About

This study will examine whether among older adults an adaptive and personalized reminder system can better support adherence to home-based cognitive training over typical reminder systems.

Full description

Many cognitive training interventions are associated with poor adherence, and poor adherence is associated with fewer benefits. Further, poor adherence in cognitive intervention studies can interfere with answering fundamental questions regarding intervention efficacy. This study will compare the effects of non-adaptive and smart adherence support systems. Participants will be asked to engage in frequent home-based cognitive training on a computer tablet. In the smart adherence support condition, participants will receive adaptive and tailored reminders based on dynamic algorithms that deploy reminders in a way that considers participant preferences, days and times of previous successful engagement, the success of previous reminder attempts, and answers to brief questions contained within reminder prompts. Parameter weights for these variables will be adjusted dynamically over a 6-month assessment period to ensure that reminders are deployed when they are most likely to be acted upon. This study will investigate adherence to training sessions, multiple times each week for 6 months, representing a large challenge to adherence. Participants will be randomly assigned to one condition or another, and adherence at home will be monitored. This will be an Individually Randomized Group-Treatment Trial (IRGT).

---

190 participants in 2 patient groups

Reminder Only Condition

Active Comparator group

Description:

To promote adherence, participants will receive generic reminders when home-based cognitive training has not been completed. This will be in the form of a text message to participants' smart phone.

Treatment:

Behavioral: Standard Reminder System (Active Control)

Smart Adherence Support Condition

Experimental group

Description:

To promote adherence, participants will receive reminders when home-based cognitive training has not been completed. This will be in the form of a text message to participants' smart phone. In this condition, participants will receive adaptive and tailored reminders based on dynamic algorithms that deploy reminders in a way that considers participant preferences, days and times of previous successful assessments, the success of previous reminder attempts, and answers to brief questions contained within reminder prompts. Parameter weights for these variables will be adjusted dynamically over a 6-month assessment period to ensure that reminders are deployed when they are most likely to be acted upon.
