Abstract
Self/informant-report and performance-based instruments are typically used to measure activities of daily living (ADLs) and instrumental activities of daily living (IADLs). Minimal attention has focused on clinician-rated measures. Executive functioning (EF) contributes significantly to functional independence, and the validity of functional status measures has been examined through its relationship to EF scores. The current study used a clinical sample of older U.S. Veterans who completed a neurocognitive evaluation (n = 266). The psychometric properties of a novel, clinician-rated Functional Status Interview (FSI) and its relationship to EF measures, including the Frontal Assessment Battery (FAB) and Trail Making Test (TMT-A and TMT-B), were explored. Two FSI factors (IADL and ADL) emerged with all items loading strongly onto the subscales as predicted. EF correlated strongly with IADL but had small to medium correlations with ADL. In regression models that controlled for sociodemographic variables, all EF measures uniquely contributed to the IADL model, but only FAB and TMT-A contributed to the model for ADL. Notably, results may have been limited by prominent floor effects on TMT-B. Overall, the FSI is a promising measure with demonstrated content validity. Thus, there is preliminary support for clinicians to incorporate multiple sources of information to rate functional status using the FSI.

Abstract
Literature suggests that dementia and, more generally, cognitive impairment affect the capacity to carry out activities of daily living (ADL) in aging. However, it is important to decipher the weight of specific cognitive domains and neurodegenerative profiles mainly related to ADL difficulties. A meta-analysis was conducted to investigate the nature and strength of the association between cognitive functioning and ADL in healthy older adults, mild cognitive impairment (MCI), and dementia. A comprehensive search of the PubMed, PsycINFO (PROQUEST), and Scopus databases for cross-sectional or longitudinal studies up until December 2022. Our meta-analytic results revealed that: overall, instrumental ADL (IADL) showed a significant association with executive functioning, in particular, abstraction ability/concept formation, set-shifting, and processing speed/complex attention/working memory, regardless of type of participants (i.e., healthy older adults, MCI, and dementia); whereas ADL (both basic ADL, BADL, and IADL) significantly correlated with global cognitive functioning and long-term verbal memory, with a moderator effect of clinical condition (e.g., increasing ES based on the level of cognitive impairment). Moreover, visuospatial and language abilities significantly correlated with ADL, mainly when performance-based tasks were used for ADL assessment. These findings emphasize the importance of neuropsychological assessment in aging to early identify people most at risk of functional decline and shed light on the need to consider specific cognitive abilities in rehabilitation programs.

Abstract
OBJECTIVE Self- and informant-ratings of functional abilities are used to diagnose mild cognitive impairment (MCI) and are commonly measured in clinical trials. Ratings are assumed to be accurate, yet they are subject to biases. Biases in self-ratings have been found in individuals with dementia who are older and more depressed and in caregivers with higher distress, burden, and education. This study aimed to extend prior findings using an objective approach to identify determinants of bias in ratings. METHOD Participants were 118 individuals with MCI and their informants. Three discrepancy variables were generated including the discrepancies between (1) self- and informant-rated functional status, (2) informant-rated functional status and objective cognition (in those with MCI), and (3) self-rated functional status and objective cognition. These variables served as dependent variables in forward linear regression models, with demographics, stress, burden, depression, and self-efficacy as predictors. RESULTS Informants with higher stress rated individuals with MCI as having worse functional abilities relative to objective cognition. Individuals with MCI with worse self-efficacy rated their functional abilities as being worse compared to objective cognition. Informant-ratings were worse than self-ratings for informants with higher stress and individuals with MCI with higher self-efficacy. CONCLUSION This study highlights biases in subjective ratings of functional abilities in MCI. The risk for relative underreporting of functional abilities by individuals with higher stress levels aligns with previous research. Bias in individuals with MCI with higher self-efficacy may be due to anosognosia. Findings have implications for the use of subjective ratings for diagnostic purposes and as outcome measures.

Abstract
INTRODUCTION Impaired cognition and instrumental activities of daily living (iADL) are key diagnostic features of dementia; however, few studies have compared trajectories of cognition and iADL. METHODS Participants from the IDEAL study comprised 1537, 1183, and 851 people with dementia, and 1277, 977, and 749 caregivers at baseline, 12 and 24 months, respectively. Addenbrooke's Cognitive Examination-III and Functional Activities Questionnaire were used to measure cognition and iADL, respectively. Scores were converted to deciles. RESULTS Self-rated iADL declined on average by -0.08 (-0.25, 0.08) decile points per timepoint more than cognition. Informant-rated iADL declined on average by -0.31 (-0.43, -0.18) decile points per timepoint more than cognition. DISCUSSION Cognition and self-rated iADL declined at a similar rate. Informant-rated iADL declined at a significantly greater rate than cognition. Therefore, either cognition and perceived iADL decline at different rates or informants overestimate increasing iADL difficulties compared to both cognition and self-ratings. HIGHLIGHTS Self-ratings of the degree of functional difficulties were consistent with cognition Decline in self-rated everyday activities was consistent with cognitive decline Informant-ratings of everyday activities declined more than cognition.

