Clinical Trial Summary

Mental illness is often chronic, severe, and difficult to treat. Though there has been significant progress towards establishing effective and efficient interventions for psychological health problems, many individuals do not gain lasting benefits from these treatments. The Memory Support Intervention (MSI) was developed utilizing existing findings from the cognitive science literature to improve treatment outcomes. In this study, the investigators aim to conduct an open trial that includes individuals 55 years and older to assess if a simplified version of the Memory Support Intervention improves sleep and circadian functioning, reduces functional impairment, and improves patient memory for treatment.

Description:

Given the huge burden associated with mental illness, a major challenge ahead is to hasten progress toward developing and testing highly efficient and effective interventions for psychological health problems. Progress toward establishing evidence-based psychosocial treatments for most types of mental illness has been excellent, particularly the cognitive and behavioral treatments (CBT). However, much work remains. The effect sizes are moderate, gains may not persist, and there are patients who derive little or no benefit. Even under optimal conditions, treatment failure is too common. Hence, the challenge is to improve outcomes. Seminal progress toward meeting this challenge must include innovations that are safe, powerful, inexpensive and simple (for fast and effective dissemination).

The proposed research seeks to extend the investigators' program of research on one such innovation. With an R34 and an R01 from NIMH, the investigators have been seeking to improve outcome by improving memory for the content of therapy sessions. To achieve this goal, the investigators have developed and adapted existing findings from the education and cognitive science literatures. The resulting Memory Support Intervention (MSI) involves a series of specific procedures that support the encoding and retrieval stages of an episodic memory.

This line of research arises from several lines of evidence: (a) memory for the content of therapy sessions is poor and (b) memory impairment is modifiable. Although the outcomes will be relevant to psychosocial treatments for a broad range of problems, the focus of this proposal is one treatment for sleep and circadian dysfunction because (a) sleep problems are one of the most prevalent psychological health problems, (b) there is substantial and promising evidence for the efficacy of the transdiagnostic sleep and circadian (TranS-C), yet there is also room for improvement in outcome and (c) sleep problems are associated with memory impairment.

This pilot study will be conducted in order to collect data on individuals who are 55 years and older because memory functioning can decline over this phase of the lifespan. Sleep and circadian problems are also common.

The aim is: To conduct an open trial that includes n = 40 individuals 55 years and older to assess if the Memory Support Intervention (a) improves sleep and circadian functioning, (b) reduces functional impairment and (c) improves patient memory for treatment.

• Chronobiology Disorders
• Circadian Dysregulation
• Sleep Disorder
• Sleep Wake Disorders

Intervention

Behavioral:
• Trans-C for sleep and circadian function + Memory Support
The Memory Support Intervention will be delivered interwoven with Trans-C. The Memory Support Intervention is designed to improve patient memory for treatment and involves a series of specific procedures that support the encoding and retrieval stages of episodic memory. The memory support strategies are proactively, strategically and intensively integrated into treatment-as-usual to support encoding. Memory support is delivered alongside each 'treatment point', defined as a main idea, principle, or experience that the treatment provider wants the patient to remember or implement as part of the treatment.

Primary	Sheehan Disability Scale	Assesses functional impairment on a scale from 0 to 30, where higher scores mean higher impairment	Change from baseline to post-treatment, which is 8-10 weeks after the beginning of treatment
Secondary	Positive and Negative Affect Scale	Positive affect scores can range from 10-15, with higher scores representing higher levels of positive affect. Negative affect scores can range from 10-50, with lower scores representing lower levels of negative affect	Change from baseline to post-treatment, which is 8-10 weeks after the beginning of treatment
