The Impact of Educational Intervention on the Anxiety of Family Caregivers of the Elderly with Dementia: A Randomized Controlled Trial.

Participants were recruited by convenience sampling from clinics in Shiraz, Iran, so the findings may not apply to other countries, services, or caregiver groups. Only caregivers with Spielberger anxiety scores above 31 and below 80 were included, so the study does not speak to caregivers with very low or very high anxiety. Caregivers knew which group they were in, and only the data collector and statistician were blind, which may affect self-reported anxiety. The programme combined seven education sessions with four weeks of daily advisory contact, so the contribution of any single component cannot be separated. Follow-up was only three months, which is short for dementia caregiving. The study reported caregiver anxiety only, not patient outcomes, caregiver burden, or quality of life. The intervention was delivered by researchers, lecturers, neurologists, and a book, not by nurses, so its transfer to nursing practice is uncertain.

The supplied text reports no funding source or conflict of interest declaration.

Do not conclude that education sessions alone caused the anxiety reduction. Caregivers also received four weeks of daily advisory contact, and the study did not test the components separately, so the contribution of any single part cannot be separated.
