Abstract:

Loneliness is a problem that affects a very high percentage of older people , and can lead to physical and/or mental illness . This article aims to present a systematic review of programs to combat loneliness directed towards the institutionalised elderly . Experimental and quasi - experimental articles published between 2000 and 2016 were included in the review . An analysis was carried out on the quality of the methodological evidence of each of the articles . The programs analysed included animal - assisted , contacts with families through videoconferencing , gardening and/or horticulture workshops , reminiscence therapies , humour therapies , and cognitive interventions . The results show that intervention programs are effective to reduce the feeling of loneliness . The methodological limitations of the studies are discussed and future research is recommended .
