This is the protocol for a Campbell systematic review. The objective is as follows: to consolidate the available evidence on attitudinal aspects related to the utilisation of digital technologies in health among older adults. More specifically, we will summarise and systematise the existing reviews findings to identify attitudinal factors that interfere with the use of digital technologies in health in advanced age and to determine whether these factors act as facilitators or barriers. We will also compare the influence of attitudinal factors on technology use behaviour, considering the type of technology in question, and the purpose and context of its use. The overview of reviews questions are the following: (1) What are the attitudinal factors related to the use of digital technologies in health by older adults? (2) Which of these factors facilitate the use of digital technologies in health, and which make it difficult? (3) Are the attitudinal factors that facilitate and make difficult the use of digital technologies in health different for different types of technologies? (4) Are the attitudinal factors that facilitate and make difficult the use of digital technologies in health different for different purposes and contexts of use of these technologies?
