Abstract
Objectives: We investigated salivary biomarkers of stress, more specifically, cortisol and alpha-amylase, to evaluate effects of individualized music listening (IML) in people with dementia.MethodParticipants were N = 64 nursing home residents with dementia (meanage = 83.53 ± 7.71 years, 68.8% female). Participants were randomly assigned to either listening to their favorite music every other day for a period of six weeks (intervention), or standard care (control). Using the Saliva Children`s Swab (SCS), saliva was collected before, after, and 20 min after IML sessions at the beginning and end of the intervention period for the analysis of salivary alpha-amylase and cortisol. <br>Results: Using the SCS was feasible in people with dementia. Nevertheless, there was no effect of IML on salivary stress markers. <br>Discussion: Although using SCS was feasible, active patient engagement is required. Future studies need to corroborate findings in larger samples. <br>Trial registration: German Clinical Trials Register: DRKS00015641, ISRCTN registry: ISRCTN59052178.