Abstract
BACKGROUND Cognitive impairments affect functional ability in people with dementia. Cognitive rehabilitation (CR) is a personalised, solution-focused approach that aims to enable people with mild-to-moderate dementia to manage everyday activities and maintain as much independence as possible. OBJECTIVES To evaluate the effects of CR on everyday functioning and other outcomes for people with mild-to-moderate dementia, and on outcomes for care partners. To identify and explore factors that may be associated with the efficacy of CR. SEARCH METHODS We searched the Cochrane Dementia and Cognitive Improvement Group Specialised Register, which contains records from MEDLINE, EMBASE, CINAHL, PsycINFO, LILACS, and other clinical trial databases, and grey literature sources. The most recent search was completed on 19 October 2022. SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing CR with control conditions and reporting relevant outcomes for the person with dementia and/or the care partner. DATA COLLECTION AND ANALYSIS We extracted relevant data from published manuscripts and contacted trial authors if necessary. Within each of the comparisons, we pooled data for each outcome of interest and conducted inverse-variance, random-effects meta-analyses. We evaluated the certainty of the evidence using GRADEpro GDT. MAIN RESULTS We identified six eligible RCTs published in English between 2010 and 2022, which together included 1702 participants. The mean age of participants ranged from 76 to 80 and the proportion of male participants was between 29.4% and 79.3%. Most participants, in the studies where the type of dementia was reported, had a diagnosis of Alzheimer's disease (AD; n = 1002, 58.9% of the whole sample, 81.2% of the participants for whom the specific diagnosis was reported). Risk of bias in the individual studies was relatively low. The exception was a high risk of bias in relation to blinding of participants and practitioners, which is not usually feasible with psychosocial interventions. Our primary outcome of everyday functioning was operationalised in the included studies as goal attainment in relation to activities targeted in the intervention. For our main comparison of CR with usual care, we pooled data for goal attainment evaluated from three perspectives (self-rating of performance, informant rating of performance, and self-rating of satisfaction with performance) at end of treatment and at medium-term follow-up (3 to 12 months). We could also pool data at these time points for 20 and 19 secondary outcomes respectively. The review findings were strongly driven by one large, high-quality RCT. We found high-certainty evidence of large positive effects of CR on all three primary outcome perspectives at the end of treatment: participant self-ratings of goal attainment (standardised mean difference (SMD) 1.46, 95% confidence interval (CI) 1.26 to 1.66; I2 = 0%; 3 RCTs, 501 participants), informant ratings of goal attainment (SMD 1.61, 95% CI 1.01 to 2.21; I2 = 41%; 3 RCTs, 476 participants), and self-ratings of satisfaction with goal attainment (SMD 1.31, 95% CI 1.09 to 1.54; I2 = 5%; 3 RCTs, 501 participants), relative to an inactive control condition. At medium-term follow-up, we found high-certainty evidence showing a large positive effect of CR on all three primary outcome perspectives: participant self-ratings of goal attainment (SMD 1.46, 95% CI 1.25 to 1.68; I2 = 0%; 2 RCTs, 432 participants), informant ratings of goal attainment (SMD 1.25, 95% CI 0.78 to 1.72; I2 = 29%; 3 RCTs, 446 participants), and self-ratings of satisfaction with goal attainment (SMD 1.19, 95% CI 0.73 to 1.66; I2 = 28%; 2 RCTs, 432 participants), relative to an inactive control condition. For participants at the end of treatment we found high-certainty evidence showing a small positive effect of CR on self-efficacy (2 RCTs, 456 participants) and immediate recall (2 RCTs, 459 participants). For participants at medium-term follow-up we found moderate-certainty evidence showing a small positive effect of CR on auditory selective attention (2 RCTs, 386 participants), and a small negative effect on general functional ability (3 RCTs, 673 participants), and we found low-certainty evidence showing a small positive effect on sustained attention (2 RCTs, 413 participants), and a small negative effect on memory (2 RCTs, 51 participants) and anxiety (3 RCTs, 455 participants). We found moderate- and low-certainty evidence indicating that at the end of treatment CR had negligible effects on participant anxiety, quality of life, sustained attention, memory, delayed recall, and general functional ability, and at medium-term follow-up on participant self-efficacy, depression, quality of life, immediate recall, and verbal fluency. For care partners at the end of treatment we found low-certainty evidence showing a small positive effect on environmental aspects of quality of life (3 RCTs, 465 care partners), and small negative effects of CR on level of depression (2 RCTs, 32 care partners) and on psychological wellbeing (2 RCTs, 388 care partners). For care partners at medium-term follow-up we found high-certainty evidence showing a small positive effect of CR on social aspects of quality of life (3 RCTs, 436 care partners) and moderate-certainty evidence showing a small positive effect on psychological aspects of quality of life (3 RCTs, 437 care partners). We found moderate- and low-certainty evidence at the end of treatment that CR had negligible effects on care partners' physical health, psychological and social aspects of quality of life, and stress, and at medium-term follow-up for the physical health aspect of care partners' quality of life and psychological wellbeing. AUTHORS' CONCLUSIONS CR is helpful in enabling people with mild or moderate dementia to improve their ability to manage the everyday activities targeted in the intervention. Confidence in these findings could be strengthened if more high-quality studies contributed to the observed effects. The available evidence suggests that CR can form a valuable part of a clinical toolkit to assist people with dementia in overcoming some of the everyday barriers imposed by cognitive and functional difficulties. Future research, including process evaluation studies, could help identify avenues to maximise CR effects and achieve wider impacts on functional ability and wellbeing.

Abstract
OBJECTIVE To examine predictors of informant-reported everyday functioning in mild cognitive impairment (MCI) and relations between everyday function and conversion to dementia. METHODS Informants of participants (n = 2614) with mild cognitive impairment (MCI) were administered the Functional Activities Questionnaire (FAQ). Changes in dimensions of functional ability as determined by an exploratory factor analysis (EFA) were examined over 3 years and participant predictors of change were examined using multilevel modeling (MLM). RESULTS The FAQ consisted of 3 factors, multistep, finance, and memory/orientation daily tasks. Impairment in memory/orientation tasks was significantly higher than impairment in multistep tasks. Worse functioning was associated with greater depression, worse memory, worse speed/EF, higher years of education and identifying as White. There was variability in some of these associations with different FAQ factors. Impairments in financial and memory/orientation daily tasks predicted follow-up conversion to dementia. CONCLUSIONS Depression, speed/EF, and memory are consistently associated with domains of everyday functioning. Race, education, and age may be more variability associated with everyday functioning. Specific attention should be paid to subtle declines in the financial and memory/orientation domains as they may uniquely predict future dementia development. Depression may be a modifiable risk factor associated with functional impairment over time.

Abstract
BACKGROUND Though not originally developed for this purpose, the Healthy Aging Brain Care Monitor (HABC-M) seems a valuable instrument for assessing anosognosia in Alzheimer's disease (AD). OBJECTIVES Our study aimed at 1) investigating the validity of the HABC-M (31 items), and its cognitive, psychological, and functional subscales, in discriminating AD patients from controls; 2) exploring whether the HABC-M discrepancy scores between the self-reports of patients/controls in these different domains and the respective ratings provided by their caregivers/informants correlate with an online measure of self-awareness; 3) determining whether the caregiver burden level, also derived from the HABC-M, could add additional support for detecting anosognosia. METHODS The HABC-M was administered to 30 AD patients and 30 healthy controls, and to their caregivers/informants. A measure of online awareness was established from subjects' estimation of their performances in a computerized experiment. RESULTS The HABC-M discrepancy scores distinguished AD patients from controls. The cognitive subscale discriminated the two groups from the prodromal AD stage, with an AUC of 0.88 [95% CI: 0.78;0.97]. Adding the caregiver burden level raised it to 0.94 [0.86;0.99]. Significant correlations between the HABC-M and online discrepancy scores were observed in the patients group, providing convergent validity of these methods. CONCLUSIONS The cognitive HABC-M (six items) can detect anosognosia across the AD spectrum. The caregiver burden (four items) may corroborate the suspicion of anosognosia. The short-hybrid scale, built from these 10 items instead of the usual 31, showed the highest sensitivity for detecting anosognosia from the prodromal AD stage, which may further help with timely diagnosis.

