After an initial exploratory linear or lo- gistic regression that eliminated non-signi- ficant variables and those that did not meet the assumptions of collinearity or correla- tion, a stepwise backward regression was performed according to similarity ratio until the variables and the final, best-fit explana- tory model were obtained. SPSS version 25 for Windows (SPSS Inc., Chicago, IL) was used for statistical analysis and G*Power 3.0.0 for statistical power and effect size (26). Results Patient characteristics Patients’ mean age is 40.91 (±10.03), and 62.5% are male. Forty-two point nine percent have completed primary education, 42.9% secondary education, 11.1% are edu- cated to university level and 3.1% have no educational certificate. Most patients (52.7%) are single, 25% are married or in a stable relationship and 4.9% are separa- ted or divorced. The most frequent illness is schizophrenia (53.1%), followed by bipolar disorder (20.1%), schizoaffective disorder (12.5%) and recurrent depressive disorder (8.5%). Caregiver characteristics Caregivers’ mean age is 57.80 (±12.22), and most are female (71%). Forty-one point one percent have completed primary edu- cation, 37.9% secondary education, 10.7% are educated to university level and 10.3% have no educational certificate. The majo- rity of caregivers are married or in a stable relationaship (55.8%), 10.3% are separated or divorced and 7.6% are widowed. In ge- neral, the caregiver is the mother or father (62.5%), followed by the partner (22.8%) and siblings (9.4%). The majority of patients and caregivers (79.9%) live together in the same house- hold. Subjective and objective caregiver burden Tools as FBIS allow to describe the diffe- rents aspects of care. Table 1 summarizes the data obtained for “care for daily activities” and “containment of behavioral disorders”. In care for daily activities, a greater presen- ce is observed in assistance with schedules and times (55.8%), housework (55.4%) and administrative formalities (54%), but in the first two, moreover, the intervention is frequent and annoying. Regarding the con- tainment of disturbed behaviors, it is the containment of suicide risk that requires the greatest presence of the caregiver (in 55.4% of cases) and which, in addition, generates a high level of discomfort (in 43.8% of cases).
