The aim of this study was to confirm the correlation between social support and the quality of life of seniors who live without cognitive disorders, but are living in an institutional environment. The measurement of variables was based on a cross-sectional survey method. A representative sample of 957 seniors participated in the survey. The study covered public nursing homes (NHs) and residential care homes (RCHs) selected for the study by stratified sampling. The results confirmed a linear correlation between social support and the quality of life of seniors (p < 0.001). It was also confirmed that there were differences in the range of studied variables depending on the type of institution (NH versus RCH; p < 0.001). Social support is a significant component, and at the same time, a modifier of the perception of the quality of life for older people. Its variable level determines the subjective assessment of functioning in particular domains of quality of life. RCH as an institution of a social nature satisfies the needs for support at a higher level than NH, which translates into a better perception of older people's quality of life.