Abstract
BACKGROUNDS Subjective cognitive decline (SCD), one of the important clinical indicators for preclinical Alzheimer's disease (AD), is primarily defined as self-perceived cognitive decline without objective evidence for cognitive impairment. However, the accuracy of their self-evaluation of cognition is unclear. This study sought to investigate the capacity for self-evaluation of own cognitive performance in SCD by applying an objective metamemory paradigm. METHODS 147 individuals with SCD were classified into four subgroups by their subjective feeling of worse performance than peers or not (P+/-) and whether they have objectively slight cognitive impairment compared to normative data (S+/-). Metamemory scores, the amplitude of the low-frequency fluctuation (ALFF), fractional low-frequency fluctuation amplitude (fALFF), and cortical thickness were compared among four subgroups. Partial correlations between neuropsychological scores and neuroimaging measures were examined, controlling for age, sex, and education years. RESULTS SCD S+P- showed the worst performance in short-term delayed recall and the worst metamemory performance, indicated by the highest value in the degree of confidence of short-term delayed recall (DOC-N4) and long-term cued recall (DOC-N6) and the worst value in relative accuracy of judgments of short-term delayed recall (ROJ-N4). ALFF values in the bilateral superior medial frontal and olfactory cortices and the left superior orbitofrontal gyrus cortex were significantly higher in SCD P- compared with SCD P+ groups (all P < 0.05, FWE-corrected, cluster-wise level). A significant S × P interaction effect in the left hippocampus and middle cingulate cortex was found for the fALFF signals (all P < 0.05, FWE-corrected, cluster-wise level). Significant interaction and main effects on cortical thickness were reported. The parahippocampal and posterior cingulate cortices were significantly decreased in SCD S+P- (all P < 0.05). CONCLUSION SCD S+P- showed the worst episodic memory performance, altered metamemory capacity (overconfidence and less accuracy of judgment), and altered neuroimaging measures, though they had feelings of similar performance with peers. Our results indicate that metamemory capacity is affected in a subtype of SCD with reduced cortical thickness and intensity of regional spontaneous activity in key areas for metamemory processing.

Abstract
INTRODUCTION Discrepancy scores reflecting the difference between parallel ratings made by people living with dementia (PwD) in the mild-to-moderate stages and by their informants provide a way to investigate awareness of functional ability in relation to activities of daily living (ADL). METHODS Two measures of ADL (Functional Activities Questionnaire; Dependence Scale) were completed by 1,227 PwD and their informants in the IDEAL cohort study baseline assessment. Self-rated and informant-rated scores were used to calculate discrepancies, which were used as an indicator of awareness of functional ability. Smaller discrepancy scores were considered to reflect greater awareness on the part of PwD. PwD completed questionnaires on depression, personality, comorbidities, neuropsychiatric symptoms, and completed a measure of cognition. Informants provided ratings of stress. Univariable and multiple regressions were used to investigate factors related to ADL discrepancy. RESULTS A similar pattern of associations were found for both ADL discrepancy scores. Smaller discrepancy scores were associated with higher levels of depression, higher neuroticism, fewer neuropsychiatric symptoms, higher comorbidity, lower carer stress, and receipt of less than 1 hour of care per day from the informant. DISCUSSION/CONCLUSION There was a clear pattern of factors that were associated with greater awareness for both measures of functional ability. These factors associated with smaller discrepancy scores could be used to identify PwD who might benefit from targeted interventions to support their independence.

Abstract
Objective Previous research shows that depression and personality are independently associated with self- and informant-reports of the ability to perform instrumental activities of daily living (IADLs). However, less is known about the association between depression and personality and performance-based measures of IADLs. We aimed to determine how depression and personality predict self-and informant-reports of IADL compared to performance-based measures of IADLs in a sample of older adults with normal cognition (NC) and Mild Cognitive Impairment (MCI). Methods Participants consisted of 385 older adults with NC (n = 235), or a diagnosis of MCI (n = 150), aged between 76 and 99-years from the Sydney Memory and Ageing Study. Participants underwent comprehensive neuropsychological and clinical assessments to determine global cognition and clinical diagnoses. Personality traits were measured by the NEO Five-Factor Inventory (NEO-FFI) and depression by the Geriatric Depression Scale (GDS). Subjective IADLs were self- and informant-reported Bayer Activities of Daily Living (B-ADL) scales and objective IADL was the Sydney Test of Activities of Daily Living in Memory Disorders (STAM). Linear regressions examined the relationship between depression and personality and the three types of IADL measures, controlling for all covariates and global cognition. Results Participant-reported IADL, although associated with global cognition, was more strongly associated with GDS and NEO-FFI scores (conscientiousness and neuroticism). Informant-reported IADL was strongly associated with both global cognition and participants' GDS scores. STAM scores were not associated with participants' GDS or NEO-FFI scores; instead, they were predicted by demographics and global cognition. Conclusion These results suggest that performance-based measures of IADL may provide more objective and reliable insight into an individual's underlying functional ability and are less impacted by the participants' mood and personality compared to subjectively reported IADL. We argue that performance-based IADL measures are preferable when trying to accurately assess everyday functional ability and its relationship to cognitive status. Where performance-based measures are not available (e.g., in some clinical settings), informant ratings should be sought as they are less influenced by the participant's personality and mood compared to self-reports.

Abstract
INTRODUCTION Although there is some evidence that different symptoms of depression have differential effects on cognition in older adults, these relationships remain understudied in older adults with mild cognitive impairment (MCI). METHOD Older adults (>50 years old) were classified as having MCI by Alzheimer's Disease Research Centers (ADRCs). Exploratory factor analyses and factor mixture modeling were used to determine depression symptom classes. Classes were then compared across different domains of cognition (i.e., memory, attention, language, and executive function) and informant-rated everyday function. RESULTS Analyses revealed six, distinct symptom classes (i.e., somatic symptoms, severely depressed, anhedonic symptoms, cognitive symptoms, minimally depressed, and low life satisfaction symptoms). Classes significantly varied on all measures of cognition and everyday function. In particular, the anhedonic class often showed the most substantial decline (on par with the severely depressed class), while the low life satisfaction class often showed the least (on par with the minimally depressed class). CONCLUSIONS To our knowledge, this is the first study to examine the relationship between depression symptom profiles and cognitive and everyday function in those with MCI. Our findings show that depression symptoms greatly differ in their associations with cognitive and everyday function. It may be beneficial for clinicians to specifically note if patients with MCI are reporting anhedonic and somatic symptoms of depression specifically.

