AbstractBackgroundFunctional impairment is a diagnostic criterion for dementia and distinguishes mild cognitive impairment (MCI) from dementia. Self‐ or informant reports are most commonly used but can be biased and may not reflect actual functional ability. Alternatives include performance‐based assessments, such as the Sydney Test of Activities of daily living in Memory disorders (STAM). The aim of this study is to develop, and validate, a new computerised diagnostic tool (C‐STAM) to assess functional ability that can be administered remotely to increase accessibility. The C‐STAM will realistically simulate everyday activities to assess functional performance.MethodThe C‐STAM is being developed by a multidisciplinary team of psychologists, old age psychiatrists, occupational therapists, and computer scientists. A Delphi study with 31 international experts was conducted to select and refine suitable tasks. An additional step is consultation with consumers (i.e., older people with and without cognitive impairment) and caregivers who have an active role in shaping the C‐STAM. A pilot study with 30 people aged 60+ with normal cognition, MCI, and dementia plus their informants will assess feasibility and user‐experience. After adjustments based on the pilot study, we will conduct a validation study with 180 participants and their informants.ResultThe Delphi study resulted in nine C‐STAM tasks, addressing the domains of communication, shopping, dressing, community mobility, handling finances, managing medications, and memory. Feasibility and acceptability of these tasks will be confirmed through pilot testing and the validation study. We will develop an automated scoring and interpretation guide, age‐ and sex‐specific norms, and clinical cut‐offs to differentiate the three diagnostic groups. Automated data exporting and reporting will be useful for clinical referrals and in research and will facilitate interpretation and communication of results across different clinical settings.ConclusionThe C‐STAM will facilitate early diagnosis of dementia and MCI and will enable a better understanding of disease progression by monitoring functional ability in a time‐ and resource‐efficient way. Results will be used to inform service development to better meet the needs of people with dementia for access to appropriate assessments of functional performance. The C‐STAM will be freely available for use by clinicians and in research.
