Improving Patient Memory for Treatment for Mild Cognitive Impairment

Study Overview
=================
Brief Summary
-----------------
The main empirical question to be addressed is: What types of memory support are most potent for patients who are experiencing a mild cognitive impairment (MCI) relative to non-MCI patients?

Detailed Description
-----------------
People experiencing mild cognitive impairment (MCI) may benefit from adding memory support to treatment-as-usual. Adding memory support may be an innovative way to improve patient memory for treatment, adherence to treatment and outcome. The key question is: What types of memory support are most potent for MCI patients relative to non-MCI patients? The aim of the proposed research is to assess patient memory for treatment and the impact of adding memory support for people who are and are not experiencing MCI. The investigators will also compare the effectiveness of constructive vs. non-constructive memory supports for people who are experiencing MCI compared to people who are not experiencing MCI. Hypotheses: Recall of the content of treatment will be lower in the MCI group relative to the non-MCI group. Constructive memory support will be more effective for the non-MCI group relative to the MCI group. Non-constructive memory support will be more effective for the MCI group relative to the non-MCI group. The outcomes are: (1) patient memory for the content of treatment session and (2) the number and accuracy of thoughts and applications of the therapy points delivered. The investigators will also collect ratings of the acceptability of the treatment and the memory supports that are delivered. This dataset will also be used to better understand the sleep and circadian challenges that people with and without MCI report via the SCID for sleep disorders and the PROMIS scales.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Crossover Assignment
Interventional Model Description: Participants will be randomized to receive constructive memory supports in Session 1 OR to receive non-constructive memory supports in Session 1. In Session 2, participants will receive the type of memory support they did not receive in Session 1. In other words, if a participant received constructive memory support in Session 1, in Session 2 they will receive non-constructive memory support. And if a participant received non-constructive memory support in Session 1, in Session 2 they will receive constructive memory support. This cross-over design was adopted to increase the number of observations of the constructive and non-constructive memory support.
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Constructive memory support<br>Participants will watch videos of a sleep expert delivering treatment components from the Transdiagnostic Sleep and Circadian Intervention (TranS-C). After each video, a team member will deliver constructive memory supports. | Behavioral: Transdiagnostic sleep and circadian intervention (TranS-C)<br>* TranS-C is a psychosocial treatment that helps people who have sleep and circadian problems to improve their sleep health.<br>|
| Active Comparator: Non-constructive memory support<br>Participants will watch videos of a sleep expert delivering treatment components from the Transdiagnostic Sleep and Circadian Intervention (TranS-C). After each video, a team member will deliver non-constructive memory supports. | Behavioral: Transdiagnostic sleep and circadian intervention (TranS-C)<br>* TranS-C is a psychosocial treatment that helps people who have sleep and circadian problems to improve their sleep health.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of items recalled on the free recall task to assess outcome for constructive memory support | Assesses patient memory for treatment | Delivered two times: At the session in which constructive memory supports were used (baseline) and 1 week later. | 
| Number of items recalled on the free recall task to assess outcome for non-constructive memory support | Assesses patient memory for treatment | Delivered two times: At the end of the session in which non-constructive memory supports were used (baseline) and 1 week later. | 
| Number and accuracy of thoughts about the material covered in the prior treatment session in which constructive memory supports were delivered | To assess if the participant thought about the therapy session and if the thoughts accurately reflected the prior treatment session | Delivered once: At the beginning of the session held 1 week after the delivery of the constructive memory supports | 
| Number and accuracy of thoughts about the material covered in the prior treatment session in which non-constructive memory supports were delivered | To assess if the participant thought about the therapy session and if the thoughts accurately reflected the prior treatment session | Delivered once: At the beginning of the session held 1 week after the delivery of the non-constructive memory supports | 
| Number and accuracy of applications of the material covered in the prior treatment session in which constructive memory supports were delivered | To assess if the participant applied the material covered in the therapy session and if the participant accurately applied the material prior treatment session | Delivered once: At the beginning of the session held 1 week after the delivery of the constructive memory supports | 
| Number and accuracy of applications of the material covered in the prior treatment session in which non-constructive memory supports were delivered | To assess if the participant applied the material covered in the therapy session and if the participant accurately applied the material prior treatment session | Delivered once: At the beginning of the session held 1 week after the delivery of the non-constructive memory supports | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Acceptability of constructive memory support | Participants will be asked to rate the How acceptable were the memory supports we asked you through this session? The participant will then provide a rating from 1 Not at all acceptable to 9 Very acceptable. | One time point: At the end of the treatment session in which constructive memory support was delivered |