Abstract
This study investigated associations between time processing ability (TPA), daily time management (DTM), and dementia severity. Persons with dementia (PwDs) (n = 53) and their significant others (n = 49) participated in this cross-sectional study. Bivariate analyses were used to investigate associations between TPA and DTM and the dementia severity. Linear regression models were used to further predict the contribution of the subtests in the Mini Mental State Examination (MMSE) for TPA results. The results showed significant correlations between TPA and dementia severity, where visuospatial functions were the most highly correlated. TPA also showed a significant correlation to proxy-rated DTM. In addition, proxy-rated DTM was significantly correlated with dementia severity and PwDs' own self-ratings of their DTM. Knowledge of the association between TPA, dementia severity, and visuospatial functions can enable early detection of TPA impairments. For a comprehensive assessment of TPA and DTM, objective measures should be used in combination with self-ratings and proxy-ratings. The findings can be used in clinical research and healthcare settings to develop methods to compensate for impaired TPA and support DTM in PwDs.

Abstract
BACKGROUND Negative impacts of the COVID-19 pandemic on people with dementia have been widely-documented, but most studies have relied on carer reports and few have compared responses to information collected before the pandemic. OBJECTIVE We aimed to explore the impact of the pandemic on community-dwelling individuals with mild-to-moderate dementia and compare responses with pre-pandemic data. METHODS During the second wave of the pandemic, we conducted structured telephone interviews with 173 people with dementia and 242 carers acting as informants, all of whom had previously participated in the IDEAL cohort. Where possible, we benchmarked responses against pre-pandemic data. RESULTS Significant perceived negative impacts were identified in cognitive and functional skills and ability to engage in self-care and manage everyday activities, along with increased levels of loneliness and discontinuity in sense of self and a decline in perceived capability to 'live well'. Compared to pre-pandemic data, there were lower levels of pain, depression, and anxiety, higher levels of optimism, and better satisfaction with family support. There was little impact on physical health, mood, social connections and relationships, or perceptions of neighborhood characteristics. CONCLUSION Efforts to mitigate negative impacts of pandemic-related restrictions and restore quality of life could focus on reablement to address the effects on participation in everyday activities, creating opportunities for social contact to reduce loneliness, and personalized planning to reconnect people with their pre-COVID selves. Such efforts may build on the resilience demonstrated by people with dementia and carers in coping with the pandemic.

Abstract
Quality of life (QoL) includes complex interactions between objective and subjective factors. Through structural equation modeling, we analyzed people with Alzheimer disease (PwAD) and carers' ratings to identify the factors associated with PwAD QoL. We included 264 PwAD and their carers. Model 1, carers' ratings of PwAD QoL, showed a bidirectional association with worse depressive symptoms, lower functionality, and impairment on awareness being linked. These variables were associated with burden and all of them directly affecting carers' ratings of PwAD QoL. Model 2, PwAD self-reported QoL, had the same bidirectional associations among the same variables with all of them influencing PwAD self-reported QoL. However, the interpretations of these similar associations should be different. The path analysis increased the understanding of the relationship between QoL and cognition, functionality, mood, awareness, and burden. Our findings bring together a number of consistent predictors and confirm their different effects in PwAD and carers' point of view about QoL.

Abstract
BACKGROUND AND OBJECTIVES Persons with dementia experience behavioral symptoms, such as agitation and repeating questions, which have been reported as one of the most burdensome and stressful aspects of providing care for dementia caregivers. However, no published studies have assessed the subjective experience of behavioral symptoms and distress from people with dementia. RESEARCH DESIGN AND METHODS The current pilot study examined the feasibility of people with dementia providing self-reported behaviors and behavioral-related distress. Data from a larger, on-going research study was used consisting of people with mild to moderate dementia (n = 12) residing in a long-term memory care facility. RESULTS Participants were able to provide reliable (∝=.91) self-reported data concerning their own behaviors and behavioral-related distress with variability among responses. The most frequently self-reported behaviors included agitation (66.7%) and complaining/criticizing things (58.3%) while the least reported behaviors were refusing to be left alone (8.3%) and yelling/swearing (8.3%). The highest behavioral distress reported was agitation (58.3%) while the least was wandering (8.3%). DISCUSSION AND IMPLICATIONS Understanding the subjective, perceived experience of people with dementia provides valuable information on the illness experience. Additional research is needed to examine the role and impact of self-reported behaviors and the resulting behavioral- related distress on outcomes of well-being. Subjective reports of behavioral-related distress could predict well-being, above and beyond that of traditional objective measures, creating the potential for novel non-pharmacological intervention development for people with dementia.

Abstract
BACKGROUND Awareness of functional status may underlie specific profiles and differences related to stage severity in individuals with Alzheimer's disease (AD). OBJECTIVE This study aimed to assess self-reported experiences of awareness of functional activity in people with mild and moderate AD. METHODS This is a mixed methods approach. The qualitative part was conducted through semi-structured interviews concerning the experiences and awareness of deficits in 38 older adults with mild or moderate AD. The quantitative approach included a comparison between groups with regard to concerns of awareness and clinic and demographic data. RESULTS Impairment on awareness of disease and awareness of functional deficits was observed even in the mild stages of AD. There was also a noticeable progression of impairments of both kinds of awareness from mild to moderate stage of disease. The majority of participants with mild and moderate AD were partially aware of their functional deficits. Both groups of participants reported some negative impact; however, they were not able to entirely describe their functional status. Also, deficits to recognize the need for help with hygiene and general tasks were observed. Significant differences were found in awareness of need for help with general tasks and awareness of need for help with hygiene tasks. CONCLUSION People with mild and moderate AD may describe their aware of the disease better than specific functional deficits, and most of them can provide some reports concerning to the impact of the disease.

Abstract
INTRODUCTION Anosognosia is a common but underrated symptom in dementia and has significant impact on both patients and caregivers. A proper evaluation of anosognosia is therefore desirable. There are three common methods to determine anosognosia: (1) clinical rating, (2) patient-caregiver discrepancies, and (3) prediction of performance discrepancies. Each of them includes different instruments. This review gives an overview of the current instruments used for the assessment of anosognosia in patients with dementia and aims to determine the most suitable instrument for routine use in clinical practice. METHODS A search of the literature in PubMed was performed. Furthermore, electronic databases (PsycINFo, ClinicalKey, and Cochrane Library) and reference lists were searched for additional articles. RESULTS Forty-six articles were included in this study, comprising 10 clinical rating instruments, 25 patient-caregiver discrepancy instruments, and 14 prediction-performance discrepancy instruments. For every publication, the aims of the study, the included population, the assessment instrument used, the assessed domains, and the psychometric properties of the assessment instruments are described. CONCLUSIONS Currently, there is no consensus on the most suitable method to determine anosognosia in dementia. We recommend the Clinical Insight Rating scale and the Abridged Anosognosia Questionnaire-Dementia as the most appropriate for routine use in clinical practice.

