Introduction: Informal carers of people who have had an ischemic stroke constitute one of the pillars of the state’s welfare system. Individual social support can help solve carers’ health problems and improve their quality of life. The aim of the presented research was to assess selected social services and indicate the importance of this support for self-assessment of their quality of life. Material and methods: Research material included the results a diagnostic survey obtained from 39 informal caregivers of people who had suffered an ischemic stroke. The Berlin Social Support Scales and the WHOQOL-Bref quality of life questionnaire were used. The statistical analysis was carried out with the use of SPSS Statistics 24.0 software. Results: When better support is perceived by the guardian, this correlates with higher quality of life in the social (r = 0.31) and environmental (r = 0.32) spheres. Better currently received support correlates with higher quality of life in the psychological (r = 0.32) and environmental (r = 0.36) spheres. Conclusions: 1. Social support is important for carers’ perceived satisfaction with their quality of life; 2. Satisfaction with personal functioning facilitates essential activities for providing competent care.
