抽象

The investigators will conduct a randomized controlled trial (RCT), comparing SSM (n=96) versus HEP (n=96) in 192 LLD participants stratified by site and presence of treatment resistant late life depression (TR-LLD). Participants will be blinded to the treatment hypothesis while investigators, raters and treating clinicians will be additionally blinded to the intervention. Both SSM and HEP will be taught over 4 consecutive days in similar sized groups (4-10 participants) followed by weekly reinforcement sessions for subsequent 11 weeks. Trained raters will collect data on depression symptoms (HAM-D 17 scale) and cognition at baseline, 12-week and 26-week follow-up as the primary and secondary outcome measures respectively.

描述

RECRUITMENT AND CONSENT:

Participants will either be recruited from primary-, secondary-, and tertiary-care centres or from self-referral (general public). Montreal patients will be recruited from the Douglas Institute and associated Integrated University Health and Social Services Centres (CIUSSS)-Ouest de l'ile Local Community Services Centres (CLSCs) (CLSC Verdun and CLSC Lasalle), Jewish General Hospital (JGH) Psychiatry clinics (Institute for Community and Family Psychiatry) and associated CIUSSS-Centre-Ouest family medicine clinics/CLSCs: CLSC Benny Farm, CLSC Rene Cassin, CLSC Côte Des Neiges, CLSC Metro, CLSC Parc Extension, Herzl Family Medicine JGH, St-Mary's Dept. of Psychiatry, and McGill University Health Centre (MUHC) Dept. of Psychiatry. London participants will be recruited from London Health Science Centre (LHSC) sites (Victoria Hospital and University Hospital) and Parkwood Institute - Mental Health Care Building. Participants will be screened for eligibility and given a letter of information (LOI) for their review. After 24 hours, a research assistant will contact the participant and, if they are interested in participating and eligible to participate in the research study, they will be recruited into the study after valid consent is received.

STUDY INTERVENTION:

This study is a 12-week, randomized controlled trial seeking to recruit 192 participants with late-life depression total across two sites - (1) McGill University, Montreal, Quebec (QC), and (2) University of Western Ontario in London, Ontario (ON). Participants will be randomly assigned to one of two conditions: Sahaj Samadhi Meditation (SSM) or the Health Enhancement Program (HEP). The SSM intervention will be offered by trained and certified teachers from the Art of Living Foundation at Montreal and London between August 2018 and August 2021. The HEP intervention will be offered by a trained Nurse Practitioner, Social Worker, Psychologist, Occupational Therapist or other qualified professional at Montreal and London between August 2018 and August 2021. Raters, clinicians, and care providers will be blind to participant study condition.

SSM (the experimental group) and HEP (the active control group) require participants to attend training for 4 days, attend weekly follow-up sessions, and to practice the trained techniques at home for 20-minutes per day (details of each intervention can be found below). Participants will additionally be asked to fill out "homework logs" to record days they practiced the trained technique. A total of 3 assessment sessions are planned for participants to attend: to occur at baseline (0-week) as well as at 12-week and 26-week follow-ups.

MENTAL HEALTH ASSESSMENTS:

Participants will be screened using the Screening for Cognitive Impairment in Older Adults (Mini-Cog), Patient Health Questionnaire (PHQ-9), the Magnetic Resonance Imaging (MRI) pre-screening questionnaire, the Mini International Neuropsychiatric Interview, and the Antidepressant Treatment History Form (ATHF). Participants will be tested for the primary outcome, depression, using the Hamilton Depression Rating Scale (HAM-D17). The secondary outcome, executive functioning, will be measured by the Delis-Kaplan Executive Function System (D-KEFS), Rey-Osterrieth Complex Figure-Copy Trial, and the California Verbal Learning Test-II-Short Form. Measures of primary and secondary outcomes will be administered at all 3 assessment sessions. All measures are described below.

BLOOD DRAW:

Blood draws will be performed at baseline (0-weeks) and 12-week follow-up by a qualified nurse at the CLSC in Montreal and Parkwood Mental Health in London. The blood collected will be stored at the Douglas Mental Health University Institute in Montreal, QC, and at Robart's Research Institute in London, ON.

GAIT:

Gait data will be collected in London, Ontario, only. The data to be collected is weight, height, waist circumference, and hip circumference. Gait data will be measured alongside the Falls Efficacy Scale (FES-I) (described below).

MRI:

The investigators aim to recruit a total of 50 participants (25 from each group) from the SSM/HEP study into a magnetic resonance imaging (MRI) study that will involve MRI scans at baseline and at the 12-week follow-up. Participants eligible for this sub-study will have had to complete the MRI pre-screening questionnaire. Those who are part of this sub-study will be invited to attend two MRI scanning sessions, which are expected to take about 1.5 h, to occur at baseline and the 12-week follow-up. Each MRI appointment will be completed in addition to the tasks described above.

主要结果指标

1. Change in depressive symptoms: Hamilton Depression Scale (HAM-D17) [Change from week 0 to week 12 and change from week 0 to week 26.]

The HAM-D17 is a measure of depressive symptoms. Higher scores on this scale indicate greater depression severity; whereas lower scores indicate minimal/no presence of depression. Change in participant scores on this scale throughout the study will be assessed.