Abstract
OBJECTIVES The main aim of the study was to compare the rates of mortality in older adults with and without functional unawareness (FU). We also tested a possible interaction effect between levels of awareness and education, as a single cognitive reserve proxy, on mortality. STUDY DESIGN The study design is a longitudinal population-based cohort study. METHODS The Neurological Disorders in Central Spain is epidemiological study to detect main age-associated conditions in people aged 65 years and older. Participants were collected from updated population-based registers of residents in three areas of central Spain. Awareness of functional limitations was established in accordance with the discrepancy between two sources of information on functional impairments: reliable informants versus the participants themselves. Three mutually exclusive groups were formed, namely, Functional Limitation Complaints (FCs), FU, and Functional Awareness (FA). Cox's regression models, adjusted by different covariates, were used to calculate the risk of mortality for each group at 5-year follow-up (vs. reference group without limitations). RESULTS Of 1818 selected individuals, 229 (12.5%) showed FA, 254 (13.9%) showed FC, and 96 (5%) were classified as FU. All these groups showed an increased risk of mortality at 5-year follow-up [adjusted hazard ratio (HR) for FC < FU < FA]. However, the association of FU with mortality remained significant only for highly educated individuals. CONCLUSIONS Functional impairment was associated with increased mortality rates, regardless of the presence of unawareness. This study extends the role of education in modulating the symptoms and prognosis of individuals at very mild or preclinical dementia stages.

Abstract
OBJECTIVE Primarily, to investigate the association between informant report and objective performance on specific financial capacity (FC) tasks by adults with chronic, moderate to severe acquired brain injury, and to examine the nature of misestimates by the informants. DESIGN Cross-sectional design. SETTING A postacute, community-based rehabilitation center. PARTICIPANTS Data were obtained from 22 chronic acquired brain injury (CABI) adults, mean age of 46.6 years (SD = 8.67), mean years of education of 13.45 years (SD = 2.15), with moderate to severe acquired brain injury (86% had traumatic brain injury), with a mean postinjury period of 17.14 years (SD = 9.5). Whereas the CABI adults completed the Financial Competence Assessment Inventory interview-a combination of self-report and performance-based assessment, 22 informants completed a specifically designed parallel version of the interview. RESULTS Pearson correlations and 1-sample t tests based on the discrepancy scores between informant report and CABI group's performance were used. The CABI group's performance was not associated with its informant's perceptions. One-sample t tests revealed that informants both underestimated and overestimated CABI group's performance. CONCLUSIONS Results indicate lack of correspondence between self- and informant ratings. Further investigation revealed that misestimations by informants occurred in contrary directions with CABI adults' performance being inaccurately rated. These findings raise critical issues related to assuming that the informant report can be used as a "gold standard" for collecting functional data related to financial management, and the idea that obtaining objective data on financial tasks may represent a more valid method of assessing financial competency in adults with brain injury.

Abstract
BACKGROUND Subjective memory complaints (SMCs) are incorporated into the diagnosis of mild cognitive impairment (MCI) and neurodegenerative dementias; however, the relative frequency of SMCs in cognitively intact older adults and those with different types of dementia is poorly understood. Similarly, the concordance between self- versus informant-reported SMCs has not been compared across different diagnostic groups. OBJECTIVE This study aimed to evaluate the frequency of self-reported (Objective 1) and informant-reported (Objective 2) SMCs in cognitively intact adults or those diagnosed with MCI or a neurodegenerative dementia. Agreement between participant and informant complaints was also evaluated (Objective 3). METHODS Baseline evaluation data were drawn from 488 participants (Mage = 70.49 years; Medu = 15.62 years) diagnosed as cognitively intact, non-amnestic MCI, amnestic single domain MCI, amnestic multi-domain MCI, possible/probable Alzheimer's disease, dementia with Lewy bodies, or frontotemporal dementia. Participants and their informants completed the Memory Assessment Clinic Questionnaire. RESULTS One-way ANCOVAs controlling for age, education, and depression revealed no group differences in severity of self-reported SMCs. In contrast, informant memory ratings followed the expected clinical pattern, with comparable and most impaired ratings given to participants with any dementia diagnosis, followed by those with any MCI diagnosis, followed by cognitively intact participants. There was inconsistent agreement between self- and informant-reported SMC ratings in any of the impaired groups. CONCLUSIONS Given greater diagnostic specificity and internal consistency of informant report, clinicians should weigh this information more heavily than self-report in the diagnostic process.

Abstract
OBJECTIVES The objectives of the study are to investigate how different levels of functional ability relate to quality of life, well-being, and satisfaction with life, conceptualised as reflecting capability to "live well" in people with dementia. METHODS/DESIGN Participants were 1496 people with mild-to-moderate dementia and 1188 informants who completed baseline assessments in the Improving the experience of Dementia and Enhancing Active Life (IDEAL) cohort study. Total self-rated and informant-rated scores on the Functional Activities Questionnaire were split into six ability levels to monitor how poorer functioning impacts the ability to live well. We also investigated the potential influence of sociodemographic and diagnostic variables, depression, cognition, and carer stress. RESULTS Multivariate multiple regression models found that people with dementia who had the greatest functional impairment according to self-ratings and informant ratings had poorer living well scores than those with the least functional impairment. Sociodemographic and diagnostic factors and cognition had little impact on effect sizes. For self-ratings, depression attenuated the relationship between functional ability and living well, whereas carer stress attenuated informant ratings. CONCLUSIONS People with dementia with the least functional impairments had greater capability to live well than those with the most functional impairment. Even subtle perceived difficulties in functional ability had a detrimental effect on the ability of people with dementia to live well. Depression in people with dementia and carer stress in informants influenced these associations, and therefore, these factors should be routinely included in future research studies and clinical assessments.

