Abstract
It is commonly accepted that gathering information via multiple assessment methods (e.g., interview and questionnaire, self- and informant report) is important for establishing construct validity. Although numerous articles report convergent and discriminant agreement correlations between self- and other ratings of personality, studies of the structure of personality from such ratings are less common. The present study addresses this gap using a meta-analytic data set (N range = 157-9,295) of various versions (i.e., self- and other-report, full-length and short alternative format) of the Schedule for Nonadaptive and Adaptive Personality (SNAP; Clark, 1993; Clark, Simms, Wu, & Casillas, 2014). We hypothesized that (a) structures across all measure formats would be highly comparable and (b) to the extent that they were dissimilar, perspective (self vs. other) and measure format (long vs. short form), respectively, would influence comparability. Results revealed strong congruence among 3-factor structures (Negative Emotionality, Positive Emotionality, and Disinhibition vs. Constraint) across all versions of the SNAP, suggesting that personality as assessed by this broad measure of personality traits across the normal-abnormal spectrum has a robust structure across different rater perspectives and rating formats. Because the comparability analyses were highly congruent and differences among the comparisons were minimal, we concluded-contrary to our expectations-that different formats and different rater perspectives have little effect on structural comparability. Results generally support Funder's (1995) realistic accuracy model, suggesting that trait relevance, cue detection, and information usage are key factors in structuring informant ratings. Limitations of the present study and implications for future research are discussed. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Abstract
Assessment of an individual's functional status, as measured by activities of daily living (ADL), is an essential element in the diagnosis of HIV-associated neurocognitive disorders (HAND) but individuals with cognitive impairment may not accurately report ADL. We assessed agreement between self- and caregiver-reported ADL in HIV-positive persons. Antiretroviral therapy (ART)-naïve HIV-positive persons (n = 321) and HIV-negative controls (n = 134) in Rakai, Uganda, completed neurocognitive tests and an ADL questionnaire. Co-resident relatives ("caregivers") were independently administered the ADL questionnaire to determine their perception of the participant's ADL. The relationship between neurocognitive impairment and participant-caregiver agreement was assessed using kappa statistics. Regression was used to estimate adjusted prevalence ratios (AdjPR) of participant-caregiver agreement on disability scores. Relative to HIV-negative adults, HIV-positive participants scoring at least 1 standard deviation (SD) below the norm on 2 or more neurocognitive tests were classified as having mild neurocognitive impairment and those scoring at least 2 SD below the norm on 2 or more neurocognitive tests were classified as having moderate-to-severe. Mean age was 36 years (SD 8.9), and 53% of participants were male. The rate of ADL agreement between participants and caregivers was 77% for HIV-positive and 87% for HIV-negative participants (AdjPR = 0.89, 95% CI 0.81-0.97, p = .01). Among HIV-positive participants, 41% had moderate neurocognitive impairment, 15% had severe neurocognitive impairment, and 44% were normal. For moderate neurocognitive impairment, the rate of ADL agreement was 69% and for severe neurocognitive impairment, it was 66%. Compared to non-impaired HIV-positive participants (86% ADL agreement), ADL agreement was lower with moderate impairment (AdjPR = 0.89, 95%CI 0.81-0.98, p = .023) and severe impairment (AdjPR = 0.77, 95%CI 0.63-0.95, p = .014). Gender, education and CD4 count were not associated with ADL agreement. HIV-positive persons with neurocognitive impairment have lower agreement with caregivers' reports of ADL than HIV-positive persons without cognitive impairment.

Abstract
Aims To develop clinical descriptions (vignettes) of life with Alzheimer’s disease (AD), we conducted focus groups of persons with AD (n = 14), family caregivers of persons with AD (n = 20), and clinicians who see persons with AD in their practices (n = 5). Methods Group participants read existing descriptions of AD and commented on the realism and comprehensibility of the descriptions. We used thematic framework analysis to code the comments into themes and develop three new vignettes to describe mild, moderate, and severe AD. Results Themes included the types of symptoms to mention in the new vignettes, plus the manner in which the vignettes should be written. Since the vignette descriptions were based on focus group participants’ first-hand knowledge of AD, the descriptions can be said to demonstrate content validity. Conclusion Members of the general public can read the vignettes and estimate their health-related quality-of-life (HRQoL) as if they had AD based on the vignette descriptions. This is especially important for economic evaluations of new AD medications, which require HRQoL to be assessed in a manner that persons with AD often find difficult to undertake. The vignettes will allow the general public to serve as a proxy and provide HRQoL estimates in place of persons with AD.

