Remote testing in Abbiategrasso (RTA): results from a counterbalanced cross-over study on direct-to-home neuropsychology with older adults.

Background: The SARS-CoV-2 pandemic forced to rethink teleneuropsychology, since neuropsychological assessments started to be performed by phone or videoconference, with personal devices and without direct assistance from the clinician, a practice called "Direct-To-Home NeuroPsychology" (DTH-NP).

Aims: The present study, employing a counterbalanced cross-over design, was aimed at evaluating (1) the feasibility and (2) the acceptability of DTH-NP in Italian older adults without previously diagnosed neurocognitive disorder, (3) the comparability between remote and face-to-face administration of selected neuropsychological tests.

Methods: Fifty-eight community-dwelling older adults (65-85 years) were randomly assigned to one of two groups performing a complete neuropsychological assessment remotely (via phone call and videoconference) and face-to-face, in a counterbalance order, 8 weeks apart. The study recruitment rate was calculated, and the number of uncompleted tests and acceptability questionnaire responses were compared between the two administration modalities. Comparability was defined as good reliability of DTH-NP (intraclass correlation coefficient) and agreement between remote and face-to-face scores (Bland-Altman plots).

Results: Recruitment rate was 81%, with a preference for telephonic contact (79%). The acceptability analysis did not reveal any issues related to the DTH-NP assessment, even if most participants would rather repeat it face-to-face. Tests assessing short-term memory, language, and reasoning showed good comparability.

Discussion And Conclusion: Our results point out to a good recruitment rate in a DTH-NP study in an Italian population of older adults (mean age = 80), satisfying acceptability of DTH-NP and remote-face-to-face comparability of certain verbally mediated tests. Further studies including larger samples in videoconference modality, and outpatients, could better clarify its strengths and limits.
