Capacity assessment is a research area that focuses on evaluating individuals' abilities and resources to make decisions and manage their own affairs. This assessment is commonly used in fields such as psychology, social work, and healthcare to determine if an individual has the cognitive and functional capacity to make decisions about their own welfare, finances, or healthcare. Capacity assessment may involve assessing various aspects of an individual's functioning, such as their cognitive abilities, understanding of relevant information, decision-making skills, and ability to communicate their choices. The results of a capacity assessment can help inform decisions about the need for intervention or support to help individuals protect their rights and make informed decisions. Overall, capacity assessment is an important research area that aims to uphold individuals' autonomy and freedom to make decisions while also ensuring their safety and well-being.