Abstract
OBJECTIVE For people with dementia, the concept of quality of life (Qol) reflects the disease's impact on the whole person. Thus, Qol is an increasingly used outcome measure in dementia research. This systematic review was performed to identify available dementia-specific Qol measurements and to assess the quality of linguistic validations and reliability studies of these measurements (PROSPERO 2013: CRD42014008725). STUDY DESIGN AND SETTING The MEDLINE, CINAHL, EMBASE, PsycINFO, and Cochrane Methodology Register databases were systematically searched without any date restrictions. Forward and backward citation tracking were performed on the basis of selected articles. RESULTS A total of 70 articles addressing 19 dementia-specific Qol measurements were identified; nine measurements were adapted to nonorigin countries. The quality of the linguistic validations varied from insufficient to good. Internal consistency was the most frequently tested reliability property. Most of the reliability studies lacked internal validity. CONCLUSION Qol measurements for dementia are insufficiently linguistic validated and not well tested for reliability. None of the identified measurements can be recommended without further research. The application of international guidelines and quality criteria is strongly recommended for the performance of linguistic validations and reliability studies of dementia-specific Qol measurements.

Abstract
OBJECTIVES Ascertaining the quality of life (QoL) in people with dementia is important for evaluating service outcomes and cost-effectiveness. This paper identifies QoL measures for people with dementia and assesses their properties. METHOD A systematic narrative review identified articles using dementia QoL measures. Electronic databases searched were AMED, CINAHL, EMBASE, Index to Theses, IBSS, MEDLINE, PsycINFO, Sociological Abstracts, and Web of Science. All available years and languages (if with an English language abstract) were included. RESULTS Searches yielded 6806 citations; 3043 were multiple duplicates (759 being true duplicates). Abstracts were read; 182 full papers were selected/obtained, of which 126 were included as relevant. Few measures were based on rigorous conceptual frameworks. Some referenced Lawton's model (Dementia Quality of Life [DQOL] and Quality of Life in Alzheimer's Disease [QOL-AD]), though these tapped part of this only; others claimed relationship to a health-related QoL concept (e.g. DEMQOL), though had less social relevance; others were based on limited domains (e.g. activity, affect) or clinical opinions (Quality of Life in Late-Stage Dementia [QUALID]). Many measures were based on proxy assessments or observations of people with dementia's QoL, rather than their own ratings. The Bath Assessment of Subjective Quality of Life in Dementia (BASQID) was developed involving people with dementia and caregivers, but excluded some of their main themes. All measures were tested on selective samples only (ranging from community to hospital clinics, or subsamples/waves of existing population surveys), in a few sites. Their general applicability remains unknown, and predictive validity remains largely untested. CONCLUSION The lack of consensus on measuring QoL in dementia suggests a need for a broader, more rigorously tested QoL measure.

