简要总结
This Stage II randomized, controlled, longitudinal trial seeks to assess the acceptability, feasibility, and effects of a driving decision aid use among geriatric patients and providers. This multi-site trial will (1) test the driving decision aid (DDA) in improving decision making and quality (knowledge, decision conflict, values concordance and behavior intent); and (2) determine its effects on specific subpopulations of older drivers (stratified for cognitive function, decisional capacity, and attitudinally readiness for a mobility transition). The overarching hypotheses are that the DDA will help older adults make high-quality decisions, which will mitigate the negative psychosocial impacts of driving reduction, and that optimal DDA use will target certain populations and settings.
详细描述
The investigators will use a multi-site, two-armed randomized controlled trial of older drivers (n=300; ≥70 years) from clinical settings, and one family member each (n=up to 300), with longitudinal follow-up. Study goals are to test how much the DDA improves outcomes and identify who benefits most from the DDA. Evaluation of the DDA's efficacy (Aim 1) and its relative effect in subgroups (Aim 2) corresponds to Stage II in the NIH Stage Model for Behavioral Intervention Development. Findings from Aims 1 & 2 could identify necessary refinements (Stage I) and inform future efficacy, effectiveness or implementation trials.

结局指标
主要结局
Decisional Conflict Scale (DCS) Scores at Day 0 (Post-intervention)
时间窗: Day 0 (Post-intervention)
Decision conflict scale (DCS) is calculated from 16 items, with each item ranging from 0 (strongly agree) to 4 (strongly disagree). The total score is reported on a 0-100 scale by summing all responses, dividing by 16 and multiplying by 25. Higher scores represent greater levels of uncertainty in decision-making (higher decision conflict = worse outcome), and interventions often aim to reduce decision conflict (lower decision conflict = greater likelihood of implementing a decision = better outcome).
