About
The purpose of this study is to examine the effectiveness of a specific, protocol-based group music therapy intervention, relative to a verbal discussion activity. The study will examine the impact of the specified music therapy intervention on: (1) affective outcomes, (2) social engagement behaviors, and (3) observed quality of life of persons with ADRD. This study will use a within-subjects randomized crossover design involving N=30 persons with ADRD from nursing homes to examine two levels of independent variable: singing-based music therapy and verbal discussion. Both conditions will be held in small groups of 3-6 participants. Nursing homes will be randomly assigned to an intervention sequence in a counterbalanced order (either music therapy first or verbal discussion first), and participants serve as their own controls. Each condition will occur three times per week for two consecutive weeks (6 sessions per treatment). Each session lasts for 25 minutes in the afternoon. A 2-week "wash-out" period (i.e., usual treatment) will occur between conditions. Participants will remain with their assigned small group for all study activities (i.e., music therapy, verbal discussion). Board-certified music therapists (i.e., MT-BC) will lead both conditions and will complete systematic training to ensure these conditions are implemented as intended, following a manualized protocol. An independent auditor will conduct random checks to ensure the music therapists are implementing the conditions as stipulated in the protocol. Data takers will complete systematic, manualized training to ensure reliable data collection.
Full description
-
Following the consent process, the PI will collect demographics, music background, and preference information from participants' family and/or facility care staff. Where possible, the PI will ask participants directly about their music preferences.
-
The main study period will last 9 weeks and will consist of the following: (a) a "pre-study" week involving a practice session that includes aspects of both study conditions. All study personnel, and facility staff, will gain practice running through study procedures; (1) one week of usual treatment (UT) to collect baseline mood and quality of life data; (2-3) random assignment to two weeks of either music therapy or the verbal discussion; (4-5) a two-week washout period for collecting mood and quality of life data during return to UT; (6-7) crossover to the other condition; and (8) one final week return to UT with mood and quality of life data collection.
-
The PI will collect descriptive information during the pre-study week and first week of UT using the following measures (previously validated with this population):
- Clinical Dementia Rating (CDR; Morris, 1993), consists of semi-structured interviews with the patient and an informant by a trained rater (in this case, the PI) regarding memory, orientation, judgment and problem solving, community affairs, hobbies, and personal care. Provides information depth. Scores range from 0 ("normal") to 3 (severe dementia).
- Montreal Cognitive Assessment (MoCA; Nasreddine et al., 2005), a brief screening of cognitive function. Scores range from 0 (greatly impaired) to 30 (unimpaired). Provides a quick assessment of cognitive functioning.
- Charlson Age-Comorbidity Index (CACI; Charlson et al., 1987), compares the severity of International Classification of Diseases diagnosis codes and provides a systematic way to quantify general health in clinical research, via chart review. Scores range from 0 (excellent health) to 37 (poor health).
- Katz Index of Independence in Activities of Daily Living (Katz Index; Katz et al., 1970), a brief measure of basic daily functional activities. Scores range from 0 (total dependence) to 6 (independent).
-
Weekly measures (administered to facility care staff by data takers, or via REDCap, at the end of each of the 9 weeks of the study):
- REDCap is a data management tool that provides a secure, reliable web-based interface for collecting, managing, and storing study information.
- AD-RD Mood Scale: a proxy measure of mood (Tappen & Williams, 2008) that yields a positive mood total score with two subscores (spirited, contented) and a negative mood total score with three subscores (hostile, apathetic, sad).
- QUALIDEM: a multidimensional proxy measure of quality of life that examines person-environment quality of life indicators that are specific to persons with ADRD (Ettema, 2007; Ettema at al., 2005).
-
Activity Involvement Checklist: A data taker will ask the activity directors at participating facilities to complete the Activity Checklist regarding the types of activities offered to participants in a typical week, and whether or not participants tend to join in these activities. Note that this tool will only be used once. The facility may also opt to complete this questionnaire electronically via REDCap.
-
Session measures, all administered by trained data takers during participation in either music therapy or verbal discussion:
- Dementia Mood Picture Test (DMPT; Tappen & Barry, 1995), a 6-item self-report measure of participants' feelings using simple face drawings and verbal descriptors. Yields a single score that ranges from 0 (most negative mood) to 12 (most positive mood). Administered before and after each session.
- Menorah Park Engagement Scale (MPES; Camp et al., 2015), an observational measure of social engagement and activity. Yields a profile of six engagement scores, averaged across 5-minute observation intervals. The MPES incorporate items from the Observed Emotion Rating Scale (OERS; Lawton et al., 1996; 1999), an observational measure of facial expressions that indicate basic emotions.
-
Session protocol (music therapy, verbal discussion): grounded in a conceptual framework based in extant literature regarding how the intervention is expected to influence affective, social, and quality of life outcomes. This framework consists of intervention strategies organized within 6 themes: cognition, attention, familiarity, audibility, structure, and autonomy. The music therapy condition consists of live singing with guitar accompaniment by a board-certified music therapist (i.e., MT-BC) using participant-preferred selections. The conceptual framework and accompanying strategies inform how the music is manipulated in real time by the music therapist to meet participants' momentary needs and demonstration of strengths. The verbal condition is designed as a non-music comparison using all of the same strategies and adaptations, but in a non-music context. It consists of live conversation led by an MT-BC using conversation starters centered around age-appropriate, familiar topics. For both condition, sessions will be centered around a main topic (Travel/Places, Nature/Hobbies, & Love/Friendship), each of which will be used in two consecutive sessions in the same order across all participants. Sessions will occur three times per week for two consecutive weeks (6 sessions per treatment). Each session lasts for 25 minutes in the afternoon.
-
"Pre-Study" Week: Practice session (one 30-minute session), the music therapist will practice aspects of both the music therapy protocol and the verbal discussion protocol. Data takers will practice all data collection procedures. Facility staff will gain practice transitioning participants to and from the sessions.
-
Week 1, UT (baseline; AD-RD Mood Scale, QUALIDEM).
-
Weeks 2-3, first randomly assigned condition - either music therapy first or verbal discussion first (DMPT pre/post session, MPES+OERS during session; AD-RD Mood Scale and QUALIDEM end-of-week)
-
Weeks 4-5, UT (washout/return to baseline; AD-RD Mood Scale, QUALIDEM).
-
Weeks 6-7, crossover to condition not yet received - either music therapy or verbal discussion (DMPT pre/post session, MPES+OERS during session; AD-RD Mood Scale and QUALIDEM end-of-week)
-
Week 8, UT (return to baseline; AD-RD Mood Scale, QUALIDEM).
-
Post-study: as a general measure of decline over the course of the study, the PI will re-administer the MoCA. To minimize burden on participants and nursing home staff, the PI will not re-administer any of the other pre-study assessments.
