While music interventions in nursing homes and the community have generated promising findings, little evidence of acceptability or efficacy data are available in ALCs. This pilot study tested the acceptability and preliminary efficacy of a staff-led group music intervention among ALC residents with dementia (n=19). We used a mixed-methods pre-post study design. The primary outcome measure was the Cohen-Mansfield Agitation Inventory-Short Form (CMAI-SF), and facilitator focus group interviews were conducted to gain additional insight into intervention acceptability and facilitators/barriers to implementation among activity staff. Seventeen (89.5%) participants completed the intervention with a 77% overall session attendance rate. Results suggest that the intervention is well-received by management, family, and activity staff, Implications for intervention design, efficacy testing, and contextual factors related to implementation will be discussed.
