Table 2 Recommendations for test development

From: The need for harmonisation and innovation of neuropsychological assessment in neurodegenerative dementias in Europe: consensus document of the Joint Program for Neurodegenerative Diseases Working Group

Psychometric properties
Validity (i.e. does the task measure what it is intended to measure?) Content validity
Construct validity
Sensitivity and specificity (according to the examination issue)
Predictive validity
Cross-cultural validity (including multiple
language versions for verbal tests)
Clinical relevance
Definitions updating according to most recent neuroscientific evidence
Highly sensitive to early phases of dementia; differential diagnosis among dementias
Change monitoring over time
Minimal effects of literacy
Reliability Test/re-test stability; inter-rater reliability Avoid practice effects; parallel forms; avoid floor- and ceiling effects
Feasibility Balance between economic and human resources costs.
Availability of normative data across European countries
Optimise administration time; minimise discomfort to the patient
