“…[11][12][13][14][15] Social support usually has four dimensions: instrumental support, identified as the provision of tangible help and services; informational support, demonstrated by providing useful information, advice or suggestions to solve problems; evaluative support, inferred by the delivery of information to the other that is useful for self-assessment; and emotional support, which involves the expression of empathy, love, trust and concern. [11][12][13][14][15] With regard to social support, as one of its critical functions of social relationships, it has health benefits at different levels of care, being offered by an institution or person, and when perceived by the recipient in a positive way, it has been considered a protective factor to assist in the treatment of diseases and has a favorable relationship with health effects, that is, it is not enough to offer support to a person, but it must also be experienced as important and necessary by the recipient so that it can be related to positive effects. [11][12][13][14][15] As far as this study is concerned, investigating the association between social support variables in the area of ageing and adherence and barriers to the use of medication probably implies a representative factor in the daily lives of the elderly, since the difficulties identified in adherence and the barriers arising from non-adherence to therapy, especially those related to social support, can compromise functional capacity and the imbalance in the treatment of CNCDs.…”
