This study investigates the social networks impact on mental health. Further, it examines the role of digital tools in regard to loneliness among elderly people. Several studies have investigated similar questions before, but further knowledge can be added with this study on the Swedish population. The aim of the study is to enhance the knowledge on whether social networks have an impact on individual’s mental health. The theoretical framework consists of Granovetter’s strenght-of-weak-ties and Putnam’s definition of social capital. A quantitative approach is used, and secondary analysis is made on an existing data set. The data originates from a survey used to measure social networks in Sweden. To get further insight, an ordinal regression model was built in order to sort out the potential impact of the different variables. The result shows that elderly peoplewho use digital tools are less likely to feel lonely in comparison to those who are non-users. Also, both weak and strong social ties seem to have a positive effect on mental health. Finally, social capital is also proved to have an impact on mental health. The most important result show that trusting people was the strongest correlated variable with mental health in regard to the components of social capital. Further, those who feel trust for others are more likely to report a better mental wellbeing. For future research we recommend focusing on a specific age group, for example relevant to our findings, this could be the elder population. To gain enhanced knowledge, we recommend a mixed methods approach in order toget a deeper understanding.