Abstract
Objectives To validate the ICECAP-O capability wellbeing measure’s German translation in older people with dementia living in a nursing home, and to investigate the influence of proxy characteristics on responses. Method Cross-sectional study. For 95 residents living in a German nursing home, questionnaires were completed by nursing professionals serving as proxy respondents. We investigated the convergent validity of the ICECAP-O with other Quality of Life (Qol) measures, the EQ-5D extended with a cognitive dimension (EQ-5D+C), the Alzheimer’s Disease Related Quality of Life (ADRQL) measures, and the Barthel-index measure of Activities of Daily Living (ADL). Discriminant validity was investigated using bivariate and multivariate stepwise regression analysis, comparing ICECAP-O scores between subgroups varying in dementia severity, care dependency, ADL status and demographic characteristics. Results Convergent validity between the ICECAP-O, EQ-5D+C, ADRQL and Barthel-Index scores was moderate to good (with correlations of 0.72, 0.69 and 0.53 respectively), but differed considerably between dimensions of the instruments. Discriminant validity was confirmed by finding differences in ICECAP-O scores between subgroups based on ADL scores (0.58 below 65 points on the Barthel-index and 0.80 above 65 points) and other characteristics. The ICECAP-O scores based on available tariffs were related to proxy characteristics gender (0.52 males versus 0.65 females) and work experience (0.61 below 2 years of experience versus 0.68 above 2 years). Discussion The results of this study suggest that the ICECAP-O is a promising generic measure for general Qol and capability of people with dementia living in a nursing home. Validity tests generally yielded favorable results. Work experience and gender appeared to influence proxy response, which raises questions regarding appropriate proxies, especially since the ICECAP-O may be completed by proxies relatively often. Further research is necessary to validate the German version of the ICECAP-O, with specific attention to proxy completion for people with dementia.

Abstract
The objective of this study was to validate a Spanish version of the Cornell-Brown Scale (CBS) for quality of life (QoL) in dementia. One hundred persons with mild-to-moderate dementia (Diagnostic and Statistical Manual of the American Psychiatric Association, 4th edition) were recruited and interviewed at 5 Spanish centers to obtain sociodemographic information, health perceptions, depressive symptoms (Geriatric Depression Scale 15-item version), functional ability (Barthel Index), dementia severity (Mini-Mental State Examination), specific QoL (CBS), and generic QoL (World Health Organization Quality of Life-BREF version). Analysis was carried out using classical psychometric methods. Internal consistency reliability for the CBS was good (0.87). A priori hypotheses about the relationship between CBS and the World Health Organization Quality of Life-BREF version psychological domain and Geriatric Depression Scale 15-item version were confirmed, indicating good construct validity. Regarding contrasting groups' differences, CBS scores significantly differentiated between healthy and unhealthy and depressed and nondepressed participants but not between those with mild and moderate dementia. The exploratory factor analysis showed a 5-factor solution, which accounted for 63.9% of the total variance of CBS. This study is the first to report the factor structure of the CBS. These results indicate that CBS is a useful tool in assessing persons with dementia. Replication of these results with larger samples is advised. The Spanish version of the CBS is reliable and valid in persons with mild/moderate dementia who are living at home and with a known caregiver.

Abstract
This study examined change in patient and caregiver ratings of patient quality of life (QOL) over one year in individuals with dementia living in rural and remote settings. The sample was selected from non-institutionalized patients who were assessed at an interprofessional memory clinic. Measures of QOL, cognitive function, depression, and functional ability were completed by the patient. Caregivers completed measures of patient QOL and behavior, and their own burden and distress. At baseline (clinic day) 119 patients and family caregivers were assessed. Thirty-two families had complete data at clinic day and one-year follow-up. There was no significant change in either patient or caregiver-rated QOL over one year. Significant predictors of patient self-rated QOL were patient symptoms of depressed mood and functional ability at clinic day, and symptoms of depressed mood and clinic day QOL at one year. Significant predictors of caregiver-rated patient QOL were caregiver burden, patient functional ability, and symptom severity at clinic day, and caregiver burden at one year. Patient and caregiver ratings of patient QOL were moderately associated, but neither patients nor their caregivers reported a significant change in patient QOL. Changes in QOL over time remain a unique individual experience that cannot be entirely predicted by analytical models.

