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: 1. Recall of the content of treatment will be lower in the MCI group relative to the non-MCI group. 2. Constructive memory support will be more effective for the non-MCI group relative to the MCI group. 3. 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.
Interventions
BEHAVIORALTransdiagnostic sleep and circadian intervention (TranS-C)
TranS-C is a psychosocial treatment that helps people who have sleep and circadian problems to improve their sleep health.

SINGLE (Subject)
Masking description
Participants will not be aware that they are receiving constructive memory support in one session and non-constructive memory support in the next session
Intervention 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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number and accuracy of thoughts about the material covered in the prior treatment session in which constructive memory supports were delivered | Delivered once: At the beginning of the session held 1 week after the delivery of the constructive memory supports | To assess if the participant thought about the therapy session and if the thoughts accurately reflected the prior treatment session |
| Number of items recalled on the free recall task to assess outcome for constructive memory support | Delivered two times: At the session in which constructive memory supports were used (baseline) and 1 week later. | Assesses patient memory for treatment |
| Number of items recalled on the free recall task to assess outcome for non-constructive memory support | Delivered two times: At the end of the session in which non-constructive memory supports were used (baseline) and 1 week later. | Assesses patient memory for treatment |
| Number and accuracy of applications of the material covered in the prior treatment session in which non-constructive memory supports were delivered | Delivered once: At the beginning of the session held 1 week after the delivery of the non-constructive memory supports | To assess if the participant applied the material covered in the therapy session and if the participant accurately applied the material prior treatment session |
| Number and accuracy of thoughts about the material covered in the prior treatment session in which non-constructive memory supports were delivered | Delivered once: At the beginning of the session held 1 week after the delivery of the non-constructive memory supports | To assess if the participant thought about the therapy session and if the thoughts accurately reflected the prior treatment session |
| Number and accuracy of applications of the material covered in the prior treatment session in which constructive memory supports were delivered | Delivered once: At the beginning of the session held 1 week after the delivery of the constructive memory supports | To assess if the participant applied the material covered in the therapy session and if the participant accurately applied the material prior treatment session |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Acceptability of constructive memory support | One time point: At the end of the treatment session in which constructive memory support was delivered | 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. |
Other
| Measure | Time frame | Description |
|---|---|---|
| PROMIS-Sleep Disturbance | At baseline | Assesses perceived functional impairments related to sleep problems using a self-report questionnaire. The minimum value is 8. The maximum value is 40. Higher scores mean more sleep disturbance (worse outcome). |
| Signs of patient understanding the memory support items | Two time points: During the treatment session that constructive memory support was delivered and during the treatment session that non-constructive memory support was delivered | Coded from video tapes of the two treatment sessions in which the support was delivered |
| PROMIS-Sleep-related impairment | At baseline | Assesses perceived functional impairments related to sleep problems in a self-report questionnaire. The minimum value is 16. The maximum value is 80. Higher scores mean more sleep related problems (worse outcome). |
| British Columbia Cognitive Complaints Inventory | At baseline | Assessed perceived cognitive difficulties, scale consists of 6 items. Scores can range from 0-18 with higher scores indicating higher levels of perceived cognitive difficulties |
| Cognitive Failures Questionnaire | At baseline | Used to assess the frequency with which people experienced cognitive failures. Scores range from 0-100, with higher scores indicating higher levels of cognitive failures. |
| Montreal Cognitive Assessment | At baseline | An assessment of cognitive functioning |
| Structured Clinical Interview for Sleep Disorders - revised | At baseline | An assessment of the sleep and circadian problems experienced by the participant |
| Learning behavior exhibited by the patient | Two time points: During the treatment session that constructive memory support was delivered and during the treatment session that non-constructive memory support was delivered | Coded from video tapes of the two treatment sessions in which the support was delivered |
