"This paper reports the result of a systematic literature review in the field of social media and the elderly. Our study included 36 research papers, selected after an iterative process. Elders are the fastest growing population around the world and any effort oriented to improve their quality of life is important. Our findings show that there is currently no predominant research approach to address this field of study. Samples were generally small and questionnaires were the most common method of data collection. Many of the research efforts are focused on aspects of design, the interaction of the elderly with social media and how it affects their lives. An interesting aspect we found was an informal approach to report results. Many papers do not define social media and an important number do not indicate the research approach nor the number of participants. Another difficulty is to clearly define who is an older adult."
