Registered outcomes 6
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | Completion rate of cognitive test set (feasibility) | Measured once, as this is a cross-sectional study (time to complete cognitive tests is estimated to be 1.5 hours) | Proportion of registered participants who complete all the cognitive testing. | ClinicalTrials.gov |
| Secondary | Reliability of web-based vs in-person working memory testing (n-back test) | Web-based and in-person testing will occur at two separate time points, at least 1 month apart and no more than 3 months apart | Intraclass correlation coefficient for web-based vs. in-person performance on the n-back test will be computed | ClinicalTrials.gov |
| Secondary | Reliability of web-based vs in-person executive function testing (Stroop test performance) | Web-based and in-person testing will occur at two separate time points, at least 1 month apart and no more than 3 months apart | Intraclass correlation coefficient for web-based vs. in-person performance on the Stroop test will be computed | ClinicalTrials.gov |
| Secondary | Reliability of web-based vs in-person visuospatial function testing (Trail making test performance) | Web-based and in-person testing will occur at two separate time points, at least 1 month apart and no more than 3 months apart | Intraclass correlation coefficient for web-based vs. in-person performance on the Trail making test will be computed | ClinicalTrials.gov |
| Secondary | Reliability of web-based vs in-person declarative memory testing (recognition memory) | Web-based and in-person testing will occur at two separate time points, at least 1 month apart and no more than 3 months apart | Intraclass correlation coefficient for web-based vs. in-person performance on the image recognition test will be computed | ClinicalTrials.gov |
| Secondary | Reliability of web-based vs in-person reward processing testing | Web-based and in-person testing will occur at two separate time points, at least 1 month apart and no more than 3 months apart | Intraclass correlation coefficient for web-based vs. in-person performance on the probabilistic reward task will be computed | ClinicalTrials.gov |
