<jats:title>ABSTRACT</jats:title><jats:sec><jats:title>Background:</jats:title><jats:p>The Dementia Care Mapping (DCM) method is an internationally recognized complex intervention in dementia research and care for implementing person-centered care. The Leben-QD II trial aimed to evaluate the effectiveness of DCM with regard to caregivers.</jats:p></jats:sec><jats:sec><jats:title>Methods:</jats:title><jats:p>The nine participating nursing home units were allocated to three groups: (1) DCM method experienced ≥ 1 year, (2) DCM newly introduced during this trial, and (3) regular rating of residents’ quality of life (control group). Linear mixed models were fit to cluster-aggregated data after 0, 6, and 18 months, adjusting for repeated measurements and confounders. The primary outcome was the Approaches to Dementia Questionnaire (ADQ) score; the secondary outcomes were the Copenhagen Psychosocial Questionnaire (COPSOQ) and the Copenhagen Burnout Inventory (CBI).</jats:p></jats:sec><jats:sec><jats:title>Results:</jats:title><jats:p>The analysis included 201 caregivers with 290 completed questionnaires (all three data collection time points). The ADQ showed a significant time and time*intervention effect. At baseline, the estimated least-square means for the ADQ were 71.98 (group A), 72.46 (group B), and 71.15 (group C). The non-linear follow-up of group A indicated an estimated-least square means of 69.71 (<jats:italic>T</jats:italic><jats:sub>1</jats:sub>) and 68.97 (<jats:italic>T</jats:italic><jats:sub>2</jats:sub>); for group B, 72.80 (<jats:italic>T</jats:italic><jats:sub>1</jats:sub>) and 72.29 (<jats:italic>T</jats:italic><jats:sub>2</jats:sub>); and for group C, 66.43 (<jats:italic>T</jats:italic><jats:sub>1</jats:sub>) and 70.62 (<jats:italic>T</jats:italic><jats:sub>2</jats:sub>).</jats:p></jats:sec><jats:sec><jats:title>Conclusions:</jats:title><jats:p>The DCM method showed a tendency toward negatively affecting the primary and secondary outcomes; this finding could be explained by the substantial deviation in adherence to the intervention protocol.</jats:p></jats:sec>
