Evaluation of a psychoeducational intervention compared with education in people with Parkinson's disease and their informal caregivers: a quasi-experimental study.

The effect of the psychoeducational intervention was not different from the effect of the education programme. The strategies applied in both interventions followed a group approach led by a multidisciplinary team covering information about PD, healthy lifestyles, and social resources. They might be easily sustained in Primary Care to improve care for people with Parkinson's and informal caregivers.
