Intervention Comparative Effectiveness for Adult Cognitive Training

Percent confidence that a given vignette describing fraud is actually an example of fraud, measured at baseline and immediately after 4 weeks of training. Participants were given a vignette describing fraud (which was mixed in with vignettes not describing fraud) and were asked to give their percent confidence that this is actually an example of fraud. Higher confidence indicates higher accuracy when detecting fraud, with a minimum of 0 and a maximum of 100. Measures accuracy in discriminating fraud from non-fraud text-based scenarios (using 3 parallel forms).

Driving simulator (scenarios including hazards) measures of speed, maximum brake compression, and lane position, at baseline and immediately after 4 weeks of training. These measures provide an estimate of accuracy in driving scenarios that involve hazards in the DriveSafety simulator (using 3 parallel forms). All measures were transformed into Z scores and averaged in order to create a measure of overall driving performance, where higher scores represent more dangerous (worse) driving performance.

Self-reported difficulties in completing instrumental activities of daily living, measured at baseline and immediately after 4 weeks of training, with a minimum score of 0 (indicating no difficulty) and a maximum of 3 (indicating severe difficulty). This is a modified short-form version of the Lawton IADL Items, used in the Multicenter AIDS Cohort Study (MACS).

Percent confidence that a given vignette describing fraud is actually an example of fraud, measured at baseline and one year after 4 weeks of training. Participants were given a vignette describing fraud (which was mixed in with vignettes not describing fraud) and were asked to give their percent confidence that this is actually an example of fraud. Higher confidence indicates higher accuracy when detecting fraud, with a minimum of 0 and a maximum of 100. Measures accuracy in discriminating fraud from non-fraud text-based scenarios (using 3 parallel forms).

Driving simulator (scenarios including hazards) measures of speed, maximum brake compression, and lane position, at baseline and one year after 4 weeks of training.

Test questions based on the American Association of Retired Persons driving course, measured one year after 4 weeks of training, with a minimum score of 0 and a maximum score of 3. Higher scores indicate more accurate knowledge of driving related information.

Test questions based on the Finance and Fraud training tutorial, measured immediately after one year of training, with a minimum score of 0 and a maximum score of 3. Higher scores indicate more accurate knowledge of finance and fraud related information.

Average speed in a driving simulator measured at baseline and immediately after 4 weeks of training. Speed is a continuous measure in miles per hour, with a minimum of 0 and no maximum. Speed may indicate risky driving behavior.

Maximum brake compression in a driving simulator measured at baseline and immediately after 4 weeks of training. Maximum brake compression measures the most that the brake pedal was compressed during driving, with a minimum of 0 and a maximum of 1. Maximum brake compression may indicate urgent stopping.

Average lane position in a driving simulator measured at baseline and immediately after 4 weeks of training. Lane position measures the average deviation from the center of a lane while driving (values from -1 to 1), averaged across participants, where 0 represents perfect center, negative scores represent deviation to the left (from 0 to -1), and positive scores represent deviation to the right (from 0 to 1). Lane position indicates vehicle control and safety.

Average speed in a driving simulator measured at baseline and one year after 4 weeks of training. Speed is a continuous measure in miles per hour, with a minimum of 0 and no maximum. Speed may indicate risky driving behavior.

Maximum brake compression in a driving simulator measured at baseline and one year after 4 weeks of training. Maximum brake compression measures the most that the brake pedal was compressed during driving, with a minimum of 0 and a maximum of 1. Maximum brake compression may indicate urgent stopping.

Average lane position in a driving simulator measured at baseline and one year after 4 weeks of training. Lane position measures the average deviation from the center of a lane while driving (values from -1 to 1), averaged across participants, where 0 represents perfect center, negative scores represent deviation to the left (from 0 to -1), and positive scores represent deviation to the right (from 0 to 1). Lane position indicates vehicle control and safety.

Useful field of view (UFOV) measured at baseline and immediately after 4 weeks of training. UFOV is measured as a response time in milliseconds, with lower times indicating quicker responses.

The Digit Symbol Substitution Test measured at baseline and immediately after 4 weeks of training. The Digit Symbol Substitution Test is measured through the number of items completed during a 90 second period, where higher scores indicate faster/better performance.

Standardized Z-scores of Computer Proficiency Questionnaire and the Mobile Device Proficiency Questionnaire, at baseline and immediately after 4 weeks of training, which provide measures of technology proficiency. Scores are measured as a self-assessed proficiency, where higher scores indicate a higher proficiency and greater ease using a device on various tasks. Scores are standardized using z-scores, with the average at the baseline representing 0, and 1 representing one standard deviation above the average baseline score.