Abstract
BACKGROUND Impaired cognition and activities of daily living (ADL) are core symptoms of Alzheimer's disease (AD), but their relationship is unclear. OBJECTIVES To explore relationships between cognitive domains and functional ability during 5-year follow-up in persons with AD. METHODS We analyzed ALSOVA study data from 236 individuals with very mild or mild AD at baseline. The CERAD Neuropsychological Battery (CERAD-NB) was used as a cognitive measure and Alzheimer's Disease Cooperative Study ADL (ADCS-ADL) as a functional measure, analyzing the IADL and BADL sub-scores separately. Annual regression models and linear mixed-effect models (LMMs) covering a 5-year follow-up period were used. RESULTS Annually, the CERAD-NB total and especially Verbal Fluency, Clock Drawing, and Constructional Praxis were associated with the total ADCS-ADL and IADL scores increasingly yet modestly, and to a lesser extent the BADL score. In the LMMs, the same measures and MMSE were associated with ADL. CONCLUSION Measures of executive function and visuoconstructive skills appear to be associated with caregiver-interview based ADL measure during the progression of AD.

Abstract
UNLABELLED ABSTRACTObjectives:Finance management skills deteriorate early on in dementia, and can influence the ability to maintain control over personal affairs. The aim of this study was to assess the contributions of different types of cognition and motor functioning to finance management. DESIGN Cross-sectional analysis using secondary data. SETTING Community living. PARTICIPANTS Baseline data from the Uniform Data Set from the National Alzheimer's Coordinating Centers were obtained and extracted up until December 2016. MEASUREMENTS Measures on everyday functioning (Functional Assessment Questionnaire) and cognition (memory, executive functioning, and language), the Clinical Dementia Rating scale, and questions on Parkinsonian motor symptoms (gait disturbance, falls, tremors, and slowness) were included. Data were analyzed using bivariate correlation and linear regression analyses. RESULTS A total of 9,383 participants were included in the analysis (Alzheimers disease (AD) = 8,201; behavioral variant fronto-temporal dementia (bvFTD) = 796; Dementia with Lewy Bodies (DLB) = 386). Cognition and motor functioning varied significantly across AD, bvFTD, and DLB, with poorer motor functioning and poorer finance management skills in DLB than in AD and bvFTD. In the regression models, slowness, verbal fluency, executive functioning, and language, followed by age, gender, and diagnosis accounted for 13.8% of the variation in managing bills, and for 11.4% of the variation in managing taxes. CONCLUSION Maintaining finance management abilities for as long as possible is important for people with dementia, to avoid potential financial exploitation. Findings from this study highlight avenues to pursue to delay deterioration in managing bills and taxes, and help maintain financial control.

Abstract
This State of the Science Commentary responds to the preliminary recommendation from the National Research Summit on Dementia Care, Services and Supports for Persons with Dementia and Their Caregivers to develop and identify a broad array of outcome measures (objective and subjective) that are meaningful to different stakeholders. Five significant measurement challenges that nurse scientists confront when conducting research with individuals with cognitive impairment are presented: (a) assessment of subjective memory complaints; (b) validity of self-report; (c) ecological validity of cognitive performance measures; (d) use of biomarkers (neuroimaging) for describing the biological dynamics of symptoms; and (e) effect of high variability in measurement on statistical significance. Methods for addressing these challenges are offered. [Res Gerontol Nurs. 2019; 12(1):7-15.].

Abstract
OBJECTIVE To assess the prevalence, antecedents, and consequences of unawareness of memory impairment in dementia. METHOD Persons (n = 1,862) from a geographically defined community without dementia at enrollment subsequently underwent clinical classification (248 with dementia, 611 with mild cognitive impairment, 1,003 with no cognitive impairment), memory testing, and self-appraisal of memory. Memory performance was regressed on self-appraised memory, and the residuals served as an index of memory awareness. After clinical classification, participants completed brief cognitive testing at 3-year intervals for up to 15 years. RESULTS When unawareness was defined as a score at or below thresholds ranging from the 15th to 25th percentiles, it was more common in dementia (67%-83%) and mild cognitive impairment (15%-33%) than in no cognitive impairment (2%-6%; all p < .001). A continuous measure of awareness (M = 0.00, SD = 0.61) was reduced by 0.37-unit in mild cognitive impairment (SE = 0.04, p < .001) and 1.04-unit in dementia (SE = 0.06), p < .001) compared with those without cognitive impairment, and these associations were weaker in Black persons than White persons (estimate for dementia by race = 0.37, SE = 0.12, p = .003; estimate for mild cognitive impairment by race = 0.30, SE = 0.08, p < .001). Higher premorbid neuroticism was associated with better memory awareness in dementia. Higher memory awareness was not related to mortality in mild cognitive impairment or dementia but had a marginal association with slower cognitive decline in mild cognitive impairment. CONCLUSIONS Unawareness of memory impairment is a common manifestation of dementia, particularly in White persons, but is not strongly related to adverse disease outcomes.

Abstract
OBJECTIVES Educational initiatives can improve care delivery and the experience of living in residential aged care for people with dementia. This review aimed to determine the impact of nurse and care staff education on measures of functional ability and quality of life for older people with dementia living in care homes. DESIGN Systematic review. DATA SOURCES Search of on-line databases in English between January 2000 and January 2017. REVIEW METHODS Three reviewers used data extraction and critical appraisal tools of the Joanna Briggs Institute to determine methodological quality of research. RESULTS AND CONCLUSION Thirty-two studies met the initial inclusion criteria and 13 were retrieved for full appraisal. There was limited impact of nurse and care staff education on residents' agitation, anxiety, mood and quality of life. The most consistent improvement in functional ability due to education may be in the execution of activities of daily living. More successful programs included multi-faceted components (e.g. hands on support, clinical auditing) in conjunction with didactic teaching. There is a need for more rigorous and well-designed studies to test interventions.

Abstract
Background Informant-based rating scales are widely used in dementia but patients' and caregivers' features influence the final scoring. We aimed to evaluate the role of patient- and caregiver-related factors in a caregiver rated Global Deterioration Scale (GDS) score in a sample of Greek patients with dementia. Methods We included 194 patients with dementia and 194 caregivers/family relatives; Mini-Mental State Examination (MMSE); Neuropsychiatric Inventory (NPI); Katz Index of Activities of Daily Living (K-IADL) were administered to (a) patients and Center for Epidemiologic Studies-Depression (CES-D) Scale; Zarit Burden Interview (ZBI) to (b) caregivers. Participants' demographics and patients' and caregivers' characteristics were entered into a 3-block regression analysis. Results The final model explained 55% of the total variance of the caregiver assessed GDS score. The following variables significantly contributed to the final model: MMSE (β=-0.524); K-IADL (β=-0.264); ZBI (β=0.145). Conclusion We herein confirm the contribution of patients' cognitive and functional status and caregivers' burden in caregiver rated GDS scoring irrespective of demographic-related characteristics.

