Background: Informal caregiving is associated with a number of negative effects on carers' physical and psychological well-being. The salutogenic theory argues that sense of coherence (SOC) is an important factor in psychological adjustment to stress. The main aim of this study was to systematically review current evidence on the association between SOC, burden and mental health outcomes in informal carers. Method: A systematic search was carried out up to September 2017 in the following databases: PubMed, CINAHL (EBSCO), PsychInfo (OVID) and Scopus.
