Experimental study to test the effectiveness of a psychoeducational intervention using virtual reality, aimed at caregivers of multi-pathological and polypharmacy persons to promote safer medication use at home. Experimental design with two groups (experimental and control), pre-post measures, and participants assignment to groups by simple randomization. Null hypothesis. There will be no differences in the frequency of medication errors at home, the severity of the consequences of medication errors, perceived self-efficacy, and health literacy between caregivers using a dosing device (control group) and caregivers using a dosing device with the reinforcement of a psychoeducational intervention designed ad hoc (experimental group).
