Registered outcomes3
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Association between features of human-AI chatbot conversations and cognitive screening score | Day 1 (single online session at enrollment, about 20-30 minutes) | The study measures linguistic and interactional features from participants' uploaded AI chatbot conversations and from two standardized chatbot tasks. Examples include request specificity and structure, context maintenance, repetition, clarification, error recognition, revision strategies, task progression, and typing and timing patterns. The association between these features and the MoCA XpressO total score is analyzed, with the score treated as a continuous measure. |
| Secondary | Patterns of AI chatbot use | Day 1 (single online session at enrollment) | Descriptive summary of self-reported AI chatbot use: platforms used, duration and frequency of use, main purposes, language of use, and whether others help with use. Collected by questionnaire. |
| Secondary | Performance of conversation features in estimating cognitive screening score | Day 1 (single online session at enrollment) | How well computational models based on conversation features estimate the MoCA XpressO score, assessed with cross-validation. Reported as correlation with the observed score and as the area under the ROC curve for classifying scores above versus below the validated cutoff. |
