“Electronic databases” were searched in July 2003, including a hand search of reference lists. The Cochrane Library was also searched and an additional hand search of four journals was also conducted.
Study selection and analysis:
All primary research studies with quantitative outcome measures of caregiver psychological health. Search terms were broad and most studies were included. Exclusions: studies in caregivers of people without dementia; studies only reporting outcomes in the person with dementia; interventions involving medication or not based on an explicit psychological model (for example, aromatherapy). Depending on research quality, each study was assigned an evidence grade according to guidelines of the Oxford Centre for Evidence Based Medicine. On this scale, more robust study types (for example, RCTs) score fewer points, with the levels …

This applies to dementia-specific therapy, and to the effects of group and individual caregiver coping sessions on caregiver burden, which were given a grade D for the strength of the recommendation.
