Inductive reasoning training has been found to be particularly effective at improving inductive reasoning, with some evidence of improved everyday functioning and driving. Telehealth may be useful for increasing access to, reducing time and travel burdens of, and reducing the need for physical spaces for cognitive training. On the other hand, telehealth increases technology burden. The present study investigated the feasibility and effectiveness of implementing an inductive reasoning training program, designed to mimic the inductive reasoning arm used in a large multi-site clinical trial (Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE)), via telehealth (using Zoom and Canvas as delivery platforms).

31 older adult participants (mean age = 71.2, range = 65-85; mean education = 15.5, range = 13-18; 64.5% female; 87.1% white) received 10-sessions of telehealth-delivered inductive reasoning training over 5 weeks. Comparison groups (inductive reasoning trained and no-contact controls) were culled from the in-person ACTIVE trial via propensity matching. All participants completed three pretest and posttest inductive reasoning measures (Word Series, Letter Series, Letter Sets), as well as a posttest measure assessing participant perceptions of the telehealth intervention. In addition, at the end of each of the ten training sessions, participants received a final inductive reasoning assessment.

Telehealth participants provided high levels of endorsement suggesting that the telehealth training program was useful, reliable, easy to use and interact on, and employed a useable interface. Participants were generally satisfied with the training program. With regard to performance, telehealth participants demonstrated greater gains than untrained controls on Letter Series [F(1, 116) = 9.81, p = 0.002, partial eta-squared = 0.084] and Letter Sets [F(1, 116) = 8.69, p = 0.004, partial eta-squared = 0.074], but did not differ in improvement on Word Series [F(1, 116) = 1.145, p = 0.287, partial eta-squared = 0.010]. Furthermore, telehealth participants evinced similar inductive reasoning gains as matched inperson inductive reasoning trained participants on Letter Series [F(1, 116) = 1.24, p = 0.226, partial eta-squared = 0.01] and Letter Sets [F(1, 116) = 1.29, p = 0.259, partial eta-squared = 0.01], but demonstrated fewer gains in Word Series performance [F(1, 116) = 25.681, p = < 0.001, partial eta-squared = 0.181]. On the end-of-session reasoning tests, telehealth-trained participants showed a similar general pattern of improvement across the ten training sessions and did not differ significantly from in-person trained comparison participants.

Cognitive training via telehealth evinced similar gains across nearly all measures as its in-person counterpart. However, telehealth also led to substantial challenges regarding the telehealth training platform. Despite these challenges, participants reported perceiving increased competence with computer use, peripherals (mice, trackpad), and videoconferencing. These may be ancillary benefits of such training and may be maximized if more age-friendly learning management systems are investigated. Overall, this study suggests that telehealth delivery may be a viable form of cognitive training in inductive reasoning, and future studies could increase performance gains by optimizing the online training platform for older adults.
