title: [Is it beneficial to involve family member? A literature review to psychosocial interventions in family-centered nursing].
abstract: BACKGROUND
  Families influence the wellbeing of patients and are influenced by illness themselves. Involving caregivers in patient care was examined in multiple studies.
  
  
  OBJECTIVE
  The aim of this literature review was to investigate the different approaches to family-centered interventions (FI) and to evaluate the tested outcomes as well as the detected effect sizes.
  
  
  METHODS
  This search for a systematic literature review of randomized controlled trials and metaanalyses revealed three Meta Analyses with studies until 2007 and six randomized controlled studies from 2007 to 2012.
  
  
  RESULTS
  FI showed small to middle positive effects on the outcomes depression, mental health, anxiety of patients and family members and on caregiver burden. A conclusive effect on physical health could not be shown. The results strongly depend on the enrolled patient population, the targeted participants of FI, as well as the focus, type and dose of FI. The studies showed vast differences in the length and type of intervention, the target population and the selection of outcomes. Comparing outcomes was difficult due to the use of different outcome measures.
  
  
  CONCLUSIONS
  Further research with various populations, different FI intensity but with same, valid outcome measures is needed.
