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 Ins...

Instrumental activities of daily living (IADL) includes the integration of task-initiation, -planning, and -performance. Little is known on the cerebral perfusion correlates of these subcomponents of IADL in Alzheimer's disease (AD). In 121 AD patients, cerebral perfusion, using single-photon emission computed tomography, in 13 bilateral regions of interest (ROI) and the perfusion correlates of...

Introduction: Aging may increase physical or functional limitations, and India has a rapidly aging population. This study aimed to assess the prevalence and correlates of difficulties with Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) among older adults in India. Methods: The cross-sectional sample consisted of 31,477 individuals (≥ 60 years) from the Long...

Basic activities of daily living (ADL) are self-maintenance abilities such as dressing or bathing. Instrumental ADL (IADL) are more complex everyday tasks, such as preparing a meal or managing finances (Lawton & Brody, 1969). IADL questionnaires play an important role in assessing the functional abilities of older adults and evaluating the impact of cognitive impairment on routine activities. T...

INTRODUCTION Detecting functional decline from normal aging to dementia is relevant for diagnostic and prognostic purposes. Therefore, the Amsterdam IADL Questionnaire (A-IADL-Q) was developed: a 70-item proxy-based tool with good psychometric properties. We aimed to design a short version while preserving its psychometric quality. METHODS Study partners of subjects (n = 1355), ranging from c...

BACKGROUND It is unclear how well self-reports and clinician ratings of performance in the instrumental activities of daily living (IADLs; household maintenance tasks) correspond and why they may differ. METHODS We assessed clinician-rated IADL performance using an occupational therapy protocol, the Assessment of Motor and Process Skills (AMPS). AMPS and self-rated IADL disability were compar...

BACKGROUND As one ages, physical, cognitive, and clinical problems accumulate and the pattern of loss follows a distinct progression. The first areas requiring outside support are the Instrumental Activities of Daily Living and over time there is a need for support in performing the Activities of Daily Living. Two new functional hierarchies are presented, an IADL hierarchical capacity scale and...

BACKGROUND Maintaining independence in instrumental activities of daily living (IADL) is crucial for older adults. This study explored the association between cognitive and functional performance in general and in single IADL domains. Also, risk factors for developing IADL impairment were assessed. METHODS Here, 3,215 patients aged 75-98 years were included. Data were collected during home vi...

OBJECTIVE We aimed to evaluate the psychometric properties of the IADL measure included in the Dementia Care Assessment Packet (DCAP-IADL) in dementia patients. METHODS The study involved 112 dementia patients and 546 controls. The DCAP-IADL was scored in two ways: observed score (OS) and predicted score (PS). The reliability of the DCAP-IADL was evaluated by testing its internal consistency,...

Despite their limitations, mental status tests and self/proxy reports of instrumental activities of daily living (IADL) are often used to predict functional competence. In contrast, the Assessment of Motor and Process Skills (AMPS) is a direct observational assessment of IADL competence. Sixty-four community-dwelling elderly (20 Alzheimer's disease [AD] patients and 44 nondemented) were assesse...
