Cognitive Stimulation Therapy for Dementia: A Two-Armed Pragmatic Trial
Study Details
Study Description
Brief Summary
Cognitive Stimulation Therapy (CST) is an evidence-based non-pharmacological group therapy shown to benefit people with mild to moderate dementia. Despite increasing availability of CST worldwide, access remains limited in the United States. This pilot pragmatic trial will embed CST referral into the standard care protocol of health care settings that serve people living with dementia in the state of Connecticut, and evaluate online delivery of CST known as virtual CST (V-CST), and assess the acceptability of V-CST to people living with dementia.
The study design is a two-armed randomized embedded pragmatic clinical trial (ePCT). The trial aims to determine if cognitive decline is experienced less commonly among V-CST participants than control group members based on three widely used measures of cognition, the Montreal Cognitive Assessment (MoCA), St. Louis University Memory Screen (SLUMS), and Mini Mental State Exam (MMSE).
The study population will be persons with mild to moderate dementia identified by clinicians in standard care. From this population, subject participants will be randomized to intervention and control groups. Patients randomly assigned to the intervention group will be referred by their clinical providers to participate in V-CST, and those who accept the referral will participate in the intervention.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: Referral for Cognitive Stimulation Therapy This group will receive a referral from their physician for CST treatment |
Behavioral: Referral for Cognitive Stimulation Therapy
Physician will review participant eligibility for CST treatment and offer referral based on clinical judgement
|
| Placebo Comparator: Standard of Care This group will receive standard of care and no CST referral. |
Other: No change to Standard of Care
Participants will not receive referral from a physician. They will continue with standard of care at their site.

Outcome Measures
Primary Outcome Measures
- Cognitive decline measured by an increase in Montreal Cognitive Assessment Score from baseline to follow-up [6 months]
Clinically meaningful cognitive decline will be less common in intervention group than the control group. Clinically meaningful changes will be assessed using one of the following cognitive assessment tools: Montreal Cognitive Assessment (MoCA), Saint Louis University Mental Status (SLUMS) exam, or the Mini-Mental State Examination (MMSE). A 'crosswalk' will be used to convert all cognitive assessment measures to a MoCA score. All participants will start with a baseline MoCA score of 10 to 26 which indicates mild-moderate cognitive impairment. An increase in the baseline MoCA score by 2 points or greater indicates a clinically meaningful decline in cognitive status. Cognitive assessments will be collected at baseline and 6 months follow-up visit after baseline/enrollment. All cognitive assessments will be done by the study physicians. The cognitive assessment collected at baseline will be the cognitive assessment used to assess cognitive impairment at the 6 month follow-up.
Secondary Outcome Measures
- Cognitive improvement measured by a decrease in Montreal Cognitive Assessment Score from baseline to follow-up [6 months]
Clinically meaningful cognitive improvement will be more common in the intervention group than the control group. Clinically meaningful changes will be assessed using one of the following cognitive assessment tools: Montreal Cognitive Assessment (MoCA), Saint Louis University Mental Status (SLUMS) exam, or the Mini-Mental State Examination (MMSE). A 'crosswalk' will be used to convert all cognitive assessment measures to a MoCA score. All participants will start with a baseline MoCA score of 10 to 26 which indicates mild-moderate cognitive impairment. A decrease in the baseline MoCA score by 2 points or greater indicates a clinically meaningful improvement in cognitive status. Cognitive assessments will be collected at baseline and 6 months follow-up visit after baseline/enrollment. All cognitive assessments will be done by the study physicians. The cognitive assessment collected at baseline will be the cognitive assessment used to assess cognitive impairment at the 6 month follow-up.
- Referral Acceptance Rate [1 month]
V-CST referral will be favorably received by participants. V-CST referral will be assessed by referral acceptance rate measured by percentage of people referred for V-CST who accept the referral over the 1-month referral period process. This outcome will be assessed at the end of the referral process.
- Participant attendance [7 weeks]
V-CST treatment will be favorably received by participants. Participant attendance will be measured as the percentage of enrolled participants who attend each V-CST session. V-CST sessions will be conducted over a 7-week period. This outcome will be assessed at the end of the 7th week V-CST session.
- Participant Attrition [7 weeks]
V-CST treatment will be favorably received by participants. Participant attrition will be measured as the percentage of enrolled participants who cease attending V-CST between session 1 and session 14. V-CST sessions will be conducted over a 7-week period. This outcome will be assessed at the end of the 7th week V-CST session.