Abstract
Patients with Alzheimer's Disease (AD) and Mild Cognitive Impairment (MCI) may present anosognosia for their cognitive deficits. Three different methods have been usually used to measure anosognosia in patients with AD and MCI, but no studies have established if they share similar neuroanatomical correlates. The purpose of this study was to investigate if anosognosia scores obtained with the three most commonly used methods to assess anosognosia relate to focal atrophy in AD and MCI patients, in order to improve understanding of the neural basis of anosognosia in dementia. Anosognosia was evaluated in 27 patients (15 MCI and 12 AD) through clinical rating (Clinical Insight Rating Scale, CIRS), patient-informant discrepancy (Anosognosia Questionnaire Dementia, AQ-D), and performance discrepancy on different cognitive domains (self-appraisal discrepancies, SADs). Voxel-based morphometry correlational analyses were performed on magnetic resonance imaging (MRI) data with each anosognosia score. Increasing anosognosia on any anosognosia measurement (CIRS, AQ-D, SADs) was associated with increasing gray matter atrophy in the medial temporal lobe including the right hippocampus. Our results support a unitary mechanism of anosognosia in AD and MCI, in which medial temporal lobes play a key role, irrespectively of the assessment method used. This is in accordance with models suggesting that anosognosia in AD is primarily caused by a decline in mnemonic processes.

Abstract
Objective Current proxy measures for assessing everyday functioning (e.g., questionnaires, performance-based measures, and direct observation) show discrepancies in their rating of functional status. The present study investigated the relationship between multiple proxy measures of functional status and content memory (i.e., memory for information), temporal order memory, and prospective memory in an older adult sample. Method A total of 197 community-dwelling older adults who did (n = 45) or did not meet (n = 152) criteria for mild cognitive impairment (MCI), completed six different assessments of functional status (two questionnaires, two performance-based tasks, and two direct observation tasks) as well as experimental measures of content memory, prospective memory, and temporal order memory. Results After controlling for demographics and content memory, the temporal order and prospective memory measures explained a significant amount of variance in all proxy functional status measures. When all variables were entered into the regression analyses, content memory and prospective memory were found to be significant predictors of all measures of functional status, whereas temporal order memory was a significant predictor for the questionnaire and direct observation measures, but not performance-based measures. Conclusion The results suggest that direct observation and questionnaire measures may be able to capture components of everyday functioning that require context and temporal sequencing abilities, such as multi-tasking, that are not as well captured in many current laboratory performance-based measures of functional status. Future research should aim to inform the development and use of maximally effective and valid proxy measures of functional ability.

Abstract
OBJECTIVES Assessment of functional ability in people with early-stage dementia (PwD) is an important area of study because it forms part of the diagnostic process and may help in monitoring disease progression. Most researchers and clinicians rely on informant ratings rather than observing actual functional performance or employing self-ratings. There has however been little research to verify whether informant ratings of functioning are accurate, and there has been even less research investigating the accuracy of self-ratings of functional ability in PwD. No study has used the performance-monitoring metacognitive approach to investigate awareness of functional ability. METHODS Thirty-seven people with early-stage dementia completed an objective functional assessment and provided self-ratings before and after completing each section of the objective test. Informants provided ratings of functioning and burden. Scores were converted to percentages to allow for direct comparison. RESULTS Objectively assessed functional ability significantly correlated with self-ratings and informant ratings. Self-ratings did not correlate with informant ratings. For converted scores, self-ratings were more similar than informant ratings to the objectively assessed mean scores. Burden was unrelated to functional assessments after correcting for multiple comparisons. CONCLUSIONS Self-rated functional ability was more accurate than informant ratings when compared with objectively assessed ability, with informants tending to significantly underestimate the functional ability of PwD. The findings call into question the likelihood that informants will provide accurate ratings of functional ability and suggests that self-ratings may offer a more accurate estimate of functional ability. Self-ratings made by PwD should be more widely employed in clinical and research settings. Copyright © 2017 John Wiley & Sons, Ltd.

Abstract
The current review integrates recent findings regarding the construct of self-awareness in dementia from both clinical and cognitive perspectives. We present the predominant theoretical models of awareness and summarize both traditional and emerging approaches to assessing awareness from clinical and meta-cognitive perspectives. In this review, we focus primarily on findings from recent studies in anosognosia and meta-cognition in the context of neurodegenerative disease with special emphasis on Alzheimer's disease and frontotemporal dementia. Emerging trends in the study of awareness, including examination of the longitudinal course of anosognosia, and investigation of the neural substrates underlying meta-cognitive abilities are addressed. Finally, the practical importance of studying and assessing awareness from both theoretical and clinical angles is emphasized.

Abstract
BACKGROUND Minimal evidence exists on the detailed deficits in complex instrumental activities of daily living (IADLs) in mild dementia. The aim of this study was twofold, to validate a revised questionnaire focusing measuring the initiative and performance of IADLs in mild dementia and to explore the relationship between individual IADLs and patient and carer well-being. METHODS A total of 183 carers of people with mild dementia completed a further modified Revised Interview for Deterioration in Daily Living Activities 2 (R-IDDD2), which comprised new activities such as computer use, as well as sub-activities on the performance scale. Carers also completed questionnaires assessing patient quality of life (QoL-AD), carer quality of life (AC-QoL), and burden (GHQ-12). RESULTS Persons with dementia were significantly poorer initiating than performing cleaning, doing repair work, and preparing a hot or cold meal, whereas being poorer at performing dressing and following current affairs. Using the computer, preparing a hot meal, finance, and medication management were most impaired, whereas more basic activities of dressing, washing oneself, brushing hair or teeth, and preparing a hot drink were most preserved. Poor initiative and performance on nearly all activities were significantly related to reduced carer and patient well-being. CONCLUSIONS The R-IDDD2 offers a platform to comprehensively assess everyday functioning. Deteriorations in initiative and performance need to be targeted separately in interventions, as the former requires effective triggering and the latter structured training and support. Most activities were significantly associated with well-being, particularly patient quality of life so that improving any activity should improve well-being.

