity with the General Health Questionnaire was -.45 and for the 6 subscales with the GHQ was calculated from -.28 to -.48. Finally, the self-compassion scale can be used as a validated instrument in assessing aspects of self-compassion in male prisoners population.