Abstract
PURPOSE Little research exists to indicate whether the general public can provide proxy health-related quality-of-life (HRQoL) estimates for persons with Alzheimer's disease (AD). We investigated (1) whether the general public can differentiate between mild, moderate, and severe AD and (2) whether the general public's proxy HRQoL estimates are correlated with current health status. METHODS We conducted computer-assisted personal interviews. The computer randomly assigned each participant to read a vignette describing mild, moderate, or severe AD. Participants answered the EQ-5D-5L and Quality-of-life-Alzheimer's Disease (QoL-AD), while imagining living in the health state described in their assigned vignette. Participants also answered the EQ-5D-5L based on their health state at the time of the interview. RESULTS We interviewed 100 participants. EQ-5D-5L utilities were 0.7413 (mild), 0.6159 (moderate), and 0.4456 (severe) (P < 0.001). Mean QoL-AD scores were 32.5 (mild), 24.0 (moderate), and 21.8 (severe) (P < 0.0001 for severe vs. mild, moderate vs. mild; P > 0.05 for severe vs. moderate). Participants' EQ-5D-5L utility scores were weakly correlated (r ≤ 0.28) across both administrations of the instrument. CONCLUSIONS The general public can differentiate between the three stages of AD, and their HRQoL estimates for AD are weakly correlated with their current health status.

Abstract
The objectives of this study are to compare the results of newer performance-based functional assessments in the study of HIV-associated neurocognitive disorders (HAND) and to correlate these functional assessments with specific levels of severity of HAND. One hundred fourteen HIV+ subjects in an existing cohort were evaluated with a medical history, neurological exam, neuropsychological test battery as well as subjective and novel objective measures of functional abilities. Self-reported measures of functional performance included the Karnofsky Performance Scale, a questionnaire for instrumental activities of daily living, and a questionnaire for physical quality of life measures. The newer objective functional performance assessments included the Columbia Medication Management and the San Diego Finances tests. These newer performance-based measures of function were assessed for their ability to predict level of HAND. The two objective measures of functional performance, The Columbia Medication Management Scale and the San Diego Finances Test, were both associated with levels of severity of HAND. The Karnofsky Performance Scale and the questionnaires for role and physical quality of life were subjective measures that were also associated with specific levels of HAND. Newer measures of functional performance can be used to objectively evaluate functional impairment in HAND and validate different levels of HAND.

Abstract
BACKGROUND Cognitive assessment of older persons, particularly those with impairment, is hampered by measurement error and the ethical issues of testing people with dementia. A potential source of valuable information about end-of-life cognitive status can be gained from those who knew the respondent well - mostly relatives or friends. This study tested the association between last cognitive assessment before death and a retrospective informant assessment of cognition. METHODS Data were analyzed from 248 participants from the Medical Research Council Cognitive Function and Ageing Study who were aged 71 to 102 years at death. Late-life cognition was assessed 0 to 8 years before death using the Mini-mental State Examination (MMSE) and the informant measure was taken 0 to 7 years after death using a Retrospective Informant Interview (RInI). RESULTS Zero-inflated Poisson regression showed a strong association between MMSE scores and RInI scores - those scoring 29-30 on the MMSE had a RInI score four times lower than those who scored <18 (p < 0.001). The time between MMSE and death was also a significant predictor with each additional year increasing RInI scores by 12.4% (p < 0.001). The time between death and RInI was only a significant predictor when including measures that were taken four years or more after death. CONCLUSIONS Cognitive scores from retrospective informant interviews are strongly associated with late-life MMSE scores taken close to death. This suggests that the RInI can be used as a proxy measure of cognition in the period leading up to death.

Abstract
Using data from a sample of 169 patients, this study evaluates the acceptability and feasibility of telehealth videoconferencing for preclinic assessment and follow-up in an interprofessional memory clinic for rural and remote seniors. Patients and caregivers are seen via telehealth prior to the in-person clinic, and followed at 6 weeks, 12 weeks, 6 months, one year, and yearly. Patients are randomly assigned to in-person (standard care) or telehealth for the first follow-up, then alternating between the two modes of treatment, prior to 1-year follow-up. On average, telehealth appointments reduce participants' travel by 426 km per round trip. Findings show that telehealth coordinators rated 85% of patients and 92% of caregiversas comfortable or very comfortable during telehealth. Satisfaction scales completed by patient-caregiver dyads show high satisfaction with telehealth. Follow-up questionnaires reveal similar satisfaction with telehealth and in-person appointments, but telehealth is rated as significantly more convenient. Predictors of discontinuing follow-up are greater distance to telehealth, old-age patient, lower telehealth satisfaction, and lower caregiver burden.