Abstract
Objective The autonomy of individuals is linked to the achievement of instrumental activities of daily living that require complex behavior. In the elderly, the assessment of autonomy is usually based on questionnaires that have strong subjective constraints. Considering this fact, we tested elderly healthy adults and Alzheimer disease patients using a new measure, the S-IADL (Simulation of Instrumental Activities for Daily Living), to assess the ability to perform effectively activities of daily living. Method The S-IADL shares many items with the well-known IADL questionnaire proposed by Lawton & Brody (1969). However, as opposed to the IADL, the assessment of autonomy is not based on the completion of a questionnaire but requires the realization or simulation of various activities of daily living. Eighty-three participants (69 healthy elderly, and 14 Alzheimer Disease patients) completed the IADL and performed the S-IADL assessment. Results Results revealed that, like the IADL, the S-IADL is able to identify AD patients who are likely to encounter difficulties in performing everyday activities, and no major differences were found between the IADL and the S-IADL. Conclusions We outlined some advantages for prefering, in certain situation, this new tool based on simulation of activities in functional evaluation. Finally, we discuss the main limits of the S-IADL that should be investigated prior to its utilization by clinicians.

Abstract
Informants serve an essential role in Alzheimer disease research. Were an informant to be replaced during a longitudinal study, this could have negative implications. We used data from the National Alzheimer's Coordinating Center Uniform Data Set to examine the frequency of informant replacement among Alzheimer disease dementia participants, whether patient and informant characteristics were associated with replacement, and how replacement affected research outcome measures. Informant replacement was common (15.5%) and typically occurred after the first or the second research visit. Adult child (24%) and other (38%) informants were more frequently replaced than spouse informants (10%). Older spouse informant age and younger adult child informant age were associated with replacement. The between-visit change in Functional Assessment Questionnaire scores was greater in patients who replaced informants than in those with stable informants. Clinical Dementia Rating-Sum of Boxes, Functional Assessment Questionnaire, and Neuropsychiatric Inventory scores showed greater variability in between-visit change in patients who replaced informants compared with those with stable informants. These findings suggest that informant replacement is relatively common, may have implications to study analyses, and warrant further examination in the setting of clinical trials.

Goal Setting for Cognitive Rehabilitation in Mild to Moderate Parkinson's Disease Dementia and Dementia with Lewy Bodies. PARKINSONS DISEASE 2016; 2016:8285041.

Abstract
Alongside the physical symptoms associated with Parkinson's disease dementia and dementia with Lewy bodies, health services must also address the cognitive impairments that accompany these conditions. There is growing interest in the use of nonpharmacological approaches to managing the consequences of cognitive disorder. Cognitive rehabilitation is a goal-orientated behavioural intervention which aims to enhance functional independence through the use of strategies specific to the individual's needs and abilities. Fundamental to this therapy is a person's capacity to set goals for rehabilitation. To date, no studies have assessed goal setting in early-stage Parkinson's disease dementia or dementia with Lewy bodies. Semistructured interviews were carried out with 29 participants from an ongoing trial of cognitive rehabilitation for people with these conditions. Here, we examined the goal statements provided by these participants using qualitative content analysis, exploring the types and nature of the goals set. Participants' goals reflected their motivations to learn new skills or improve performance in areas such as technology-use, self-management and orientation, medication management, and social and leisure activities. These results suggest that goal setting is achievable for these participants, provide insight into the everyday cognitive difficulties that they experience, and highlight possible domains as targets for intervention. The trial is registered with ISRCTN16584442 (DOI 10.1186/ISRCTN16584442 13/04/2015).

Abstract
OBJECTIVES In addition to neuropsychological difficulties, patients with cerebral small vessel disease (SVD) can have reduced activities of daily living and a poorer quality of life compared to healthy adults. The Brief Memory and Executive Test (BMET), is a cognitive screening tool designed to be sensitive to the neuropsychological profile of patients with SVD. While the BMET is sensitive to the cognitive consequences of SVD, it is unclear how well scores on this measure relate to functional outcomes. The aims of this study are to investigate the relationship between scores on the BMET and functional outcomes (activities of daily living and quality of life) in SVD, and to compare this with other commonly used cognitive screening tools. METHODS This study included 184 participants with SVD (mean age=63.2; SD=9.9) and 299 healthy controls (mean age=62.4; SD=13.8) who were tested using the BMET, Montreal Cognitive Assessment (MoCA), Mini-Mental State Examination (MMSE), Stroke Specific - Quality of Life Scale (SS-QoL), Geriatric Depression Scale (GDS), and measures of both instrumental activities of daily living (IADL) and basic activities of daily living (BADL). RESULTS After controlling for covariates the scores on the BMET, but not the MoCA or MMSE, were significantly related to poorer IADL and quality of life in the SVD group. In addition to the BMET scores, symptoms of depression were found to be significant associated with functional outcome. CONCLUSION These results support the clinical utility of using of the BMET, in combination with a standardized depression questionnaire, during the early assessment of patients with SVD.

Abstract
Research increasingly suggests that subjective cognitive decline (SCD) in older adults, in the absence of objective cognitive dysfunction or depression, may be a harbinger of non-normative cognitive decline and eventual progression to dementia. Little is known, however, about the key features of self-report measures currently used to assess SCD. The Subjective Cognitive Decline Initiative (SCD-I) Working Group is an international consortium established to develop a conceptual framework and research criteria for SCD (Jessen et al., 2014, Alzheimers Dement 10, 844-852). In the current study we systematically compared cognitive self-report items used by 19 SCD-I Working Group studies, representing 8 countries and 5 languages. We identified 34 self-report measures comprising 640 cognitive self-report items. There was little overlap among measures- approximately 75% of measures were used by only one study. Wide variation existed in response options and item content. Items pertaining to the memory domain predominated, accounting for about 60% of items surveyed, followed by executive function and attention, with 16% and 11% of the items, respectively. Items relating to memory for the names of people and the placement of common objects were represented on the greatest percentage of measures (56% each). Working group members reported that instrument selection decisions were often based on practical considerations beyond the study of SCD specifically, such as availability and brevity of measures. Results document the heterogeneity of approaches across studies to the emerging construct of SCD. We offer preliminary recommendations for instrument selection and future research directions including identifying items and measure formats associated with important clinical outcomes.

Abstract
SUMMARY The measurement of instrumental activities of daily living (IADL) is common in clinical practice and research into dementia. IADL are cognitively complex daily activities, such as cooking and doing finances. Their measurement is required for the diagnostic process of dementia, and also useful for the monitoring of disease progression. Since problems in IADL contribute to the disease burden of both patient and caregiver, it is a relevant outcome measure for disease-modifying and non-pharmacological interventions. Despite the widespread use of IADL instruments, an overview of its theoretical background, measurement methods, and potential sources of bias is lacking. In the current manuscript, we therefore aim to provide a selective overview of these topics.