次要成果指标

1. Delis-Kaplan Executive Function System (D-KEFS): Verbal Fluency Test [0 weeks (baseline); 12 weeks; and 26 weeks]

The Verbal Fluency Test of the D-KEFS asks participants to provide responses according to rules set out by 3 sub-tests (letter fluency, category fluency, and category switching). Correct and incorrect responses are scored. The higher number of correct responses and the lower number of incorrect responses is indicative of stronger verbal fluency. A higher number of incorrect responses and/or lower number of correct responses in one of the sub-tests may indicate neurological dysfunction in a corresponding brain region. No global score is generated.

2. California Verbal Learning Test-II (CVLT-II), Short Form [0 weeks (baseline); 12 weeks; and 26 weeks]

The CVLT-II is a tool used to assess verbal learning and memory. Scores are determined by recording correct and incorrect responses on each task. Raw scores are used to assess overall performance on the CVLT-II, with higher correct responses and lower incorrect responses indicating good executive functioning.

3. Rey-Osterrieth Complex Figure-Copy Trial [0 weeks (baseline); 12 weeks; and 26 weeks]

This neuropsychological test asks participants to draw an image they have been shown after no delay (copying it), a short delay, and a longer delay. The accuracy of each drawn image to the original at each time point is indicative of neurological systems' functioning level.

其他成果措施

1. Generalized Anxiety Disorder 7-item (GAD-7) scale [0 weeks (at screening or at baseline); 12 weeks; and 26 weeks]

A measure of anxiety with 7 items scored from 0-3. Higher scores indicate greater depressive symptoms (5-9, mild anxiety; 10-14, moderate anxiety; 15-21 severe anxiety).

2. Clinical Global Impression (CGI) scale [0 weeks (baseline); 12 weeks; and 26 weeks]

The CGI is a 3-item scale, psychiatric tool meant to provide an overall picture of a participant's illness severity (1-normal to 7-amongst the most severely ill patients), improvement/change (1-very much improved to 7-very much worse), and therapeutic response (0-marked improvement with no side-effects to 4-unchanged or worse and side-effects outweigh the therapeutic effects). No global score is generated.

3. Athens Insomnia Scale [0 weeks (baseline); 12 weeks; and 26 weeks]

The Athens Insomnia Scale is a measure of sleep difficulties with each item representing a different aspect of sleep (e.g. "Overall Quality of Sleep"). Ratings are from 0 to 4, with 0 being no difficulty with the item and 4 being the most difficulty with the item. Higher overall scores on this scale indicate higher difficulties with sleep.

Participants provide responses from 1 to 5, with 1 being "None" and 5 being "Extreme or cannot do". Item raw scores, raw domain scores, and domain average scores (out of 5) are generated as well as a "General Disability Score (Total)" and a global average score (out of 5). Higher scores indicate greater difficulty with the item, the domain, overall, or on average.

5. Euroqol 5 Dimension 5 Level (EQ-5D-5L) [0 weeks (baseline); 12 weeks; and 26 weeks]

The EQ-5D-5L is a 2 page assessment of a participant's self-rated health state on that day. The first page asks participants to indicate how much difficulty they have in a health dimension (e.g. "Mobility") using one of 5 levels: no problems, slight problems, moderate problems, severe problems, or extreme problems. Higher scores indicate greater severity of problems with a health dimension or overall. The second page asks participants to rate their current health state on a scale from 0 ("the worst health you can imagine") to 100 ("the best health you can imagine"). This section serves as a subjective measure of a participant's own health.

6. Toronto Side Effects Scale (TSES) [0 weeks (baseline); 12 weeks; and 26 weeks]

This 32-item scale asks about a broad variety of participant reported side effects. The scale assesses the frequency and intensity of side effects on a 5-point Likert scale, with higher scores indicating greater frequency/severity of the side effect.

7. Montreal Cognitive Assessment (MoCA; London only) [0 weeks (baseline); 12 weeks; and 26 weeks]

11. Phenomenology of Consciousness Inventory (PCI) [12 weeks; and 26 weeks]

The PCI is a self-report measure containing 53 items about an immediately preceding subjective experience, scored on 7-point scales between opposing statements. The items are organized into 21 scales that include altered states of awareness, self-awareness, altered experiences, volitional control, rationality, internal dialogue, positive affect (which includes joy, love and sexual excitement), negative affect (which includes anger, sadness and fear), imagery, attention, memory and arousal. Scores on the scales will be used to assess the degree to which a person has experienced an altered state of consciousness.

12. Ryff Scales of Psychological Well-Being (SPWB) [0 weeks (baseline); 12 weeks; and 26 weeks]

SPWB is a self-report measure with 54 short questions that creates scores for six dimensions of psychological well-being: self-acceptance, the establishment of quality ties to others, a sense of autonomy, the pursuit of meaningful goals and a sense of purpose in life, and continued growth and development as a person. This measure is scored on a 6-point scale from "Strongly Disagree" to "Strongly Agree." These scales are regarded as separate dimensions of psychological well-being but can also be aggregated for a global score.
